Sister In The Basement

Late night I went down to the basement to see what my big sister was watching on TV. She had it on some cable channel soft core sex movie. When I saw that I said sorry and
started to go back up but she said it was ok, I could watch too.

I have to admit it was exciting and not long my cock was making a tent out of my boxers. I should have been embarrassed with my sister next to me but
being a really horny teen I was not.

Once in a while I would look over at her, she was wearing these loose fitting silk shorts and had her hand down them touching her pussy, I could not believe we were playing with ourselves together.

She turned down the TV then asked if I would want to see her pussy. I knew it was wrong but really wanted to see a real live bare pussy so I said yes. We both took off our shorts, she
moved to the edge of the couch and I got down between her legs. I intently looked at her pussy covered in black pubic hair, thick lips and watched her spread them open so I could see
very wet looking pink folds.

She asked if I would want to stick my dick into her pussy. Honestly I did but I was scared. My Sister told me she was on birth control then added she had only let the guys fuck her with a condom and really wanted some bare winnie sex.

So I kneeled between her legs and put the tip of my cock against her spread open pussy lips. My heart was pounding as I gave a little push and the tip disappeared into her body, we
both watched it slide all the way in. It was so awesome to feel her very wet and warm pussy completely surround my cock. When I pulled back a bit my cock was all wet looking from
her juices.

My sister put a hand on my lower back and opened her legs wide as I stroked in and out. I wish could say I lasted a long time and fucked her brains out but it was likely only a minuet or two. I she could tell I was about to cum because she held me tight so I was deep as possible when I squirted several huge blasts of cum.

When I pulled out cum leaked out of her open pussy and made quite a mess. Later she told me that when she fucked a guy with a condom it just really made her more horny so once in a while she would come into my room after a date to fuck me. I should have been grossed out that she just had sex but it kind of turned me on more.
