"Oo-o-oh fuck! Fuck! AH!" David's body spasmed as he succumbed to orgasm. It felt better than he thought, but then so far, everything about being a woman had felt better than he thought.
Between David's legs, Ryan slowed and then eventually stopped what he was doing with his mouth. Ryan smiled up at David, who just laid there, gasping. "Told you I could make you cum."
"Goddamnit man, fine! You win the bet! I can't believe I have to stay like this for almost three days now!" David whined.
David and Ryan had found a spellbook. David had tested it out first, transforming Ryan into a cat. The spells didn't last long - about six hours. The spellbook was clear there were ways to make the spells last longer - notably, having an orgasm made the duration increase by a factor of ten.
After Ryan turned back, David had teased him about being a "pussy". For his turn with the book, Ryan gave David a pussy all his own. Ryan had just laughed, talking about how hot he was as a woman. When Ryan wagered a thousand bucks he could make David cum, David had been confident it was easy money. What did Ryan know about getting off girls?
Quite a lot, apparently. Now David would be sitting down to pee for the next few days...

Two and a half days later
=====
David had mostly spent the past few days staying at home. It was a mixed bag because every time he'd look down at his own tits he'd get turned on and there was nothing to distract him. Much as he wanted to do something about that feeling, he was still under the spell, and another orgasm would make the duration go up by a factor of ten again.
Desperate for something to take him mind off his arousal, when Ryan asked if David wanted to get lunch at the mall, Ryan agreed. After a quick mall food court lunch, Ryan said he needed to do some shopping. David was still looking for distraction and agreed to come along.
They wandered into a half-dead department store to an aisle way in the back when Ryan realized it hadn't been a friendly invitation. With one swift move, Ryan exposed David's pussy and shoved his fingers inside.
"Ryan! What the fuck!" David gasped as Ryan's fingers started to thrust.
"You were squirming like a horny slut all lunch. Your pussy is soaking wet!" Ryan grinned.
"Ah!" David moaned. Ryan's fingers felt heavenly, but still - "Stop! You can't just- we're in public!" David whispered hoarsely, "OOOnnMmghh! Stop! You're going to make me-"
When the orgasm hit him, David nearly collapsed into a simpering wet mess. Only Ryan's firm grip on his crotch kept him on his feet.
When he finally came down and Ryan's fingers slipped out of him, David stood bolt upright and slapped Ryan's face. "You fucker! You made me cum again! Shit, what's six hundred hours!?"
"You loved it." Ryan rubbed his cheek, smiling.
David stomped away from Ryan, cursing and trying to do the math in his head. By the time he'd gotten back to his car, he'd figured out six hundred hours was almost four weeks...
=====
Three and a half weeks later
=====
David was sitting at home, brooding. The past few weeks had been - well they hadn't been easy. He mostly did gig work on the internet, so had mostly been able to continue working. The harder part was after work when he didn't have anything to do other than sit around and think about his incredibly hot body and get turned on. More than a few times he'd caught himself unconsciously humping something - the arm of a chair, the corner of a table, the washing machine - trying to get some relief. When he realized what he was doing, in an act of herculean willpower, he'd stop himself.
Ryan kept texting David, but David refused to see him. Ryan insisted it was all just a joke, and if David could see his o-face, he'd get why Ryan had done it.
Towards the end of three weeks, David was starting to feel a little more willing to hear his old friend out. He agreed to a video call - one last chance to let his buddy see the body he'd never get to touch again.
"You're still super hot." Ryan said on the call, and David grinned. Maybe he'd give Ryan blue balls. "Will you at least admit you enjoyed it?"
"You mean having to sit to pee for almost a month - or the fact that I can't reach anything on my top shelves anymore?" David rolled his eyes. He knew exactly what Ryan meant and decided there was a chance to get in a little more teasing. "Or you mean these tits?" David popped open his shirt, giving Ryan a good look at his bra and tits.
"I don't just mean those tits." Ryan was practically drooling on vid. "I mean the whole thing. Those orgasms especially. I've never heard a girl cum like that outside of a porno!"
David sighed and smiled a little. He couldn't even pretend they hadn't been some of the best orgasms of his life. "They were awesome, but I'm not letting you get your hands near me to give me another."
Ryan smirked, "That's fine. There's actually a spell in here that will do it for me. leef flesuoy llews dna moolb ni eht thgieh fo doohnamow! Leef sregnif dna eugnot ssorca ruoy..."
"What is-" David gasped as an intense pleasure appeared out of nowhere in his crotch as Ryan continued chanting the spellbook's words. It was like Ryan's fingers and tongue combined at once - but multiplied and overlapping! "AH! FUCK!" David shouted. "Ryan! Please! MMNNGH! Stop! OH GOD! I'm gonna- not- AGAIN!"
It was by far the most intense of all the orgasms David had had so far. Weeks of pent-up arousal would do that.
When it was done, David was left there, slumped in his chair and breathing heavily. Ryan was still on the line, smiling at him. "You dick." David said weekly. In his head he was trying to do the math. Six thousand hours...
"It's about eight months." Ryan was beaming a smile, "Or, you know, forever, since I doubt you'll be able to go that long without cumming again."
"Fuck." David grumbled. He was sure Ryan was right. Three plus weeks had been hard enough. And after an orgasm like that? Hell, half of him just wanted to ask Ryan to use that spell again right then and there. "Why?"
"Remember when you said you wanted to date my sister, and I told you not to, then you did anyways, and then you dumped her and made her cry? Remember how you asked me if I was cool with it and I said 'no', but you just ignored me and a week later called to see if I wanted to play video games? Well, this all started as revenge for that. Then... well, you just make a better woman than a man. You admitted you liked it. And you're just so damn hot!"
"So you just ruined my whole fucking life because of that?!" David shouted. "I'm just some nameless woman now!"
"No, that would be cruel." Ryan said. "There's another spell in here that makes it so everybody but you and me will think you were always a woman. I figured I'd give that spell a cast... once you do me a solid."
"And what exactly is that?" David asked.
=====
One hour later
=====
"Fuck, fuck, fuck!" David grunted as he bounced on Ryan's cock. The worst fucking part was despite how pissed he was at Ryan, it still felt really good.
Another orgasm hit and David could almost feel the time stretching out. Eighty months. Six years. There was no way he wasn't doing this again though, and the next time... well it would be a lifetime with no going back.
=====
Months later
=====
People would later remark about how a tension emerged between "Day" and Ryan all of a sudden. More than a few thought they must've tried to date and it had gone sour. Despite the tension, they still ran in similar circles, so they saw each other from time to time. Despite Day's newfound disdain for Ryan, more than a few of their mutual friends suspected the two of them did some hate-fucking from time to time...
They weren't wrong.
