Holy shit I am so sorry but I am back for more

Sae and Rin getting into an argument while Shidou watches because he’s obviously not going to interfere. Why would he? Anyways, Rin gets really angry and forgets who he is arguing with and ends up slapping Sae. Sae doesn’t let this slide and he punishes Rin. Shidou joined in because he wanted to and it was hot, but he just disguised it by saying that the punishment would he even better if Rin had to take 2 dicks.
If Rin slaps Shidou, Shidou would probably jokingly hit him back. Sometimes, Shidou would be flabbergasted, and then let Rin storm off to who knows where. Rin feels guilty eventually so he lets Shidou have some of that ass to make it up to him.

After Rin was gangraped, he got pregnant. Sae walked in on Rin hunched over the toilet and looking distressed. Rin tries to shoo Sae away, and tells Sae that he’s okay and nothing is wrong. Sae gets upset at Rin because he knows that his little brother is lying to him. He knows that Rin is lying because he found the pregnancy test in the trash can…which Rin did not do a good job at hiding.
WHO GOT RIN PREGNANT AND WHO GANGRAPED HIM??

I might never leave you alone. You’re stuck listening to my ideas until the end of time
