With only one month left before retirement, famously sensitive Miho Nana abstains for a month to heighten every sensation, then faces a nonstop gauntlet of 100 orgasm challenges. Pills, liquid aphrodisiacs, oils, restraints, fingering, vibrators, mass toy play, blindfolded domination, spanking, teasing, huge cocks, deep throat, frenzied fucking, spit-roasting, deep cervical pressure, squirting sex, bound standing doggy, mounted presses, cum-covered thrusting, and lightning-fast pounding escalate into a massive orgy. She squirts, convulses, and slips into a dazed state under peak pleasure, showing an overwhelmed orgasm face unlike anything seen from her before.
