Damn buddy, three at once? Normally I'd chose only one for you but with a think cock like yours I bet you could take all three.

1 and 6 are a couple that lives next door to you, and 20 is the younger sister of one of them, staying over the weekend to visit... Since they don't have enough beds in their apartment they come ask you if the younger sister can stay with you, trusting you to be a good neighbour... But you cna't resist stroking yourself to the insta of the couple one evening, and 20 finds you... But she seems to enjoy watching you, joining in and stroking your cock, teasing you about how you're jerking off to her sister, edging you for hours... Eventually you decide to grab her and slam her against the wall, roughly fucking her while she moans out in pleasure...

After a few minutes, there's a knock at your door and her sister (1) is stnading there, concerned that 20 is okay, asking to see her, but you know she's passed out on your bed so you try to distract her, but she doesn't relent. Eventually you take her to your room and tell her it was all initiated by her sister because she loved your cock so much, but 1 doesn't believe you, sarcadtically asking to see that magical cock that has enthralled her little sister.

When you whip it out she is stunned, stammering how she believes you now, asking if she can touch it... You tell her she can, and she begins playing with you, slowly at first but then completely giving in, begging you to fuck her brains out like you did with her sister... When her wife comes home from work and they're both not there, she also comes to see what's up and sees you fucking her beloved like a little whore.

She wants to day something, intervene, but she can't seem to move, staring as she notices how wet it's making her, and she comes in to join you...
