We're just friends. It won't be weird for you to do some nude modelling with me so I can get extra credit for my art class. I need it.... and as my friend, you wouldn't just let me flunk that class and not be able to get my degree, right? It will only be weird if we make it weird. But you start making it weird when you get an uncontrollable boner from seeing your long-time best friend naked. You didn't think you'd get turned on. You don't think of her that way, do you? But something about seeing her bare and looking up at you with those eyes.... The professor asks you two to get into a more "intimate" pose". Your best friend sitting naked in your lap drives you crazy. But you keep your cool.... until your dick accidentally slips into her. You apologize, trying to wiggle out of it, thinking she's going to be so mad.... but she mischievously starts rocking her hips back and forth against you, so slight that the classroom full of students doesn't notice. But she's only playing with you. She doesn't actually want to fuck you, she's just a tease. But you can play that same game. So you give her the same treatment, but harder and faster. She's stunned that her best friend is having sex with her in front of everyone. And managing to keep a straight face. The class ends before either of you finish. No big deal though, right? It was just some teasing, to annoy each other. Although while you're both getting dressed, she notices you're still erect. The dynamic of your friendship changed the moment your dick went inside her. She wants you now. A quick, hard fuck in the art room before the professor comes back. That's what you need to finally unleash those pent-up feelings of desire you've had for her. Watching your best friends getting railed by your cock is too much for your senses and you cum inside her without thinking. Maybe you can still be friends....? **INCLUDES: friends to lovers arc / romantic vibes / emotional / sneaky sex / virtual sex / dildo fucking / dirty talking / begging / moaning fetish
