Craig and Tweek are exes who see each other again at a party, they start to argue over something petty but things get heated. Tweek is making cocky remarks, trying not to pay attention and texting people while Craig is taking him from behind and trying to get reactions out of him, both of them hate to admit that they're enjoying it. Turns into a who fucks better contest and they probably make up after
Craig/Tweek, hatefucking (orgasm denial/edging, dirty talk, degradation)
