Join them.

You enter the office, not entirely sure what you've let yourself in for, and Belinda closes the door behind you.

Leo suddenly grabs her in front of the desk and starts pawing her breasts and biting her neck. Belinda squeals, but doesn't object. "Damn, you smell good, Belinda," Leo says. "Are you wearing some new perfume your Daddy invented or something?"

"I think it's just that Parker's got me so horny," Belinda pants as her shirt comes up over her breasts.

"Or it's Parker herself rubbing off on you," Leo responds. "I know she smelled just as good when she was in her cheerleader outfit sucking me off." Leo looks over at you standing awkwardly by the door. "Why don't you come join you're girlfriend here Parker?"

You move over next to Belinda and join in as the two of them rapidly start moving clothes aside until Leo has his pants around his ankles. Belinda slides down to her knees in front of him with her shirt up, her tits out, and her skirt bunched at her waist. She shoves a hand into her panties and uses her other hand to guide Leo's cock to her mouth.

Leo rests his hands on top of Belinda's head while she tenderly licks his cock and balls. He looks over at you and gives you a grin. "You can join in any time here, Parker," he says.

Belinda slowly and deliberately takes his cock into her mouth and moves her head up and down on it slowly, all the while staring into your eyes. Then she takes it out of her mouth with a pop and aims it towards you.

As you watch her do this, you feel a very peculiar mixture of jealousy and lust. Without realizing it you've closed the distance to Leo's cock and closed your mouth around it. You can taste Belinda's spit and Leo's pre-cum. Leo's hands begins guiding your head up and down like Belinda's had been just a moment ago.

After a few minutes, during which your blowjob gets progressively faster and Leo's lust becomes obviously more and more acute, Leo lifts your head up and pulls out of your mouth. Grabbing Belinda by the arm he pulls her to her feet. He pulls her around to the other side of the desk, hobbling a bit with his pants around his ankles, and bends her over it so that both of them are looking right at you. He then pushes her skirt all the way up and pulls her panties down to her knees. You watch Belinda's eyes and mouth both get wider as Leo penetrates her. She tightly closes her eyes, groans, and shakes a little, making you fairly certain she's having an orgasm.

Leo thrusts into her throughout her orgasm though you note with some surprise that he's using short, shallow thrusts and is almost gentle. He certainly wasn't that gentle with you.

When Belinda stops shaking, Leo starts slowly accelerating his thrusts and her eyes open wide again. As soon as her eyes manage to focus, she stares into your eyes and licks her lips as her body rocks back and forth. Leo starts fucking her faster and faster while Belinda vocally expresses her pleasure by yelping louder and louder. Then Belinda's eyes close tight as she reaches a loud orgasm.

Leo pulls out of her and Belinda turns and kneels in front of him. He motions to you to move beside her once again and begins stroking his cock. Belinda kisses you quickly as you take your place and then looks up again as Leo begins to groan. His cum begins shooting towards your upturned faces and you instinctively open your mouth. He grabs your head and shoves his cock in, finishing the rest of his load on your tongue. Once he finishes he pulls out and you swallow it down.

Belinda takes his cock into her mouth and licks him clean. Then she pulls his pants up for him and even zips him up. She adjusts her own clothes, gives him a hug, and says, "Thanks, Leo." Then she walks over to you and licks up a drop of cum that missed your mouth. She reeks of sweat and sex and you realize that you must as well. "Thanks, Parker. That was great."

Leo walks over to you and says, "Yeah, thanks, Parker! Belinda's a hell of a catch. Don't let anyone tell you otherwise." He walks out of the room and Belinda says, "Shall we head home?"

You agree and, after quickly cleaning up and re-dressing the two of you head to the exit.
