As I was telling her that her didi will soon become pregnant and thus she will become aunt, she asked me what is pregnancy. I told her women get a bum...y stomach when they are about to deliver a child. She was shocked. What she told me next was totally unbelievable. She said up till now she thought babies were born by magic and were given to parents by fairies.A 18 yr old girl saying this was no less than a shock. But she explained that her sister told her this when she asked her how babies are. Helen asked me coyly why she would like to meet this guy and I said ‘just think about it’. She got the idea pretty quickly and was soon asking what it was all about and what exactly we were going to do. When I slipped my hand down the front of her pants and squeezed two fingers into her dripping wet cunt she certainly knew what was going to happen. I jerked her wet lips till she almost exploded and she screamed she can’t wait. She pulled my hot dick out and pulled it so hard I nearly shot my. I am not going to complain. Who doesn’t want two gorgeous girls pressing their bodies against theirs?The dance isn’t as awkward as I imagined it would be. It is just after the ballroom dance segment of gym class ended, so the DJ occasionally plays ballroom songs. I fumble through some other dances but don’t feel comfortable unless it is a slow song or ballroom. Thankfully there is a lot of slow songs since it was a Valentine’s dance. Carol and Dahlia keep me fairly busy.There are a few other. She was fucking tight! And wet, and hot. She was slowly riding me, pushing my cock all the way back so that the head was pressing hard against her cervix, then she'd reverse direction until my cock was nearly falling out of her pussy.Again, she make wonderfully slow strokes, then speed it up, and I loved the sound of her ass slapping against the wall, and when she sensed I was about ready to cum, she'd slow down to a painfully slow pace. I didn't know how long I could keep this up, but I didn't.
