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.
