Nothing. There’s nothing you can do

You watch nervously as the Keltraxan presses on the electronics on his chest and starts talking again.

“Day 3. I have stopped observing and decided to try a more direct approach with the humans. Here are my first impressions: the male apparently is aware of my presence. He now stands upright, probably trying to intimidate me by appearing taller and bigger. The female, instead, leaves me perplexed: she is looking in my direction; however, it does not appear she knows I am here. She still stands on all fours, although the male has stopped mating with her.”

You realize that the Keltraxan is right: you are still on all fours, the last sex juices coming out of your body. Dammit, you are now a zoo animal and get to be watched every time you and Toby mate, but surely now is not the time for sex. You still have limits!

You get up on your feet. Slowly, carefully, not putting too much weight on one foot, because all the lovemaking with Toby has taken a heavy toll: you are almost unable to walk. At least for a while.

The Keltraxan watches as you get on your feet and withdraw towards Toby . You can feel Toby's hands on your shoulders, his head a few inches behind you and his cock stiffening again, feeling your pussy is near. You however are not in the mood for sex right now.

“Wait. The female is now standing upright too. She is obviously conscious of my presence. She appears to look for security in her mating partner. From what I’ve seen so far, human females are pretty harmless and need a male for protection.”

“I’ll show you how harmless I am, you…”

But before you can even move a foot in the direction of the Keltraxan, or try to attack him, you hear a zap. The next second you are back on the floor, groaning in pain and trying to recover from the terrible shock that has passed through your body.

For a second, you do not remember. Then you do.

Your hands move to your neck, and you find an old acquaintance of yours around it.

“Hello again, zap collar” you mutter to yourself.

Toby himself has his one back. However, it appears like this time the collars are a bit different. You start watching closely and you realize: they are now tagged. Apparently, the Keltraxans have decided to rename you and Toby like you would have done with a pet. The only upside is that you cannot read it, so you will never know what kind of name the Keltraxans have given you.

“The female has tried to walk in my direction, but the zap collar has stopped her before she could move. I do not know if she was intentionally aggressive, or if the collar interpreted something harmless as dangerous. Starting close examination now”

The Keltraxan comes closer, and you feel your collar starting to activate again. However, this time it's not an electric shock, but some kind of magnetic wave that makes you feel more relaxed. It takes you a moment to realize why: to keep you in a passive state, while the Keltraxan does what he wants.

You try to resist, but it is futile: in a few minutes, your own arms and legs are no longer responding to the commands of your brain anymore, and you go back lying on the floor, your body’s adrenalin neutralized by the alien’s technology.

“Following the procedures” says the Keltraxan starting to touch your body “According to my measurements, the female has great capacity of breeding, so it’s better to keep her undressed. I can see that her reproductive organs are now becoming bigger, which indicates that the addictive substance the zookeepers put into their food is effective.”

The Keltraxan rolls you on your side and starts touching your breast. His touch is not like Toby's : more invasive, and less beautiful.

“According from what I’ve seen in the last few days, these parts are human udders. The females are able to secrete a white nutritive fluid, which I think is probably used to feed their offspring from the moment they give birth. I am now taking a sample”

Even with your mind in a semi-comatose state, you can see him taking a strange object from his bag and putting it over your right breast. What is he trying to…

Oh. The machine starts to light up and flash, and you feel pleasure trough your chest again. The sensation this thing does is similar to Toby's tongue licking your nipples. However, this is not love: this is artificial.

You feel an itching sensation before you realize that your breasts are now secreting milk, the left over the grass, the right one into the machine. The thing beeps, before shutting off.

Then the Keltraxan removes it from your body, and puts it back into his bag.

“Very well. I have a good example of human nutritional liquid for the laboratory. Can you please change the effect of the collar from “tranquilize” to “sleep”? I now will have to do some internal check-up, and it is better if the specimen does not react.”

The collar starts to pulse, and the world around you turns black.
