Garage Sale

So my sister, roommates and I have been having a garage sale. We try to make it fun, play some music, sit outside, try to work on our tans... So, in walks this little perv and heads straight to the bra and pantie sets we had... The little perv walks over to the baskets and starts rubbing the panties in his hands! One of my smart ass girlfriends asked if he liked the way they felt with a sly flirty smile on her face. He smiled and nodded. Of course she takes it a step further, saying "Then show me how you'd use them to make it feel even better." Getting a kick out of this and really curious to see how far this was going to go, I walked over and traced my finger down my low cut top before putting my finger tip in my mouth, swaying back and forth, giggling to encourage this behavior. He said that he'd pull his cock out, rub on the panties till he shot it right into the panties. Can you guess what happened next? My sister closed the garage door and all three of us made him pull it out, get on his knees and jerk off in the panties. The whole time looking down on him, laughing at him trying to hold his cum in, while he stroked his small prick on my friend's silky panties. He just couldn't seem to cum, so we made him stand up and put them on like a good pantie puss. That little fucker watched me and my sister kiss and that was all it took... he came all over inside the panties, standing there like a messy sissy with his cum soaked panties stuck to his cock. We all started laughing while our new pantie slave got himself together again. Embarrassed, but satisfied, he walked out the garage door...
