Anne & Therese's Sisterly Bondage

The twins knew that their plan would succeed, and now it had- they were both the slaves of the 2 boyfriends. No longer were Anne and Therese just the girlfriends of the men separately, but they were the shared property of both of them. After all, who could resist such an offer? The former, specific relationships no longer mattered. Anne did not care which was her original boyfriend, and neither did Therese. As for the guys, they simply had no way to tell them apart, anyway, other than their reactions to orgasm.

Orion awoke the next day, a Saturday, with an impressive erection, and had to relieve it, but before he could masturbate, he felt a tongue moving up his shaft, licking it for all it was worth. He looked down, and saw one of those gorgeous, auburn-haired twins using his cock for breakfast sausage. "Anne, or is it Therese?", he asked.

"Do you really care, mon cherie? We're both sexy, and we both like to please our men. We'll take such good care of you today, that you'll forget to even ask who's doing it. Besides, we're sisters, so we share everything!"

She resumed sucking his cock, and he felt ready to explode, so she just opened her mouth, squeezed one last time to trigger his ejaculation, and gulped it down like it was actual milk.

She started licking his balls, and then moving toward his ass, spreading the cheeks of it, and rimming it voraciously. Orion simply could not believe that he was getting his ass licked, and he did not not know who was doing it!

As for Harry, he was lying on the top of the covers, buck naked, when he was startled by warm, gentle, feminine hands, massaging their way up his body, taking advantage of his nudity to rub him down. He knew that one of the twins was doing this, but which one?

"Which one are you?"

"Ah, but mon ami, why spoil the suspense? Just let me pleasure you, and don't worry about who I am- after all, I am only a slave, right?"

He had no response to that, because she was already keeping him quiet with the gentle massage she performed on him. It was such a sensual experience, that he could not focus long on anything, but the extreme pleasure of her hands on his naked body. 

When he thought he might overcome by the feeling of the rubdown, she turned him over, and slid her pussy onto his face, after which she leaned over to suck his cock. The taste and smell of her sweet sex, so early in the morning, were like ambrosia or nectar to him, as he hungrily devoured her genitalia. She was busy, meanwhile, doing the same for him- she got him all hard and stiff as wood in a few minutes, and soon, he spilled his spunk into her esophagus, which clearly pleased her.

"Oh, my dear Harry, your cum is so delicious; I could swallow it all, but I want my sister to have her fair share. Besides, she shares Orion's with me."

He kept eating her for a while afterward, and then she suddenly got up, left the room, and one of them returned. Harry did not know whether she was the one who had just pleasured him, or the other one, but either way, she eagerly picked up where she or her sister had left.

Meanwhile, the same thing happened to Orion. His partner left, and then seemed to return, but did she? Soon, she was sucking and licking him just as hard as before, and then she mounted him, sliding her pussy along his cock until it was inside her.

"Don't worry, sir. I will do all of the work, and you can just relax."

He followed her suggestion, as she eagerly rode him, getting his cock stiffer than it had even been earlier. 

"Oh, mon cherie! Your cock is so magnificent- it's splendidly large and thick! It gives me such excitement- ahhhhh!"

That shriek was more than enough to make him cum, shooting his sperm into her cunt. 

While this happened, the other girl also positioned herself above her partner, this time it was Harry, and she rode him cowgirl-style. It was a clear collaboration between the pair to do all of the hard work, letting the men, whom they adored, relax from their stressful jobs.

It didn't take much for this horny Welshman to ejaculate, filling the woman with his semen. She lay on top on him, caressing his chest and shoulders a bit, and whispering her adoration for him in his left ear.

So exhausted, the guys dozed off a bit, and by this point, they had no inkling who was fucking them. The girls had gone to bed sooner that night, while the guys had discussed what to do with them. Now, the well-rested women were seizing the chance to make sure that the men would never figure out which girl was which. It was just more fun that way- they fucked someone, and they never knew the identity of their partners.

Both of the awoke to the sense that their cocks were contained in something, and as they adjusted to the light, they realized that they were lodged in the rectums of the women. The girls were taking their dicks in the ass, and greedily pumping them for cum. Sure enough, they had no choice, due to the anal stimulation, and they came in moments, sending plenty of cream between those buns.

Knowing the men to be exhausted, the girls did one last thing: they made out with each other. They ran from one room to the other, chasing each other, and whenever one would catch the other, the loser would have to eat the winner's pussy and ass. Soon, they were all drenched with girl-juice, dripping all over their sexy, naked flesh.
They kissed each other on the lips, tangling their tongues, and fingering each other's pussies and asses, after which they licked each other's digits. This was not the 1st time these girls engaged in lesbian incest, because, no matter which men they shagged, they always felt like staying lovers as well as sisters, for life.

This sight was enough to get the men hard again, and the girls simply gave them hand jobs, making them cum ASAP, and then they took that cum, spread it on each other's breasts, and licked it off, to the delight of the men, who fell asleep to the picture of the women locking lips again, as they cleaned the cum out of each other's mouths. It was a hell of a view, and the men never forgot it, despite all of their later adventures with the twins. These were "aggressive submissives", and they had proven it.
