Yumi Yamada, a slender married woman in her twenties, is approached after dropping her five-year-old child at daycare and lured to another location with a fake survey. Though happily married, she admits money is tight. Offered cash for the panties she is wearing, she agrees to sell them and strips on camera to prove they are hers. When the man asks to inspect the fabric, his hands wander over her body until the young mother becomes aroused. Despite having a husband, she greedily sucks another man’s cock and has sex with him through a creampie finish.
