Jason and Jamie were eighteen year old twins, but they were the exact opposite. Jason was very outgoing while his baby sister (by twelve minutes) was very shy. She didn't date much, even though she was very pretty.
They shared a bathroom, so Jason had peeked in on her in the shower alot. She had large breasts which was part of the reason she was so shy. She didn't talk to boys much and had never had a date.
Jason on the other hand had girl after girl sneak into his room at night for some taboo meetings. Jamie heard these girls come in and all the activitys til they left.
One summer afternoon, Jason took a quick shower before laying on his bed naked. Thier parents had gone away for the weekend and he had a party to plan for.
Jamie knocked before walking into his room. She was too fast though and he didn't cover himself fast enough. His penis was large even when it was soft. She was embarrassed and looked down at the floor.
He wrapped his towel around himself before asking, "Do you need something?"
Her cheeks were red, she mumbled, "nevermind" before racing from his room.
He found her on her bed crying. Sitting beside her, he ran his hand over her back, "Sorry for yelling, you surprised me. Did you need something?"
"Well, I only came to your room to ask you to teach me to dance. I want to impress Mark Kingstov tomorrow night at your party and I don't know how to do any of the sexy dances he likes."
Jason laughed, "Mark? He's a jerk, don't waste your time with him! She buried her head back against the pillow crying. Sissy, I'll teach you, if you stop crying."
"I don't like Mark, but if you want to impress him, I'll help you. She sat up smiling, he hadn't called her Sissy since they were six. Put on something sexy and meet me in the basement in half an hour."
She stood in her closet, she couldn't find anything sexy at all. Her parents didn't let her wear anything sexy. She went to her parents room, she needed something sexy and if anyone could dress sexy it was her mother.
She opened her mothers closet, she found a sleeveless tight black dress, it barely covered her large tits then the dress stopped barely below her ass cheeks.
If this wasn't sexy, Mark was blind! She went back to her room for a tiny black lacy thong and her stillettos that she kept hidden in her closet. She put on a touch of make-up before tying her hair back loosely.
She entered the basement and Jason let out a loud whistle. "Damn, if you weren't my sister, I'd fuck your brains out."
She was taken aback by his comment, but she needed him to help her learn to dance.
"Teach me to dance jerk! She threw back at him!"
"Give me a minute sissy, I gotta go change, you're early. He ran up to his room, took a quick two second shower to wash the sweat off before throwing on a thong and jeans. He didn't need a shirt to teach her to dance."
He rushed back to the basement, Jamie was perched on one of the bar stools. He went to the stereo to put on some sexy music. As soon as he flicked the song on, the vibe in the room changed. His hot little sister was looking mighty fine.
He lowered the basement lights and pushed the couch against the wall clearing them a dance floor. He guided her to the middle of the room, standing behind her. He put his hands on her hips & began moving his hips to the music. "Move with me sissy," he said.
She began to sway. "No, no, shake that ass of yours girl." As she did, her ass bumped into his crotch. His penis started to rise.
He stepped back from her, he didn't want her to know she was causing him to get hard or she wouldn't continue.
Once she got the hang of grinding, he pulled her closer and showed her how to move up and down in front of him.
All the movement against his cock and the fact that his sister looked amazing wasn't helping. Next he spun her to face him before showing her how to go down to the floor and come back up without falling. She was doing great.
"Ok sissy, time for a practice run. I'll be Mark and you come over to me and ask me to dance. Let's get a drink while we do."
He went to the bar, poured himself a large Jack and Coke while she popped the top of an expensive bottle of wine. She downed a glass before getting the nerve to approach him.
