I'm talking to my friend about how different life is now that our step-sons have gone off to college. I'm feeling sad that you don't come and visit me enough and am jealous to find out that my friend and her step-son have stayed very close. She lets me in on the secret - she's been having sex with her step-son and it's kept him coming back for more and more! I'm not sure it's a good idea but she says all the step-moms are doing it, it's just kept hush hush. You're coming round to visit me this weekend, so I decide to give you a visit you won't forget...
