As Jeff headed downstairs he could hear his mother and sister talking in the dining room.
"Oh my god Mom, did he steal them?!"
"No Carol, he didn't steal them."
"Then where'd he get the money? Wait, are they fake? Here, let me try cutting the bottom of this glass..."
Jeff stepped quietly into the dining room. Carol was holding up her water glass in one hand, and his mother's new diamond pendant in the other.
"Carol," Jeff said, "don't worry about where they came from, just accept that they're real and were mine to give her."
"Sure thing Bro!" Carol let go of the pendant and set her water glass down. "Glad you decided to join us for dinner. And you'd better have some goodies for me too!"
"Sure, no problem Sis." Jeff smiled. "Oh Carol? have you noticed that Mom's going braless around the house tonight?"
Carol rolled her eyes. "Duh, her boobs are practically falling out of her top."
Jeff's mom blushed at the exchange and focused on serving herself from the bowls of steaming food.
"I'd prefer if you also took you bra off for the night." Jeff said sweetly.
"Ew! here at the table?" Carol gaped at her brother.
"You can step into the kitchen to remove it," Jeff allowed, "but there'll be no more bra wearing at our dinner table."
"Yeesh, guy gives out some diamond jewelry and suddenly he thinks he can call the shots." Carol pushed back her chair and stood up.
"Carol, do what your brother says." Jeff's mom said without looking at her daughter.
"I, fine." Carol stuck her tongue out at Jeff before stepping out of sight into the kitchen.
Jeff filled his plate with food. As much of a brat as his sister was, she really could cook. He glanced over at his mom. She was turned partly towards him, and was holding her shoulders back as she ate, but was having trouble seeing past her tits to her plate. Jeff felt an erection beginning in his pants; his mom was certainly trying to deliver on the 'sexy look' he'd said he liked!
Carol came back and stood next to her chair. "Okay, I'm braless, happy now?" She arched an eyebrow at Jeff.
"Hmm," Jeff made a show of looking his sister over. Her breasts were bigger than their Mom's had been, but nowhere near as big and perky as hers were now. She was wearing a t-shirt and jeans. "roll up your shirt until your nipples show like Mom's."
"Jeff!" Carol blushed furiously. "Why would you want to see my nips--either of our nipples?! I'm your sister!"
"So be a good sister and get rolling! From now on you and Mom are going to dress sexy for dinner, and if I don't think you've done a good enough job you'll have to eat naked instead."
"Mooom! Tell Jeff--"
"Carol, you heard your brother! If he wants to see your breasts hanging out of your shirt that's what he'll get." She crossed her arms over her ample chest and glared at her daughter.
"Fine." Carol stuck her tongue out at Jeff again and rolled up her shirt until her nipples were half exposed. She tied a quick knot in the back, pulling the shirt tight and squishing her boobs to stick out below the edge.
Jeff reached over and tugged up on the shirt until the nubs of his sister's nipples were peaking out from under the roll of cloth. He ran a finger tip tracing the half-moons of her aureola and smiled as he heard her gasp. His erection was throbbing harder than ever.
"Jeff," Carol looked wonderingly at her brother, "does that teepee in your pants mean you want what I think you want?" Carol licked her lips smiled at her brother.
"Honey?" Jeff's mom leaned towards him and tugged her sweater down a bit further exposing more of her own nipples. "You know momma will give you anything you want." Her voice was soft and husky and the look she was giving him, like the look upstairs, promised amazing things.
Jeff smiled and decide what to ask for next.
