Note: this story involves cheating and cuckolding.
The following night, Jenny and Simon were sitting together on his couch watching TV. "Hey, baby?" Jenny asked him.
"Yeah, sweetie?" Simon asked.
"Um...I've been thinking about doing something that might make our sex life a little more...exciting," she said.
"Oh, yeah?" Simon asked, intrigued.
"Mmhmmm," she said, rubbing his thigh. She heard his breathing get faster and knew he was already getting worked up. She moved her hand up a little higher and started rubbing his crotch through his jeans. "You know my friend Katie?" Katie was Jenny's junior friend who had told her all about Brad. They hung out from time to time, and Jenny had noticed Simon's eyes practically popping out of his head when he looked at her. It made sense, she was a very sexy redhead.
"Uh, yeah" Simon said, not sure where this was going, but clearly enjoying Jenny's hand rubbing his crotch.
"Well, I know you think she's hot, right?" Jenny asked him.
"Ohh...uh...well, I mean, sure, she's very pretty," Simon said, his voice getting a little shaky as he got more excited.
Jenny leaned in and spoke softly into his ear, rubbing his crotch more quickly. "Well...so, I was thinking...maybe we could...have a threesome?"
"Ohhhhhhh fuck," Simon whimpered. Jenny could feel him squirting into his underwear already and couldn't help but giggle. He turned red and said, "Shit, I'm sorry, honey."
"It's okay, sweetie," Jenny said. "You know I'm used to it. So...I guess you like the idea?"
"Uh, well, yeah, that sounds amazing," Simon said.
"Well, good," Jenny said. "The only thing is..." She hesitated.
Simon took her hand. "What is it, baby?"
"Well," Jenny said. "I just feel like, if you get to have a threesome with me and another girl, it's only fair if I get to have a threesome with you and another guy."
Simon looked surprised. "Oh...um...well..."
Jenny looked sad and started to act guilty. "Oh, I'm sorry, honey, I shouldn't have even asked, that was so stupid of me, I'm sorry."
Now Simon felt bad. "No, no, don't apologize," Simon said quickly. "I mean, you're right. It's, um, only fair. Did you, like, have somebody in mind?"
"Um, well...I know it sounds weird, but I think I'd only feel comfortable doing something crazy like a threesome with somebody I already know, just like I'm already friends with Katie," Jenny said.
"Oh," Simon said. "Like who?"
"Well," Jenny said, "you know how my ex-boyfriend Mark goes here?"
"Your ex-boyfriend from high school?" Simon asked. "You...you want to have a threesome with him?"
Jenny pretended to act embarrassed. "I mean, not if it's too weird for you. I'm sorry, baby, I should never have brought this up."
She knew this act would make Simon feel guilty and cave in to her completely. He was so sweet that way. "No, no, it's okay," he said. "I just...it's not like you still have feelings for him or anything, right?"
"No, of course not, baby," Jenny said comfortingly. "I've told you before, he was a real jerk. It's just, you know, I feel comfortable with him...physically."
"Oh," Simon said. "Uh, yeah, well...that's okay, I guess."
"Are you sure?" she asked.
"Um, yeah," Simon said. "I mean, like you said, it's only fair, if I get to have a threesome with you and Katie."
Jenny smiled and gave him a big hug. "You're the best boyfriend in the world," she said.

The next day, Jenny invited Katie over for the threesome. Katie was bisexual and had enthusiastically agreed, excited by the opportunity to have fun with her hot frreshman girlfriend. When Simon came over to Jenny's place after class, he found her and Katie making out in the bedroom in just their panties.
"Oh, wow, uh, hi," he stammered, amazed at the sight.
"Hi, baby," Jenny said. "I hope you don't mind we got started a little early."
"Not at all," Simon said with a grin.
"Hi, Simon," Katie said, smiling and patting the bed. "Your girlfriend's a great kisser. Why don't you come join us?"
Simon quickly dropped his backpack and started stripping down to his underwear. His erection strained against his white briefs as he crawled into bed between these two hot girls. The girls cuddled up on either side of him, rubbing his chest and moaning excitedly. Jenny leaned in and made out with Simon, then turned Simon's head in Katie's direction so they could make out.
"Mmm," Simon said, clearly enjoying himself. He briefly parted lips with Katie and asked Jenny, "Are you sure you're okay with this, honey?"
"Oh, yeah, baby, it's hot," Jenny said encouragingly. Then she leaned over and began making out with Katie herself, reaching behind her to undo her bra. Katie undid Jenny's bra, and Simon watched in awe as the two girls felt each other up and made out in front of him. Then Katie pulled Simon's briefs down so that his erection popped out. Jenny looked at Katie. "Care to join me down here?" she asked.
