[MFF] [incest] “Can I watch?”

Tom had enlisted in the military not a year ago, and in keeping with the traditions of the Army, he had bought a car he couldn’t afford and married a girl out of his league.

Sara, age 22, was as beautiful as they come, a stereotypical All American beauty queen. Tall, blonde, eyes as blue as ice, curves that begged for motherhood, and a skin so pale you could swear any sun exposure would prove fatal.

Her sister, 19-year-old Francine, was as much her polar opposite as herself breathtakingly beautiful in her own way: dark curly hair, eyes the color of coal, surrounded by a dark complexion all year long, and a petite frame perfectly befitting of her A cups.

In Sara, Tom had everything a man could want: beauty, smarts, ambition and an insatiable sex drive. And yet, sometimes he had found himself fantasizing about Francine, wondering “what if”, and then – after it all – he had washed away his shame in the same napkin that held his cum. He would have never admitted to it, of course. A few moments of weakness is all.

As he walked into his in-laws’ house, he had no idea it would all be different in a weekend. They, Sara’s parents, they would be out of town for a few days, enjoying a cruise in Mexico. “Take care of Francine” they said before entrusting the young groom with the man of the house hat for a week.

In fairness, for the first evening, he did a good enough job. But then he couldn’t wait to be alone with his young wife, and as they made their way to the bedroom, they told Francine not to get in trouble and left it at that. She could have left the house, taken the car, drove off to Canada, vanished never to return. Instead she chose to find her way to dad’s liquor cabinet and pour herself the finest scotch that she recognized the name of. One. Two. Three shots.

Meanwhile, upstairs, behind a closed door, on a warm comfy bed, Tom was lost between Sara’s legs. His tongue flicking her clit, drawing the alphabet. His hands caressing her thighs, helping himself keep a close grip on her, not wanting to lose a drop of her taste. Sara’s eyes closed, her body writhing, her moans loud, begging for more, “don’t stop baby don’t stop”.

When the door opened they didn’t even hear it. When Francine first spoke, they didn’t even hear her. She had to almost scream to get her point across. “That looks hot. Can I watch?” she said.

Tom was startled, he turned around, almost broke his neck in the process. Sara jumped on the bed, “what the fuck?”. Was it the booze talking? Suffice it to say that, while Francine’s heart pounded with fear and lust, her voice sounded almost steady, confident. “I said I want to watch” she repeated.

Often, in life there’s a turning point, one where the right choice could be made, and it would be a non-event. Or the wrong choice could be made, and it turns into a story for the ages. This was that turning point. They could have noticed Francine was drunk, pushed her off to bed. But instead, Sara broke the silence. “You can’t tell anyone, ok?”
“Deal”, answered Francine, a bit too quickly and eagerly, like she hadn’t even seriously pondered it.
“Not even…” started Sara
“Not even the girls at work, I know, I know. I won’t tell. Promise.”

Tom. Tom hadn’t said a single word. He looked dumbfounded, to his wife, to his sister in law. Was he truly to continue tongue fucking his wife as her own sister watched? Apparently so, for Sara grabbed his head back and shoved it between her own legs again. “Go baby” she moaned softly.

If he had any reservations, the intoxicating, sexual, primal, animalistic scent of his wife’s arousal, it canceled every ounce of judgement. He was back at his station, serving duty. He started licking again. Sara moaned, begged, all the while her eyes focused on Francine. She was putting on quite the show.

Not to be outdone, Francine slipped out of her own panties, leaned back against the wall, spread her legs and started fucking herself. One finger rubbing her clit, then two fingers inside of her, slow, teasing herself. The two sisters stared at each other.

All Tom saw was a shadow. And when he looked up, Sara and Francine were kissing. Making out like two schoolgirls. He had watched porn to this effect, but.. but real life was different. In the movies, the guy knew exactly where to be, what to do. But Tom, he had no idea. Was he supposed to continue licking his wife’s pussy? Was he even allowed to touch Francine? Acknowledge her? His brain was spinning, trying to ponder the right thing to do. But, once again, it was decided for him.

“What does it feel like? When he licks you” Francine asked voluptuously.
“It feels like heaven” moaned Sara, before turning to Tom. “Lick her” she commanded.

Tom paused for a second. Was it a test? Was he supposed to say no? And then his brain gave way, and his tongue found its way between his sister in law’s legs. She tasted just as sweet as Sara, he thought to himself as his tongue found her clit and started licking her juices. Francine’s legs clasped tight, her eyes opened wide, her mouth agape, she gasped, as if she wasn’t expecting anything could feel that good.

It took but a few strokes of the tongue for her young petite body to tense up as she came. Sara was licking her nipples, Tom was fucking her with his tongue. It was too much for Francine. She exploded in orgasm, saw stars, saw lights, and then panting, sweating, laid on the bed, on top of her sister’s naked body.

When she regained control of her body, she jumped on Tom, and kissed him. Kissed him with a passion she didn’t know she had. He reciprocated her mouth. He reciprocated her tongue. Let his hands cup her petite tits, and he felt his hard cock try to find its way between her legs. He knew he couldn’t. And yet his cock didn’t obey his will, it only obeyed biology’s imperative.

Sara knew. “Do it Tom. Fuck her” she egged him on. And the last obstacle out of his way, he did. He penetrated Francine. He started pounding her, rhythmically, slow and steady, his pace increasing gently at each stroke.

Francine’s hips reciprocated his every move, as if on autopilot. She didn’t know where she had learned this dance, but she danced it to perfection. Her pussy tight around Tom’s dick, her body like putty in his hands. She moaned even louder than her sister. Now it was Sara’s turn to watch and fuck herself. And it was Francine’s turn to get lost in the pleasure, the sensations. Everything was new to her. She didn’t even know how her body could feel. And Tom was giving her wave after wave of pleasure.

Sara took her fingers out of her pussy, grabbed Francine’s hair, pulled back, and bit her neck, before letting her sister taste her juices. Francine licked them, moaned, and then went to kiss Tom.

That was more than Tom could bear. He pulled out of Francine just in time, the first spurt of cum rushing out of him just as the tip of his dick left his sister in law’s fertile pussy.

“Did you want to cum in her?”, asked Sara after a few minutes of silence, as they all laid naked next to each other in the bed
“Yes”, admitted Tom
“I wanted it too, you know?” said Sara. “And you, Francine?”
“I..I don’t know” she stuttered. “I am not on the pill” she said, before thinking about it a bit, and then adding “Yes, yes I think I wanted it”
“Maybe tomorrow” was Sara’s answer, before they all fell asleep
