Chapter 3- Control Is Overrated
Kelsey woke up, feeling pleasantly rested. She hummed and stretched out before bending in the middle and moving her behind backward to find and rub against her sister.
She couldn't find Jane.
The older girl frowned and turned over, seeing that her sister's side of the bed was empty. The towel that Jane had been sleeping on was still there but cool to the touch, she hadn't been lying on it for at least a couple of minutes.
Kelsey sat up and rubbed her eyes. She wasn't worried about where Jane was, she was more or less just disconcerted by the lack of contact she had expected upon waking up. She cricked her neck and massaged her belly, trying to banish the remnants of sleep away. The curtains were closed, but she could see a bright morning sun outside.
She got up and slowly walked out of her bedroom, trying hard not to waddle. She wiped at her eyes again with her knuckles while she headed down the hallway toward the bathroom. Ben had been playing kickball with her bladder all night, seemingly, and now she was needing to do something about it.
She opened the door to the bathroom and paused- Jane was panting and moaning as she straddled the edge of the bathtub, sinking up and down on one of her suction cup dildos. She was facing away from Kelsey and the door, leaning forward and her sister got a stunning view of her amazing ass and her wet pussy sliding along the length of the toy, leaving it glistening.
"Might've known I'd find you impaled on something when you weren't in bed." Kelsey muttered as she came into the bathroom and headed to the toilet. Jane shivered at the unexpected sound of her sister's voice, turned her head and smiled, not pausing in fucking the stout rubber cock.
"Hey," the blonde girl breathed as she watched her sister enter the room. "Was really horny and didn't want to interrupt your beauty sleep."
"I actually woke and tried to squirm my ass against yours, but you were gone," Kelsey said as she plunked herself down on the toilet seat, less than a foot away from her sister, who was still writhing, her skin shining with sweat. "Can't believe you started without me."
"Oh, I'm sorry," Jane replied, reaching over and caressing her sister's knee. "I really thought I was being considerate. I never would've left without you if I thought you didn't look so beautiful sleeping like that."
Kelsey blushed and squeezed her sister's hand before releasing it, letting Jane continue to fuck her dildo ardently. "Well, at least I get a show..." she mused.
"Don't I get one?" Jane pretended to whine, pouting at her sister. "I mean, you're right there."
"I'm peeing, you dingbat," Kelsey replied, suddenly very conscious of the fact that she was peeing and it sounded like a thunderous waterfall in her ears. "You want to watch me pee? Even if I
were
to agree to that, may I point out that you couldn't possibly see anything, even if I spread my legs, because my titanic belly is in the way."
"Yeah, I guess that's true," Jane sighed. "Still, I'm happy you're here and you can watch me, right?"
"Definitely," agreed Kelsey. "You look amazing riding that thing, darling."
"Hey, I know," Jane panted, sitting upright and massaging her breasts. "When you're done, why don't you kneel here and you can kiss my belly and talk to Kaylee while I do this?"
Kelsey blinked. "Me... talk to your unborn child while you fuck yourself into orgasm?"
"Well, of course it's going to sound weird when you say it like that," Jane panted, her hairline now damp and her blonde locks clinging to her skin. "Then just come over and suck my tits. I'm leaking, I might add..."
Kelsey shook her head and sighed, still not exactly sure how she'd talked herself into all of this. She slipped off the toilet seat and knelt down next to Jane, placing a hand on her thigh. She did indeed feel a tingle as she watched her sister squirm up and down lustily, her pussy making squelching noises as she fucked the fake cock.
She placed her cheek gently against Jane's stomach, acutely aware of her sister's heavy breathing, hearing her heart beat rapidly and the building warmth of her skin. She caressed the taut skin of her belly and kissed it gently, almost immediately lost in reverie at the notion of her sister and the niece she was waiting to meet.
"Mmmm, Kels, I love feeling your lips on me," Jane moaned as she moved up and down, her eyes closed. "It's heaven."
Kelsey kissed her way up until her lips met Jane's breast, which she gently began sucking on and swirling her tongue around. The blonde girl shuddered and groaned, squirming even harder on the dildo inside her. Kelsey used her lips to form a firm seal around the nipple and sucked, searching for traces of the salty-sweet milk she'd taken from Jane before. They'd agreed to milk one another until the babies arrived, hopefully making production and pumping easier.
The fact that it turned them both on was a side-benefit, for sure.
"Gnnn, Kels," Jane panted, arching her back and pressing her breasts forward to her sister. Kelsey's hand took the breast she wasn't sucking on and massaged it, squeezing, and brushing her fingers over the nipple, causing Jane to shudder. "Oh, God, you feel so good..."
Jane was now writhing almost uncontrollably, her breath coming in gasps as she fought for control, balanced on a knife's edge of unreal pleasure. Kelsey's arm wrapped around and gripped her sister's ass, helping to bounce her up and down while her other hand snaked down beneath and gripped the base of the dildo, as if to hold it in place. She could feel Jane's heated, slippery pussylips split around the dildo, pressing against the back of her hand as her sister slammed down desperately. Kelsey released her grip on Jane's nipple and rose up to look into her sister's eyes. Jane threw her arms around the brunette's shoulders, pressing her forehead against Kelsey's.
"Are you gonna cum, Janie?" Kelsey whispered eagerly, her sister's breath on her face. "Are you gonna cum hard?"
"Gnnnnn, yes!" wailed the younger girl, her fingers gripping Kelsey's neck, massaging feverishly.
