The Cheating is not between the Main "Couple" though. They do look good, and the smut does too but basically, this whole thing started as taking advantage of a drunk guy, and somehow turned into them becoming fuck buddies behind the Bottom's girlfriend? It's weird. It's bad. It's such a shame that the art looks good.
