Since they were no longer worried about being heard, the young couple began to move more and did not bother to keep their gasps and moans quiet any longer.
Climbing on to David's narrow bed Theresa knelt next to the copulating incestuous couple.
David took one hand from his sister's throat and carresed his mother's face and then turned her face towards his sister's so they could kiss. The obscene tableau excited her past any point of holding back. She and her daughter french kissed like long time lovers.
Her son let go of her face and boldly slid his hand down to his mother's heaving chest to palm her nipples and squeeze her breast. Julie went into a frenzy as she came from the stimulation.
David slipt his hand between his mothers legs. The back of his fingers rubbing at her bare pussy lips.
Theresa moved one of Julie's hands to her own breast and began pinching her daughters nipple.
"Harder mommy, make it hurt I am getting addicted to the pain."
David felt his mother spread her legs more so he could slip 2 fingers into her dripping gash. Curling his fingers he felt for the lump inside that he had read about called the G spot.
Theresa wondered how the Hell her young son knew his way around a woman's pussy so well as he pushed her to orgasm in less than 30 seconds.
She put her other hand on Julie's back and slid her hand down to her tiny ass. Humping at her son's hand and devouring her daughters mouth.
Theresa teased the little girls puckered asshole, before feeling where her son's cock was stretching the girls pussy tight.
Lightly cupping Davis balls she lubed up her finger with the mix of girl and boy cum and used it to lube the tiny pixies asshole.
Julie became even more frantic as her mother pushed her ring finger up the girl's tight anus. Julie's eyes rolled back in her head as she came harder than she had before in her life.
Her brother clamped his hand right around her throat and her mother pinched her nipple as hard as she could. The little girl passed out cold and her two lovers lowered her to her side next to her brother. His cock came out of her tight hole with a wet pop. Theresa gently removed her finger from the teen girls anus.
David let go of her as well and moved his now free hand to his mothers perfect hanging tit. She smiled and said "Easy big guy, I don't like it as rough as this little masochist."
He moved his thumb on the hand in her pussy and rubbed her clit while fingering her.
"Oh that's lovely. "she moaned.
After enjoying that for a bit she moved slightly and bent to take his rigid cock into her mouth. The delicious taste of the mix of both her children's sexual fluids was heaven.
Squeezing his cock at the base she pushed the foreskin back and exposed the head of his penis And ran her tongue around the base of the crown.
No longer willing to wait she took the cock out of her mouth.
" David can I take her place on top?"
" God mom I thought you would never ask."
Swinging a leg over him, she stood with a foot on either side of hips. Squatting down, she guided his long thin dick into her hairless slit.
Her son held up his hands and she held them for balance. Flexing her hips she began to grind on a real prick for the first time in more than a year.
David was surprised and pleased by the pressure from the buttplug in his mom's ass. The smooth ball shape rubbing hard on the underside of his cock. It was like a milking machine trying to push all the blood to the head of his penis.
Julie began to come to from being unceremoniously bounced about.
"Oh mommy, you are so sexy,'' she said, she put her head on her brothers chest facing up and captured her mother's right nipple in her mouth.
Julie worked her thin arm down between the two lovers so that she could rub her mothers clit and play with her gold ring.
Even though David had cum 3 times today this was a lot of stimulus, he said " I can't hold out much longer" through clenched teeth.
Julie redoubled her efforts on her mothers clit and Theresa, for her part concentrated on her rapidly approaching orgasm.
"Should I cum inside?" David gasped.
"Yes!" his mother said "Fill me up baby,you can always cum inside mommy if you want! Here I cum!!" she shouted.
David gave up trying to hold back as his mother's pussy convulsed around his spurting cock. His young dick spraying potent semen into her mature womb.
Theresa collapsed next to her son her back in a bit legs sprawled.
Julie pounced on her mother, clamping her mouth on her mothers clit, the ring clicking on her teeth. The salty taste of her brothers semen and her mom's rich deep musk was mana from heaven. Her mother was helpless and began to thrash from another blistering orgasm.
David was exhausted and laying flat gasping for air and could not remember a time he felt more loved.
Julie put her fingers together on her tiny hand and pushed all of them into her mom's well stretched and lubed pussy. Her tiny fist fit, but just barely. The pressure made her mother cum again and the little girl could feel the bones in her hand creek like it was being crushed. As the spasm faded she used the tip of her small finger to try and force some of her brothers cum past the cervical head.
