She likes it, a LOT

As you came down the stairs Crystal looked up at you and her eyes widened, her previous smirk completely wiped from her face. Her eyes trailed up your legs to the edge of the dress, so short that even your small package almost peaked through the bottom.
"I'm ready Crystal" you say in your best seductive voice, which didn't really work since you're so nervous and had never tried "seductive" before, but since Crystal was still just eyeing you up you figured it was fine.
"Wow" she finally said, before finally remembering herself. "I didn't think you'd go this far Doug, but now you've made a problem." Before you could really worry about what problem you had caused she had already answered, pulling down her jeans to reveal her hard 12 inch cock. "Dougie there's no way I can go out like this." she said lightly shaking it, your's eyes watching as if hypnotized.
She didn't even get a chance to say anything else before you stepped forward, throwing her extra height into stark relief. "I can take care of it" you said, getting ready to drop to his knees. You've never sucked cock before, never really wanted to either, but with Crystal right there you were more then eager to do anything, and everything.
Before you can though Crystal stops you "You've never had a real kiss before have you?" She asked lightly, still focusing on her cock you weren't really paying attention as you shook your head no. "That's a shame, as much as I want you sucking right now, I can't let you go without a kiss first."
Still paying more attention to her cock then her words you are caught completely off guard when she suddenly grabs the back of your head pulling you into a kiss, shoving her tongue into your mouth.

Eyes rolling up you immediately decided it was all worth this, the diary, the panic, getting ready, everything just for that kiss, she could do whatever she wanted with you now you were happy.
And do what she wanted is exactly what she did as she began to press downwards on you, pushing you to your knees, you happily went your struck dumb expression from the kiss remaining.
"Suck" was all she said as you got face-to-face with her massive cock.

So suck you did, you have no technique or experience, but you do have a lot of enthusiasm, as you crammed as much of the cock into your mouth and throat as you possibly can on the first go, ****, before retreating and doing it again. Messy and loud your only goal was to get as much of the dick into your throat as you can and make her cum.
"Oh shit Doug" Crystal wasn't prepared for that at all, far more experienced then you but never had she even seen a boy be so eager, making some of the noisiest **** noises she had ever heard even in porno's, spit everywhere. Not the most skilled blowjob she had every gotten, not by a long shot, but by far the best.
"Hrgg, grcckkk, shcolck" you were **** but keep going, getting another inch in, and another, until after nearly 5 minutes, spit all over your face, massacre running, you get all 12 inches into your throat. Still you didn't slow down slamming yourself against her groin as you just kept going, up and down, in and out.
Crystal couldn't take it anymore, it had been years since she had come from less then 10 minutes of sucking but she was blowing the load of her life "FUCK I'M COMING SWALLOW IT ALL BABY!!!!!!" she screamed at the top of her lungs, grabbing your head and forcing it down, holding it, as pleasure took you, orgasming yourself.
"GULP GULP GULP" you swallowed, and swallowed, and swallowed, you were about to pass out but just kept swallowing until she lets go, falling onto your back coughing.
After a minute of just taking it in Crystal finally looks at you, still on the ground just panting, and she saw something she wasn't expecting at all, from the bottom of your dress, thin and much more water-like then any girl's cum, but without a doubt was cum, dripping down your legs. You had cum from that vicious throat-fucking.
"Oh Doug I love you" she said breathless, just to quite for you to hear, still in your own ****, cumming, world.

Now what to do next thought the girl, she had to get Doug up she was in no way done with him, but then what? Clean him up, or maybe skip the dinner and just go fuck him, or she could follow trough and take him to a fancy dinner, she'd pay and everything. Of course if she did that she couldn't let him wash up, so he'd look like a whore that just got choked out, but that was part of the fun, showing his devotion to her, and afterwards she'd really have to fuck him extra hard for all the waiting.
