At first, I thought it would be a futanari story, but no, actually, it’s heterosexual sex O_o
Featuring, a bit more than half of the time, Reisen, a super-babe with bunny ears, and bit less than half of the time, Tewi, a pettanko with small weird tits.
Besides that, frankly there’s very little to say. The two bunny girls pick a human, and the mating begins, for the rest, it’s entirely up to your tastes! Personally, I didn’t care for the pettanko, but Reisen was totally worth it in my eyes ^^
A side note, I ran a light retouching on the images, on a few pages what ought to have been black was just grey.
