As a quick recap, Mark's girlfriend Tiffany is our "dumb slut" of this story. A beautiful 23 year old 5'4" blonde, she loves Mark, but is addicted to attention. Mark, worried she was going to be unfaithful, got some dubious advice from a "sex therapist" to let his friends try and seduce her, all while streaming the experience to Mark so he could make sure she was faithful.
Mark's friend James is the main temptation for Tiffany. He invites her to a house party at his friend's mansion and starts laying on the compliments. Tiffany, meanwhile, is dressed in about as slutty an attire as you could imagine (read Part 1 for a full description). James tempts her, lavishes her with attention, and has finally broken her down; she ended the previous chapter "dancing" with him on her knees, her small skirt hiked up to her belly button, her thong-flossed ass sticking out behind her, and her full DD tits barely held in by a sheer red top. James has dropped his pants, and Tiffany's "dancing" has had his cock slapping her face for a few songs now.
We join back with Tiffany agreeing to repay James with a quick blowjob (but after that, of course nothing else will happen!)
---------------------------------------------------------------------
Tiffany stared forward at James' cock, her red lips lined up with his engorged head. She still hadn't opened them; even with her verbal agreement, something was still uncertain. James' pointed the camera directly down at her, capturing her indecision; she seemed too preoccupied with his dick to notice, or she just didn't care. James' hand rested on the side of her head.
"Tiffany, here, I promise this will be easy. Look up at me, and slowly open your lips. I'll do the rest."
James moved his hand slightly back so his fingers sat at the back of her skull. Her hair fell between his fingers, and he gently put pressure on the back of her head. Tiffany took a breath, her chest swelling. She slowly looked upward, away from James' cock, and her eyes came up to meet his. Her lips began to part, two ruby red lines opening to show a light pink tongue awaiting his presence. With his pressure on her head she began to lean forward, her eyes still on his, her mouth not quite open enough to fit his girth.
His tip touched her bottom lip, and the contact made his cock involuntarily twitch. Tiffany halted, resisting his motion, her eyes not leaving his. She seemed to be waiting for him to insist. Very well; he clenched his fingers, clarifying his intentions, and pulled her mouth forward. Her hands sat on her knees. All of her focus was on the 9" of cock about to enter her mouth.
As his girth separated her lips, her jaw opening to make room, he groaned. Her lips stayed tight on his shaft, but he felt her tongue under his member, the vein that would be delivering his hot load sliding over her smooth, wet surface. Her eyes closed as she accepted him, and she stopped resisting his hand, sliding willingly forward. She stopped as her mouth filled, holding 4" of him. He'd done it.
James groaned. "There you go, you slut. You've got another man's dick in your mouth."
Tiffany moaned to herself, clearly turned on by the attention. She slid back out, a line of drool linking her opening to his tip as she pulled back. "You can't tell him! I'll make you feel good, but don't tell Mark!"
Ironic, as she was surrounded by a circle of horny guys holding phones. She stared up at James.
"Of course, baby. Now let's see what you can do!"
Tiffany brought one hand up to his cock, her small fingers wrapped around the base. She maneuvered her mouth back to his tip and opened wide, this time sticking her tongue out slightly to slide him in. In he went, filling her mouth and tapping the back of her throat, prompting a slight gag. And out, as she slid him back to her entrance, keeping her lips sealed around his tip. Slowly at first, then faster, she sucked. The music pounded, the groups of people chatting and yelling to each other, and Tiffany kept at it.
"My god," thought James, "she is an absolute pro." The suction, the rhythm, the persistence. Nothing fancy yet, but after about a minute of "standard blowjob" James decided to push her a bit.
"Come on, baby. Why don't you show off for me a bit? That body is beautiful and I'd hate to miss it!"
Tiffany opened her eyes and looked up at him, half his dick consumed by her mouth. She paused there, trying to smile, and said "(ghnnhh) yesshhs sshsirrrr (gluccck)".
"Oh my god, she's talking with my cock in her mouth. That's fucking hot."
She took her hand off of her knee and brought it over the top of the fabric covering her right breast. Her mouth popped off of his dick and she stuck her tongue out, wiggling her ass. Slowly she massaged her breast, the pressure causing her mound to swell upward towards James, then back down. Her nipple hardened on her other breast and she groaned seductively, her tongue still stuck out.
"God, you're hot" James said. "What else have you got?"
Tiffany moved her head alongside his cock, then turned her neck to slide her red lips up and down his wet shaft. She began to hum, the vibration almost sending James over the edge. Her eyes closed, then opened as she paused.
"Does this feel good, daddy?"
"God, yes, you fucking slut. You give head like a pro."
Tiffany slid her hand up, then down and under her cup, pushing it downward. Her tit still covered by her soft, small fingers, she rubbed it in time with her hand on James' shaft. The music continued to throb. Her hand slowly lifted off of her breast, her nipple the last thing covered. She tweaked it, showing the full swell of herself, and then released her heavy breast.
One tit out, one hand on his cock, and the other recently freed and resting on his thigh. She began to suck again in earnest.
The next song started and the circle of guys--and a few interested girls--swayed with the music. A few of them had their hands in their pants, stroking themselves while watching her perform. One called out "Great job, keep it up!" to Tiffany, who looked over and smiled, unphased. For the next few minutes she slobbered up and down James' cock, her free breast swaying, some drool beginning to drip from her chin. A steady "(gluck gluck)" accompanied her small fingers stroking the base of his member. James allowed himself to relax and enjoy. Her tongue stroked his vein, her red lips slid up and down, her hair waving forward and back. God, he could do this forever.
James decided it was time to move onto more fun times. He could feel the precum beginning to leak out of his cock. The small crowd around Tiffany stared in amazement as her breast swayed and the sounds of an increasingly sloppy blowjob became louder and louder. The pounding music reverberated through James.
"Tiffany, if you don't stop, I'm going to cum, and I don't think you want that yet. Let's go get a drink at the bar."
Tiffany looked up at him and popped off of his cock. "Really? I mean, yeah, I don't let people cum in my mouth, and you probably shouldn't paint my face at a party. Let's go get a drink."
She stood up, her heels clicking on the dance floor. She finally looked around. The guys stared at her with lustful intention; the girls seemed shocked horny. A few had started dancing together and making out, the scene of James' public pleasure invigorating the crowd. "Oh, all these people were watching?? Shit! Tell them not to tell Mike!"
"Of course, baby. But I'm sure they'd appreciate a little more from you, to make them agree to keep quiet!" James spun her around, his wet cock slapping her ass cheek, and reached his hands under her arms to grab her beautiful tits. She squeaked.
"Here, let's give them a show." And James popped her left tit out to join her right. "To the bar!"
Tiffany walked over, her skirt still not back down to covering the bottom of her thong. Both DD tits stood out over her lacy red "top" (really, more of a bra with some sheer lace underneath). Her stockings still covered her legs up to her knees, and her heels kept her ass round as she walked.
At the bar, the bartender Luke (just one of James' friends who could mix vodka and cranberry juice) looked up. "Damn, James, you seem to be having fun. What will this pretty lady have?" His eyes locked onto Tiffany's two diamond cutter nipples.
