Fuck Sarah in the ass

Well, no reason to let Kevin have all the fun. You might as well get in on it too. You unzip your pants again and head back to the stall you found Kevin and Sarah in just a second ago. Both of them notice you this time, but it doesn't look like they're going to stop making out. When she sees you undoing your belt, though, Sarah looks up at you and nods.

You drop your jeans and your boxers and push up Sarah's dress, revealing her perfect ass and thong. Next you pull down her thong, and your dick pushes right up against Sarah's asshole. Sarah sits up a little straighter, but her only real reaction is a smile as you push your hard, thick dick all the way into her ass.

This is a little strange. You never would have guessed that your first time with Sarah would be fucking her in the ass in a bathroom stall while she made out with a different guy. But hey, you're not going to complain. Her asshole around your dick feels as good as her ass looks, and she's moaning while she kisses Kevin.
