"I need to."

"Huh?" Courtney asked as she started moving a bit again. Then she felt her mother push her pubic mound into her ass...but she didn't feel any cloth covering it. Her mother's neat but full bush tickled Courtney's ass. "Wait...you...you want to masturbate on my ass?"

"Yes baby, I need to. If not I'm going to have to call your father to get his ass home so we can fuck like rabbits."

Courtney stared at her mother over her shoulder as she dropped down to the eight inch mark and stopped, "Oh...so full...but is that even possible? I mean...my ass isn't sticking out that much is it?"

Courtney felt her mother rub her ass as she spoke, "I'm not calling you fat, if that's what you're asking." Caitlin said, gently. "And no your ass isn't sticking out that much, which is why you have to clench it to make it stick out. But then you are concentrating on getting that monster in you, aren't you?"

"Ugh...yes. It feel so good mom. It really does..." Courtney said raising up again, then dropping down on her lover, reaching the eight and a half inch mark.

Caitlin slid a hand down her daughter's taut abdomen towards her full virginal pussy, cupping the mound. She started gently and rhythmically massaging her daughters clit with her fingers, "Little more baby. You can do it." Caitlin said encouragingly.

"Here goes." Courtney said raising up again, and instead of slowly taking him back in she just let her legs go and dropped down fast, to the hilt. "OH...oh shit...oh. I feel like I lost my virginity twice."

"Oh, shit...so tight. So good." Jeremy said, then pulled Courtney down to kiss her.

Caitlin smiled down as the two made out in front of her, her daughter impaled fully on Jeremy's dick. She chuckled to herself then got up off the bed and moved to her clothes. "There we go, have fun you two. I'll call your father, tell him our birthday lunch will be a little late. And for him to get his ass home to fuck me but good! And try not to cum inside of her Jeremy...she's ovulating right now."

The two took a pause from kissing and groping, "Okay, Caitlin. I'll try and hold out, but...this is amazing. I'm going to have to get a loan to get her a ring...if..you...you know..."

"Yes. But you don't have to get a loan...I can wait until you are the star Tight End on Da Bears."

"I prefer the Giants. But Da Bears would be good too."

Caitlin chuckled again as she got out her cell phone and left the room with her clothes.
