[Mikawaya] The Story Where the Gal in the Upper Caste of the Class Turns Out To Be a Cosplayer (COMIC Megastore Alpha 2019-07) [desudesu]

Ichikawa, the tanned queen at the top of the class caste system, lures her quiet lower-caste classmate Koyabu into a karaoke hangout that exposes her secret double life as a cosplayer—stepping out in a frilled corset and gloves that barely restrain her huge breasts. The stunned virgin barely has time to stammer a compliment before she pushes him down and mounts him, her sweaty body riding him through climax after climax while she teases him about how hard and eager he still is. When the room timer finally runs out, she milks one last load from him with a wicked grin and suggests continuing at a hotel, winking that the night has only just begun.
