[Hijiri Tsukasa] ONA-ASHI 6 My Junior Is My Masturbation Assistant (ONA-ASHI! ~Ero Mangaka no Onanie o Tetsudau Shigoto~ 6)

A bespectacled, big-breasted college junior becomes her senior’s paid masturbation assistant, straddling him, stroking his cock, and taking his cum as their teasing exchanges blur professional and personal. Her playful confidence grows into open desire when she calls herself his “sem-pay” assistant and insists that she is happy to keep doing the work. The mood is intimate and mischievous, centered on her teasing dominance, his eager reactions, and the growing possibility that the arrangement matters to both of them.
