[Fujiyoshi] Tomodachi no Nee de Douteisoushitsu (COMIC Magnum Vol. 38) [q91]

A seductive blonde woman declares she'll take the virginity of her friend's sister, Yuuyu, while two eager boys lie helpless on the bed. She teases Shunpei‑kun next, and the scene escalates with a frantic threesome where the female dominates, her ample breasts and wet body glistening as the boys gasp and climax. The tension peaks as she revels in the thick, innocent reactions of the virgins, promising more while the boys plead for mercy.
