家事に育児、PTAまでも完璧にこなす遙だったが、一つの出来事をきっかけにして、ただの牝へと堕ちていく…。
快楽と罪悪の先にあったのは、崩壊か!?
それとも真実の愛か!?

My favorite book from sink finally got digital release!
It contains several short stories and one bigger arc with a mother & younger sister NTR!
And still has no english translation. :(

Thanks genl for his help!

If you liked it, please support the author by purchasing their works!
For real, he is a really nice guy who is surprisingly communicative with his fans on his twitter page and knows some basic english.

the daughter doesn't get fucked in this one, who the fucked tagged oyakodon, what she does in the story is rape her mother along with the ntrerers, not sister ntr at all
