Big Sister, Big Brother – Erotic Shishi Gumi

Synopsis

A sister with huge breasts and an equally huge appetite can’t find a lover.

A brother whose endowment is so large he keeps getting dumped by girlfriends.

What’s more, the sister has a unique constitution where she lactates from her breasts when experiencing pleasure.

One day, the brother discovers that in addition to his sister’s impressive bust, she also has an exceptionally large vagina—and realizes she’s the only one for him. The sister becomes convinced that only her brother’s massive member is compatible with her body.

Thus, brother and sister seek each other’s bodies, repeating sexual encounters day after day, until the sister finally becomes pregnant with her brother’s child…

Every highlight scene is rendered in dynamic, realistic After Effects animation at 30 frames per second.
