[Suzan] I'm Forever In Your Debt! (Towako Oboro Emaki 15) {Mistvern + Bigk40k}

A pure-hearted, defenseless youkai girl driven from her native home is saved by a gentle salaryman who offers her a delightful and shameful cohabitation life in return for her forever debt of gratitude. Petite and horned with a soft, slender body and sensitive curves barely contained by a loose kimono and later a tiny bikini and glasses, she throws herself into repaying Iida-san with eager, moaning cunnilingus and insatiable cowgirl hips that chase her womb's sweet spot until the thin apartment walls can barely contain her cries. Between tender promises to learn modern living and breathless punishment where she rides him to creampie-filled exhaustion, their sweet trust spirals into a relentlessly lewd domestic bliss that teases just how far her grateful devotion will go.
