Rurudo making Koyori drug you and Towa up
for most optimal breeding performace
cause Rurudo is craving some grandchildren
and maybe some Towa siblings

Koyori wanted to watch her handiwork
it slowly devolves into 4some when the room fills with the odor of steamy sex
making both of the kemonomimis horny
and making their bodies sweat out pheromones that make it even worse
while you pound Towa in doggy style, both kneel at your side
Rurudo fondling your nuts while Koyori fingers your ass, using some aphrodisiac-laced lube
both switching between kissing you on the lips and teasing your nipples
and trapping your hands between their thighs, right against their bushy cunts
making you feel the rain forests between their legs, absolutely soaked
after you paint Towa's insides white, the drugs make sure you are still erect and ready to go
at which point Rurudo takes you and demands you fuck her fast and hard in missionary
her legs immediately lock around your torso, making you work hard for each thrust, building up sweat
at while points Koyori leans closer, sniffing your pit
then moving your hand up and burying her face in it, giving it a lick over and over again
also resuming her prostate massage
meanwhile Rurudo pulls you closer, clawing on any part of you she can reach and leaving behind bloody scratches
she makes you cum twice inside her cunt, at which point strength leaves her and lets you move away
Koyori then pulls out a needle from somewhere and injects you again
you feel weak, collapsing, but still erect
Koyori uses your state to worship your sweaty bod freely, licking you basically from head to toe
especially around armpits, crotch and ass
then mounts you in cowgirl
riding you slowly, treating you as an actual toy
telling you how happy she is with your performance and her work on the "boosters"
keeps riding you until you start to crush from the sexdrug high, feeling tired and antsy
once it wears of completely and you go soft, Koyori gets off of you and cuddles you on the floor, rubbing your body with her fluffy tail
