Open his pants.

Nat's eyes dart from Zack's face to his erection, and she swallows. {if Sluttery < 40}This isn't at all what she meant to do when she sat down here.{if Sluttery > 20} Still...a part of her finds it...sort of tempting.{else} She's feeling, to be blunt, a little panicked.{endif}{else}His cock looks...thick and meaty. A part of her craves it, and she knows it.{endif} She reaches over, hand trembling with {if Virgin = True}fear{elseif Sluttery < 40}nerves{else}eagerness{endif}. He looks so...hard. It can't be comfortable. And this is what girls are for, right? It's what they do. Good girls, at least. She doesn't want to be rude.

"Gooood girl," Zack says with a chuckle as she fumbles at the waistband of his jeans. The praise sends a shiver through her. {if Slut_Clothes=True}He reaches around her shoulder and pulls her closer to him, so that she's pressed right against his side and he can keep mauling her tit with his left hand wrapped around her shoulders. {endif}With his right hand, he reaches down and helps her undo his fly. As she opens his pants, his already-hard cock flops out of the opening in his boxers, waving languidly in the air. Nat lets out a little gasp{if Virgin=True} of shock{elseif Sluttery > 50} of desire{endif}.

"What?" Zack asks, laughing. "It's not like this is the first one you've seen, is it?"

{if Virgin=True}"N-No! Of course not!" Nat stammers, sounding panicked even to herself. She desperately doesn't want this good-looking boy to think she's some stupid little girl. She swallows her fear. I can do this. It's just...just a dick. Just a hard, throbbing cock...full of sticky, warm spunk...that could...could turn me into a dumpslut...{elseif Sluttery < 40}"Uh...no," Nat admits, biting her lip. Zack laughs.{elseif Sluttery > 40}"Mmmmmmm, no," Nat says, also laughing. "{if Slut_Clothes=True}I mean, look at how I'm dressed. {endif}But it is one of the nicer ones..."{endif}

Zack smirks, leaning back in his seat. "Well all right, then. Let's see what you can do, Natalie."

Natalie licks her lips and slowly wraps her hand around his cock. {if Virgin=True}She jumps slightly when it twitches in her palm, which makes him laugh. {endif}It's as tan as he is - maybe a shade lighter - and uncut, the foreskin already starting to peel back as it swells in her hand. She starts to stroke him {if Sluttery > 40}confidently{else}tentatively{endif}, and Zack grunts in satisfaction.

"That's it, {if Slut_Clothes=True}slut{else}Natalie{endif}. Milk me." He bucks his hips slightly and Natalie instinctively tightens her grip, feeling him throb beneath her. {if Virgin = True}Zack's dick is like nothing she's ever felt before. {endif}It's soft yet firm, yielding slightly but with what feels like an iron core. She begins to stroke him more steadily and he groans. "Ooooh yeah, right there. Good girl."

She jerks him off for the next few minutes as the bus rolls along, mesmerized by the way that he continues to respond to her touch. {if Slut_Clothes=True}Zack, for his part, pulls her tank top and bra down, freeing both of her breasts. As she strokes him he kneads her tits, flicking, pinching, and rolling her nipples occasionally and getting gasps of pleasure from Natalie as little electric sparks seem to fly through her body to add to the heat growing in her loins.{elseif Normal_Clothes=True}Zack gropes her breasts idly through her shirt a few times, though once he realizes that she's wearing a bra too he somewhat loses interest.{elseif Prude_Clothes=True}Zack runs his hand up and down her back, rubbing it over her thigh and the outer curve of her ass a couple of times, but mostly relaxes into the handjob and leaves her alone.{endif} Just as she's thinking that they must be most of the way there, he opens his eyes and grins at her.

"{if Virgin=True}You're so cute and timid with your hands!{else}Not bad, not bad{if Slut_Clothes=True}, little slut{endif}.{endif} {if Slut_Clothes=True}But enough of this teasing - come on, get those whore lips on my cock."

His hand rises up to the back of Natalie's head and she feels him suddenly pressing her forcefully downward. He's not really paying attention to whether she responds - he knows a slut dressed like she is, sitting where she did, is going to comply.{else}But there are...y'know...other things I'd be curious to feel..."

His hand rises to her head, stroking her hair for a moment before applying the gentlest pressure to the back of her head, making it clear he'd like her to bend over toward his erection...{endif}
