The twin sisters looked into each other's eyes, their faces inches apart, and cried out their moans. They were both on all fours on the floor of their shared bedroom, naked and sweaty, calling out their pleasure as their boyfriends fucked them from behind.
The twins Chrystie and Jess had been experimenting for years. Fascinated by each others' bodies and drawn to each other purely from the taboo of their relationship. Not that they ever did anything directly to each other. They wanted to, they desperately wanted to feel their naked forms pressed together, rocking and licking and rubbing each other to ecstatic orgasm. They had often said as much when masturbating together.
But they had their rule, their one rule. No touching in an intimate manner or kissing or fucking. They were determined never to cross that line.
So naturally, this is the story of how they finally crossed that line.
Each girl moaned as the fucking continued, their boyfriends' hands gripping their hips tight as they thrust faster and faster, their cocks buried deep within the two women. Both Chrystie and Jess called out their pleasure, rocking their own bodies back and forward against the hips of the men, clenching their thighs over the meaty tools of pleasure and demanded more.
"I want you so bad!" Jess cried out, "please give it to me!" her voice barely audible through her own desperate pleasure.
"I need it, I need it from you. You could fuck me so hard!" Chrystie said, seemingly to the man whose cock was buried so deep inside of her.
But neither of the men realized that the twins were speaking directly to each other, eyes locked and faces so close they could have kissed as they told each other just how desperately they wanted it. How much they wanted that incestuous relationship that was so close within their reach. And it was the taboo of secretly admitting that directly in front of their boyfriends that finally brought the twins to orgasm, bodies shivering and shaking as they came, their moans turning to hollers and yells.
The two men, assured that their women had cum, were finally able to stop holding back their own relief, exploding into the condoms they wore before collapsing on top of their girlfriends.
