Tom is a highschool senior whose sister, Pam, has been gone off to college for two years. On a visit home, Pam has a date with her former boyfriend, Rod, to try to rekindle an old romantic flame. When she comes home, she's frustrated, she finds Tom jacking off to a porn film, and she suddenly lets Tom know what she wants.
I'm sure my sister is no different to anybody else's. She's reasonably happy to wander about the house in her bra and knickers, I suppose she doesn't really see me as being male for I am two years younger than she is. On a couple of occasions I have even caught her walking from the bathroom to her room wearing just a large bath towel around her waist and a smaller one around her wet hair
