Sexual experiment (1/2) +18

Tsunade was currently in her observation room which was separated from her testing room by a wall of glass.

On the other side, which was the testing room with various equipment for testing, a bed was added for this time's test.

Inside of this room, Ren and Sakura were getting ready to start performing the test Tsunade wanted.

She sighed to herself as she felt somewhat weird about all that was going on currently.

'But, what's done is done already…'

She didn't want to do it this way or do it in the first place, but she can't lie to herself all the time. Her interest in Ren was just too great and becoming even bigger by the second as she watched him through the glass taking off his clothes.

There was a reason she had told Ren about a date after all since she was very interested in him.

Or more aptly said, she was interested in what the sex was like with what Sakura was dubbing a sex god.

But she wasn't that easy to get into bed with.

Despite how she was acting, that was just arousal acting, but in reality, she would never get with a guy, at least until she gets to know him well.

'And I do know about Ren slightly…'

She had come to know him for a while now through the chatroom they were members of, but it wasn't enough to base a relationship on.

So, if she wanted to get to know him well, to finally taste the spectacular forbidden fruit that is sex with him, then the date was the first step.

'And he'll have to do more than just attract me for that to work…'

She chuckled to herself for a bit and then continued on watching Ren undress.

'It's certainly a sight to behold…'

Her legs rubbed together as she tried hard to hold her professionalism while watching.

Her panties were soaked already, and if not for her mental endurance, she would have stormed the testing room, switched places with Sakura, and done the deed with Ren.

But, the date comes first…

**********

Ren took off his shirt easily, and he stretched his arms around a bit before he started to take on his pants.

*Beep*

"Uhm, hey… cough, Sakura can you get to it already…"

As Ren took off his pants, he heard this voice through the speaker.

He turned to look at the mirror glass that was showing his and Sakura's reflection, and he knew Tsunade was on the other side. The glass can become see-through by the press of a button, but Tsunade had turned it off the moment she had entered inside.

'Who knows what she is doing there…?'

Ren smiled to himself as even though her voice he knew she was very aroused just from watching him strip.

Right now, he was just in his boxers.

And he decided to let Sakura take the last piece for a visual show for Tsunade.

But as he turned to see her, she was crouching behind a small table and hiding herself.

He laughed as he then knew why Tsunade had called her.

'This girl…'

Ren shook his head at her.

Although he was fine being watched, he had asked her if she agreed to Tsunade, and she nodded and even whispered that it excited her a lot.

But now that it was about to start, she was acting this way.

He went nearby her and wanted to once again ask if she was okay with this, as he can cut off any deal or agreement they had.

But before he even went one step forward, Tsunade's voice rang out again.

"Sakura, you don't have to agree to my selfish desire you know? You can refuse if you're uncomfortable,"

Her voice was caring. And it was something she really meant.

And Sakura knew that.

She wasn't being forced by pressure or anything like that.

*Sigh*

'It's just… the faces I would undoubtedly be making later on… I-I can't look master in the eyes after…'

She would be very embarrassed at that time.

This was what was preventing her. But after a bit, she finally took a deep breath and stopped hiding herself.

"I'm good now,"

"But, master please don't record us or anything,"

Sakura knew they had cameras on, and while she was okay with her master, she didn't want other people to see her, and that was a strong possibility.

Why? Because this was the hero world, and even if Tsunade didn't share that, hackers existed.

Tsunade snorted.

"Who's the master here, me or you?" I know that more than you.

She just chuckled as she joked.

"But, relax, I'm not stupid, you too Ren, this is just for my eyes, the cams are all off"

She assured them.

And then with a final sigh, Sakura took off her clothes. Including underwear, unlike Ren.

Both people watching her had already seen her naked, but Sakura nonetheless turned excited even more.

She couldn't control herself anymore.

What with being horny and all.

She dove at Ren's legs and took off his boxers with one motion.

**********

*Gulp*

"Is that… supposed to be normal?"

Right before Tsunade's eyes, Ren's towering cock was reflected.

It was nothing like she was expecting.

Despite Sakura repeatedly telling her his cock was big, she wasn't able to picture it was by this much.

"This should be possible naturally of course, but it is very rare and has special circumstances which makes me think it is a byproduct of his trait…"

She analyzed calmly and arrived at this conjuncture, but while she was speaking professionally, her body was reacting differently.

She was bushing madly, as her eyes couldn't leave his cock. Despite his whole body being attractive to her, at this moment she could only stare at his cock intently.

As she was sitting on her chair, it wasn't visible what was happening under the table that had the controls and was situated below the glass.

But… she was currently rubbing her legs together while in heat, and one had was sitting in between doing who knows what…

She had the cams off, and the glass hid her figure as it acted as a mirror to Ren and Sakura, and she even had the audio off, until she presses a button and then her voice would be heard.

"Since his trait is of highly effective sexual attraction, it is only natural that my attraction to him would heighten as he became naked,"

She nodded to herself and scribbled some notes with her unoccupied hand.

As she took her eyes for one second off them, she felt such unwillingness, and then she decided to not write, but rather record her voice.

She brought the recorder and started speaking into it while she watched them.

"It appears Sakura is also entranced, as she hungrily observes his cock…"

"A sort of highly sexual atmosphere seems to be present in the room, and Sakura immediately went toward the cock… most likely she had missed it since the last time,"

"Seeing her do so, the same desire started to become apparent in me,"

"…"

"…"

She kept speaking into the recorder, and she didn't take her eyes off the two people engaging sexually.

She didn't even hide her own feelings, as this will all be reviewed by her later on for further study.

But now, she saw Sakura take Ren's clothes off, and then sniff his cock while intoxicated by the smell.

Tsunade observed how Sakura was acting at this moment.

Sakura then started to play with the cock as the two started talking with each other as they enjoyed themselves.

She took the whole cock inside of her mouth, and Tsunade saw his cock disappear inch by inch inside of Sakura's throat.

Meanwhile, Sakura swallowed it and started to twirl her tongue around it, and started to slide up and down the length of the cock, slobbering it up and even helping by jerking it off with her hands.

It was almost like she was… worshipping it.

And Tsunade was documenting it all by her voice recording.

Though as she was watching that, her desire was exploding, and it became harder and harder to stop herself from jumping at them, either joining them or just taking Ren for herself.

She noticed that when she had that thought, her mind would become so foggy from her arousal and excitement.

Finally, after a bit of play like that, Ren grabbed Sakura's head and raised her gently.

He then grabbed her waist and back for support before he flipped her easily, doing a 6x9 in the air. Her thighs were around his neck, and her face was just on his cock.

This new pose was documented by Tsunade, with all the new emotions it induced, and she observed even her own that resulted.

Sakura then attacked his cock as if she knew her role in the matter already, and Ren started eating her out similarly.

She sucked his cock, pretty much like she had done before, except this time the cock hit at an angle that made it push further in and bring a new feeling to Sakura.

'The upper of his cock was touching the upper of her mouth earlier… but now it is touching the lower part of her mouth instead'

'At this angle, it should be easier to touch and penetrate her throat, and that must be the reason that the spit is visible whenever she takes his cock in and out now,'

She analyzed very rapidly, and despite her increasing arousal, and being very horny, her mind still managed to think about that.

Her hand though was very busy pleasuring her under the table, and it was starting to become suffocating slightly from the heat, so she had already opened the windows for her tits to breathe. Ergo, took off her bra.

After a while of her watching them pleasure each other, she was very close to cum herself.

And at the same time as her, it seemed like Ren was about to cum or was very close to, as he supported Sakura in that position with one hand, and he used his other hand to grab Sakura's head before he started to thrust into her throat himself.

This brought Tsunade's arousal a step further and very soon she came and started shuddering as the vision of Sakura's throat bulging entered her eyes, and the bulge was even further than when it did when Ren's cock entered her throat before.

She heard Sakura moaning out loud, from the climax that Tsunade was dying to have a taste of, and Ren's cum dripped out of Sakura's mouth as she couldn't take it all.

Tsunade rode her orgasm, as she made a mental note to record this later, since now she couldn't even move her hand much less do so.
