You don't hold back

You keep pounding and pounding fully sheathing your cock deep into Yangs asshole going deep into her and the more she tries to push your cock out the tighter she gets making you want to fuck her more as you gather all of her hair into your fist and tug on it to get leverage on her like a horse as you fuck her as Yang grunts and pants and cries out in pain but soon enough she starts to let out little moans as well

"Your starting to like this?! Hahaha! What a fucking slut!!" You say and laugh at her making Yang grit her teeth angrily but also blush red in embarrassment as she's actually starting to feel good

Yang-"Fuck fuck fuck! He's so deep! Ugh he's so deep!!!" She thinks and you noice her pussy is getting wetter and wetter and also how your getting closer to finishing in her ass

You can slow down and maybe play with Yang for longer, break her down in pleasure until she wants it as well, or you can just satisfy your lust and leave it at that
