Christine twisted around, took Jackie into her arms, planted a kiss on her lips, and caressed her breasts through the bra she still wore.
“Do you think they make this bra in my size?” she asked.
Jackie looked down to where her sister’s fingertip was running along the lacy edge. “Not sure, but they come as a set.”
“But I already have the panties.”
Jackie swatted her sister’s hand from the bra. “You can’t keep those, I only just got them.”
“Sorry, Kie. They got all wet when I showered. You’ll have to go home commando.”
“Well, after what you did when we were younger, make sure I get them back in one piece.”
“That’s not fair,” complained Christine. “When I cut holes in those panties, I didn’t know you could buy crotchless ones.”
“They were my stolen panties you cut holes in, Chris. After you put them back, did you expect me not to notice?”
Christine sniggered. “I expected them to get you some much needed attention, seeing as all the boys only wanted me.”
“It was your big tits that got the boys attention. One look at them and I may as well have been invisible.”
As if to emphasise the point, Jackie buried her face into Christine’s tits and pretended to drown.
“You were jealous,” laughed Christine, holding her sister in place until the need for air became genuine and her struggle, real.
“Did you say, jealous?” gasped Jackie after being released. “Of course I was jealous. You were younger than me, but with tits ten times the size.”
“Your tits are a nice size,” Christine replied, giving her sister’s a squeeze that became a caress.
Jackie added her hands to her sister’s. “They hardly got bigger when I was pregnant with Steve, though by then I didn’t need them as a boy magnet.”
Christine dropped her hands. “Just be grateful your Rob was an ass man. My Dave lost interest in my big tits, after a younger and more bouncy pair came along.”
“Sorry, Chris, I didn’t mean for the conversation to go there.”
“It’s okay. If I hadn’t discovered Dave’s affair, we might not have got together, and I wouldn’t want it any other way. I’m just sorry your Rob isn’t here to still be a part of this.”
Jackie sniffed away a tear and pulled her sister into a hug. “Remember what he used to call us?”
Christine grabbed a handful of Jackie’s ass and cried, “Twins of the Rear! He’d line us up side by side, asses at the ready, then finger one while fucking the other before switching, always giving equal attention. When we were on the verge of cumming he’d do his best to get us off together, and wouldn’t stop until all three of us had cum.”
“Remember when he first caught us fucking each other? He waited until our shock at being found out turned into a babble of apologies, then, instead of being outraged, just took out his cock.”
“And our race to his cock when we realised he wanted in.”
“Which you won,” complained Jackie, giving her sister’s ass a light slap.
“Ow!” cried Christine, before returning the slap. “I stopped and offered his cock to you, seeing as it was your husband’s.”
“Only because you knew I’d let you have your first taste. I didn’t think you were going to suck a week’s worth of cum from him.”
“It was the sight of you licking my ass while I sucked his cock that got Rob to cum so hard.”
“He did come hard,” agreed Jackie with a wistful smile.
“Are you sure you don’t want me to get Rob Junior out and give you the ass fucking you love?”
“I’m sure,” replied Jackie, knowing it couldn’t possibly top the one she’d had from Steve.
“Then all that’s left is more sister on sister pleasure time. Have you recovered enough to go again, old woman?”
“I’m not that old, you big titted tart,” replied Jackie. She pushed her sister onto her back then straddled her hips.
Christine held her tits together and pointed them at Jackie, who removed her bra then leaned forward until their nipples touched. Bending her head, she pressed her lips to Christine’s.
With mouths locked and tongues entwined, they caressed their tits and Jackie started to fuck her swollen clit and spread cunt lips against the hard crown of Christine’s pubic bone. The action soon triggered another orgasm in Jackie, who rubbed all the harder and faster as the sensation grew, coating her sister’s mons in a flood of pussy juice.
Breaking the kiss, Jackie transferred her lips to Christine’s neck and started a slow journey down her voluptuous body. Sliding onto a thigh, Jackie continued to fuck, aided by Christine, who pushed her leg hard against her sister’s still spread cunt. Jackie moved her lips to Christine’s puckered nipples, sucking away until they stood well proud of the acres of warm tit flesh.
Slipping a hand between her sister’s legs, Jackie clamped two fingers deep into the steaming hot pussy she found there, and began flicking a thumb on her clit. Something she knew drove Christine insane.
When the urge for release became unbearable, Christine pushed Jackie clear and rolled her onto her back, then straddled her face. Taking hold of her sister’s head, she pushed the needy gash to Jackie’s lips.
Sucking her sibling’s cunt into her open mouth, Jackie tongued at her folds, pushing Christine over the edge. Jackie eagerly drank down the fluids that gushed from her sister’s swollen pussy, which shuddered and pulsed in an unrelenting orgasm
Driven ever onward by her sister’s oral actions, Christine kept cumming and cumming. After what seemed like forever, an exhausted Christine collapsed back onto her sister’s body and just lay there, the room spinning in her vision.
When their panting for breath had begun to subside, Jackie started to laugh.
“What’s funny?” demanded Christine, slapping at her sister’s body and finding a hip.
“Who’s the old woman now?”
“This doesn’t count, you know my legs don’t work after I’ve had a really good seeing to.”
Jackie tried to lift the leg that straddled her body. It was a dead weight from which she couldn’t extricate herself. “What if Kim should come home and find us like this?”
“Then she’d think we’d been gangbanged and left for dead.”
“Except we’re not covered in spunk.”
“Now that’s a detail I miss. Remember the time Rob was running late and we started without him?”
“Oh, yeah,” recalled Jackie. “He watched from the doorway until we’d fucked ourselves to pieces.”
“Then, while we were powerless to stop him, jacked off over our wrecked bodies.”
“You told him to cum on my face,” added Jackie.
“And what did he do?” asked Christine.
“He took aim at my face, then, at the last second, switched over to yours.”
Christine chuckled at the memory. “I only got the first spurt.”
“And I only got the fourth. The second and third landed across our tits.”
“Did we rub it into our skin or lick it off?”
“I think a combination of both.”
Christine smiled at the memory. “I loved licking his cum from my tits.”
“And I always envied that. I can just reach a nipple with the tip of my tongue, but it hurts my neck.”
“You shouldn’t envy these beasts of mine, they’re a right royal pain in the back and I can’t wear something as flimsy as that diaphanous bra you showed up in.”
“Which is why I’ll need those panties back.”
