It's simple, women almost non-existent and he's been obsessed with Seonho so probably he never has sex all these months (?) and we know Seonho got sexy body so it felt pure bliss he finally managed to get his hand on Seonho. Lube is hard to find maybe so thinking he prepping Seonho with his tongue probably means getting Seonho ready for him and he can nut asap. For sex crazed guy who hasn't have sex for months, it felt really euphoric probably.

For the regulars, why are his eyes as big as golf balls while he’s licking MC’s ass??? It’s giving me extreme fomo. Like what’s between those cheeks that’s making his eyes go so wide?? And what am I missing out on in life???
