SDAB-107 Rei Kuruki, swapping bodily fluids with an old man: kissing, licking each other, swallowing saliva sex

A pure and innocent young girl who is interested in kissing meets a middle-aged man and experiences intense French kissing. Initially overwhelmed, she becomes hooked on the intertwining of tongues and even licking each other's private parts. They indulge in the exchange of thick saliva, face-licking, armpit-licking, anal-licking...even licking out every drop of sweat, their bodies completely drenched in fluids. They are enveloped in pleasure that melts their brains.
