Potential Part 24 by BiStander

They lined up at the end of Deana’s bed. Rebecca was the meat in a sister sandwich. Evan stood back a few feet, his heart pounding. Rebecca said, “Okay, girls, on three…one, two, three.” Simultaneously, they pulled their wraps away.

Evan gulped and said, “Oh, yellow, all yellow. Did you plan it that way?”

“Nope, it just happened,” Deana said. “What do you think?”

“Give me a minute,” Evan said. The tumbler was directly in front of him. Jason thought it was stupid, but Evan loved watching gymnastics on YouTube. To him, it was more erotic than seeing naked women fuck. He could freeze the video at any moment and examine the girls. It was exciting seeing what he wasn’t supposed to see, even if it was just their plump mounds or the crease between their legs that threatened to cave in and expose a pussy lip.

Deana said, “Well?”

“Bend over a little, and look straight ahead,” Evan said.

“Ooh,” Rebecca cooed and folded at the waist, putting her hands on the bed. Gloria went next. Deana gave him the evil eye before she followed suit.

Oh, did she know that would happen, Evan wondered? The yellow strip running down through the crack of Rebecca’s ass wasn’t wide enough. He licked his lips, imagining the tip of his tongue tracing the smooth outer edges of the brown dish that surrounded Rebecca’s puckered anal eye. She looked back at him. He shooed her dismissively. Satisfied that it was her ass he was staring at, Rebecca faced forward again.

At that moment, it dawned on Evan that Rebecca reminded him of the 2008 version of Shawn Johnson, except for Rebecca’s brown hair and that faint line of freckles under her eyes and down her nose. The tumbler bent over until her elbows were on the bed. Wow, Evan thought, they wouldn’t let Rebecca on national television in a gymnast’s outfit, not with that large pouch bulging between her legs. Fuck, the tiny tumbler’s fat pussy was like her mouth, too big for the rest of her.

“Phew,” Evan exhaled and turned his attention to Gloria. There wasn’t any gymnast to compare her to. Her butt was rounder, thicker and more like Candy’s than he ever realized. He had grabbed it, squeezed it, and fondled it, but he had never examined it in a bikini. Gloria had those smiley faces under each cheek. The top of the bikini had to bridge the groove that would funnel water down into the deep valley. He wanted to lift one of those thick ass-meat globes and drop it. It would do that sexy jiggle thing he loved. Shit, my kid sister has a serious badonkadonk, and I’m getting a boner for it.

“Ah, come on,” Rebecca said. “Just admit you think Gloria has the best ass you ever seen, then tell Deana her glorious bubble-butt is nicer than my skinny butt.”

Fuck, Rebecca’s glorious pussy was right there, mocking him like the target at the dunking booth. He stepped forward and bumped her ass with his groin and laid one hand on Gloria’s butt and the other on Deana’s. It was outrageously erotic touching both of his sister’s butts, neither knowing about the other, and his balls rested against the tumbler’s backside.

Rebecca pushed up on her toes, rubbing Evan’s stiff cock between her cheeks. He hunched and ground it into the groove while his fingers rounded the inward slope, down into the deep, warm valley of Gloria’s ass cheeks. She didn’t respond, so he challenged her as he had in the kitchen yesterday. The ring around her asshole heated the tip of his finger. He circled the rim like a roulette ball ready to drop, then followed the slick material down. The crotch patch bridged the divide between the high ridges of Gloria’s plump lips. He tested the strength, collapsing the fabric into the groove. Gloria finally gave him her attention. Her expression dared him to keep going. The problem was, he could tell from the look in her eyes that his sister would let him finger her right there in front of the other girls. Deana couldn’t know anything about him and Gloria, and Gloria couldn’t know about Deana. It was crazy and exciting like a Sidney Sheldon novel.

Evan groped Gloria’s crotch then whacked hers and Deana’s ass at the same time. “I can’t choose one. They’re all perfect, best in class.”

“You have to,” Rebecca said.

“It would be like choosing the best apple while tasting a plum, an orange, and a grapefruit. It can’t be done. They are all perfect.”

“Okay, then,” Rebecca said, “have a taste and decide which one you rather tongue fucked.”

“Rebecca Stevenson,” Deana said. “You want Evan’s birthday present or not?”

“Of course,” Rebecca said. “But—”

“No buts,” Deana said.

“Um, I see three butts, but what birthday present? I didn’t get her anything, ah, yet,” Evan said.

“You know,” Deana said, “kiss her, she wants a birthday kiss.”

The hair on the back of Evan’s neck rose. It would be the trifecta of erotic kisses. He would have his lips on Deana’s lover while she watched. Rebecca kissed his sister, who was his lover. And best of all, he would be kissing the mouth that tasted Deana’s pussy. Evan shrugged and said, “If I have to, okay.”

Under the influence of the tumbler, Evan blacked out. Her firm body contour to his, working in unison with her mouth. Kissing her was a whole body experience. Her legs touched his, her pelvis rubbed, her hard nipples poked into his chest, and her hands and fingers worked on his neck and shoulders. The girl’s mouth was strong, and her tongue did gymnastics with his. No wonder Deana loves her.

“Rebecca, don’t try and get an extra birthday present…tonight,” Deana said.

Evan heard the tone of Deana’s voice and forced himself to stop. The cute in Rebecca’s face had been replaced with a burning passion. Before she turned away from Evan, Rebecca smirked, gesturing at his throbbing erection. He said, “Happy birthday.”

“Thank you,” Rebecca said. “You still have to give me something.”

Evan figured that, but the way she said give me something made him think that he wouldn’t have to go shopping for what Rebecca was expecting. How incredibly hot would it be to fuck Deana’s girlfriend while she watched?

“Who kisses better?”

Rebecca didn’t react, but Deana and Evan’s head whipped around toward Gloria. They asked in unison, “What?”

“I’m not sure,” Rebecca said. “Let me see.”

Evan could feel the pounding of his heart in the head of his dick. Girls kissing was hot, but his sister kissing the tumbler in front of him and Gloria was out of this world erotica. The expression on Gloria’s face suggested she agreed. “Should we leave?” Evan asked.

“I, ah, I’m not, mm, not going anywhere,” Gloria said. “Looks like Deana might kiss better than you.”

“Hey,” he said.

“We need a second opinion,” Rebecca said.

Gloria said, “Okay.”

“Kiss Deana first,” Rebecca said. “I got her warmed up.”

“No,” Deana said.

Evan was more than warmed up, and if Gloria and Deana started making out, he would blow a load in his sweatpants.

“I’ll kiss her then,” Rebecca said and held Gloria’s face, then locked lips with her.

Evan turned to Deana; she looked as flustered as he felt, but not shocked like he thought she would be. He pointed at the inflamed pink of her aroused nipples, bleeding through her shirt. She crossed her arms over the bloated tit caps and looked at his groin. Evan fluffed the front of his pants, trying to hide the irrefutable evidence of his excitement. It was useless, though, without the elastic band of boxers to trap his boner. He ignored it and joined Deana, watching their sister and the tumbler. It looked like an audition for a lesbian porn movie.
