Chapter Text
been thinking a lot about rinniki threesomes, and since i enjoy a bit of nikimayo and can appreciate the potential that rinnemayo has, it's the perfect combination. i imagine a rinnemayoniki threesome would consist mostly of rinne and niki spoiling mayoi, who's squished between them. well, less spoiling on rinne's part and more using mayoi's hole as a fucktoy, but i digress. niki's in the front, selflessy ignoring his own hard-on to tend to mayoi's cock (as if he needs any extra stimulation, with how rinne's ruining his hole.)
rinne's roughly stretching open mayoi's hole with his cock while whispering filthy things in his ear. occasionally rinne will shut up and put his mouth to good use, sucking and biting marks into mayoi's pretty skin, which makes him whimper louder as tears well up in his eyes.
niki's a bit more gentle, but the pleasure is unbearable as he pumps mayoi's cock, maybe even using his mouth when he's not busy pressing soft kisses along mayoi's skin. and since niki is the (unofficial) king of oral, all mayoi can do is moan and whimper, babbling incoherently about how good it feels or in response to rinne's teasing.
of course, mayoi is the first to cum, crying and bucking his hips involuntarily as he spills all over his tummy. niki is eager to either swallow it or lick it up off of mayoi's stomach. unfortunately for mayoi, rinne isn't even close, so the poor boy will be thoroughly overstimulated and brainless by the time rinne finally cums inside him, grunting obscenities into mayoi's ear.
poor niki hasn't finished yet, but he doesn't mind taking a turn at mayoi's hole, his aching cock sliding in with ease as rinne's cum leaks out. he's still comparatively gentle, but now he's the one whispering in mayoi's ear, switching between praising him and lightly teasing him. regardless, rinne certainly enjoys the show as he jerks off to the sight. once he's close, he pushes his cock towards mayoi's face, cumming all over his pretty face as mayoi's weeping cock drools another load onto the sheets beneath him. niki, thoroughly enjoying the sight, finally finishes inside, stuttering out a few more words of praise to mayoi as he adds to the collection of cum pooling in mayoi's hole.
