Test Subject #001: Gabriel Grayson

Gabriel has shown tremendous growth since last week, currently his penis stands at 7 inches with a diameter (girth) of 1.22 inches, when he he began at 5.8 inches and 1.08 diameter. His balls have also grown slightly but they are difficult to achieve measurements on. Right now they are slightly larger than two Apricots.

Sperm production is up, semen loads are thicker and whiter, but we are yet again unsure of why. Masturbation has increased, daily masturbation has increased to at least two times per day.

As for me, a growth has appeared about and inch above my clitoris, it currently is a soft, tumoresque growth that is very spongy and sticks out about an inch. Tests have shown the cells of the growth are reproductive stem cells. We are cutting the growth off today.

The growth above my clitoris has been successfuly removed three times now. However it keeps growing, even after using every antibiotic we have, it keeps growing. I am concerned, for now, updates may stagnate as research now is now time based.

The growth has not been discourage by continued cutting, it is like a plant. You prune it and it sinply wants to grow faster. For now, me and the team have decided to stop cutting it, currently it stands at around three inches with a diameter of 0.69 there is now feeling in the growth, I am concerned for myself.

As for Gabriel, he has grown another inch, but progress seems to be slowing, especially for his diameter, which has sat at a 1.50 for about three days.

Things have been crazy here, infighting has caused everyone to question the research we're conducting, especially the ethics of it. And especially with me, as even though I'm affected, I'm not a test subject, and continued tests of the draintrap itself and Gabriel have left us with nothing except hearing the sounds of pleasure echo in the air.

Gabriel has stopped growth at 10 inches and 1.50 diamenter.

I however, have not stopped growing. Right now, the growth on me is undoubtedly a human penis, and growth has been tremendous, noticeable by the day. my growth sits at 5 inches and 1.29 diameter. I don't think it will stop soon.

The team has disbanded, our research is over. However, myy research, is not over. Suffice to say, when I saw Gabriel like that the first time, and then the rest, over and over I was fascinated. Clearly nobody saw potential in him before, I mean, he was desperate enough to become our guinea pig, via some compensation of course... But, I wondered what if felt like, to be came in for nearly half a minute... It must be—flling.

However when my growth stopped, I wondered something else... At 7 inches with my huge diameter... Could I? No I couldn't possibly imagine getting penetrated like that.

...

Oh but I can imagine it, the sounding I've done before, imagine if the rod was throbbing, and hot, and moved on its own volition. And that rod... It belonged to him, Gabriel.

I hear a knock on the door

!!! It's him, I see him through the peephole

I open the door

"Hi Dr. Sorna, I came here to see you because the last time we met it wasn't very... pleasent everybody was yelling at eachother"

"Oh- thanks so much for stopping by, would you like a cup of tea?"

"Oh no thank you, I didn't plan-"

Here's where my plan comes in

"Well come in anyway sweetheart"

He walks in, shuts, and locks the door behind him. I gesture him to sit down on the corner of the dinner table and I sit parallel to him.

"So what did you want to say to me handsome?" Gabriel is still blushing from the last name call, now he's practically red.

"Oh, I, ah, wanted to just say thank you for having me on the team. And of course having you as the one to watch me was... Great!"

"And why's that?"

"Well the other two researchers uhm-"

"They weren't... girls?"

"I... okay... yeah..."

I reach for his right hand with mine and he doesn't pull back, I put it on the table and start caressing it gently.

I look into his eyes

"Doctor..."

"Shhhhh shh sh... You don't need to call me doctor, be quiet"

...

With my left hand I reach towards his groin, and feel something very firm.

"Are you happy to see me? Just say the eord and I'll stop"

"...I'm very happy to see you"

"Good."

I stand up and drag him to the bedroom, I shut and lock the door. I stare into his eyes, he stares back but as I unbotton my shirt and pants he loses focus on my eyes and notices something bigger staring at him.

"Eliza... when did you get so big?"

"It stopped growing a little bit ago, but see the size? It's all for you"

His eyes light up, we share the same idea

We get on the bed in missionary, erect. I lube our dicks so nothing bad happens when he gets inside me. We hold our hands together, he aligns himself and pushes in.

He slowly, slowly inserts, his dick into mine, stopping with steady thrusts right at the tip. It's like nothing I've ever felt, the warmth of his tip inside mine... it's incredible. And the anticipation that I've held for so long about this, it makes me feel all the sensations so much stronger, he pushes deeper allwhile still teasing my tip halfway down my shaft I get this feeling that I haven't got before, one in my balls that grew on me. It must be nothing, but I'm wrong, as he thrusts in the halfway point I writhe in my position, throw my head up a few times.

"Are you okay?"

"I'm about... to cum"

I reach the point of no return, my balls start contracting and I release, I've never came like this in my life, yet it made me feel so empty, I came and came and came, and before I came Gabriel shoved in slightly deeper. I noticed Gabriel's balls getting larger as I came, I think my cum entered him...

He kept thrusting, making sure to check on me periodically, to see if I'm alright, to see if it's too much, god he's so cute, he's such a sweetheart. He thrusts deeper and deepr reaching my base

"Go all the way"

"I don't want to hurt you"

"Deeper. Deep."

He thrusts all the way into my dick, past my base and past it all, it feels amazing, fuck.

"Eliza I'm getting close"

This is what I've been waiting for, the feeling of being full!

"I'm really close again too"

He keeps thrusting, deep, so deep. The throbbing from his dick makes the sensations traveling so much better than traditional sounding, he's alive, I'm alive we're we're we're reaching the peak

"Let's cum at the same time!"

With his command I hold, and I hold but it's not enough, the floodgates are open. Cum spurts from around the seal he has on my shaft, but most of it goes into him, liquids from my proper reproductives shoot out onto the bed... Wait, he's sending it all back to me!

I make sounds I didn't even know were possible, it feels so good being pumped! Gabriel spurts into my shaft, load after load, my balls go from the size of apricots to tangerines. He spurts again, tangerines to lemons, again! Grapefruits again! small footballs.

He switches from my penis to my pussy, holding it in as he switches and he fills me up well, my belly stretches and swells greatly before he lets out one final breath and pulls out, leaving cum to dribble onto the bed.

We breathe for a moment, but only a moment, as our bodies relax he lays down next to me

"I had... a lot of fun"

"me too"

He leans in and kisses me, tired as we both are, we cuddled up and fall asleep.

Just before I fall unconscious a thought bubbles into my brain... Oh my god... We never figured out what was going on with his balls, why they were so... so... so... I'm so tired.

In my sleep I can feel my balls churning and churning, they didn't want him, they wanted me, they wanted him to fuck me so they could get to their home, to where they belong. In order to reproduce, oh godd... What have I done?

Hope you all enjoyed this part! I was debating putting the plant flair on this because the plant hasn't actually shown up in a while, but all this was started from a plant and the next part will include them so I think it's fair!

The Draintrap (Part 2)

I have a lot of ideas for this series, I have a little roadmap planned in my head and I think you all will love it!

To the team, It has been about two weeks since our test concluded. Gordon was sick, so I had to run the machines, I made the recording stop at six minutes instead of log for six and keep recording, my mistake.

During these last two weeks we have discovered: Several side effects in Gabriel, a new type of plant, and the trumpet's purpose. We also have a new theory regarding this plant.

We have learned new details of the plant via our tests, one being that nearly all parts of the trumpet are meant for stimulation purposes, except for the inner lip, which is meant to hold onto the tip of a shaft in order to lock a victim in place, harming the victim if it dares to pull out.

As for side effects, we've spotted many concerning things with our guinea pig Gabriel, who has been a good test subject all this time. First of all, right after the test he said his penis doesn't feel right, he described it as a "subtle pulsing" strange, but as it turns out that the inflammation from his election was permanent, and it continued. Since April 22nd, Gabriel has grown an ⅙ of an inch in size and 0.11 inches in girth. Which may not seem like a lot, but is astonishing to see first hand~... After our discovery on the 23rd, we collected data on length and girth measurements and the trend seems to be somewhat exponential.

Secondly, Gabriel claims he has experienced heightened levels of "horniness" brain scans we performed indicated the Amygdala being more active than our his control scan, he also has an elevated body temperature of 0.06 degrees.

Thirdly, he claims that his genitals feel "off" and that he feels like sometimes they feel like they are churning, we performed as many tests as we can, even collected a sample of his semen, but we couldn't identify anything wrong—we are slightly concerned.

Finally, and the most concerning factor, everytime Gabriel ejaculates it isn't regular, it's as if he was on the plant. AKA, Gabriel ejaculates until there's nothing left in him, and even then his body makes sure there's nothing left, and he heaves even when he's ejaculating nothing.

We are worried for the wellbeing of Gabriel, however not only did he agree to anything of the unknown that could happen, he also claims that everything that's happening is fine, to him, he gets a bigger penis and everytime he masturbates the pleasure lasts very long, I don't think it's a fair trade, but he does.

A new discovery was made, the pistil has a hole in it, it is quite small, which is how it flew under the radar the first few times, but it makes me wonder, what if this hole has something to do with Gabriel's genitals? What if something entered him this way? But everything points to no, there was nothing in the semen sample, no evidence from the scan, and he hasn't said anything other than "they feel off, like churning" it's perplexing.

A seperate research team has begun working on the new type of plant, however, they informed me of a wild location if I was interested, their claim was that "It was like the draintrap, but for females" while I wasn't interested at first, certain thoughts churned in my head.

REPORT

I'm writing this report in the aftermath of my experience with what I'll be calling "The venus draintrap" in homage to it's original counterpart. The venus draintrap is exactly like the original, except it has two twin flowers, these flowers also have a trumpet shape, but unfurl as a potential victim (me) gets closer, I won't be submitting the audio recording as it would make me feel uncomfortable, especially if the rest of the team had to hear it. When the flowers are unfurled, it almost looks like a cornstalk with corn inside, the pistil is bumpy, long, and quite large in size. The secondary one was smaller, above the first one, it also had a hole in the middle of it. They were drooped to the side and my perfect height, I couldn't resist. I was in a slightly awkward starting squat position, but it felt incredible. It felt alive, almost like a human, it felt amazing but I still had to work for it, ramming into the pistil over and over again, like nothing else mattered. This was undoubtedly due to the powder, but... I still feel it a little bit. During my climax however, when I was off my guard, I felt a needle poke above my clitoris and when I reared back, the top pistil had a needle slowly retracting back into the plant, what was I stabbed with?

END REPORT

I hope you all enjoyed this as much as the first one, I know there isn't much to exactly jerk to on this one but, I do need this part to provide background as to what will cum next (which is very exciting!!) Sorry for any writing errors, these are usually made at night and the morning after I wake up. I was considering making a poll so YOU! Guys could change the direction a little bit but I'm not sure, I'll have to hear you guys out.
