Good stepmom gone bad

Stepmom's pacing the room with a worried look. You ask what's wrong. She startles. "Nothing, i'm ok, I think." She asks if you can stick around the house for the next few days. Make sure she does not leave the house. You're confused. She becomes more anxious. A growing look of desperation grows. Finally, she confesses. An hour earlier, her stupid friend played a joke & put something in her drink. A lot of female viagra pills. She knows exactly what these pills will do. Stepmom is a good woman, a good stepmom. Not a slutty whore. Who knows what these pills will make her do if she leaves the house! You calm her down. As stepmom begins to relax, there is an overwhelming yet pleasurable sensation between her legs. Her body arches. She holds on to the bed & grabs her crotch. No no no but yes yes yesssss. She fights it to no avail. But you, her stepson, can't see this! She needs to touch herself so bad! Her sexual desperation gets stronger. She moans & squirms. Good thing you're here...
