While Benjamin was still dumbstruck that his poodle, once his obnoxious brother, was now his super-sexy aunt, she was sashaying down to the kitchen following her slightly younger sister, Mimi. She found her eyes drawn to Mimi's ass as they went down the stairs. For reasons unknown, she was increasingly horny and almost felt like she was in heat.
"So, what are we making again?" said Janette, still stealing glances at her sister's posterior when she wasn't looking.
"Potroast," replied Mimi, looking up at her older sister and narrowly avoiding catching her in the act.
"Oh, swell," said Janette, noticing how hot it seemed all of a sudden.
They got down into the kitchen and shut the door, closing them off to the rest of the house. Janette was glad for the privacy, and Mimi was getting all of the stuff needed to prepare the family meal.
"So, how's Maggie?" asked Mimi, snapping Janette from her trance-like staring.
"Oh, um, good. Want to see her newest picture?"
Janette went to her purse, sitting on the counter, and produced a picture, then showed it to Mimi. She was blonde, with fair skin and wearing a cheerleading uniform Mimi was silently jealous of her already enormous breasts, easily a double D at the age of 16, and her great legs. Not that she was a slouch herself. Mimi was proud of her own body, from her just-at D cups, tiny waist, and great legs and bouncy butt. She thought she looked damn-good for 35, but not nearly as good as her sister did at 40, with those massive mammaries, giga-butt and absurdly tiny waist.
"She looks great," she said sweetly, covering up her envy. "How you two don't have broken backs, I'll never know."
"Just good jeans, I guess," replied Janette, with the barest hint of venom in her answer.
Mimi blankly smiled, and turned to prepare the food. She bent over to get a tray from the pantry and Janette used the opprotunity to bend down enough to see her ass. She nearly gasped when she saw her sister in a very tiny thong.
"My my, thinking we'll get lucky tonight, eh?" she said with a playful tone, then smacked her sister on the bottom, eliciting a squeal of pain from the shocked Mimi.
"Were you looking up my dress?" asked Mimi point-blank.
"I couldn't help it; I was bending down to help out when I accidentally got a peek," she said with all the false honesty of a child with a slingshot behind his back. Apparently she still kept some of her traits from being Jonathan.
Mimi, however, was not amused and pulled her skirt down and smoothed the creases, as if she thought it would stop her sister.
"Yes, well, let's just start dinner, shall we?"
"Oh, come on..." said Janette in a slightly playful voice, "Remember when we would...explore when Mom and Dad weren't home? Remember cuddling together after seeing 'Alien'? Didn't you have fun with me?"
Mimi was getting out a bowl when she suddenly stopped.
"Yes...yes, I do remember all that. But we're adults now, and none of that was right, even when were just girls."
"But you DID have fun, right?" inquired Janette.
"..y-yes..." said Mimi, weakly, standing at a counter about to pour some instant mashed potatoes.
"Did you have fun with me?" said Janette quietly.
"Yes, I had fun with you," replied the younger sister at an equal volume.
"Don't you ever wanna do it again?" She inched closer to her sibling
"Yes..."
"Can we...?" Janette said hopefully. She was right behind her, her crotch on Mimi's ass.
"No! It wouldn't be right!"
Janette pushed a little, and her hands drifted up towards Mimi's chest.
"C'mon...please? One more time?"
"No..." said Mimi quietly. Janette stuck her hands into the exposed area of Mimi's shirt, feeling around at the soft flesh.
"Say yes..."
"No!"
"Say yes..."
"No."
"Say yes...!"
"No..." Janette's skilled fingers found both of the nipples.
"Say..." Her fingers got into position. "Yes." She squeezed them as hard as she could.
"OOHHHHH...!" Mimi exploded. "OH, YES! OOHHH, YESSS! YES, YES, YES, YES, YESSS!"
Mimi swiftly turned around and kissed her older, taller sister very deeply, their hands now free to play with each other's bodies. Janette's hands were still embedded in Mimi's cleavage, while Mimi was kneading Janette's ass and gently rubbing up and down her asscrack.
"So..." Mimi all but whispered after breaking the kiss, "What first?"
"I think I've got an idea," said Janette at the same volume, "Get up on the county, baby sister."
Mimi complied, helped along by a swift smack to her squishy ass by Janette that she, this time, enjoyed. As the two sisters continued their years old romance, little did they know that someone was watching...
