Growing up with his sister, who was four years older, Mike wasn't as outgoing as she was. Mike often shied away from girls and tended to bury himself in schoolwork. His birthday was close to Christmas, one thing that he had always disliked. Two days before his eighteenth birthday, Helen brought a few friends home to prepare for a party they were going to.
Mike was in his room when Helen introduced them to him. They were all dressed and ready to go out. They all had short skirts and low-cut tops. Helen was dressed similarly. Mike felt his cheeks redden as they all came over to him and kissed him on his cheek. They laughed and giggled, making him blush, but Helen quickly cut them short and sent them out of his room.
"I am sorry, Mike. That was mean. Which one would you like for your birthday?"
Mike was shocked. He told Helen that he had liked the one with long dark hair, like hers.
Helen smiled and kissed Mike on his forehead, and left his room.
It was Christmas Eve. Helen came home, dressed, and told Mike she was taking him to a party. She told her parents that they would be back later and get a taxi home, as they were going to go to Ray's, Helen's boyfriend's house.
Paul was three years older than Helen. They had been seeing each other on and off since Helen was nineteen.
Helen and Mike took a taxi to Ray's. Helen had dressed in leggings and a black top that was cut low enough to expose the tops of her breasts, with just a hint of cleavage. Mike had put on jeans and a turtle-neck sweater. When they arrived, they were met by Jackie. She hugged both of them. Jackie was the girl that Mike had told Helen he liked.
Ray poured them all drinks, and they sat around chatting. Jackie was on a chair, while Ray and Helen had the sofa, leaving Mike sitting on the floor opposite Jackie. He was doing his best not to keep staring at either his sister or Jackie, but whenever he looked towards Jackie, he had almost the perfect view of her dress. They ordered food and ate it around the small coffee table. The drinks were going down well, and at about 10.30 pm, Helen suggested that they play cards.
Helen sat between Mike and Ray, with Jackie opposite Mike. Helen dealt and announced it was strip poker.
Mike started to protest, but Helen told him not to worry. The drinks flowed, as well as the hands of cards. Mike found he was doing quite well. Helen had quickly undressed to bra and panties, Jackie was done to bra, panties, and pants, and Ray was down to his boxers.
Mike lost the next few hands, with Helen losing one, too. Helen's firm tits held Mike's gaze for an extra second. He felt his erection grow in his boxers. It was Helen's turn to deal. She smiled at Mike, and Jackie lost. Now she was down to bra and panties. Mike compared the two girls. Both were similar, but Helen was a little chubby around her hips. Jackie lost again.
For the first time, Mike saw Jackie's nipples and saw hers were more prominent than his sister's. His hard cock was straining the material in his boxers. Helen lost again. Instead of discretely slipping her panties down, she stood, turned, pulled her panties down over her ass, and slowly down her legs before turning around to show her shaved pussy. Mike almost exploded in his boxers, but somehow managed to contain himself.
Jackie had spotted his situation, winked at Helen, stood up as well, and pulled down her panties. Helen leaned over Mike, her breasts rubbing against his shoulder, and whispered into his ear, "Happy Christmas, Mike, enjoy it with Jackie. I love you."
She walked over to Ray, grabbed his hand, and pulled him onto the sofa. Even before they got there, Ray's boxers were on the floor.
Jackie straddled Mike. She lifted one leg up over Mike's leg and sat facing him. She leaned forward and kissed Mike. His mouth met hers, and he pulled her closer, her firm, hard breasts against his chest. Their kiss intensified, their tongues eagerly meeting. Mike's hands moved down her back and grabbed her ass cheeks. Jackie had one hand on the back of Mike's head. The other was tugging at Mike's boxers. Mike lifted Jackie up enough for her to pull his boxers down, letting his hard cock spring up in the air. Jackie's hand instantly held his throbbing cock. Mike had never felt the feeling of anyone else touching him. The sensation and anticipation were overwhelming, and he suddenly shot his load of cum straight on Jackie's belly.
