nsfw-sin:

i love monsters so: someone dragging a merman up onto the shore where he cant get away and prying his groinal slit open so they can fuck into his ass/genital pouch roughly and they cant do a thing abt it. theyre out of the water, floundering, with a big guy straddling their tail and fucking them…mmm

honestly the reverse would work great too though. a horny merman dragging a hapless sailor under not to kill them on purpose but just because theyve certainly got a tight hole to fuck

*clangs pots and pans together* DAT MERMAN RAPE THO 

poor helpless merman on shore *rolls on ground* yaaassss

always having those mermen taking advantage of humans. But the other way around is also *eyezooms*
