Fuck her harder

This is no inexperienced girl, you surmise. You aren't particularly experienced yourself, but the couple of girls you have fucked have all struggled at the start taking your size, this girl has taken you with no issues and is begging for it to be given harder. You try to get some traction on the pool floor with your feet, and attempt a piston like action. Of course you can only sustain this pace for a few seconds bursts.

"Oh God...yes... that's it," she moans opened mouthed, "fuck me with your big cock."

You continue your piston action, her pussy squeezing and pulling your foreskin. This is the first time in a year you have got some action, and it is overwhelming. The water and the ease at which you can enter her makes it a less sensitive pleasure than any time before, but the exhibitionist aspect makes your balls tighten up real hard.

You quickly glance around, and notice most of the people out of the pool are watching, in either amazement, shock or horniness. One of the couples in the pool is making out, certainly not fucking, so are not taking any attention away from you.

"Ugh...ugh...ugh..." you grunt as you continue to plunge your substantial length into her willing pussy. You balls floating up and gently hitting her ass with every push.

"Ugghhhhhhhhh..." she groans, gaining the attention of anyone who wasn't already watching "....I want you out of the water..." she breathes heavily into your ear.

This girl is some exhibitionist, you think. Too much for you, maybe.
