Licking his lips, Isaac reached Donna’s ass and gripped both her cheeks tightly, but he was barely able to get their mass into his hands. He moved back and forth, squeezing them and then letting them slip out of his grasp, smacking the oiled cheeks and relishing the beautiful sound. He soaked her smooth white skin with oil, making it glisten in the sun. Donna hummed from the massage, glad to have met someone who truly appreciated her figure. He then spread her ass cheeks, exposing her asshole and pussy, just waiting to be penetrated.
Isaac hefted his manhood and lathered it with oil, then began to rub it between her ass cheeks like a hotdog in a bun. The oil let him move against her so easily, it was like grinding between two mountains of butter. He slowly and smoothly teased her with his cock, prodding her back door with the head and then instead rubbing the shaft with it.
“Master, please fuck me!” Donna whispered.
“What was that?”
“Please, Master, fuck me in the ass.”
“Good girl,” he chuckled, kissing her behind the ear.
Sitting back up, he once again spread her ass cheeks and pressed his cock against her asshole. Slippery with oil, it entered her effortlessly. Donna groaned as he forced his member inside her, stretching her asshole to its limit. No matter how much punishment she endured, she still couldn’t get use to the size of him inside her. Lying down on top of her, Isaac gripped her by the shoulders and began thrusting into her.
Each time he entered her completely, Donna grunted in a mix of pleasure and pain, relishing the sensation of her Master dominating her and using her. He pulled her hair, adding to the intensity of her sodomy as he used her asshole as a punching bag for his cock.
Ever since becoming Isaac’s slaves, Holly and Alice had been trying to teach her how to be a masochist. The lessons weren’t being taken nearly as well as with Alice, but at least now she enjoyed being abused and brutalized by Isaac. But of course, Isaac only did those things because she enjoyed them.
Periodically stopping to scan the beach through holes in the sides of the tent, Holly watched Isaac fuck Donna with the inability to stop from touching herself. She loved watching Isaac fuck other girls, it made her feel like just a sex toy for him. Whenever she watched, she fantasized about him pulling out of the other girl, grabbing Holly, and forcing himself inside her with his manhood still slick with the juices of the last girl.
Alice was the same, stroking her tiny pussy as he watched Isaac sodomize Donna like an animal. It was interesting for her to watch how Holly and Donna looked when Isaac fucked them, and how they reacted. She would try to imagine how she would react in comparison and picture herself getting fucked instead, watching it as if in an out-of-body experience.
Isaac’s hold on Donna suddenly tightened and he stopped his thrusts, telling Donna he had just ejaculated into her. Already she could feel the hot fluid being pumped into her ass, and having become his slave, she loved the sensation. Isaac pulled out of her, a string of semen stretching between his cock and her gaping asshole.
“Ok, girls, time for you to entertain your Master. Take out some of the toys we brought,” Isaac ordered while Donna sucked him clean.
Reaching into the cooler, beneath the food and drinks, Holly pulled out the strap-on she often used on Holly. With a wide smile on her face, she secured herself in the harness while Donna rolled onto her back and spread her legs. Sitting in his beach chair like a king on his throne, Isaac prepared to watch them when Alice crawled over to him.
“Master, could you do that to me? What you did with Donna’s swimsuit?”
“Sure thing, honey,” he replied, letting her settle in his lap with his erect member between her legs.
Beginning to kiss her behind the ear, he reached around and ran his fingers back and forth against her covered slit, feeling the cute lips behind the fabric and teasing Alice. Gingerly, he worked the crotch of the swimsuit into a narrower and narrower strip between her skinny legs, bunching it up until it had formed a rope nestled in her camel toe.
Now ready, he grasped the front of her swimsuit and roughly pulled it upwards, tightening the fabric against her pussy. Alice whimpered as it grinded against her sensitive lips, feeling like she was being flossed from below. Her face turning red with horniness, she released a shrill whine as Isaac yanked her swimsuit down from her shoulders and exposed her flat childlike breasts. With one hand pulling her swimsuit against her pussy over and over again in rough jerks, Isaac used his other hand to pinch Alice’s pink nipples, making her yelp in pain and then pleasure.
While this was going on, Holly was thrusting into Donna with the strap-on, making the grown woman moan in happiness. Donna was on her back with her legs wrapped around Holly, who was on top of her while using her arms to try and hold herself up. She loved watching Donna’s breasts jump every time she forced the dildo deep into her snatch, and she loved even more the sensation of their nipples kissing when she leaned over to French her.
After a few minutes of Donna experiencing Holly’s Masterful skill of the sex toy, they switched, with Donna getting a turn in the harness. She stayed on her back, letting Holly ride the standing dildo. Bouncing up and down on Donna’s lap, Holly giggled and licked her lips as he played with the woman’s breasts, batting them around like a kitten with a ball of yarn.
While this was going on, Isaac had pulled aside the crotch of Alice’s swimsuit, exposing her glistening pink slit. He had long since penetrated her, and she was riding him much like Holly was riding Donna. With the underage girl whimpering and whining as she straddled him, Isaac constantly scanned the beach, turning his head like an owl to make sure that nobody was around to hear or see the four of them. Sex in a public place was one thing, but sex with a seriously illegal girl, that was something else all together, and they had never done anything like this outside the apartment. This was risky to say the least.
Isaac watched with a smile as Holly’s bobbing on the dildo suddenly picked up in speed and intensity, and the gentle hum she was releasing turned into a shrill whine. Knowing what was coming, Donna couldn’t resist reaching up and tugging on Holly’s nipples, providing that last-needed stimulation to trigger a gushing orgasm, soaking Donna in her arousal. Moaning in joy, she collapsed on top of Donna, before slowly pushing herself up and kissing her. Dismounting the dildo, she eagerly turned around and began sucking it clean.
“That reminds me, Holly, I forgot to apply suntan oil to your back. Alice, how about you play with Donna for a little bit?”
Alice sighed and smiled, having wanted to enjoy riding her Master for a little longer, but always happy to play with Donna. Alice removed her swimsuit and crawled over to Donna, with Holly retrieving the bottle of suntan lotion and crawling over to Isaac.
