Caroll.

Tapping on your shoulder to get you to stop moving, Caroll climbs over your father's hips. You take his cock in your hand and guide her onto it. "Oh... thank you, Caroll," Paul lets out a pleased, throaty growl. "That's, that's much better. Still weird, but much better."

"Thanks Daddy," she smiles, before looking over her shoulder at you. "Now remember Alice, you want to get his prostate, which should be somewhere around here, I think." She leans over and points in the general area you need to aim for. "And make sure you get a nice rhythm going too. It is Daddy's first time after all."

"Do you want to do this?" you snap back, pointing at the strap-on. "Because we can switch right now if you want to. You know I have no problems with that." Caroll throws her hands up, says nothing and just plants herself squarely onto your father's hips. You stick your tongue out at her and start thrusting again, making both her and Paul moan as his cock twitches inside her when your hips bounce against his balls.

The bed creaks and the three of you grunt and groan together. Caroll has leaned back into you, and you two are kissing each other passionately while her hands busy themselves with her nipples and clit. Paul has rubbed his wrists raw by now and has resigned himself to watching his daughters pleasure themselves, and him, with his lower body. "Oh Caroll," he moans, "Your insides are so hot. Oh... you gotta get off me, sweetie. You two are gonna make me blow any second!"

You and your sister grin from ear to ear at him. You speed your exhausted hips while Caroll starts bouncing wildly on his cock. "Do it Daddy! Blow your load deep inside me!" She howls, while Paul tries his best to resist. Switching up your angles, you get a good shot at his prostate and **** him to cum.

He howls in frustration as his hot cum bastes your sister's insides, while she shakes and shivers in joy. "Oh yes! Oh yes! Oh yes!" she gasps, "I can feel it all inside me, Daddy. Ooh, you filled me all the way! You're such a good Daddy."
