Paul looked over at Diane who was slowly rubbing her clit. "Yes Paul, I saw you and I came the same time you did."
"Ohhhhhhhhhhh," Paul gasped as a small amount of cum leaked out of his swollen cock. "I have never seen two hotter women in my life!"
Cheryl turned up the machine a little higher. As she got used to the vibrations she looked up at Paul again.
"Did you see what I was looking at when I fucked myself with the big dildo, Paul?"
"Yeah, it was a picture of a man and a woman masturbating together."
"That's right, but what you don't know is one of the stories I was reading was about a mother and son who were having an affair. They were masturbating together for a long time till one day he just up and crawled on her and fucked her silly. That story really got me hot and looking at the picture made it even more intense for me." Cheryl gasped as a small orgasm overtook her.
Slowly she opened her eyes again. "I just came, Paul. Could you tell?"
"Yes," he hissed as he moved closer to her. "Cum again. I want to see you cum some more."
Cheryl reached over and turned the machine up high.
"OHHHHHHH! OH SHIT! OH MY GODDDDDD!" She shouted as her head dropped down and she leaned forward and supported herself on her hands as well as her knees.
Soft mewling sounds were now coming from her throat and tears were running down her cheeks.
"Better grab her shoulders, Paul. That is one long continuous orgasm she is having and she might fall off," Diane said as she leaned forward.
Paul moved closer and put both his hands on his mother's shoulders, steadying her as she writhed on the Sybian, impaled upon the maddeningly delicious rubber cock that was wiggling and vibrating against the walls of her vagina.
Diane and Paul watched in amazement as Cheryl's abdomen rippled like waves upon a beach.
"Shit Paul, she has the damn thing against her G-Spot!"
"Yesssssssssssssssssssssssssssssssss, oh FUCK ME!" Cheryl gasped.
While Paul was steadying his mother, Diane reached down and began to stroke his cock. She reached behind him and started playing with his ass, her finger getting ever closer to the sphincter. As she played with him she bent down and whispered in Cheryl's ear. "Suck his cock. Take his cock in your mouth and drain him."
Paul was concentrating on holding his mother while savoring the light fingers of Diane's ministrations. He wasn't fully aware of any changes until he felt his cock engulfed in warm wetness.
He looked down and saw that his mother had taken his cock into her mouth and appeared to be trying to swallow the whole thing.
"Yes, suck his cock. Make that boy CUM!" Diane hissed as she shoved three fingers in her dripping snatch.
Paul felt the warmth of his mother's mouth and the vibrations of her moaning and it was more than her could stand.
"Oh, FUCK YES! I'M CUMMING!" He shouted as his hips began to thrust against his mother's face.
Cheryl reached down and turned off the Sybian and concentrated on her son. She cupped his balls with one hand while squeezing the base of his cock with the other. She sucked like a vacuum cleaner, swallow all of his jism as he exploded within her.
As she felt him withdraw she fell back on the floor, legs spread as her hands squeezed her breasts. Her hips were thrusting upwards as if she was fucking the invisible man, still orgasming, her head lolled from side to side.
"Grrrrrr, I gotta do this," Paul mumbled as he moved between her thighs.
Still rigid with desire, he pushed his cock between her swollen lips. His cock slid easily into her waiting depths and as he bottomed out her legs wrapped tightly around him.
"Fuck me Paul, Fuck me," she cried softly.
Diane lay upon the floor next to them, her hands frantically rubbing and thrusting at her over-heated sex.
"Oh yeah..... God I LOVE to watch! Fuck her good, Paul!"
Their cries filled the room as they all crested over waves of incredible height and pleasure until exhausted; they collapsed and fell into a light but peaceful slumber.
Some hours later, after they had showered and eaten they all settled back and discussed the afternoon's activities.
"You still have that amateur movie you said gave you over an hour on the Sybian?" Paul asked Diane.
"Oh yes, it is in the VCR. You wanna watch it?"
"Yeah, I'd love to see it."
"I too would like to see what really gets you off, Diane," Cheryl enjoined.
"Ok, but on one condition. Paul fucks me first, Cheryl,"
Cheryl feigned a pout. "Ok, but I am gonna go get my new toys. That Sybian thing is too much for me. Besides, my knees are killing me!"
Diane laughed. "Yes, that is the one drawback. It is an awkward position to maintain for any time without your legs going to sleep. Took me almost a year to manage it."
"Well, I think I prefer to cum laying down, preferably in Paul's arms but that rabbit dildo will work just fine if he is unavailable." Cheryl smirked.
"You women are going to fuck me to death, but hell, this is every man's fantasy and perhaps I'll cum and go at the same time."
They all laughed at that then settled back to watch the flick, hands busy rubbing, stroking and just generally having a wonderful time.
