I thought so too, but I remember there was a shadow scene where they had the silouette of the smex, doing it doggy style.
Oh the randomness I remember
Oh it has a scene like that too - did we find it ? owo

All I remember is that Omega is a college student who spends his heat in a brothel made for omegas. One of his friends who is an alpha girl buys him before he meets his dated pair. And they show a weird scene of the girl doing him... Random, I know. But any help would be appreciated!!!
