The Futa Sleepover

TW: possible rape. After meeting this girl named Sabrina at a few parties, you became friends with her, though you did something a bit strange: from the getgo, you lied, saying you weren't attracted to women in hopes of being invited to the fabled girls' slumber party. And it worked. Sabrina invited you to a sleepover with her friends Lucia, Gwen, and Lindsey. But what you may not realize is: at one of said parties, Sabrina actually overheard you blabbering on about your plan, so she was sure to invite her futanari friends exclusively. And she was keeping a secret from you too: she's a futanari herself, meaning you're in a room full of cocks and have no idea. She intends to make you pay for your pervy intentions, but will her more wholesome friends go along with it?
