David knew it would go to hell the day his wife's step-mother moved into their home. His secret addiction to masturbating over the idea of sleeping with her could only be made worse once he started sniffing her panties... and wearing them. When she catches him mid-wank in a pair of her satiny, red panties, she declares him a sissy girl and threatens to tell his wife if he doesn't do what ever she says. This means cleaning up after other men have their way with her, playing water sports, and humiliation without giving him the thing he wants most: his mother-in-law to take his seed.
