You're spending the night at Granny's house. To your embarrassment, your step-mom has told her that you've been having nocturnal emissions! Granny insists that you masturbate in front of her before bed so you don't have a wet dream and dirty the bedsheets. You're very reluctant, but Granny tells you this is non-negotiable. Realizing that you need some visual stimulation, Granny lifts up her nightgown to show you her boobs. She gives you some topless jerk off instructions for a few minutes, but then you get bold and ask to see her pussy! Granny is surprised, but she kindly complies. At your further request, she even starts to finger herself. Now Granny gets really into it, and the two of you enjoy a gentle mutual masturbation session together ending with a cum countdown and a simultaneous bedtime orgasm with Granny.
