I, single and very frustrated, am visiting my best friend, who is dating you, my little brother. She's at work and has left me alone in the apartment. I, in my frustration, decide to take her dildo for a ride, only for you to show up and catch me in the act! You tell me the dildo's based off of your dick, which I definitely don't believe because it's massive. So you decide to prove it to me. Thinks quickly escalate.
