You play with Sophia in public

One of the things you find fun about Sophia is that she needs to keep the fact that she's your slut a secret. She's your slut, but she's not your girlfriend. She knows that she needs to keep up pretenses. Emma is your girlfriend and she is Emma's best friend.

You find yourself at social events with Emma and Sophia regularly. Now when you're at a bar or house party together you are sure to cop a feel at any moment. You love touching her when other people are around. You might slide a hand on her thigh at a restaurant or slowly run your hands down her body when you move past her at a crowded bar.

You're all out dancing for Isabella's birthday party - it's a large group - and you pull Sophia to the dance floor to join you and Emma. Your cock is already hard from Emma's cock grinding so you grab Sophia from behind and grind your crotch hard against her ass. Emma is behind you rubbing her tits against your back. You see a few of your friends watching the show, but it's dark and crowded, so people can't stare too easily.

You run your hands up and down Sophia's body, stopping to get a good handful of her tits. You hike her dress up so you can touch her bare thighs. Sophia's not wearing panties or they'd already be exposed.

When your cock is about to break through your pants you pull away from Emma and drag Sophia off the dance floor towards the restroom.

You pause in front of the bathrooms. "Which one?" you ask.

"Women's," Sophia answers so you drag her into the women's restroom.

There are three stalls in the bathroom, only the middle one is free, so you lead her in there, bend her over the toilet bowl so she's bracing herself against the back of the toilet, whip out your cock and start pounding away. You love that your slut Sophia is bent over a toilet - it is appropriately dirty.

The two other people in the bathroom (mercifully just peeing) are instantly aware of what is going on. One of them quickly finishes up, sure to tell all of her friends what she heard, but the other is more curious and actually climbs up on her toilet seat so she can watch some of the action, but you never saw her for you are too focused on pounding the slut in front of you.

You had been pretty worked up so you came pretty quickly. You decide to pull out and shoot your cum on Sophia's ass. As always it was a huge load. She's trying to catch her breath after the excitement as you watch your cum dribble down her ass crack. Some stops at her asshole, but some of the cum continues to roll down until it finally drops to the ground from her pussy.

You put your dick away and walk out, leaving Sophia in the bathroom stall. You don't even bother to close the door behind you.
