Exercise before bed

For years, your bed had only ever been occupied by you and you alone.

But starting from tonight, that was going to change.

"Mmmgh, hnng..."

You looked down upon your bed with a wide smirk across your face.

Right after Tsunade came in, you grabbed her and restrained her with the same accessories you had acquired from the hospital.

Now bound, gagged, and blindfolded once more, Tsunade trembled on her knees.

She turned to face you, even though she couldn't see anything behind the blindfold.

"Don't worry."

Your hand brushed over one side of her tushy.

Tsunade flinched from the touch and let out a small whimper that was barely audible.

"I'll be gentle...since it's your first day."

You lined up your cock and gently pushed forward.

"Hnnngfh...!!"

Tsunade twitched and shuddered as your phallus made its way inside her.

'Oh, fuck... is, is this how it's supposed to feel like?'

A low growl escaped your throat.

You could feel the moist walls squeeze around your cock, enveloping it in a sensation you couldn't replicate while masturbating.

After a few seconds, you began to move your hips back and forth.

"Hnngh, engfh...!"

At first, you moved slowly.

Not because you particularly cared about your partner's safety or anything like that; it was just that the sensation took some time to get used to.

Not long after, your confidence began building up.

"Ennph! Hngfh!! Gnghf!!"

You moved faster, slapping your thighs into Tsunade's wide hips to drive your cock deep inside her.

Tsunade's moan became more rapid and high-pitched.

Her head moved back as a constant wave of pleasure stimulated her brain, as nothing else had before.

In the spur of the moment, you grabbed a handful of her blonde hair and yanked it back.

"Erepmh!!"

Tsunade let out a yelp akin to a neighing horse.

That made you chuckle.

"You like that, huh?"

You gave Tsunade a few more tugs, drawing out some more groans from your gagged fuck toy.

You kept your grip on her hair until it strained your arm.

"Fuck, fuck...!"

By then, you could feel the end was near.

Your balls churned with fresh semen. Your heart pounded as if you had been running a mile.

"Fuck, I'm going to cum...!!"

You thrust in for one last time, reaching Tsunade's vagina as you broke the limit.

Splurt! Slpurt!!

"Mmmmph!!"

Tsunade let out a howl as her climax hit like a chemical reaction as soon as her master's cum poured into her pussy.

"Oooohhh..."

Even after you were done ejaculating, you slowly pumped back and forth a few more times before finally pulling out.

"Hffpphh...gnngg..."

Tsunade mumbled into her gag.

Drool dribbled down from the edges of her mouth while cum poured out like a small waterfall from her pussy.

Your cock, coated with fluid from both sides, rested on her ass.

"That was fun."

You reached out and pulled off Tsunade's blindfold and ball gag.

"Haaahh..."

Tsunade breathed out loud as soon as her mouth was free.

You decided that this was enough for one night.

It was the first night, after all.

You didn't want to play out all the cards too soon and get bored with the one toy you were allowed to have.

So you flopped down onto the bed with a relaxed sigh.

Tsunade tensed up when your arms went around her waist from behind.

She hiccuped when you slid your cock between her thick thighs, smearing the mixture of fluids against her skin.

"M, master...?"

"I said I'm going easy on you for the first day.

I'm going to sleep now... don't wake me up until there's breakfast ready."

You couldn't see Tsunade's expression, but something told you that she wasn't happy about your words.

Unfortunately for her, you didn't give two cents about what she thought.

You buried your face into Tsunade's hair, which surprisingly smelled nice, and closed your eyes, falling into a pleasant world of dreams.

You couldn't wait for tomorrow to come.
