Because we were pressed so tightly together, his movements were smaller, but the force was just as strong as usual or even stronger.
It truly felt like he was savoring every single part of me, and that excitement was transmitting straight to me.
Since his face was right next to mine, I could hear every heavy breath and every word he muttered involuntarily.
His thick cock pistoned steadily in and out of my soaking pussy, the raw friction and heat making my inner walls clench and flutter around him with every deep thrust, grinding against my g-spot and bumping my cervix repeatedly.
Being groped and toyed with under the clothes… there was no slick lotion feel, but it somehow reminded me of a strange lotion play… and it was quite arousing.
Plus, I actually don’t dislike the smell of a man’s sweat… at least during sex.
…However, this method of fucking had one very big — in fact, fatal — drawback.
It was extremely simple… …It’s hot.
No, that’s it.
It’s insanely, unbearably hot.
Of course it is.
It’s midsummer, in a room with no air conditioning, wearing a long-sleeved, long-pants tracksuit!
On top of that, we’re doing something that already makes you sweat and drains your stamina — sex!
There’s no way this wouldn’t be hot!
In fact, if I’m not imagining it… my body has gone beyond “hot” and is now “burning”!?
Wait, could this be heatstroke…?
“Haa… haa… Uwah, incredible… Sis’s inside… it’s so much hotter than usual…!” Ah, you feel it too?
…So I really am on the verge of heatstroke…?
Wait, is this seriously dangerous!?
N-now that I think about it, after finishing the window cleaning and coming back inside, did I even rehydrate?
I did chug a glass of water, so I thought I had taken in enough fluids… (…Maybe not…) Fun fact: When humans sweat, they lose not only water but also salt and other minerals.
That’s why after sweating, it’s better to drink sports drinks or mineral-rich barley tea rather than plain water.
Otherwise, the water (and minerals) can end up flushing out even more, making dehydration worse.
But when I came back, Yuichi had already finished all the barley tea, and there were no sports drinks left… so I had no choice but to drink tap water… Eh, am I actually in real trouble?
Somehow… my head feels dizzy…?
I’ve never felt like this while pretending to sleep before…!?
So this really is… While I was thinking that, Yuichi hugged me even tighter, pressing his body — including his face and neck — firmly against mine.
So hot, so burning hot!
“Amazing, Sis… you smell so good…!” He hugged me tighter while taking deep breaths.
The hand groping my breasts moved more aggressively.
Is this guy trying to kill me!?
“Sis’s inside is twitching so much… it feels so good…” Convulsions!?
Is my body seriously okay!?
The heat kept rising, combined with Yuichi’s body temperature, and the tracksuit trapped all the heat so it couldn’t escape.
His cock continued plunging deep into my pussy, the intense heat making every thrust feel even more overwhelming as my walls rippled and squeezed around his throbbing length.
Just when I seriously started considering dropping the “pretend sleep” act… Yuichi began thrusting his hips even more violently.
I immediately understood what that meant.
The next moment, something far hotter than the summer heat or body temperature scorched my insides as he unleashed a massive load of cum deep into my pussy, flooding my womb with thick, pulsing ropes of hot semen.
Even in this heat, I could still clearly feel the heat of his semen… My body reacted honestly.
With a violent full-body shudder, I climaxed from the long-awaited sensation in every sense of the word.
My pussy spasmed wildly around his cock, milking every drop as powerful waves of ecstasy crashed through me.
Throb, throb… I felt Yuichi’s cock pulsing even harder than usual… and finally, satisfied, he pulled away from me.
Probably because there wasn’t much time, there was no second or third round.
Thank goodness.
Then, as always, he cleaned up afterward… and left the room.
…He’s gone, right?
Okay, no one’s here anymore?
It’s safe to wake up now?
No sound?
…Alright.
“It felt good but it was disgusting!!” I sprang up instantly.
Within two seconds I ripped off the tracksuit, becoming completely naked.
I grabbed a round fan in my right hand and fanned myself with all my strength while holding a small handheld fan in my left, blowing air all over my body to cool down.
Ah, the wind on my sweaty skin feels so good… I was sticky with sweat all over and wanted to jump into the bath immediately, but first I needed to cool my body and clear my head or I might collapse on the way.
It was that hot.
I fanned my face, stomach, back, cleavage, and between my legs without shame.
Who cares if it’s indecent?
I didn’t have the luxury to worry about that.
After fanning myself for a while, the heat finally started to subside.
But I could clearly feel my body craving fluids… any more and I’d really dehydrate.
I should rehydrate before getting in the bath or it might be dangerous.
…There should be some oral rehydration solution in the emergency supplies stored downstairs.
The serious one Dad renews every year.
Sorry, but I’m taking it.
Actually, I’m the victim of a disaster right now — a man-made one.
So it’s fine.
I’ll just buy a replacement later and put it back.
Today’s lesson: Make sure to rehydrate properly before having sex (sleep sex) on a hot day.
…A lesson that probably won’t have many chances to be used.
By the way, after this incident, I decided to avoid creating sleep-sex opportunities on hot summer days, especially during the daytime… but for a while afterward, I kept feeling Yuichi’s gaze searching for chances.
…Did he really like the sweaty play that much?
