Green's not giving you a choice in the matter

When you finish wiping your face with a towel you grabbed from your bag, you look up and watch Green recover. The deep breaths she's taking are doing wonderful things to her breasts, the sight of which is making you even harder than you already were.

You're considering whether to relieve your situation or try to ignore it, when Green, having caught her breath, looks down and says, "Well, someone enjoyed getting me off."

You blush a bit, but try to keep your cool. "What can I say, watching a beautiful woman cumming her brains out is pretty hot."

It's Green's turn to blush. "Well, I'm not gonna leave you hanging after that. Lose the pants and get on the couch."

While you stand and almost fall in your hurry to get out of your pants, Green gets on her knees where you were sitting. Taking a seat on the damp couch cushion, you look down and lock eyes with your blushing half-naked friend. Marshaling more willpower than you thought you had, you say, "You, um, don't have to do this. The bet was only for me to get you off."

Green chuckles and shakes her head. "You really are dense, you know that? You're lucky it's kind of cute. Anyway, we've gone way past our little bet by this point,"—she spits on her hands and rubs them together—"at least I hope we have." She grabs your erect member in one hand and gives an experimental pump, sending shivers through your body. "Like I said, I'm kind of into you."

Before you can respond, she renders you incapable of anything but a low moan by lowering her mouth onto your cock, engulfing the head. You can barely think of anything but the pleasure radiating from your groin as she sucks, then begins moving her tongue along the underside of your glans.

Instinctually, you put your hands on the back of her head and push more of your rod into the warm confines of her mouth. When you hit her throat and she gags, you have enough decency and presence of mind to stop and take your hands off of her head.

Green pulls back and catches her breath, then grins up at you, wiping drool from her chin. "Well, someone's feeling bold."

"Sorry, I just—"

"Stop apologizing, I liked it," Green says, with an exasperated look. "Just don't think I'm going to deepthroat you during my first blowjob."

You were pretty certain that you were her first, but actually hearing it brings out some kind of primal feeling of dominance that makes your dick even harder. Seeing this, Green smiles and engulfs it again, this time going as deep as she can without gagging and working the remainder of the shaft with her hand. When she looks up and locks eyes with you, it's almost too much.

As if she can sense you're about to cum and wants to **** you for some reason, she pulls back and releases your cock with a loud pop. "Um, Green, why exactly are you stopping? I'm really close," you say, tempted to reach down and finish the job yourself.

An impish smile appears on Green's face." You didn't think we were stopping here, did you?" Before you can figure out what she means, she makes it clear by unzipping her bag and fishing out a condom.

"You mean..." It hadn't even occurred to you that sex was on the table.

Green carefully tears open the wrapper and explains, "A backroom at school isn't exactly my first choice of places to lose my virginity, but right now it feels right, and more importantly, I'm losing it to you." She's blushing, and not from any of your activities. Not giving you a chance to comment or back out, she gives your cock a few more pumps and rolls the condom on. It's an interesting sensation, but you don't have time to take it in, as Green says, "Alright, get up."

Not willing to take the risk of questioning anything at this point, you stand and watch as Green gets up off her knees and lies down on the couch. She squirms a bit trying to get comfortable, then spreads her legs. Looking up, she blushes and says, "Be gentle, alright?"

"Um, yeah," you manage, taken aback at the sight in front of you. It's hard to reconcile your strong-willed childhood friend with the flushed, **** woman in front of you. Before today you never would have thought of her like this, but now it's hard to imagine anything more natural and right. Not willing or able to wait any longer, you position yourself between her legs and slowly push your aching rod inside her.

She clutches at the couch cushions as you feel yourself press up against a barrier and you pause to look to her for permission to go further. Anxiously biting her lower lip, she nods her assent. As gently as possible, you lower your hips and push through the barrier, hating the look of pain on her face. When you're through, you continue deeper into her until the two of you are completely joined.

Green locks her legs around you and pulls you close, whispering, "Don't move, not yet."

You're actually relieved at her request, as the pressure and warmth surrounding you have you close to exploding. With her so close, you take the opportunity to lean down and kiss her. It's less **** this time; a languid exchange, gentler and more passionate. You take your time enjoying each other, and when you finally part, you brush a stray lock of hair from her face and ask, "Ready?"

A familiar grin forms on her face and she nods. With much more of her usual energy and attitude, she says, "Oh, yeah. Let's do this."

You lean down and place one last quick kiss on her lips, then carefully pull back and thrust into her. You withdraw slowly again, but are pulled in hard and fast by Green's legs.

"I said I was ready," she says impatiently, "Get to it!"

Not inclined to argue, you pull back again and slam into her, eliciting a pleasant yelp from the bossy brunette. Pleased with her response and enjoying the sensation yourself, you continue to increase your pace. Before long, the two of you are grunting and moaning like pokémon. Green's legs pull you in with each thrust, her hands clawing at your back as her breasts bounce wildly between you.

"Almost... there... don't... stop..." she moans haltingly with each thrust, tightening around you.

"Me too," you pant, the increased pressure pushing you past your limit. "Cumming!"

Green lets out a wordless cry as you release your load into the rubber, her pussy spasming wildly on your still ejaculating member. She meets you halfway as you lean down to capture her lips, the two of you sharing a passionate kiss until both your orgasms have passed.

As the heat of the moment passes, an awkward air fills the room. You lift yourself up off of Green and pull out, tying off the condom and tossing it into a trash bin, while Green sits up and begins to straighten herself and pull down her clothes, neither of you looking at each other. You know that the two of you need to have a conversation after everything that's happened, but you have no idea what to say.
