Yumina Hirosaki, a 28-year-old married woman with an addiction to extramarital affairs, finds herself surrounded by male performers, visibly ecstatic. She's utterly obsessed with cock—so much so that when aroused, her saliva flows uncontrollably, drooling constantly as she wildly loses herself in pleasure. The sight of her happily jerking off a slobber-covered cock reveals her as a hopeless nymphomaniac, endlessly stimulating viewers without a hint of restraint. She even begs, "Hit my ass harder," pushing her limits further. Her back turns bright red from the relentless spanking, and she's fucked over and over until her mind and body collapse into complete exhaustion.
