My Girlfriends Twin Brother

I couldn’t sleep at all last night thinking about all the variables that could occur during our work out Session. In fact I had a terrible day at school too, nothing went right and I was getting more anxious, as each hour passed. At 3 pm I bid Roberta farewell at her club with a quick kiss and told her Rob and I would be working out today, as a smile came to her face as if relieved he was getting back to his workout routine.

I met Rob out by the gym, gave him a fist bump, and we walked quietly at first toward his house. The anticipation of what to say, and who would say it was so thick you could cut it with a knife. I finally said “So, You want to talk?” he said “Yeah, …about last week…….. Uh…. I’m sorry”, Dude, I don’t know what came over me.” Then a brief silence again as I said “Well it wasn’t all you, you know, so I guess I’m sorry too.” Then brief silence again as we continued walking, Then he said, “But it was good for me, I mean I liked it”. Then I said “Yeah me too, it’s cool dude, don’t let it bother you. In fact I’ve been checking you out since our first workout together”. He replied “Ha… I thought so”. I told him he had a pretty nice dick and that blow job was amazing and kind of with pride he said "yeah I thought so myself". Then he slid into a less serious mood and jokingly said “but your cum blinded me”, I laughed and said “I still had that barbell mark on my abdomen”. We gave each other a shove and it was like all the tension was gone.

We got to the house and Rob turned away from me as he changed, I thought that was weird, I mean, I had his dick in my mouth just the other day. But we changed and began our routine, only today I noticed he was wearing briefs under those short shorts. He seemed to be more competitive with me today than usual, each time trying to outdo me, when finally I couldn’t lift the barbell anymore and he had to help me get it back on the stands. I dropped my hands to my sides in sweaty exhaustion when he leaned over the barbell and slid his hands into my shorts. I surprisingly looked up at his crotch approaching my face and as his hands touched my dick, I slid mine up his leg and under the briefs touching his. Damn it’s happening again! This time he stood and pulled off his tee shirt and dropped his shorts and briefs to the floor and then he reached for my hand as he pulled me up off the bench sliding my tee shirt over my head as I lowered my shorts.

We slid down to the mat and embraced in a kiss, I had never mouth kissed a guy before, but I could feel his dick rubbing into my stomach as we did, and it was hard as a rock, as he jerked back and forth rubbing it on my soft abdominal skin, I could feel his soft blonde pubic hair brushing against me. I just wanted that moment never to end. We continued to explore each other’s tongues and slightly bit down on each other’s lips pulling them apart, as I let my hands wander down to his sides grabbing those firm buttocks, as if pulling his hard dick closer into my stomach. He moved his hands to either side of my head, pulling me in for a long steady holding kiss before he moved to my neck, actually creating a hickey. I didn’t care, I was in ecstasy, he released me, rolled around and began kissing his way down my chest with his knees on either side of my head, the closer he got to my dick the closer his dick got to my face. That big gorgeous thick pink cock was getting bigger and bigger as it got closer and closer to me, until I couldn’t take it anymore and I raised my head sucking it in like a straw, forcing his full body weight onto my chest. He sucked me off as I sucked him and we both attempted to face fuck each other. I raised my hands up to his butt cheeks and pressed them into me forcing his dick further into my mouth, without realizing it I bottomed out and Robs dick was headlong into my mouth, and I wasn’t choking, but I did have to gasp for breath as his dick head throttled in and out of my constricted throat tissues, and today my saliva glands were secreting excess snot like fluids, lubricating the hell out of his member. Rob was face fucking me even harder forcing every last centimeter into my mouth as he screamed like a baby that he was Cumming and he pumped several volleys of cum into my throat, I didn’t even pull him off this time and he didn’t withdraw, I felt his warm jisim mixing with my spit as he eventually began to withdraw and I mixed the textures in my mouth coughing some out of my throat back into my mouth, as I held in and savored the salty but bitter like taste on my tongue , and I tried to swallow my own salvia around his globs trying not to allow any additional to go down with it. Rob regained his composure and went back to work on my dick, again the competition came into play as he tried to outdo me, he was bound and determined to do me one better, as he worked my shaft with his mouth and hand twisting it with one hand and the other reaching under my balls to my ass crack, I finally shot one hell of a long stream into his gut before several short volleys began throbbing in his mouth. He swallowed immediately coming off licking every last drop possible. We turned toward each other and I opened my mouth still holding whatever remained of his seed, as I allowed it to drip in strands to the mat below, as I wiggled my finger in the slime spreading it in small circles.

He stood and headed toward the bathroom as he tossed me a towel, he came out wet and dripping as he began to dry his head and I headed in to shower. We dressed and both sat on the bench and began to talk. Both seemingly with regret we asked ourselves “what did we do?” and agreed this was the last time, we can’t do this again. And for the first time Rob acknowledged I was his sister’s boyfriend and he can’t let this come between us all. I agreed but admitted I thought I had more feelings for Rob than for his sister and I wasn’t sure how this could not happen again. But we agreed we just couldn’t.

With that we heard someone upstairs and it was Roberta coming home, we went upstairs and all watched a movie in the living room. It was hard because while Roberta was sitting next to me kind of flirting and cuddling on the couch, I would look across the room at Rob just sitting there and our eyes would meet, and we’d smile at each other. I knew he was hoping beyond hope we would do it again just as I was hoping it would.

We had normal workouts for the next week, with only passing comments, but Roberta was upstairs. When the following Wednesday came, Rob and I both were acting kind of weird, both knowing that we’d be alone for a few hours. Well we went downstairs and Rob began to change, only he didn’t put on his shorts, he stayed naked, so I in turn did the same and we both began working out naked. We spotted each other and looked for excuses to touch each other’s naked body. To our surprise we both were very restrained and for all practical reasons it was a normal workout, that is, as normal as naked can be. Then our rest time came and we both sat on the mat facing each other, Rob with his leg up stance, as his cock and balls were just sitting there, I finally had to reach over and grab it as he reached for mine, and said again “Last time”.

We proceeded as before only we got to be a bit more daring and he flipped me over on my stomach and began rubbing his dick in my ass crack, it felt good and I didn’t stop him. I felt him get harder and harder and his breathing increased. I spread my legs in turn splitting my cheeks apart allowing his dick to go further down into the forbidden valley, until he stopped and searched for my hole, I instinctively wanting it to happen, reached back and spread my checks with my hands, Rob spit a glob of spit and began his slow pressure accent into my hole. He only got about 1 inch in and it was too painful so I tightened up and he couldn’t get in, so we switched positions and I tried on him, and oddly I slid right in, oh so tight and warm he was. I was inside him and he seemed to enjoy it, not a peep out of him, so I began pumping and I was thoroughly enjoying myself as I watched his hair flop back and forth as his face rubbed back and forth on the mat, and suddenly I felt the need to Cum and I pulled out shooting my load all over his back. I scooped up the cum, rolled him over and deposited it on his dick as I attempted this time to sit on his dick, as he steadied it under my hole, my cum lube was enough to get past the point of no return and I slid right down on him holding my breath and biting my tongue, as my ball sack brushed lightly back and forth across his peach fuzz blonde pubes. I began bouncing as he was giving grunt sounds with each bottom out, then it happened, he didn’t tell me, he was close and I felt his warm lubricating cum coat my inside passageway with slimy cum, but I also didn’t stop because I was on the verge of Cumming again myself, and when I did I fired several volleys onto Robs chest with as much power as my first load earlier. But now Rob came inside me, I was scared and he was overly apologetic and could only hope we didn’t do something we would regret, but we were young and didn’t know any better. Once again we cleaned up in the shower only today we cleaned each other together, dried off and now it was like this was our secret, we weren’t doing anything bad or wrong, we were justifying our actions as our secret. Upstairs we went and Rob thankfully stayed with us, so as I didn’t have to get sensual with Roberta today.

When it was time to leave Roberta gave me a hug and kiss, but Rob walked me to the door and out the front walk, saying, we either need to stop this or tell his sister, I said let’s just keep it our secret for now, after all it wasn’t wrong right? We were just getting each other off. Yeah that’s it.

That night at home in bed I felt guilty, guilty as hell, again I didn’t sleep, why was I justifying it’s not wrong, I owe Roberta more than that, but how do we continue without someone getting hurt, the longer we go, the worse it will be, neither of us is out, hell I don’t even want to admit we did it, and somehow I kept convincing myself I was straight, just curiosity and experimentation. It’s a phase I thought, oh hell who am I kidding I like dick.
