Goodbye Morals! Busty Lab Girl Becomes Sex Toy in Intense R&D Double Penetration
As Yumi's morals completely collapse in this erotic tale by artist Mogiri Ochigi from the fictional Secret R&D Circle, the rough translation captures every gasp and moan during the intense product testing. Strapped down in the lab, her voluptuous body quivers from the men's expert hands—probing her slick folds with fingers, then escalating to throat-deep blowjobs and tight anal invasions. The MMF dynamic peaks in double penetration scenes where sex toys amplify the pleasure, her glasses fogging up as waves of ecstasy overwhelm her. Big breasts bounce wildly under nipple clamps, while clit stimulation pushes her over the edge into submissive bliss. This 137-page English doujinshi builds a gripping story arc of bondage and group debauchery, leaving no fantasy unexplored. Fans of sole female adventures will crave the raw intensity.
