My girlfriend and I had been together about four years at this point and her brother was living with us. She and I had an open relationship but we had not done anything with family members. Until now.
He and I were in his room getting stoned in front of the open window while my girlfriend was in the kitchen cooking. We were relaxing and talking as the smoke took effect. I was very relaxed and lay back on the bed as he was changing the CD, he put on some heavy metal. He came over and sat next to me on the bed and was talking about the band. He turned and looked at me and got this funny look on his face. He then leaned back on his arm next to me and with his other hand he ran his fingers lightly along my jaw. I stared into his eyes and he leaned down and kissed me lightly on the lips.
I was struck motion less for a second thinking OMG I can’t believe her cute 20 year old brother just kissed me ( I was 33). Then I realized I was getting hard and I wanted more of this cutie. He rolled over a little more towards me and kissed me again with more force this time. I reached down and felt his cock growing hard in my hands as we were making out on his bed.
He reached down and was rubbing my now hard cock and said he always wondered what it would be like to have sex with another guy. We went back to kissing and rubbing each other’s cocks. When we started humping each other’s hand I knew I wanted to suck his cock.
I reached down and undid his pants and pulled them and his underwear down just far enough for me to pull his cock out. I admired his cock it was a good looking cock for five inches, I leaned over and ran my tongue up and down his cock. I couldn’t stand it for long though I had to have this cock in my mouth so I took the head of his cock in my mouth and started to suck on it as I moved my head up and down the length of it. I started slow and was slowly building to a faster rhythm, he was propped on his elbows and watching me suck his cock and after about two minutes he said he was going to cum.
I started to bob my head as fast as I could and he grunted as he gushed a thick spurt of cum into my mouth, at this point he grabbed the back of my head and shoved it down onto his cock and held me head there as he spurted more cum into my mouth. God how I love for a man to hold my head and use my mouth for his pleasure. He collapsed back on the bed when he was done and I pulled my head up and swallowed his load and looked at him and said “Tasty” and proceeded to lick his cock clean.
He pushed my head away and said “It’s a bit sensitive and I need a minute”. He then pushed me onto my back and grabbed my shorts and underwear and pulled them off of me as he got between my knees and proceeded to lick my cock as I had licked his. “I can’t tell you how badly I have wanted to do this with a guy but especially after my sister said you were Bi”.
I was surprised since he was always making homophobic jokes, I guess he was overcompensating. I reached out a hand and pulled his head to my cock and he opened his mouth and took my cock in. I am 6.5” and a little thick but he managed just fine. He copied what I did earlier and started slow and then built up to a faster rhythm. I was lying on my back with my hands behind my head and watching him suck on my cock and enjoying the buzz from the smoke. I thought this is the best feeling in the world.
It was at this point I realized I was getting a blowjob from my girlfriend’s brother while she was in the kitchen and we did not even close the door. If she had walked down the hall she would have seen us, hell she would have heard us moaning and groaning if she had walked near the hall.
I was so horny to begin with and I love blow jobs. Add to that it was from my girlfriend’s brother and with the door open I would probably get busted. It was all too much and I squirted a huge load in his mouth and keep squirting. It was the hottest orgasm I had in some time.
When I stopped squirting he pulled off of my cock and looked up at me and said that just as much fun as he thought it would be. He stood up and I saw he was still hard, I slid off the bed and was sitting on the floor between his legs looking right at his cock.
I took his cock in my mouth and started sucking as fast as I could, I had my hands on the sides of his thighs for leverage. He reached down and grabbed my head as I was sucking his cock. This went on for a few minutes and he grunted he was cumming again. I kept sucking for all I was worth as he shot another load into my mouth. As he stopped squirting in my mouth I slowed down knowing he was sensitive know that he had cum.
He surprised me though as he grabbed my head more forcefully and started to fuck my mouth. I held on and slurped like a champ as he shoved his cock in and out of my mouth. This went on for a few more minutes and then he grunted again he was cumming. This time was doing a body spasm/twitch as he shot another load into my mouth. I was holding onto his thighs still and was very excited about the whole kinky and perverted thing we were doing. I was so excited that when he started to squirt in my mouth I also started to squirt my cum all over the floor without even touching my own cock.
I pulled myself up and sat on the bed and he leaned down and started to kiss my again, he pushed me back on the bed and lay onto of me with our cocks rubbing against each other. We made out for awhile as he ground his still hard cock against my semi hard cock. Finally he stopped as my cock started to get hard again and said if we don’t stop now he will want to go all day.
It was a good thing he some rational thoughts because I am such a cock/cum slut I would have been his for the rest of the day.
As we were getting dressed again he said that was so hot and so much better than he fantasized about. I agreed it was great and hot. He kissed me again and said thanks for making his fantasy come true. He said we should go see what his sister was doing.
As he walked out of the room I was dumbstruck, here I was 12 years older than this kid and he took charge of me and used me for his fantasy and I let him. Hell I enjoyed it and even came without touching my own cock. Needless to say I sucked his cock whenever and wherever he wanted after that. Fortunately he was a giver as well and sucked mine just as often.
I never did tell my girlfriend about us, not even after we got married. I kept right on swapping blow jobs with him.
