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 tastes different, mixed with Amanda's juices and you swallow as much as you can. Ever since Mr Smith taught you how, you have been swallowing his two or three times a week after school and he told you that it's got loads of vitamins and stuff.

Gramps always takes ages to recover after a fuck and even watching you with Amanda isn't enough to get him hard. You go over and put some music on and you both start dancing around and doing a strip tease for him. You both undo your shirt buttons one by one to reveal your budding little tits. Amanda's are bigger than yours and she puts her hands under them to push them out.

You both end up in just panties and white socks and you can see Gramps' cock is beginning to react. Working together, you both hook your thumbs into the elastic waistbands of your panties and slowly wriggle them down over your bottoms.
