She's the picture of an intelligent mom who rocks glasses, but beneath that facade lies a monstrous pervert who can't resist her son's unyielding cock! Posing as a strict mother, Hikari teases her son Sho's crotch while he studies, saying, "With something this big, you can't possibly concentrate..." She then mounts his erect cock, grinding away relentlessly even after he cums, refusing to pull out and continuing in a brutal, non-stop riding position, reaching her own intense climax! Hikari Mom's endless, masterful control over his ejaculations! #SquadLeader.
