“Get on all fours for me.”
Knowing what was coming, Holly obliged and got on her hands and knees with her ass pointed at Isaac. Wetting his hands with oil, Isaac started rubbing her first at her ankles, then the backs of her calves, then her thighs, wet with arousal, and at last he began massaging her ass the same way he had Donna’s, making Holly purr in happiness from the subtle yet focused sensual touching.
Unable to resist any longer, Isaac buried his face in her perfect ass, tongue-fucking her back door. Holly gagged and moaned in happiness, never quite able to get used to the sensation of getting sodomized by someone’s soft tongue. It always made her feel like she had just sat on an eel.
While Isaac licked her out, he rubbed her back with the oil and reached around to play with her breasts. In front of Holly, Alice was on all fours, moaning as Donna fucked her pussy with the strap-on in the doggy style position. Having learned early on how to use a strap-on, she was having no trouble thrusting into Alice’s tiny frame with brutal strength. However, unlike Isaac, she didn’t know she had to compensate for Alice’s build and limit the depth of her thrusts, so Alice was wincing and nearly crying out every time the dildo was pushed into her tight pussy. It was a good thing she was a masochist.
Donna loved using the strap-on, mainly because she liked to imagine all the calories she burned while thrusting, but also because she liked feeling that sense of dominance from time to time. Plus it made her feel sexy, as she watched her tits bounce and bob with the movements of her body.
Having had enough, Isaac sat up and hefted his erection, penetrating Holly’s wet pussy.
“Oh Master!” she cooed, feeling her bond with him reach its peak intensity as her body loosened to accommodate his manhood.
After holding still for a moment to enjoy to the heat, softness, and wetness of Holly’s perfect cunt, Isaac grasped her hips and began thrusting into her, his lap clapping against the back of her thighs. Now in the same position as Alice, Holly leaned forward and began to kiss the young girl, letting the two of them lick the insides of each others mouths while their pussies were hammered.
As always, Isaac remained vigilant, making sure they were out of sight and earshot of anyone who could be nearby. Having checked the beach through the breeze gaps in the sides of the tent, he allowed himself to relax and instead focused on pleasuring Holly. He increased the speed and power of his thrusts, even raising one leg to get better leverage. He hammered Holly with all of his strength, forcing her to break her kiss with Alice so that she could bury her face in the crook of her arm and whimper from the euphoric roughness of her Master’s thrusts.
“I’m going to cum!” Isaac panted after a few minutes.
“Please cum inside me, Master! Pour all of your semen in my pussy!” Holly begged.
Isaac granted her wish, and came to a sudden stop and shuddered as he released a load of his seed into Holly’s womb. At the same time, Alice cried out as she had an orgasm, telling Donna she could finally stop thrusting. The four of them collapsed, all gasping for air and exhausted, glistening with sweat and oil.
“Before we continue, how about we take a break and swim for a little bit?” Isaac offered.
His three pets all smiled. “Ok!”
Putting their swimsuits back on, the four of them all returned to the water, cooling off from fucking each other. They played a couple games while they swam, like Marco Polo and chicken. For chicken, Alice would climb up onto Donna’s shoulders and Holly onto Isaac’s, and the two young women would wrestle and try to push the other one over, while trying to resist looking at each other in their swimsuits. Alice was at a disadvantage, both because of her size, and because Holly’s bouncing breasts were a great distraction.
Marco Polo was played naked, with all the fun of the game with the kinkiness of reaching out and trying to fondle someone.
Immediately after leaving the water, the girls all applied fresh oil to themselves and went at it again. Like before, Isaac had Alice to himself, and was enjoying a long blowjob from his young slave. She worked his cock back and forth in her small mouth, slobbering all over it and massaging it with every soft corner. In front of Isaac, Holly and Donna had pulled out a new toy: a double-ended dildo, made of a sturdy yet pliable rubber, with a ribbed surface and an 18” length. They were both sucking on one of the heads while they touched each other, preparing for what they were going to do.
Unable to hold themselves back, the two women interlocked their legs and got into the same position as when they scissored each other the first time they had sex. Wet with their saliva, the thick rubber toy made them moan softly as they inserted it into their pussies. They whined as they pushed themselves together, forcing it into their bodies until at last they were pressed together, the lips of their cunts kissing around the dildo.
Grinding their hips, they began thrusting back and forth against each other, pulling back to expose the toy between them, then pushing together until their wet pussies kissed. Their moans were loud and shrill as they fucked themselves and each other with the toy, while unable to resist reaching out and fondling each other’s breasts. For Isaac, it was a truly unparalleled sight.
However, it was difficult to truly keep up the position, but both girls knew an even better way to use it. Pulling it out of themselves, they turned the toy around and both sucked it clean of each other’s juices, wishing they were sucking off their beloved Master. With the toy once again dripping with saliva, they both turned around with their backs to each other and got on all fours.
Taking a deep breath, they each inserted a head of the dildo into their asshole, then slowly leaned back until their asses were pressed together and the toy had disappeared in their rectal cavities. This was a new experience for the two of them, the combination of both sodomy and the erotic feel of having another woman’s ass pressed against their own.
Giggling to each other and knowing that it was their job to keep their Master entertained, they leaned forward and exposed the toy, then forced their asses back together, slamming it back into themselves. Moaning like opera singers, they began moving back and forth in perfect synchronicity, leaning forward and crashing back together, butt-fucking both themselves and each other.
Over and over again, their asses, glistening with oil, clapped together with glorious ripples, while their hanging breasts bounced and swung like pendulums. Sometimes one of them would clench down on the toy and hold it stationary, then slam themselves back against the other, similarly to fucking with a strap-on. They usually tried to keep it even between them and just let their asses slap together for their Master’s enjoyment while the toy was rammed inside them.
With the magnificent sight before him and Alice giving him an expert blowjob, Isaac ejaculated after only a few minutes, with Alice happily drinking every last glob of her Master’s seed.
