So it's basically about this guy that visits his family tribe that seems to be going extinct of smthn. So, his people (only women) have a rose birthmark and currently there are only males living in the island, you get the idea.
Our MC, let's call him Idiot McUke. Idiot McUke sails across the sea to his island and realizes that he'd forgotten his belongs after the boat left. So now he's stuck. Unfortunately, he meets a guy (Seme) that basically rapes him and invites his bros to gang rape him.
Plottwist: Idiot McUke actually has a rose mark on his bum cheek! And he had 0000 idea. Which means he can get pregnant even though this isn't omegaverse. The Bros rape him for the 13452th time and get him preggo. Bro 2 likes bro 3. Idiot McUke is in love with his RAPIST (Seme). All brothers fight on who'll be the father. after 9 months, Idiot McUke is due, but NOOO. Apparently, there was a HUGE STORM COMING. And the doctors count come for that reason. So the bros had to do it themselves.
Idiot McUke gives birth to FREAKING Three boys that have rose marks. And the bros decid that the best thing to do after he gives birth is to RAPE him in front of his children. Oh yeah, we can also breastfeed. So the bros play with his... Uh.. To test him.
Does anyone remember the name of the Yaoi where the guy gets transferred to a island and he has a rose on his butt and then he has three triplets
