When a young man gets home one evening after work to find his home flooded out by a burst pipe he accepts an offer of a bed for the night from the divorcee next door. He's always viewed the older woman as just a friendly neighbor, but revises that opinion when he goes into the bathroom to find her panties hanging on a line.
The sight of them excites him and he can't help playing with them, but forgets to lock the door. When the divorcee walks in on him he expects to be thrown out, only to find that the sight of him using her panties turns her on. She takes off the pair she is wearing to help and then lets him have some fun with more than just her panties.
