Tony's a fast learner.

"...I think so," Tony finally manages to wheeze out. He's pretty sure he came a little too quickly, but it wasn't as if he'd had much practice beyond the occasional drunk fling in college (and then he'd rarely had to worry about performance considering how buzzed he and his date might be). Still, Katie's smile let him know that even if there was definite room for improvement she wouldn't hold it against him.

"I knew you would, Tony."

He stands there in a daze for a few more seconds before shrugging off the afterglow and returns to the matter at hand. He stares down at Katie's shrinking member and bites a lip. In the back of his mind, there's part of him that's still confused about how to react to all this. It'd been hot in the moment when Katie had been servicing herself but now the old mental blockades seemed to be forming again.

"If I, uh, don't do this, maybe I'll never be able to. Gotta rip that band aid off."

Katie leans back against the couch, spreading her legs and inviting him inwards. Kneeling in front of her, he finds himself face to face with her massive tool. He gulps and butterflies begin to dance in his stomach and, with a free hand, he reaches out to grasp her. Her dick immediately stiffens at the contact and Katie lets out a slight hiss somewhere above him. It's warm to the touch and just as solid as Tony imagined it would be. Pausing for a moment he weighed his options.

On the one hand, a hand job wouldn't be that challenging; all he'd have to do was watch how fast he was stroking her. On the other, returning a blow job was probably only fair all things considered. Still, the more Tony looked at the anaconda in front of him the more he doubted his ability to fit her in his mouth (a sentence he was still trying to process) in a satisfying way. She's a foot long now that he has her hot and bothered.

"Take your time," Katie says quietly, her voice easing at least some of the fear that's beginning to well in him. "Just relax."

His eyes drift downwards to her ball sack and he has to marvel at the size of the testicles within it. They're easily the size of the kinds of premium eggs anyone would be able to pick up in a grocery store and he's more than certain that her orgasm earlier had been restrained. If he could really get her going... well, he was sure that the money shot would make any porn director proud.

Angling her penis away from him, Tony moved his head down to meet the scrotum. The scent of strawberries and cream greeted his nostrils, the body wash Katie always loved to wear, and even with the sight before him Tony had to admit that it was oddly comforting. His girlfriend was, in the end, the same person he'd left behind. It was then, too, that he made up his mind about what he was going to do.

Not all lessons could be taught in school, after all.

He opened his mouth and gently let his tongue begin to move against the bottom of Katie's sack, the baby soft skin feeling surprisingly pleasant against the organ. He moved up the scrotum, letting his tongue swirl against each of her nuts in a circular motion. Tony's perhaps most surprised at the texture of her testicles, firm but yet soft enough not to feel unpleasant. To his girlfriend's credit, aside from a slight twitch she's staying the course for letting him experiment.

That all changes, though, as Tony opens up his jaw and begins to suck on one of her balls. Katie's shaft instantly becomes rock solid as Tony's lips press against the object and he almost loses control of it as he moves his head slightly back and forth.

"Oh fuck, oh fuck," Katie says through clenched teeth.

He lets the first go for a moment, then moves his mouth to the second, repeating the process. Katie's back is ram rod straight against the sofa, thrusting her hips out to him as far as she's able to, eyes closed. Tony has to admit that doing all of this is much easier than he thought it'd be. Perhaps without Katie he'd have never been able to make the leap but watching her dark aureola harden and listening to her breathy whimpering almost makes up for how upset he'd felt earlier today. Maybe he'd been all wrong; maybe the parts didn't matter so long as it all belonged to Katie.

When he finally feels satisfied at the massage he's given her, Tony lets her scrotum fall from his mouth. Her penis is firm in his grasp, almost unyielding to the pressure he uses as he tries to angle it towards him better. This is the moment of truth, he thinks to himself. Backing out now isn't an option, not at this point given what he's done with Katie. Taking a deep breath, closing his eyes, Tony begins to work from the base of her 'root,' dragging his tongue along her immense length. It feels like it takes ages as he sits there, looking up at her as he moves from the bottom of her penis to the top, letting saliva trail after him run down past his chin. When he finally reaches her tip, the first thing he's greeted with is the precum that's begin to bubble out of her. Just as everyone said it did, Tony isn't surprised to learn that the taste that greets him can only be described as 'salty.' It's not revolting like he'd thought it might be but it's definitely strange as the liquid splashes its way into him.

"Y-you s-s-sure you ha-haven't d-done this b-b-before?" Katie asks, biting her lower lip. He wordlessly shakes his head, not wanting to interrupt the rhythm that he's managed to find himself.

Taking a moment to pull back Tony takes stock of the situation. Working his way up on Katie had only proven just how daunting this whole affair was going to be. Even if he'd wanted to there was no way he could fit Katie's entire womanhood into him. Perhaps, with a little more training, he'd be able to get pretty far down on her but that wasn't going to be today. He licks her head again, running his tongue over her pinkness. He'd fantasized a lot when he was younger about giving Katie oral but he'd never imagined it would turn out quite like this.

When he finally does open his mouth, careful not to let his teeth rake against her, he has to admit that the repetitive sensation is almost soothing. Katie's foreskin moves back and forth, gently tickling his lips as he carefully deep throats his girlfriend. Looking up, he can see that his girlfriend's mouth is split into an ear to ear smile, silently mouthing an 'O' as he works her. Tony isn't sure whether or not he'll ever prefer this to eating a woman out. It's far too early to tell and it almost makes him feel homesick in absurd way, but the fact Katie is enjoying herself only makes him pick up his pace and the only sounds which fill his apartment are the squelching of his busywork and Katie's ecstasy.

It's almost a compliment that she doesn't give him a warning she's close to the edge. At some point Katie finally reaches her breaking point and it all comes spilling forth, her balls emptying what feels like gallons of sperm into him as he quickly removes himself from her and pulls back, gagging slightly as she continues to hit him even after he's disengaged, the new cum dripping down his chest and onto the floor to join what she'd already unleashed. He pants, swallowing what remains of her load, as he leans against one of the cushions adjacent to her for support.

"Thank you, Tony," Katie whispers. "That was... wow."

"I had a great teacher," Tony says, giving her a playful smirk. "Just maybe let me know next time when you're getting ready to drown me."

She doesn't even respond to his snark as she wipes some of the sweat that's formed on her brow away. Opening her eyes again, she lets out a playful smile and leans forward.

"How about another lesson then?"

She nudges him away and Tony scoots back from the couch as she lowers herself onto the carpet. He says nothing, waiting for her to continue.

"I'd... I'd like for you to make me a woman, Tony," Katie says, a blush spreading across her face.

"O-oh," Tony says, his own face beginning to redden.

Katie lowers herself onto all fours, lowering her upper body and raising her rear to him, baring her perfectly toned ass and sculpted legs to him. She moves back and forth, dick and balls swaying with the movement.

"Don't be scared. I'm on the pill; you won't have to worry about getting me pregnant."
