A beautiful big-breasted woman estimated to be a G-cup, working at a design company. She has a cool, mature appearance, but her armpits are surprisingly sensitive. When an erect cock rubs against her, her nipples instantly react, showing her intense arousal. After not feeling a cock in a long time, she sways her large breasts in pleasure, fully savoring the sensation. She receives her first-ever armpit creampie, and her reaction is spectacular—a moment that brings her sensitivity to its peak.
