Sharon!

"As much as I want to get fucked," Tory says, "And I really, real-ly do, I want to watch you fuck this whore even more."

While she says that, she reaches down and squeezes Sharon's big breasts, which are still slightly pressed against the table due to her position.

"Beg me for it," you say, looking at the fit redhead.
"Please fuck me, Master," Sharon says, abandoning all of her pride, "Make me cum on your dick like you did to my friend."
"More- beg me more!"
"Please, I need your big, hard dick," she says, "Fuck me hard. Fuck me so hard that I can't walk straight!!!"

You smile and nod in agreement. You pull out of Christine- smacking her on the ass as you do- and move towards Sharon, but you stop when an idea hits you.

"Since I'm fucking you next and since you've been such a good ****," you say, "I think you deserve a reward, Tory. How would you like 'Mom' here to lick you out?"
"I'd love it. Thank you, Master," Tory says, licking her lips, "I still get to watch you fuck this whore though, right?"
"Absolutely. I have just the way to make that work. Come over here and help me out for a minute."

She slides off of Sharon's taut back and moves over to you. She helps you untie Christine's legs from the table and turn her around. You bring her down to her knees and re-tie her ankles to the table legs.

Thanks to you two, Christine is now in position to lick Tory's cunt while the co-ed is facing towards Sharon to watch the show.

Both of you get in place now.

You untie the one end of her crotch rope, uncovering the whole hole for you.
You shove your dick into Sharon's cunt in one thrust, since her pussy is quite wet from cumming at Tory's hand...and tongue. She grunts as you enter her.

"Thank me for this dick," you order.
"Thank you for putting that big, hot dick in me," Sharon moans, "Fuck me, Master."
"I will. You're allowed to have my **** lick you out now, Tory."
"Thank you, Master," the busty brunette replies, grabbing Christine's hair, "Lick me, whore! Make me cum like I'm going to do to your daughter!"

You start to fuck Sharon now, as Tory begins to moan from Christine's licking. The room is full of sound now as Sharon grunts and moans in unison with Tory. This begs the question...
