Busted - And a Challenge

Mark laughs at his sisters, saying “Hey man, I don’t care if you two wanna fuck - get your rocks off.” Addison and Kayleigh breathe a sigh of relief, and Kimberly says “Damn girls, I thought you two liked boys - not that it matters. You guys do you!” and laughs a little. “We DO like boys!” Addison tells her, and Mark states “Well that would explain the dildo.” Kayleigh tells him to shut up as he laughs, and Kimberly says “Kayleigh I know you broke up with Kirk awhile ago, and Addison you broke up with Parker - if you two want to get laid, why don’t you just check things off the slut list?” The sisters look at her and both say almost in unison, “What’s the slut list?”

Kimberly tosses her long, light brown hair out of her face and laughs. “The slut list is a list of sexual activities for girls. More like a contest, really. You work your way through the list and each thing is worth a certain number of points, and at the end of the agreed upon time whoever has the most points wins.” “You mean whoever has the most points is the biggest slut,” Mark laughs. “And how exactly do you know about this list anyway, DEAR?” he asks Kimberly, teasingly. She rolls her eyes and says “I never said I played it, asshole. It was something some sorority girls came up with, which is exactly why I didn’t join one.”

“So what’s on the list?” Kayleigh asks. “Honestly I’m not totally sure, I heard some pledges talking about it a couple of years ago and wasn’t interested. I COULD try and find it, you know, if you two WANTED me to,” Kimberly says with a twinkle in her green eyes. Addison and Kayleigh whisper to each other - neither is certain they want to have a sex contest and be sluts, but neither wants to waste all this time with their parents gone and not have any sex at all either. After a few minutes Mark says “Oh my god, just fucking do it you two! Who cares what anyone might think!”and they both excitedly agree. Kimberly says, “OK, lemme grab my phone and hunt around for it. Be right back.” and goes to grab her phone. She returns a few minutes later and says “OK, I found it,” and texts a copy of it to Addison and Kayleigh. The three girls look over the list, sometimes laughing and giggling, at other times shocked at what it could entail.

After a half hour or so, the two sisters agree to try to do as many things on the list as they can, and then Kayleigh asks “But how will we know if the other one has done something? I mean, I could just go into a locker room alone and say I fucked half the team but really didn’t.” Kimberly says, “Hmm, yeah, that’s a good point. Well, I guess you would need some sort of proof.” Addison, looking through the list, says, “Ah, OK, I think I know how we can do this. But it’s gonna take both of us.” She and Kayleigh talk for a few minutes and come up with a plan. Kimberly, smiling at the two sisters, says “Good. I like your idea. Have fun girls. For the same sex and threesome items, it probably shouldn’t count if it’s the two of you - the whole point is to be a slut by fucking other, new people, not anyone you’ve already been with. Oh, and one more thing - this is a three-way contest. I’m going to challenge both of you. Good luck, girls.” She grabs Mark’s hand and walks with him back to the bedroom, leaving Addison and Kayleigh stunned and giggling.

“What the fuck, Kim! You want to be a fucking slut now and fuck a bunch of guys?!” Mark yells. “Yes I do, and you are going to watch every second of it,” she replies. “After all, YOU’RE the one who is always talking about watching me with other men. And now I’m going to do it.” Mark stares silently at the floor for a few minutes before asking “So you really want to do this, then? I mean, yeah it’s been a fantasy of mine, but I never thought you would want to do it . . .” Kimberly smiles at him, replying “Yes, I want to do it. And not just for you . . . Mark, I love you. But if this is going to work we need to communicate openly. You have done that with me - now I’m doing it with you.” Mark kisses her, and says “Alright then. Go have fun.” Kimberly laughs and responds, “Oh, I know I will!” Just then her phone dings with a message. “Who is it?” asks Mark. “It’s the girls. They’re wondering if I’m playing the game or not, and if so they want an extra point for . . . SECURING proof of completion of their first task, and they also suggest that one extra point be given if the guy is a black man.” Kimberly says as she types a response and hits “Send.” “What did you say?” he asks. She smiles at him and says “I told them ‘Game on. Good luck!’” The lovers laugh and Kimberly crouches down and yanks off Mark’s underwear, then jams his dick in her mouth.
