Sex is a Great Full-Body Workout
"Rita, you?"
I tilted my head. Rita had only ever done housework as a maid up until now. She'd never had any reason to pick up a sword. And yet here she was, offering to help me swing one.
"Yes. I watched and learned a little when you used to train in the old days, miss. I can certainly serve as a sparring partner."
"For real?"
"Yes. If you find it hard to believe, I can go outside and show you right now."
She seemed pretty serious about it. There was this passionate determination in her eyes, like she was dead set on teaching me.
"Alright, then. I'll take you up on that."
"Understood."
Irene, who'd been watching us quietly, stood up from her seat.
"Well, looks like you've got a solution sorted out."
"Like I said earlier, it's mostly thanks to you."
"Psh, this is nothing. Train hard, you little bitch Kyle."
That bitch. I wanted to smack her upside the head, but she'd actually helped, so I held back.
"Catch you later. I'm curious if you'll still be a virgin next time we meet~."
"J-just get outta here already…!"
"Good luck!"
Irene climbed into the carriage she'd arrived in, waved at me, and leisurely rode off.
"Now that Miss Irene's gone, shall we train separately?"
"You can do it right now?"
"Yes. I brought some things from the mansion just in case."
Rita headed to the cabin's backyard and opened the shed door. Inside were various items from the mansion—including training wooden swords and even the sword I'd used back when I was a knight.
"Here, catch."
Rita picked up a wooden sword and tossed it to me.
"Nngh…!"
Was a wooden sword always this heavy? I hadn't noticed as a man, but now as a woman, the weight hit me hard. Veins bulged visibly in my wrist.
"Ah, your strength must have weakened after becoming a woman."
"Yeah… this thing feels way heavier than I remember."
"You've fully turned into a female body now, haven't you."
Rita let out a small chuckle, picked up her own wooden sword, and assumed a stance.

"Let's start with a serious go? We need to check how much skill you have left now that you're a woman."
"Sure, let's do it."
To be honest, I didn't expect Rita to be any good with a sword. She'd only ever peeked over my shoulder while I trained—that was it. I hadn't held out much hope.
But then—
Clack!
"…?!"
The sound of wooden swords clashing rang out, and my arm went numb. Rita had blocked my strike head-on. It wasn't just a block. She'd read my sword's trajectory perfectly and countered at the exact right moment with the most efficient angle.
Lucky hit?
I reset my stance and swung quickly at Rita's waist. Not bad speed or angle, considering I'd become a woman.
But again—
Thwack!
"Gh!"
Rita parried it effortlessly.
"Surprised? Because I'm better with a sword than you thought?"
"You learned all this just from watching…?"
"Who do you think I am, miss?"
With that, Rita lowered her stance lightly.
"My turn this time."
Before I could stop her, Rita swung. Her movements were smooth and flexible, yet utterly threatening.
Whoosh!
The elegant arcs her wooden sword traced threatened me relentlessly.
This is seriously…
I barely tracked the tip with my eyes and dodged, but soon I realized it. This was the exact swordsmanship I'd used back in my knight days. And Rita was reproducing it perfectly.
"You need to focus, miss."
"Guh!"
Lost in thought, I took a solid hit from the wooden sword. It hurt. Really hurt. The kind of pain that left a real bruise.
"Rita, you… you could've been a knight and made a fortune with skills like this…."
Rita tapped her wooden sword against her shoulder at my words and spoke.
"Maybe I could have."
"You knew that and still didn't?"
"I told you. I stayed at the mansion because I loved being your maid, and I left with you because I'm your maid."
Rita smiled and continued.
"Above all, I like you too much to ever leave your side."
Hearing that made my heart pound strangely.
Am I crazy?
Has she fucked me so much that I've really turned into a total bitch in heat?
How can you get all fluttery over another woman, Kyle!!
Of course, Rita wasn't exactly a full woman… but officially, she was.
While I was lost in confusion—
Rita approached cautiously and asked,
"Does it hurt a lot?"
"H-huh?"
"The spot you just got hit."
Rita gently touched my side where the wooden sword had struck. A sharp pain shot through me, like a big needle stabbing in.
"Hss…!"
"It must hurt bad. Hold on."
Rita pulled a small herb pouch from her waist. Inside was some ointment she'd clearly made herself.
"Stay still."
Her hand slipped inside my clothes, and soon her ointment-smeared fingers gently rubbed the wound.
"…You're seriously a jack-of-all-trades. Great at housework, swordplay, and making medicine."
"Heh, thanks for the praise."
After rubbing the spot for a bit, Rita chuckled and pulled her hand away.
"No more straining it, or it'll hurt worse. Let's end the sparring here."
Exactly what I wanted. It was already throbbing even while I stood still.
"Yeah, sounds good."
"If you want to train more, how about some stamina building?"
"Stamina training? How?"
Rita's lips curved up at my question. Something felt ominous.
"You don't mean…."
"Hehe…."
"No way…?"
Rita nodded slightly.
"Exactly what you're thinking, miss."
Fuck.
"Haaang!♡ Oh fuck, haa♡ Hoooook!!♡"
In the end, dragged into the cabin by Rita, I was being forcibly fucked.
"S-sex is, haaak!!♡ what, stamina training?!♡"
"What a naive thing to say, miss. Sex is a great full-body workout. Perfect for building stamina."
"If that's true♡ you're the only one, nnghoot♡ moving!!♡"
"If I'm going to spar with you, I need stamina too."
Like you need more stamina, you freak!
…I wanted to say that, but Rita pressed down on my lower belly with her hand, silencing me.
"Hiiiik?!♡"
"And cumming over and over without passing out? That takes stamina too. You'll build it naturally through sex, of course."
"I get it♡ I get, it!♡ So go a little easier, hick♡"
"No way♡"
Paang! Pang!
Rita slammed her cock in deep, shaking her hips hard enough to cut off my words.
"Kgh, haaak!♡ Nngheek♡ Nngooo♡ Hoooook!!♡"
"And the most important reason of all."
Rita leaned down and whispered softly in my ear.
"I just really want to fuck you, miss."
"Y-you, youu♡ Haaak!♡ This was your goal from the start!!♡"
"So what? You're getting revenge, I'm getting your love. Win-win, right?"
I couldn't deny it. Right now, only Rita could spar with me. For revenge, I needed her during that time.
"So just enjoy it. I'm happy right now, thanks to you, ha…."
Squeeze— Rita pressed my lower belly with her hand while thrusting her cock all the way in and whispered,
"I love you, miss."
"Nngheeeuk!!♡"
Pssshhh—!
I came just like that. The pleasure from her hand pressing my womb… my body couldn't resist it anymore.
"Hehe. Things are gonna get busier from now on. Daily stamina training means washing the sheets every morning."
"Nooo♡ Stop, hweek!♡ Sex every day, no way!♡"
"Nngh, nope. Then I won't spar with you."
"Hweeeuk!♡"
Splosh!!
Rita slowly pulled her cock out, then slammed it root-deep in one go. A dizzying wave of pleasure crashed over my mind. My body couldn't resist even once and came again.
"Haaak, haaa♡ Nnghoot, oh…♡"
"Hah, shit… you're so pretty, miss, I'm gonna cum already. Haven't even thrust that much."
Her hips moved faster and faster. Her glans battered my womb relentlessly—the stimulation was maddening.
"Haak!♡ Het, nngheek!♡ Oh fuck, oh♡ Nnghooo♡"
"Take responsibility by catching my cum. My little baby-maker better take every drop properly."
With that, Rita gripped my waist tight to keep me from escaping and thrust to the hilt.
"Oooook!!♡"
"I love you, I love you, miss♡"
Rita's love confession. What followed was the sensation of semen flooding my womb and the overwhelming orgasm it brought.
Bluuuuurgh!!
"He, eek♡ Ugh, haaaak…! Nngho♡ O, ook♡"
Her cock gushed thick cum, filling my womb to the brim—I felt it vividly. My mind went blank white, legs trembling wildly.
"Haa… you really milked it good."
"N-now, that's enough…."
"No way. Stamina doesn't build in one go, right? You have to repeat the workout diligently."
A chill ran down my spine.
That meant, in other words… nonstop sex.
"J-just, Rita… let's think about this a bit, okay?"
"I was tired and wanted to sleep early, but oh well. You want revenge soon, don't you…."
"No. Not right now. Nngheeeuk!!♡"
In the end, stopping Rita was impossible for me… and today, I got fucked like a dog again.
