Mommy Daddy -No Milk’s Coming out of My Nipples!-

Natsuki's first love was his private tutor, Ryogo. Unfortunately, he ended up marrying Natsuki's sister, Yukiho. Years pass by, and all Natsuki had to console himself were dirty fantasies of Ryogo. That is, until Yukiko disappears, leaving Ryogo to take care of their twins. Ryogo asks Natsuki to help with raising them, and so beings their life together under the same roof!

Natsuki becomes overwhelmed by pent up desire and unreciprocated love. A long time of getting off clutching Ryogo's discarded clothes makes a sleepy kiss quickly turn into a heated hip-grinding affair.
