In the dimly lit ER, Nurse Mika Kojima awaits Dr. Ryo Sayama's arrival. She's been naughty, using her vibrator during her shift, and knows he'll inspect her pussy. Dr. Sayama enters, his eyes immediately drawn to Mika's damp panties. He fingers her, making her squirm, then guides her onto his cock in reverse cowgirl. Mika grinds on him, her ass slapping against his abdomen. He flips her onto her back, fucking her hard, before pulling out and painting her stomach with his creamy load. Mika rubs it in, her pussy throbbing with unquenched desire.
