A man orders a delivery health service and coincidentally gets an office lady on her first day. Taking advantage of her inexperience, he pretends to guide her while fully enjoying himself. Starting with handjob, he moves on to blindfolded vibrator play, then proceeds to creampie sex using the vibrator. Overcome with pleasure, the office lady forgets about work and starts thrusting her hips eagerly, actively riding him. He reminds her to keep their intercourse a secret before cumming inside her.
