“Straight” faggots are always like this at first - they’re nervous and scared and shit at giving head. The alpha will soon force that out of him. Head against the wall being brutally facefucked.
It’s the same when it comes time to fuck ‘em. Stay clothed like in the gif, but make sure he’s naked from the waist down, legs spread wide. The alpha ignores any protests while the alpha works his cock all the way inside. As the alpha starts to fuck him, it’s now important for the alpha’s buddies to then come in. The alpha says something like “Hey guys, he seems to really like cock up his ass. Want to watch?“
Still dealing with the recent loss of his cherry, the straight faggot is confronted with the humiliation triple whammy: the unmanly “stuck” feel of a dick up his ass for the first time; having legs spread, exposing his junk in front of clothed men; and the realization that there are witnesses to him taking cock up his bum.
The shock of the triple humiliation will overwhelm the part of his brain that might find a way out. He won’t think of trying to get off the dick penetrating him. Tears will come to his eyes as the men call him names as witness to his degradation. And he won’t resist when the alpha shouts out “Fuck! Deep up his ass! Watch how he takes my load. Fucking faggot ass just sucks up the cum.“ He’ll keep his ass firm against the alpha, until the alpha chooses to pull out.
After, standing there surrounded by clothed men, his ass dripping cum, he’ll be vulnerable and open to the two-ended gangbanging that’s bound to come. Even if not right then, then very, very soon…
How fortunate that there are alphas willing to train “straights” to be the faggots they were always meant to be.
