Heads to the Hot Tub

Kayla hops over to you as soon as the girls disappear upstairs. She plants herself on your lap and begins to make out with you fiercely and grind her pussy against your erection.
"I'm getting so impatient, James..." she pants into your ear, then resumes her sloppy kissing. You grab her ass with both hands, squeezing tight, then you smack her cheek hard.
"Off...she's not gone just yet." You toss her playfully onto the couch as you stand up. She eyes you with lust, pulling her top down to expose her big tits.
"Can't you just feel them... around your cock already, James?"
"shh...." you put a finger to her lips, but she just sticks it in her mouth, sucking lewdly.
"Alright... I'm going to hit that jacuzzi and have a little more wine..." she sways off, winking before exiting the sliding door.
You sit down hard, panting for breath and trying to slow your heart rate. You still aren't 100% sure you can do this.
