It was a crisp Saturday night. There was another party. Jennie Finch had been hitting the party scene fairly hard. She spotted her friend Betsy, her "big sister."
"Hey, Jennie," said Betsy warmly.
"Hey, Betsy. What's up?"
"Well, Jack and I have been talking."
"How's it going?"
"Well, that's why I wanted to talk to you tonight," Betsy said. "Jack and I have been together a while and we like to try new things."
"Yeah, you have to," Jennie said. "Don't want things to get stale."
"So that's where you come in," Betsy said.
"I don't get it."
"Well, Jack and I have decided to have a threesome."
"Cool."
"We want you to be the third. I know how good you are, and I know you think Jack is hot, so we both agreed you should be the third."
"You want me to what?"
"Join us. Fill out our threesome."
Jennie blushed. The surprise on her face was palpable. "Uh, what?" she said.
"Come on, Jennie," Betsy said. "It will be fun." Betsy backed Jennie against a wall. She grabbed Jennie's crotch and planted a hard, wet kiss on Jennie. "I can tell you're interested," Betsy said. She blew in Jennie's ear.
"God, Betsy," Jennie said. "I don't know if I can handle this." Betsy kissed her again. Jennie sighed.
"It will be fun," Betsy whispered. Jennie grabbed Betsy's round ass. She pulled Betsy to her. Again they kissed. Betsy ran her tongue around Jennie's mouth. Jennie fondled Betsy's boobs.
Jennie took a big, deep breath. "OK," she said. She sighed. She wasn't sure she was ready for this, but Betsy was her friend and she was so insistent. She gulped.
"OK, let's do it."
Jennie and Betsy held hands as they climbed the stairs to Betsy's room. They entered. Jack was sitting in the chair, waiting.
"It's a go," Betsy said. "It didn't take too much persuasion." Betsy smiled. She turned to find Jennie already naked.
"If we're doing this thing, let's do it," Jennie said with a nervous smile. She walked over and sat on Jack's lap. She unzipped his pants. Jack whipped his shirt off. Meanwhile, Betsy stripped down to her sheer lingerie. As Jack finished getting naked, Betsy tapped Jennie on the shoulder.
Betsy wrapped her arms around the tall blonde and fondled her ample, naked tits. She began to kiss Jennie's naked back.
"God, Betsy," Jennie sighed. She turned around and kissed her friend. She groped Betsy's crotch. She undid Betsy's bra. Quickly, Betsy's underwear came off.
"So now that we're all naked..." Betsy said. She sat on her boyfriend's lap. She began to dance. Jennie grabbed her and fondled her boobs. She kissed Betsy's neck. Betsy continued to bounce on Jack's lap.
