My wife had the hots for one of the neighborhood boys - the kid used to do yard work for us, Krista teased him mercilessly, I cock-blocked her, otherwise she'd have fucked him straight away. I constantly teased and tormented Krista about the idea of fucking him. When he turned 18, I arranged for him to fuck Krista. What the young man lacked in skills, he made up for with stamina, and the ability to give Krista buckets of cum.
The hottest part of that Saturday afternoon was helping the kid fuck her - I held his thick young cock, making slow circles on Krista's cunt lips and clit, using the head of his cock. The kid squirted his load as I held Krista's cunt lips back, exposing her clit, and using it like a little cock to fuck the guy's ...-hole.
Krista fucked the kid throughout the rest of the summer, until he headed off to college. She extended the fantasy realization with a "goodbye" gangbang including me, the kid, and five of his friends. I will never forget that summer or the experiences - especially seeing Krista ride that kid's cock, eyes rolled back in their sockets, screaming "Fuck me! Oh my fucking God, fuck me!"
