Horse In The Pool

MY daughter and I were playing with my granddaughter in the pool. We were playing "horse" with the pool noodle. Granddaughter and her mom straddled horse and tried to "ride" around the pool. Finally I joined on so all three of us were on the noodle, barely keeping heads above water. I was in back, daughter in the middle, granddaughter up front.

With my daughter's little ass rubbing against my groin I soon got a hard-on my daughter could feel poking her in the butt. She pushed her butt out so that her crotch was directly on top of my erection. We continued that way for a minute or so.

Without asking her, I took a hand and placed it on her lower belly, just above her bikini bottoms. I took a deep breath with the last shred of common sense I had, then I pushed my hand inside her bikini bottoms and went directly for her clit. As soon as I made contact she pushed her crotch hard on my finger and ground on my erection. I played with her a minute or so like this then went for it as stuck a finger up her pussy and flat out fingered her.

I made my daughter cum in the pool several times as we continued to "ride" around the pool on the noodle. MY granddaughter was laughing and giggling the whole time while my daughter seemed lost in the fingering I was giving her, periodically arching her back and cumming on my finger.

We didn't speak about it but the next time she and my granddaughter come over to swim without my son-in-law, I'll see if they want to play "ride the horse" in the pool again!
