[Ecchi Ecchi Daifuku (Neko Daifuku)] Getting Cum in Every Orifice... For Science! [TsukiNet]

A petite, soft-bodied test subject with small breasts and a quivering, sensitive body is restrained in a futuristic lab as a cold, clinical machine promises to fill every hole with endless semen for science. Mechanical nozzles lock onto her tight ass, slick cunt and womb, then push relentlessly into her gasping mouth and delicate nose, announcing each connection and discharge while flooding her until her belly distends and she dissolves into drooling, cross-eyed climaxes she cannot escape. With the sealing process complete and her vitals slated for two weeks of continuous monitoring, she is left suspended in nominal, overflowing ecstasy, begging to discover how much pleasure and humiliation one restrained body can endure.
