Jess starts to strip for Chris

As you watched this, your hand went unconsciously down to your crotch and started to lightly rub your hard-on. You could tell the head of your cock was covered in pre-cum. Your mouth was dry. You still felt the need to put a stop to this though. "But he had a hard-on before. Isn't it pressing up against your ass now?" you asked Jess, trying hard to make it sound like this was very upsetting to you.

"Mmm, yeah, I guess it is," Jess said, wiggling her ass as if to confirm this fact. "But, I mean, I've had his fat cock completely inside me like a million times, so this is, like, nothing. Just don't worry about it, baby."

You swallowed hard and said, "Ok, I guess it's fine..." She smiled, and started moving her ass up and down against Chris's body, clearly rubbing up against his cock. Your hand wrapped more firmly around your erection through your sweatpants, and you could see Jess watching you do this. She looked you in the eyes and smirked at you. It felt like a line had just been crossed.

"That's a good boy. This is all just totally innocent, baby," Jess said. Then she shrugged a little and one of the straps on her tanktop fell off her shoulder. She looked down at Chris's and said, "Oops."

"Oops," Chris's repeated as he reached up and pulled her tanktop down, completely revealing one of her breasts. He started massaging her tit right in front of you, then leaned over and flicked her nipple with his tongue, looking directly at you. "Remember, just a little innocent flirting," he said, then started sucking on her tit. Jess let out a loud moan and pressed herself back against him. "God damn, your girl has such perfect fucking tits, bro," he said, not even looking at you.

"What the fuck..." I said softly, loosening your grip on your cock to keep yourself from cumming.

Chris's lifted Jess's tanktop completely over her head so that she was only in her running shorts, then ran his hands all over her. They started making out. You couldn't believe this was happening, but you had also never been so completely turned on.

"Why don't you do a little innocent flirting with my dick?" Chris's asked, moving Jess to one leg so that he could pull his cock out through the slit in his boxers.

"Mmmm. Look, John, doesn't he just have the most beautiful cock?" Jess asked as her fingers wrapped around it.

You unconsciously licked your lips and, without even realizing what you were saying, groaned, "Mmhmm." They looked at you, then at each other, and laughed. You realized now what you had just said and felt yourself turning red. But you also looked back at Chris's cock, escaping through his boxers underneath that amazingly hard body of his, and licked your lips again. What the fuck was going on? You were getting turned on by another guy? You'd never felt like this before, but you were too turned on to think about it too much.

Jess rubbed his cock up and down with her hand while they made out, Chris's hands moving between squeezing her tits and her ass.

After a little while of this, you completely gave up and pulled your cock out of your sweatpants, openly stroking yourself. Chris's stopped and looked over at you. "Hey, man, since you're being so cool about all this, I feel a little bad that you aren't getting to participate a little bit. Why don't you come over and take Jess's shorts off so that I can see what panties she's wearing?"

You gulped, put your cock back in your sweatpants, and said, "Uh, yeah, ok. Thanks, man."

"No problem, buddy," Chris's said, then, to Jess, "Babe, stand up here in front of me so I can get a good look." He positioned her so that she was directly facing him, then he sat back in the couch and stroked his cock. You were still sitting in your chair watching, so he looked over at you and said, a little impatiently, "Come on, man, let's go."

You got up and stepped over to Jess, then got down on your knees so that you could pull her shorts down. Chris's cock was inches from your face, and you couldn't help but stare as he wagged the giant thing at you, smirking. You **** yourself to look away, and reached up to Jess's shorts, slowly pulling them down. She was wearing a lacy purple thong that you had bought her for her birthday.
