Both of them.Mom didn't freak out.I shook my head at how this surreal, amazing day just got even stranger.The next twenty minutes, we didn't say a wor.... Just enjoyed the afterglow of an amazing intimate moment between siblings.Dad announced, "We're here."I leaned forward and whispered, "That was amazing."She nodded, as she leaned back into me and ground her cunt on my cock one last time.Once stopped, Kristen quickly opened the door and got off of me before Dad could see.I quickly put my cock. So I'm sitting there and we had some small talk about how hot it was and what I was going to do with the rest of summer. Then she stretched her legs out straight and arched her back and the top of her bottoms pulled down so far that I got a hard on and I didn't even see anything. Next she stretched her arms over her head and sure enough her entire tits popped right out and she held the stretch for almost half a minute. She had sun glasses on so I couldn't see if she was looking at me or not.. When people asked what I wanted to be when I grew up, I said "fashion designer"!Even in the early years of elementary school, none of the boys wanted to associate with me, and as a result I was always something of a loner. Fortunately I got along OK with some of the girls... and with Andrea, who was my only real friend. Andrea and I looked surprisingly alike... not just because of the close family resemblance, but from the fact that we had nearly identical hair styles. This was the mid-1970s,. The first night it did not bother me as much but now I was willingly kissing her in public around other people. She had called me girlfriend in front of other girls; they all knew that I was dating another woman. She had even made me say she was my girlfriend in front of our friends. That was sort of mean, although it felt good to admit that I had feelings for Maria. When she defended me it made me feel so warm and proud inside.I changed into my PJ's and tried to sleep but I couldn't I just.
