Wife asked me to imagine the youngster by pool while we fucked

Last summer our family vacationed at a condo in Florida.
We were at the pool when a heavy-set lady and her daughter came down to the pool.
This condo gets lots of guests from Europe. I'm pretty sure these two were speaking Russian.
The young girl walks to her lounge chair and unzipped her short-shorts. She tugs them down and bends to put them on her chair.
The kid, about 5'5", is wearing a beige (almost flesh-colored) one-piece suit with a thong back.
That suit is splitting her incredibly shapely and very pale ass, cut way up on her lovely bare hips!!, and the clingy top is displaying the hard nipples on her small, firm breasts.
It is nearly impossible not to watch her walk around! Her butt cheeks move just a fraction as she walks - not too big or flabby - just the size to make a very nice handful for a man.
The damn kid would not stay in the water! She was constantly diving in, climbing the ladder with a massive wet up-butt wedgie,....fixing her top over her breasts which keep try to escape, jogging around the pool to the board again!
My wife was watching me closely - so closely - with an amused look on her face!
How old was this sexy kid? ....I've no idea - I hope she was 18. But if she was 3 or 4 or 5 yrs younger than that it would not surprise me. This kid could have been the poster child for "Jail Bait"!
I moved my towel to my lap, and tried to read my book. My wife just sat, chin on her palm, smiling and watching me try so hard not to glance at that bare bottom! (she knows I am a devoted "Bottom Man"!)
That night we had a few too many drinks at dinner. Back in our room she pushed me against the wall - and started undressing me. Then she had me sit on the bed and watch her slowly undress. Then she straddled me, sitting in my lap - her pussy open, smelling like sex, and very close to my erection.....and she asked, "did you enjoy that little cunt's cute bottom, today? I think you did!. Now I want you to think about having that kids' butt in your hands, squeezing and kneading her until she cries out - while slide you up into me. Think about how tight she would be - and how you could still taste the pool water in her young pussy!"

'Honey! Honest - I tried not to look at that kid! I really did. But damn...! she was so sexy and so innocent...all at the same time! And what a butt that kid had! OMG!
I said, "Honey - imagine if that was a young - hunky, well-built kid in a super small little Speedo suit. Imagine if you could clearly see the shaft of his young dick and the size of his young balls all nested in his crotch! You'd have looked! You'd have gotten wet!.....OK, yeah, that little Soviet pussy made me hard as hell! She was like a walking 'wet dream'!" She got quiet - imagining that young stud with his thick dick and balls stuffed in that tight little Speedo.... Then she dropped HER tight little cunt on my happy dick!
"You imagine her - I'll see what I can come up with in my head!"
Wow, we fucked each other hard that night! That little Russian cunt's buttocks were something to see!
