Incest Sister-in-Law Helps Out

[neerathemall]

"Mind if I join you?" His thoughts are interrupted as Rhonda steps out on the balcony and lights a cigarette. Tim moves his leg, so his sister-in-law doesn't see the bulge in his pants as they stand beside each other gazing out over the balcony, enjoying the peace and quiet.

"Not at all," he smiles.

"As hung up as they are about anything sexual, it's a wonder they ever had kids," Rhonda says, taking a drag on her cigarette and blowing the smoke out over the railing.

"I know what you mean," he laughs. "I just wish they hadn't instilled so many of their hang ups in their kids," he adds, without meaning to disclose so much.

"You too?" she asks, raising her eyebrows.

"You know, I just meant," he stutters. What did he mean?

"It's okay." She touches his arm. "I understand. Paul's a wonderful man and he treats him like a princess, but sometimes..." Her voice trails off as she shrugs and stamps out her cigarette.

"We'd better get back," she says.

Tim watches her ass sway inside her skirt as she walks ahead of him into the house. He's never thought of his sister-in-law sexually before, but he swears she's adding a little extra swish to her walk today. So her sex life isn't any more exciting than his. Interesting.

Sharon and Tim had long ago fallen into a routine of having their monthly sex after the dinner party at her parent's house. It is perfunctory sex, with no foreplay and no variety. Sharon goes into the bathroom, brushes her teeth and lubricates herself, from a tube. He's already in bed naked, when she crawls under the covers before removing her nightgown. She lies on her back and spreads her legs as he positions himself over her.

With erotic thoughts of his sister-in-law making him hard, he penetrates his wife's artificially lubricated pussy. As always, he's gentle and loving, still hoping for a reaction that never happens. As he feels her warmth envelope him, he mechanically pumps in and out while visualizing the sway of his sister-in-law's firm ass. He has a momentary flash of Rhonda's face, contorted in ecstasy, and her voice urging him to fuck her harder.

"Come on, Tim!" he hears her moan. "Fuck a woman like she needs to be fucked!" He complies with her wishes, slamming his hard cock into his wife's pussy while visualizing his sister-in-law lying under him. He vaguely hears his wife's surprised gasp as his body's urgency takes over and he drives his cock deep into her unsuspecting pussy.

He rocks faster, his chest pressed into his wife's tits and he can't help but think about Rhonda, wondering what her nipples would feel like rubbing against him. He envisions her face and lowers his mouth towards her moist lips. Before he can complete the kiss, his cock explodes, bringing him back to reality. As his hot cum spews into his wife's pussy, he notices the confused look on her face.

"I love you," he whispers as he kisses her tenderly on the lips, before disengaging his spent cock and rolling off of her.

"I love you, too," she sighs as she gets up and goes to the bathroom to shower away any evidence that they actually had sex. This is part of the ritual too, but tonight she forgets to put her nightgown back on and he is treated to the sight of her naked body as she hurries into the bathroom. His cock starts recovering immediately as he wonders how Rhonda's body compares to his wife's. Rhonda is about two years younger and from what he has seen has a killer body. He falls asleep dreaming of his sister-in-law.
