Rei appears once again in "Adult Vinyl Book," embodying her sex philosophy of "soul-to-soul connection," just as she did previously. She passionately engages in intense tongue-kissing to fully erect the penis, and even as pre-cum leaks out, she accepts deep vacuum blowjobs, her face twisting into an obscene ahegao expression—her fervor hardly befitting that of an active nun. Furthermore, the scene where her tight ass is forcefully penetrated conveys her remarkable expressiveness and burning passion.
