A Breastfeeding Mother

The idea of them all climaxing together had her feeling weak in the knees. As if in a trace, Abby approached her mother, drawn to jiggling breasts like a moth to flame. Finally, standing next to her mom, she extended her hand in an attempt to catch one of the fleshy globes as it bounced back and forth.

Her eyes roamed her mother's naked body, which was starting to sweat from the incestuous sex. Then their eyes locked when mom looked at her, attempting to speak in between grunts and moans.

"Ugh! Abby... Oh God!... It's okay, sweetheart. Follow your... heart. We're under contract to... ohh... give honest results... go ahead, my love. Ray! Please don't stop!!"

Unable to hold back any longer, Abby bent down and grabbed one of her mother's sweaty tits. It was like an erotic game to capture the elusive nipple since mom's boob was in a constant state of motion. She took her time getting it between her lips, fearful of the sexual repercussion of taking things too far. After several hard sucks, a steady stream of milk gushed into her mouth.

She felt mom's body pulsating while her brother continued to fuck with abandon. Remarkably, Abby managed to nurse at a steady pace, giving mom continuous relief. Abby undid her own pants and dove deep into her underwear, finding her target. Round and round, her fingers circled her clitoris while becoming increasingly aroused.

Her mother was in the throes of ecstasy. It was a circle that would change their family forever. Sucking like her life depended on it, Abby devoured the breast milk while fingering her own pussy. Far from feeling uncomfortable, she reveled in the erotic moment. Their family bond had never felt so strong.

"I'm going to cum," Ray moaned.

Mom winced and tried to make a quick decision. "Do it... on my..."

"In your mother's vaginal canal," Dr. Kravchenko interjected. "I'd like to study the effects of mother/son insemination."

Looking at her mother's contorted face, Abby saw an internal conflict after having been blindsided by the doctor's request. Ray kept on thrusting, fucking mom deeply and without a hint of caution. She watched her brother focusing on the doctor's suggestion. Ray was positioned over their mother, thrusting with everything he had. When she heard her brother whimper, she knew he was already filling mom's pussy with hot cum.

And when she saw mom's toes curl on the stirrups, while her sweat covered body trembled, she knew mom was cumming at the exact same time. Abby sucked mom's nipple throughout the ferocious mom/son orgasm, which made mom cry from the overwhelming full-body stimulation.

While her mother climaxed from Ray's forceful fucking, Abby also succumbed to an orgasm of epic proportions from discreetly rubbing her own clit. It was like an incestual chain reaction had been triggered and it was mind-blowing.

Sensing the job was done, Abby gave a final suck and pulled her mouth away, licking the leftover milk that was left over on mom's nipple and using her hand to wipe her mouth clean. She saw her brother, who looked like he'd just finished a marathon, slowly pull his cock out. Ray's once engorged penis was spent, left dangling and soft. It was covered in a cum and squirt mixture and a trail of sex fluids connected Ray's cock to mom's pussy.

In the end, she saw her previously traditional mother laying there exhausted, covered in family juices. Sweat dripped from mom's pores and excess milk pooled between mom's chest. When mom let out a small moan, cum gushed from her vaginal canal and dripped onto the floor, courtesy of Ray's handiwork.

"Bravo," Dr. Kravchenko said. "My masterpiece."

"I'll never be the same again," mom said in a low voice, as if she had just been resurrected.

The doctor smiled, "Think of the contributions you've just made in the field of human sexuality."

It was true. Abby had read all of the documents that mom had been given regarding this experiment. Mom was a part of a game-changer and Abby was thrilled to be along for the ride. Looking at her brother's wet cock, she knew he agreed. Mom was still in a puddle of her own making. As a tight-knit family, all they could do was blush.

Not only were they part of a groundbreaking research program, their bond had become unbreakable. She watched their naked mother smile and hold her arms open, signaling for them to come closer and embrace. Abby was a young woman who loved giving hugs, so she tended to hug mom a lot more than Ray did. She was the first to hug their naked and sweaty mother, who laid on the medical bed with her feet still in the stirrups.

Nuzzling her face next to mom's, Abby didn't care that her clothes were getting wet from mom's milk and sweat. Ray came over and hugged mom on the other side.

When their mother puckered her lips, Abby was the first to plant a kiss. It was their first time kissing each other and it was tender. Mom turned her head and extended the same kiss to Ray, who accepted and kissed her back.

Mom stuck her tongue out and returned to Abby. They shared a wet tongue kiss, which was something that was never intended to be part of this clinical study. But there it was. Not wanting to be left out, Ray joined the sensual moment, sticking his tongue in between theirs.

The three-way kiss was loud and sloppy, filling the lab with lewd sounds. Abby was positive she heard Dr. Kravchenko masturbating in the background, but her attention was focused on her mother and brother as they enjoyed the benefits of a loving family.
