[Igouno Kanata] Ima, Anata no Tonari ni Iru no. Right Now, By Your Side. Ch. 4

A quiet study session hosted by a young girl in glasses takes a chaotic turn when two classmates and an older male friend crash her "study party," teasing her about her tiny room and revealing an unexpectedly massive erection that leaves her flustered. The innocent charade quickly shatters into a messy, desperate encounter as the girls are overwhelmed by the sheer size of their partner, their small bodies covered in fluids while begging for "more" in a frenzy of pleasure. The aftermath reveals a steamy double session, with the panting, cum-covered girls trying to play innocent as the guy teases them for getting a little "too excited" together.
