Joey sat, played with some features of his app he had learned about earlier, and answered the survey, which consisted of a few questions about how he used the app. He texted Adam to see if he was still out with Kelly and went to the kitchen to get a quick bite to eat. While sitting at the counter eating a bowl of cereal, Jane came down from her room, having just taken a shower; her hair pulled up in a towel, she wore a long, baggy T-shirt that reached her upper thighs.
“Where’s the little dork?” Jane asked.
“He went home. I think his girlfriend was meeting him,” Joey answered while watching his sister in the kitchen.
Her fat body looked sexy as she walked around the kitchen getting the stuff for a bowl of cereal. She stole a glance back at Joey while bending down to get ice from the freezer.
“Enjoying the view, Dork?” she teased.
“Damn right,” Joey replied with eyes glued to her backside.
She reached back and pulled her shirt up, revealing her wide, naked ass. Joey growled deeply, looking at the curves of her ass and hips. The curve of her ass came out from her thighs sharply and ended with an equally sharp curve to her lower back. When she stood up, she kept her shirt up, emphasizing the roundness of her ass as the t-shirt rested on the top of her ass cheeks. She wiggled her ass for Joey, and the T-shirt slipped back down, covering her up again.
His phone dinged with a notification, and he read the text from Adam. ‘Still hanging with Kelly, will be home by midnight. I texted Mom.’
She sauntered over to the counter, sat next to her brother, and made herself a bowl of cereal.
“So, Brother,” she started.” Exactly how many people are you fucking these days?”
Joey coughed and almost choked on his cereal with the blunt question. “Seriously, Sis?!”
“Do you think I’m an idiot, Joey? Mom has been all over you and has been totally dom’ing, Dad. I gave you my virginity. I’m pretty sure you’re fucking the testosterone right out of our brother, and tonight I watched your friend Steve, who happens to have tits, ride the anaconda in your shorts. So, I’m just wondering what the hell is going on with my brother,” Jane said directly.
“Well. Sis, to be honest, it’s been a crazy week. I mean, I just lost my own virginity on Saturday, and for some reason, everyone around me is obsessed with my dick. I mean, don’t get me wrong, I love the attention, but I’m afraid of messing with people’s heads, and I don’t know. Making people jealous or mad,” Joey replied. “Plus, Steve and Adam are both going through changes; it looks like the same thing Kelly went through last year.”
She leaned over and kissed her brother on the cheek, then replied, “Joey, I have to admit, it is crazy that you and I are sleeping together, but it doesn’t really bother me that you are fucking other people. It surprised me to see you giving it to Steve earlier, but after seeing him come in for lube, I understand. Practically speaking, he’s a girl already,” she continued. “I don’t know what to say about messing with other people’s heads and all, just be honest and don’t mislead anyone.”
“Wait, were you spying on me from Adam’s room?” Joey asked.
“Homework, huh? Since when do you do homework? I’m sure Mom figured it out, too. She dragged Dad to bed shortly after you came up here,” Jane replied. “She was probably hoping to come up here and play with you herself.”
“How much did you see?” Joey asked.
“Pretty much the whole thing. I had a straight shot from Adam’s room. With the light off, you couldn’t see me, and when Steve came in, I slipped behind the curtain. He’s got cute tits and a round ass. If I were a guy, I’d wanna fuck him too,” Jane continued.
“I can’t believe I’m having this conversation with you, Sis,” Joey said, shaking his head in disbelief.
“Seriously, Dork. I liked it. And the thought of you and Mom, or you and Adam. It lights me up,” Jane said.
“You remember Mrs. Tyler, right?” Joey asked.
“Yeah! I miss her. She was always so cool to us,” Jane replied.
“She’s been all over me the past couple of days,” Joey told her. “Talk about a sex fiend. I think her husband mistreats her. Maybe cheats on her and stuff. She said it’s been a long time since she did stuff.”
“So you’re like, Dr. Love. Sweeping in to take care of the lonely wife?” Jane teased.
“It’s not quite like that, I hope. Mrs. Tyler said she didn’t plan to run off and leave her marriage,” Joey said thoughtfully. “I hope it doesn’t get weird.”
Jane finished her cereal, scooted her stool closer to Joey, leaned in, and started kissing his neck.
“So you like your girls big and your boys slender, huh?” she teased.
Joey shivered with goosebumps as his sister ran her tongue along his neck and behind his ear.
“Y, yes,” Joey said as his sister took his hand and guided it under her shirt.
He slid his hand up her thigh to her hips and caressed the fat curves accentuated by her seated position.
“Do you like your sister’s curves? Her wide hips and fat ass? Her bulging belly and big, sloppy tits?” she continued to tease.
“Yes,” Joey stammered, as he grew excited.
“Maybe we should go to your room, and I can let you do what you want with me,” Jane suggested. “Maybe you can show me what you and Mrs. Tyler have been up to,”
Jane continued while now rubbing his shorts closer to his hardening shaft. She stood and pulled Joey along by his growing erection, smiling back at him.
“C’mon, my sexy brother. Come up and ravish me,” she said.
When they got to Joey’s room and closed the door, Joey remembered the outfit he bought for his sister.
“Hey, Sis. Can we play dress-up?” Joey asked.
She squinted at Joey suspiciously, saying, “I figured you’d want me naked, not dressed.”
She pulled the shirt off over her head, and Joey was now conflicted about his suggestion. Seeing his sister’s body completely aroused him, but he couldn’t help imagining her in the sexy Tracer costume he bought for her.
“Well, I bought it for you, and now I have it in my head. I want to see you in it,” Joey said while he reached into the closet. He pulled the bag out and laid out both costumes on the bed.
“That pink one is not gonna work,” Jane said, raising her eyebrows. “Maybe the yellow, but it looks kinda tight.”
“Yeah, they’re meant to be tight. They’re Overwatch Cosplay outfits. The pink one’s for Adam,” Joey explained.
Jane picked up both outfits and held them up to see. She laid the yellow one up against her body and looked down before tossing them both back on the bed.
“Give me your phone, Dork,” Jane said, holding her hand out.
Joey fished out the phone, unlocked it, and handed it to his sister. She brought up the messaging app and started texting.
“Wait. Who are you texting?” Joey asked, trying to peek at his sister’s antics.
“Don’t worry about it. You’ll find out later,” Jane said, turning away from Joey. “If you want me dressed up like some hyper-sexbot babe, you won’t look at your phone till later. Deal?”
“Deal!” Joey answered excitedly.
She put the phone on Joey’s dresser, took both outfits into the shared bathroom, and closed the door. Joey removed his clothes and lay down in the bed awaiting his sister. He heard a few curses and grunts coming from the bathroom, and finally, the door opened. Joey’s cock ached at the anticipation of his sister dressed in the sexy outfit, but he thought he would cum on the spot when she walked through the door. The bright yellow thigh-high stockings hugged her legs so tightly her thighs bulged out over the edges. The shoulder/waist strap component of the costume wrapped around the curves of her breasts, hips, belly, and ass with clips holding the thigh stockings up. It functioned like a garter belt but went all around her body and over her shoulders. A skinny pair of bikini briefs with the logo on the front, as well as matching bra cups, adorned her body. She pulled her hair back into pigtails and walked to her brother’s bed. Joey watched, speechless, while his sister climbed into bed with him and crawled over to greet him with a kiss. He laid his arm around her large body and moaned at the luxurious feel of his sister’s body encased in this costume. She proceeded to kiss and lick all around his neck, ears, and mouth.
“Does my brother like seeing his fat sister in this sexy outfit?” she whispered while kissing him.
Joey nodded as he ran his hands all over the curves of her body.
“Does my brother want his fat sister to suck his cock?” Again, Joey nodded. “Does my brother want to fuck his fat sister again?” Joey nodded.” And does my brother want to fill his fertile fat sister’s cunt with his cum?” Joey nodded, getting more excited as the minutes drew on. “Does my brother want to see his fat sister bulge out when she gets pregnant and leaks milk everywhere?”
Joey couldn’t take it anymore, and he rolled his sister’s large body over, started kissing her, and grinding his dick against her satin-covered legs. Jane was giggling from the attention as Joey lifted her knees and dove down between her fat thighs. He pulled the sexy panties aside and started sliding his tongue right up along her slit, which was leaking fluids down over her ass. He slid his tongue again, this time reaching down between her ass cheeks and pulling them apart so he could get his tongue all the way down. He could taste her delicious juices as he had before and continued to lap them up. She giggled some more, grabbing her brother’s head and encouraging him.
“You’re so fucking sexy, Sister,” Joey said as he kept licking her fat pussy and ass. She lifted her legs higher and pressed Joey down to her ass again.
“Lick my ass some more, Brother. That feels amazing!” Jane appealed.
Joey obliged and started licking all around her tight hole, causing her to spasm a bit. He pressed his tongue hard against her ass, and it entered just inside, and instantly she squirmed and pulled his head tighter to her bum.
“OH my gosh, Joey! M more!” she begged.
