[4K equipment brings you lewd, stiff nipple climaxes!] Mami-chan is so popular for her sensitive nipples, yet she's so innocent, so we did our best to make her cum over and over again. Aphrodisiac application boosts her lewd mucous membrane, she snaps her nipples, she climaxes with restraint nipple stimulation, and she squirts with nipple stimulation pistons... Mami-chan, who was once so innocent, has become a sex beast who can only think about cumming. We recorded 3 scenes and 5 scenes in high quality that clearly shows the state of her nipples as she climaxes to such an extent that it makes us worry!
