Sibling Adventurers and Brother's Seeding Bed Corruption

"Sis...come to your senses..."

A lone boy moans in a dark cavern, bound by tentacles.

"Hehe, shall we start, then?"

His sister stands before him, warped by pleasure.

"I'll just have to modify you before you become big and strong..."
She whispers.
"I'll turn you into a good girl who feels pleasure just like me..."

And so the boy's corruption into a feminized seeding bed begins...

A tentacle-filled body-modification manga.
