Oh you’re going reverse bro. He’d be too pussy to ask Kyle out. Even though there was some sexual tension between him and Kyle in the past, Cartman convinced himself he was just projecting.
Tweek was practically clinging to Cartman after a few redirections of his acting and maybe a midsummer night’s dream stage kiss. Cartman’s technique was so flawless in the acting that Tweek wanted to see how it was for real.
Once they got sexual Cartman wouldn’t be holding back at all. He’d raw the poor twink and Tweek would barely be able to handle it. That kind of intensity would scare the shit out of Tweek and he’d keep trying to get Cartman to treat him delicately. But Cartman’s impatient with him. He’s insistent on getting his way. That’s why they don’t work out in the end.
End game, Tweek can’t handle Cartman the way Kyle can. Including his intensity in bed.
