That you are a small dicked loser

Your girlfriend has been imagining that you were the waiter from the restaurant and had been thinking wow this might actually work. Then you said that you were getting close and all she could think was "i can't believe im in a relationship with such a small dicked loser" then she could feel your penis tense up and cum in the condom and she was thankful that you were wearing a condom.

You pulled out and were thinking about eating her out which caused your erection to to grow again

"Hey babe how about a second round?" you ask excited by the prospect

"Whatever you want" she said kinda meekly

"well in the case flip over i wanna try some anal" you say helping her flip over. You take off the condom as you don't need it and are surprised that so much of your cum is still on your dick but decide that it can act as lube. You line your dick up with her ass and are surprised by how big it looks next to her butt. You start to push forward into her ass as she moans. After you bottom out in her she start to fidget a bit and you decide to let her adjust to your dick first before you start really fucking. You notice that she seems to be moaning alot as it feels like she is clenching her asshole around your dick.

"You ready now?" you ask and she meekly replys

"Please be gentle" you start to pull out and then push back in and as you thrust you feel a weird bump in her ass that when your dick pushes past she moans a lot. You decide to use this to your advantage and start to fuck her faster but making sure that you keep hitting that small bump in her asshole. With each thrust she is moaning clearly getting closer and closer as you hear her scream.

"Oh god yes, make me your buttslut." as she screams it her asshole grips down on you like a vice pushing you over the edge as you shoot your load directly into her asshole. You pull out of her ass and watch as the cum leaks out of her ass and down onto her small balls and tiny dick. Wait her what you think to yourself.

"Uh babe, something happened. you have a dick now" you say unsure of how she would react
