Sexy Fun Times/Ten/Girl/School/Gramps/Fuck
Gramps pulls the waistband of his shorts down to reveal his cock. It's as stiff as a poker and you can see all the veins criss-crossing the shaft and the big purple head when he pulls his foreskin back. Amanda looks at it and then at you.
Without a word, she stands up, walks across the room and climbs up on Gramps' chair. She gets her knees either side of his thighs and just lowers herself down onto his stiff old cock. When she leans forward with her arms around his neck and kisses him, you have a perfect view of where her cunny is stretched around the shaft.
It's not long before he lets out a loud groan and you see his balls pumping their contents deep inside your friend's vagina. She keeps working and even though is cock is slowly going limp, she still manages to bring herself to a climax before climbing off. "Come over here," you say, and she sits back down beside you.
You drop to your knees, get between her thighs and suck your grandfather's spunk out of her cunny. It's a familiar taste as, for the last month, ever since Mr Smith taught you how, you have been swallowing it two or three times a week after school.
