(You're Tweek) Christophe and Tweek were sleeping, cuddling each other, then Christophe wakes up and he blushes because Tweek's wearing a shirt that shows his belly (Tweek's not wearing pants because of his imp legs) and Christophe touches Tweek's bally, then Tweek turns around, while sleeping, and Christophe starts kissing Tweek's belly

Christophe: M-Mmmm....~

Christophe grabs a ciggarate and he starts smoking it while kissin Tweek's flat belly
