Too late.

You were so shocked by the sight of your sister's rapidly approaching form that you neglected to let go. In one sort of painful and very wet instant you were pinned against your sister's taint by your girlfriend's testicles. After a few seconds you saw a stream of light break through the darkness and a gust of fresh air whipped over your form. You tried to move, but your sister's juices had you stuck to her skin.

Your girlfriend was in ecstasy. The tight prostitute wrapped snuggly around the entire length of her shaft had wiped all thought outside of getting off. The thoughts of her boyfriend were completely erased from her mind. She just had to pound this little whore until she had her fill.

Your sister was just as enraptured by the thick hard cock that was currently kissing her cervix. Usually she gets some little dick prick, but today she got a massive cock from a beautiful, and kind of familiar looking, woman. Good thing she's on the pill, because she is going to ride that dick until she can't think anymore.

Your small break from your sweaty sex filled cell created by your sister's ass and your girlfriend's balls was short lived. Only a fews seconds later the familiar sack came swinging back at you at an even greater **** with a loud SMACK.

This went on for about 20 minutes before the first wave of cum filled your sister, which started slowly started seeping out and running right down all over your body. After the second shot, the cum caused you to slide down and get wedged right between your sister's butt cheeks.

There you stayed as your sister and girlfriend fucked themselves silly.
