So this is the story of the very first time I shared my girlfriend. During college, I started dating this sexy blonde, she was a 10, with a beautiful body and perfect, perky tits. When we started out, the sex eventually became increasingly kinky – we would talk dirty about anything that possibly could come to mind. It evolved into talk / fantasy of sharing her with another guy/ cock. She was very reserved as far as this at this point. But she loved riding my cock and whispering in my ear fantasies of getting two cocks, what she would do with them. On the fourth of my junior year, we randomly went to this lake to camp and boat, with my older bother and his friends and randoms. We were becoming increasingly kinky at this point, and at my behest, she wore the sluttiest bikini top out our first day. Her 34D tits were wonderfully on display in this little top. Only the nipples were hidden. I was loving all this guys staring and drooling at them all day. We did some C, which only made everyone stare more and get hornyer, and I was loving seeing them stare at her perfect tits. After the day of boating, we all came in shore and jhang out for a bit. My gf, we'll call her Mary, and I had been dirty talking all day, wanting her to show her perfect tits off if the time was right. The general crew there was a little underwhelming. We had the dirty idea to ask my older brother if he wanted to go back yo the water, there was some rouse. He agreed, obviously feeling the sexiness Mary was putting off. We walked down to the shore, wearing only our bathing suits. We got in the water, and me and my brother began trying yuk get Mary to take her top off. She was so shy then. After much cajoling, she slowly unclasp her top, and dropped it into the water. Her perky tits were genuinely glistening I. The wet night. We took turns urging with her and hugging against her. To be honest, it was an incredible turn know for my older brother to be touching my gf in that way. We decided to get out of the water and sit on this pontoon boat. We got her to sit between us. I then told her she should let him fuck her. I was rick hard thinking if the possibility. But she had already dropped her panties and qua grinding herself on his huge erection. More….
