Suddenly it struck her, exactly what it was about this situation that was causing so much déjà vu for Violet. Kath had-!
Violet started and smacked the back of her head against the bottom of the table. Wincing, she crab walked out from underneath and placed the figurine back on the table where she found it, and looked her sister in the eye in deep surprise. Kathleen looked back, not quite pulling off the innocent expression.
“You- You have-“
Kathleen sighed. “You saw it?”
Violet nodded.
The innocence left Kathleen’s face, and she bit her lower lip with mischief.
“Yeah, I saved the book. I haven’t used it until today, but I’ve read what I could about it.”
Violet took a deep breath, vividly remembering things that happened those few years ago. A bit of dampness stole into her pussy. She leaned in her chair as though to get a better look at the bedroom.
“You don’t have a girl tied up back there do you?”
Kathleen laughed, “No, I was just feeling a little horny, and decided to grow a dick to masturbate with. Why didn’t you tell me how much fun it was to play with these things?”
She shifted in her chair again, “Or how uncomfortable it is to hide it.”
As Violet watched, Kathleen got up, the front of her skirt being pushed out by something long and semi-hard. She walked back and forth a bit, watching her crotch area.
“Makes you wonder how boys keep these hidden in a pair of jeans.”
Violet laughed at that, her eyes never having left the now-obvious bulge at her sister’s crotch. Kathleen paused. “Do you want to see it?”
Violet opened her mouth to decline, but as she did really want to see her sister’s new genitals, she nodded instead.
Kath slowly reached down and pulled the hem of her skirt up, deliberately giving her younger sister a show. Violet felt her heart rate rise as she saw the monster protruding from between Kath’s legs. It looked so foreign, a woman’s body with smooth supple skin everywhere, except for this darker member hanging in front of a sack of testicles. But for some reason, that made it very very arousing.
Violet took another deep breath, trying to calm herself, as there was far too much moisture downstairs. With one hand, Kathleen reached down and stroked the beast, her other hand sneaking up under the hem of her own shirt and grasping her tit. Despite herself, Violet stared at the muscular cock as its skin moved in sympathy with Kathleen’s hand, remembering how her own cock had felt in her own hand all those years ago.
She got up suddenly, conviction entering her mind. She stepped close to her sister, staring into her eyes. “Kath. Let’s do it again.”
A grin slowly spread across Kathleen’s face, and she pulled her sister into a slow kiss, her member pinned between their stomachs. When they broke, Violet’s hand found Kath’s penis, and led her to a chair, and bade her sit down.
“I’ve tasted you before, but now that you have different juices, I want to taste you again.”
Kathleen sighed and stroked her sister’s hair.
Lifting the skirt out of the way, Violet dove on the dick, only taking a couple inches at a time into her mouth, using her hand on the rest of the shaft.
Kathleen gasped at the sensation of a wet mouth on the head of her cock. It was unlike anything she had ever felt while still having a vagina. For the next minute or so, there was little noise but wet sucking sounds, and little to see but Violet’s head bobbing up and down.
With all of Kathleen’s experience of sucking dick, she figured that she would be here a little while yet, as every guy she had ever blown took forever to orgasm when she used her mouth, if ever. But when the pleasure rose unexpectedly after only a minute, Kathleen sucked in her breath and held it, sitting up in the chair in surprise. She let out a little whimper as the first jet of semen shot into Violet’s mouth, and another with the second, pleasure filling her mind with stars.
Violet grunted as her sister’s cock exploded into her mouth, but she managed to swallow every bit of semen as it leaked into her mouth. She pulled the cock out of her mouth with a pop and mock-glared at her sister’s shocked face.
“A little different than a regular orgasm, yes?”
Between heavy breaths, Kathleen nodded. She swiped her hair out of her face and apologized to Violet. “I never realized it would be so intense! Or that I would cum so quickly!”
Grinning, Violet continued to jerk the cock, which was still mostly hard, despite Kath’s explosive orgasm.
Kathleen blew out a breath and locked eyes with her sister.
“Stupid question, I know. Are you wet?”
Violet licked her lips slowly as she got up from her kneeling position, the salty taste of cum filling her mouth and nostrils. She reached up under her skirt, hooked her thumbs around the band of her sheer panties, and slid them down her legs quickly, kicking them against the wall. She then tore off her shirt and bra, which quickly joined her underwear against the wall, and pressed her snow-white breasts together while kneading her own nipples. Kathleen’s breath had become shallow again while watching her sister undress; any trace of flaccidity in her throbbing cock had left, replaced with steely muscle. She beckoned Vi forward with her chin, and Violet obliged, swinging one leg over her sister’s lap and draping her skirt around the huge penis protruding from where Kath’s vagina had once been.
Reaching underneath the fabric, Vi grasped the monster and positioned her hips so that, with a little gyration, the head of her sister’s cock rubbed against Vi’s clitoris, which slowly gorged and edged out of its little hood. Violet’s eyes rolled with pleasure and she slowly exhaled through her nose. Kathleen reached up and caressed her sister’s cheek and neck, feeling her pulse beneath the skin. She pulled her sister down to bite at her ear and neck as Violet ground against the shaft with her vag.
Violet, worked up by all this foreplay, suddenly came out of her pleasure-reverie, and quit grinding and blew out a breath.
“Ok Kath, brace yourself. I’ve only felt what you’re about to feel a few times, but it is unlike anything you’ve ever experienced.”
Kathleen grasped both arms of the chair she sat in, as though she were about to begin accelerating in a vehicle, and smirked at her sister, who stuck a couple fingers up her sopping-wet snatch, and painted the dick with her shiny lubricant.
Vi, with her tongue between her lips, slowly eased the head of the monster inside of her canal, feeling it expand as Kathleen flexed. It was bigger than anything Violet had ever taken before, but something about a huge member being inside her only served to increase her arousal. She angled her hips so that the cock was pointing straight up her canal, and sat down as hard as she could.
Kathleen felt every exquisite inch of her brand-new penis sheathed by Violet’s insides. Wet, warm tightness engulfed the monster completely, until she felt the head of her penis push up against what was probably Violet’s cervix, but it gave far enough to allow Violet’s ass cheeks to settle down onto Kathleen’s thighs. Violet gave a little grunt/shriek at the abrupt filling of every inch of her vaginal canal, while Kathleen groaned more and more gutturally the more of her cock that Vi took within her.
As Violet’s skirt pooled around their legs, she could feel the pulsing of Kathleen’s heartbeat within her, right about at the base of her stomach, somewhere amongst her intestines. It was something she had never experienced before, so she decided to just sit there for a moment and feel their heartbeats harmonizing while she got used to her emptiness being filled.
Kathleen buried her face in her sister’s amazing tits, and wrapped her arms around her, breathing heavily. Her sister was right, this was unlike anything she had ever felt. It was so hot and tight. She felt Violet’s arms around her, and her breath stirred her hair as she spoke.
“I can feel your heartbeat through your cock, sis. All the guys I’ve fucked and I’ve never felt their heartbeat.”
Kathleen grinned at Vi’s revelation. She pulled back from her sister’s embrace, and looked her in the eyes again. Both girls’ eyes held something more than lust at this point; their sisterly affection had grown a few measures by this extremely intimate bonding moment.
“Must mean something, yeah?”
Violet licked her lips again and nodded, leaning forward for a long, passionate kiss that Kathleen returned with increasing vigor.
Things would never be the same between the siblings.
They broke their passion slowly, reluctantly. Violet began to gyrate her hips, slowly and sensuously, feeling every small movement of the muscle filling her guts. For a few minutes, there was only gentle gyrations, and the small token thrusts on Kathleen’s part, all that she could manage in this position. They made love to one another, as only sisters in this specific situation could. Violet’s orgasm built slowly but concretely, every movement of Kathleen’s cock stimulating every inch and every degree of her vagina, including her g-spot. Her breath grew deeper, her eyebrows depicting distress as Kathleen watched and felt, and a glorious orgasm flooded over Violet in one great waxing and gentle waning. Kathleen watched the peaking of her sister’s please washing over her, the clenching closed of her eyes and the frowning and opening of the mouth as though to yell out, and then the slow relaxing of all muscles, the slow return of cognizance to her bright eyes. It was a glorious view.
Violet came out of her orgasm slowly, but smiled down at her sister, whose facial expression was one of a job well done. Vi smirked at her sibling, wiggled her behind a bit, and suddenly got an idea.
“Tell me if you can feel this, Kath.”
Kathleen cocked her head and waited. Violet relaxed every vaginal muscle she could, and, remembering her kegel training, clenched Kath’s dick with her vaginal canal as hard as she could. Kathleen gasped as the sudden sensation of Violet’s vagina grabbing and squeezing the monster took her by surprise. She gasped out a few a breaths at the unexpected pleasure, and Violet released her hold.
