Eric must comfort his sister through one of the most difficult times in her life but can he control his own lust long enough before they do something they may regret
Gossip Girl - My Sister
He hadn’t touched a woman since the divorce. Months of deliberate isolation in this studio had left him unused to contact, unused to warmth. The divorce had left him hollow in ways he still had not sorted out. Now his palm rested against his sister’s bare skin, warm and trembling under his palm, and his body had reacted before his mind could stop it. The loneliness he had been living with suddenly had a shape, and it was her.
Eric kept his hand moving in slow, careful circles across her back, trying to stay steady for her. He looked down without meaning to.
The white undershirt had ridden up while she lay on her stomach. The hem sat high enough to show the thin panties she wore underneath, the soft red fabric stretched tight over the full curve of her ass and disappearing between her cheeks. Barely covering anything. The same round ass he had just watched on the screen, the one marked with a red handprint and spread open for the camera, was right here under his hand.
He tried not to think about it. He focused on the sound of her breathing, on the way her shoulders still shook. But every slow pass of his palm across her back tugged the shirt a little higher. Each time he caught a clearer glimpse. The sight went straight through him.
Fuck. He was so turned on right now it hurt. His cock had never gone soft. It kept thickening inside the boxer-briefs, the thin cotton doing nothing to hide the shape.
Serena suddenly lifted her head from the pillow.
“Eric?”
Serena’s voice was quieter this time. She had turned her head on the pillow and was looking back over her shoulder at him. His eyes were still low, fixed on the space between her thighs. The second he realized she was watching him, he jerked his gaze up to meet hers. He swallowed hard, the sound loud in the quiet apartment.
She held his eyes.
“Do you think less of me?”
That was not what he had expected her to say. The question landed soft and raw, full of real fear. Eric’s mouth opened and closed once before he found any words.
“Uh… no. Oh god, no.”
Eric kept his eyes locked on hers. The words came out rough but steady.
“Serena, you’re beautiful. There is nothing in those photos or videos you should be ashamed of. Nothing.”
Her lips parted.
“Really?”
“Really.” He leaned in a little without realizing it. “He… he made you do it. He took something beautiful from you. Something so private and intimate… and that bastard is trying to use it against you! To blackmail you with it!”
Serena’s face crumpled. Panic flooded her eyes.
“If that gets out I will be ruined. I will be called a slut. Fuck, I called myself a whore!”
The raw fear in her voice hit him hard. He wanted to make her feel better. He wanted to take every bit of that pain away.
“But you’re not,” he said, voice low and firm. “That was all just dirty talk, right?”
She nodded, small and shaky.
Serena’s voice came out softer than before.
“Thank you. Thank you for believing in me.”
“You know that I will always have your back, Serena. Nothing will change that.”
His hand kept moving across her back in slow, absentminded strokes, the only comfort he knew how to give.
Serena’s eyes closed. It felt better than it should have. Safer. Warmer. Every pass of his palms sank tension out of her muscles and replaced it with something softer and more dangerous. She shifted slightly under his touch, her hips pressing into the couch without her meaning to.
This is Eric. These are Eric’s hands.
The thought should have cooled her. It did the opposite. A slow ache began to build between her legs, steady and insistent. She bit the inside of her cheek and stayed quiet, letting him keep going, even as her breathing grew shallower and her body grew warmer under every stroke.
Serena let out a soft breath.
“God… your hands… they feel good.”
“Yeah?”
“Yeah.”
Eric hesitated only a second.
“Do you want a massage? You… you had a tough night.”
She nodded against the pillow.
“That would be nice.”
He stood up from the edge of the couch. Serena’s eyes dropped before she could stop herself. The thin boxer-briefs did nothing to hide how hard he still was. The thick outline of his cock tented the front, heavy and obvious. Her gaze lingered for a heartbeat too long before she looked away again.
Eric climbed back onto the couch and carefully straddled the backs of her thighs, keeping most of his weight off her. His hands settled on her shoulders and began working the tight muscles there, thumbs pressing in slow, firm strokes.
Serena spoke after a moment, her voice quiet and rough against the pillow.
“It didn’t start like that. He used to make me feel safe. Special. Then the control started and I just… kept trying to fix it. I thought if I gave him what he wanted in bed he would stop being so cold the rest of the time. The camera was his idea. He said it turned him on. I let him film it because I was scared of what would happen if I said no. The things I said, the way I acted… I was just trying to keep him happy. I hated how it made me feel after. Like I had given away pieces of myself I could never get back.”
Eric’s hands moved lower along her spine, still steady, still careful, while she talked.
Eric’s hands pressed into the tight muscles of her lower back. Serena shifted under the pressure, her spine naturally arching so that her ass and chest lifted slightly off the couch. A soft, low sound left her mouth.
“Mmm, god, your hands are magical.”
Eric watched her stretch under the pressure of his palms, her back curving like a cat in a long, luxurious arch as a soft purr left her throat. The movement flexed her ass and lifted it higher, the thin fabric between her thighs stretching tight across her. The soft, puffy lips of her pussy pressed against the material, the cleft between them clearly outlined and now on full display only inches from him. He could not take his eyes off her. Every dirty image from the folder and the video flashed through his mind in rapid succession—her bare breasts, her mouth stretched around a cock, the way her ass had looked when it was being spread open. He could not stop the pictures no matter how hard he tried.
He forced his hands higher, away from the dangerous view, and dug his thumbs into the knots along her shoulders instead. His voice came out shaky and unsure.
“I can’t believe he forced you to do those things on camera.”
Eric leaned forward to work a deeper knot near the base of her neck. The shift dropped his hips and pressed the full, hard length of him against the soft curve of her ass. His fingers still felt good on her shoulders, but it was the firm girth grinding into her nether region that pulled the low moan from her throat.
Serena’s breath left her in a quiet rush. Her fingers curled into the couch cushion. She did not speak. She only pushed back the smallest amount, a helpless roll of her hips that brought him more firmly against her. The thin fabric of her panties did nothing to hide how wet she already was.
Serena’s voice came out soft and rough against the pillow.
“He… he didn’t force me. I… I wanted to. I wanted him to want me like that.”
Eric’s hands stilled for a second.
“Like what?”
“Like I was his personal playboy bunny.”
The words hit him straight in the gut. His cock jumped hard against her, the rigid shaft was gently grinding into the soft give of her ass. The sudden movement drew another quiet sound from Serena. He was almost certain he had just heard her moan.
She felt it. Hard and unmistakable against her through the thin cotton of his boxers. Serena went still. Her breath caught. For a second she could not move or speak. Heat flooded her face and then dropped lower, sharp and unwanted. She whispered his name, barely audible.
“Eric…”
“Yeah?”
She did not pull away. She stayed there, feeling the thick shape of him and the way her own body answered it with a slow pulse of warmth she did not want to name. Her mind raced, trying to catch up with what her body already understood. She should stop this. Instead, she let out the smallest, helpless sound that left her throat.
“Lower,” Serena begged. The shortness in her breath made the single word sound delectable.
Eric’s hands traveled slowly down the length of her spine. At the same time her hips rose just slightly to meet the downward grind of his. The shift lined them up perfectly. The thick head of his cock pressed directly into the soft mound between her thighs, only the thin panties and the strained cotton of his boxers between them. The pressure forced the head of his shaft past the open flap of the boxers.
When the damp heat of her soaked panties met the head of his cock, something final gave way inside him. The last clean version of her blurred. Eric’s breath turned rough. He let himself press harder, dragging the thick head through that wetness, and the thought that followed was simple and irreversible: She wants this. She’s wet for me.
“Stop. You have to stop this”, her mind screamed.
Her body ignored the thought. Another slow grind of her hips answered the pressure of him, and a soft, shaky sound escaped her before she could swallow it.
A low “Mmmm”, half whimper, half sigh.
The soft, broken whimper that left her mouth rewrote everything. He wanted more of those sounds. He wanted them louder. He wanted them while he was inside her.
His hand moved before the thought had fully formed. The small button slipped free. The flap opened. His cock sprang heavy and flushed into the open air and settled against the soaked crotch of her panties. Eric looked down and watched the flushed head of his cock press right between the soft lips of her pussy, only the thin, damp panties stopping him from sinking into her. He felt a dark, steady satisfaction roll through him. He had chosen this. He was going to take it.
“Eric, please.”
His fingers trailed lower, thumbs sliding along the full curves of her ass and spreading her just enough to see everything better. The sight of her like this, face down under him, his bare cock nestled against the thin fabric that barely covered her, felt like every dark dream he had ever tried to kill.
“Please what?”
Serena suddenly goes still, her voice came out shaky and needy.
“Please don’t stop.”
He could not believe what he was hearing. He could not believe what was happening. Even if he had wanted to stop himself he knew he would not have been able to.
Eric’s thumb slid beneath the edge of her panties. Serena’s whole body tensed. She said his name again, low and rough.
“Eric…”
It was not a protest. It was a plea for him to lead her open and waiting body.
Eric’s thumb dragged across the thin, soaked fabric of her panties and pulled the material firmly to the side.
That was it.
Nothing left between them.
The hot, bare head of his cock rested directly against her freshly trimmed pink pussy, sinking just slightly into the soft, slick folds. Heat met heat. He felt how wet she already was, how ready. A low, involuntary sound left his throat.
Serena felt the cool air on her bare skin the second he moved the fabric aside—then the blunt, burning head of him pressed against her. Thick. Heavy. Inevitable. Her hips lifted the smallest fraction, an involuntary offering she couldn’t stop. She kept her eyes shut and her mouth pressed to the pillow, breathing hard, every muscle in her body locked on the edge of the choice she was already making without words.
He pushed.
The head of his cock breached her and the world narrowed to that single point of impossible heat and pressure. She was tighter than he expected—soft, resistant, perfect. A sharp, broken gasp tore out of her as he opened her, the thick crown forcing her walls apart.
“Oh—fuck—”
Eric watched himself disappear into her, watched her pink lips stretch obscenely around him as he claimed the first thick inch. Then another. Every slow push felt like a victory he should never have been allowed.
Serena felt the difference immediately. He was so much thicker than anyone she had taken before. The heavy stretch burned in the best way as she clenched around his shaft. Her hips lifted on their own, pushing back, trying to take more of the massive flesh that was spreading her wide.
He kept going—slow, deliberate, relentless—feeding her another inch, then another, until she was trembling beneath him and the only sound in the room was her shaky, open-mouthed breathing and the wet slide of him claiming what was now his.
“Oh fuck! Oh god, you’re too big.”
Eric rocked back and then forward again, the wet sound of her pussy taking him filled the room, broken only by her sharp gasps and the broken words she could not hold back.
“I feel every ridge of you. Fuck, Eric, you’re stretching me open.”
He knew. He watched it happen in awe, eyes locked on the place where her pink lips were forced taut around his cock as more of him disappeared inside her.
“Do you like that?” Eric asked, pushing forward.
“Yes,” she whimpered.
He pulled all the way out until only the head remained. Then he drove back in with one long stroke, burying every inch of his cock inside her.
“Fuck, you’re so tight, Serena.”
Serena’s walls fluttered hard around him as she gasped, the sound breaking into a drawn-out cry.
“Fuuucckkk, you’re so deep.”
Her ass lifted clean off the couch as she took him to the root. Her tight little asshole clenched shut and her pussy gripped him in hard, rhythmic pulses while a low groan left her throat.
“Fuck, you take me so well, ” Eric said with a grin on his lips. Eric drew his hips back just slightly, adjusting the angle, then drove forward a little deeper. Serena felt the blunt head of him press against her deepest point and a helpless moan spilled out of her.
“Eric…,” Serena groaned, needy. The same Eric van der Woodsen who used to hang back at every Constance party and every Upper East Side event while she and Blair ruled the room. He was the last person anyone would ever expect to make her feel like this.
His long, thick shaft ground deep inside her as another moan slipped out. Her breath came short and uneven while she looked over her shoulder at him.
“Oh god, Eric, this… this… this is so bad.”
His eyes locked on hers. He knew that things between them would never be the same.
“I know,” he said.
She cut him off before he could say anything else.
“But it feels so good.”
The look she gave him was pure heat mixed with the last scraps of guilt. That was all the permission he needed. Eric pulled back and slammed back into her in one hard stroke again.
“Ohhhh god, Eric… hnf!” The words left her as part moan. “Wait, stop. Stop for a second.”
Worry dropped straight through Eric’s chest. Fuck, he really had crossed a line. He slid out of her carefully, already ready to apologize. He stood, his mind racing through every possible way he could have misread her, every sound she had made, every time she had pushed back against him.
Serena moved onto her knees on the couch, knees pressed into the cushions, head resting against the backrest. Her ass faced him completely. The position left her open and waiting, her pussy glistening.
Her mind would not stop racing. Want and desire tangled together so tightly she could barely tell them apart. She knew exactly how wrong this was and still she had put herself in this position for him, ass up, open, waiting.
His confidence returned quickly as he realized she was offering herself to him willingly, eagerly. Eric stepped forward. It was the exact dark fantasy he had never allowed himself to finish in his head, now real and right in front of him. He wrapped a hand around his hard cock, dragged the thick head up and down through her soaked folds.
As she felt the head of his stiff tool drag through her heat and split her lips apart, her heart best faster with anticipation. A moan slipped out of her before she could stop it. Her ass lifted higher on its own, begging for more.
When he finally pushed inside, the feeling rippled outward through every nerve. The delicious stretch of him forced a broken sound from her throat. His hands settled on her hips and pulled her back onto each thrust like this was the most natural thing in the world.
Serena moaned loudly. Every time he sank into her another sound left her mouth.
Fuck, he felt perfect.
He leaned over her, mouth close to her ear.
“You feel that? How deep I am?”
Serena only moaned.
“Answer me.”
“Yes,” she managed.
“Yes what?”
“Yes… I feel it… I feel you inside of me.”
His hand slid under her and found her clit, rubbing in slow circles while he kept fucking her.
“You’re soaked. You’ve been soaked since I touched you. Tell me the truth. How long have you been this wet for me?”
Serena’s voice came out shaky. “Since… since I felt how hard you were.”
“Good girl.”
Eric looked down at Serena. Her firm ass rippled each time his hips connected with her. He spread his palms across both cheeks the same way the man in the video had done, opening her so he could watch every inch of his cock claiming her, her muscles clenching and fluttering so he could feel every part of her.
“Serena, do you like this?”
“Mmm hmm,” she answered, the sound short and breathless.
He raised his hand and brought it down in a light smack across one cheek, copying the video.
“Ohh… harder. Please.”
Fuck, she was begging. Eric thrust forward hard enough to make her yelp, then raised his hand again and spanked her with more force. Her pussy clamped down on his cock even tighter as he drew back. A long, low moan poured out of her.
He delivered another firm slap across her ass and held still, buried deep.
“You want more of this?”
She pushed back against him in answer.
“Use your words, Serena.”
“Please,” she breathed.
“Please what?”
“Please keep fucking me. Please don’t stop.”
Eric grinned, fingers digging into her hips, and slammed back into her to the hilt. Again and again.
“Oh god. You are so thick. I can feel every ridge of you sliding out of me.”
Fuck, his sister was such a dirty little slut.
His pace picked up. The sharp sting of his hand on her ass only made her want him more. Eric’s hips drove into her faster and faster, each thrust forcing her voice higher until it broke into raw screams. Her hands pressed hard into the couch cushions as she pushed herself back onto him, trying to take every inch of that thick cock as he crammed it deeper.
“Oh god, yes, fuck yes!”
She groaned and he gave it to her exactly like that, more, deeper. Her body clenched around him. The tension coiled tighter and tighter low in her belly until the words started tumbling out of her mouth without permission.
“Fuck me, Eric. Please fuck me. Don’t stop.”
The begging sounded so wrong, so absolutely wrong, and yet she was so close she could barely breathe. Slap! Another hard thrust. Slap! He railed her deep and relentless, his cock sliding all the way in and all the way out in long, punishing strokes.
His voice had lost almost all of its earlier hesitation.
“Look at you. Taking your brother’s cock like you were made for it. Tell me how it feels.”
“It’s so thick,” she gasped. “Oh god I love how you feel. It feels so fucking good.”
“That’s right. You’re going to be mine!”
Serena’s knees buckled. Her eyes squeezed shut. Her fists locked white-knuckled against the fabric of the couch. The pressure inside her reached a tipping point.
He grinned as he watched her, “You’re going to cum, aren’t you?”
“Yes—”
“Say it properly.”
“I’m going to cum on your cock, Eric. Please… make me cum.”
He gripped her hips hard and drove into her without mercy.
“Cum for me. Right now. Let me feel it.”
Her orgasm exploded through her like a wave that started at the exact place where he stretched her open and then crashed outward in violent pulses. It was so hard it felt like the forbidden moment itself had cracked something deep inside her open. Her pussy clenched and fluttered in helpless waves around Eric’s thick cock, milking him as her whole body shook. A broken, high cry tore out of her throat. Her arms gave out and she collapsed forward against the back of the couch, still trembling, still gripping him with every rhythmic spasm while the aftershocks kept rolling through her.
Eric watched her in disbelief. Serena’s body still quivered in the aftermath, small aftershocks rolling through her in soft waves. Her voice came out broken and high as she whimpered into the couch, the sound of pure pleasure.
“Oh god… thank you… Eric… fuck…”
Serena’s body continued to tremble. Small aftershocks fluttered around his cock. She kept her face pressed to the cushion, breathing hard, trying to find any steady thought.
I came. I came so hard for him. Harder than I have for anyone. The realization sat heavy and electric in her chest. She felt ruined and safe at the same time.
When she finally spoke, her voice was quiet and rough.
“Eric…”
“I’m here.”
She swallowed. “I didn’t know it could feel like that.”
He stayed still inside her, one hand stroking slowly down her spine.
“Neither did I,” he said.
A long moment passed. Then Serena shifted her hips the smallest amount, still sensitive, still wanting.
“Don’t pull out yet.”
He stayed buried inside her, one hand slowly stroking down her spine. Neither of them spoke. The only sounds in the small studio were their uneven breathing and the distant murmur of the city beyond the window.
Serena’s body still trembled in soft aftershocks around him. She kept her face turned into the cushion, eyes closed, as if looking at him too soon might make the moment real in a way she wasn’t ready for. Eric could feel every small flutter of her, every residual pulse that pulled at him. He didn’t move. He didn’t dare. Part of him was still stunned that this had happened at all. The rest of him was already aching for more.
Outside, the Upper East Side continued as if nothing had changed. Inside the narrow apartment, everything had. The blackmail, the video, the years of careful distance—all of it still waited for them. But right now there was only the heat of her body around his, the quiet weight of her trust, and the knowledge that neither of them was finished.
Serena shifted again, the smallest roll of her hips, and a soft, needy sound escaped her throat.
