A new sensation

Kate was unable to just sit back and watch as Kate devoured her husband's cock, Jan was horny and needed to participate in the forbidden sexual experience happening in front of her. Kate exhaled at the touch to her bare ass, which had been pointed up in the air. It's been so long time since she'd had the warm touch of another to her skin. And she'd never felt the gentle touch of a female to her bare ass. While she knew it was so wrong, she couldn't stop herself because it also felt so good.

Kate paused with Rick's boner still halfway in her mouth as Jan's hand wandered around Kate's ass, touching and massaging her cheeks. Cautiously Kate began to resume her blowjob, unsure what her sister was up to. Then she felt hands run down her back, pushing her silk pajama top to her shoulders. The hands tickled back down her back and rested on her ass cheeks again with a slight squeeze. Jan had to standing directly behind Kate with the direction her hands were grabbing her pale butt. The view Jan must have at that moment flashed across Kate's mind. Surely Jan had a perfect view of her wet pussy in the moment because it was pointing in the same direction as the candle.

The soft hands traveled back up her back, letting Jan's fingernails scratch gently across her back in a relaxing sensation. This time as the hands reversed directions they slid down Kate's side until they came in contact with sides of her hanging tits. The arousal increased and Kate sucked down harder on the knob in her mouth. The fingers glided down the sides of her boobs until they found her erect areolas. Then the hands clamped down enclosing her breasts with both hands. Kate pushed Rick's dick deeper inside her throat until it pressed against the back of her head.

Jan's hands released the perky breasts and followed down to Kate's thighs. They then rotated around her hips and she felt Jan grab her plump ass again. This time Jan's thumbs ended up between her cheeks and when she squeezed she rotated her wrists, opening Kate's ass open and fully exposing her luscious pussy. Kate never stopped her so she let her right hand drift down between the opening and lightly touched Kate's exposed, soft slit. The touch sent an exhilarating shiver up Kate's body. Jan had never touched her sister that way before, but they had fallen into an almost dreamlike trance of sexual euphoria.

Kate sucked down even harder on Rick's thick cock and she cupped his balls in her hand. She started to make slurping sounds as she traveled up and down on his rock hard dick.

The sounds of the slurping and the moaning of her husband made Jan even hornier. She began to open Kate's wet slit as she spread her lips apart. Then she slowly inserted the tips of her middle finger into the soft, wet opening. The sensations sent Kate into a frenzy as she bobbed faster and harder on Rick's cock. Rick began to moan louder and pump his hips in reaction.

Jan was getting a kick out of the teasing she was causing Kate, knowing the ecstasy that was building inside her sister. Having not had sex for months would mean everything was growing stronger and stronger. She rubbed that soaking wet pussy, hoping to get Kate almost to the edge. She kept moving in a circular motions and then up and down, mashing and spreading her lady lips. Then she would enter every once in a while into her dark crevice to feel the moist inner parts of her sister.

Kate's erratic movements were increasing, cluing Jan into how close it was bringing her to the brink of a climax. She placed a second finger inside her sister's twat, moving her fingers inside and out with periodic pauses to rub up and down her labia. She had full control from this angle of Kate but didn't want to let her orgasm just yet as she knew the build up would drive her sister crazy, craving more.

That's when her kinky mind exploded with the most taboo thought of the night. Letting her sister suck her husband off was one thing, but would Kate be willing to be even more adventurous? Even more taboo to go as far as let Rick's hard dick enter into Kate's wet mound? The thought of it was growing into an almost uncontrollable beast inside her head. A craving that she couldn't ignore. She was the one in control here still and she needed to fill that craving by using her husband to make her sister have the greatest orgasm she'd ever felt.
