Volunteering for a doctor because you were bored. Getting to wear that cute little nurse dress and follow the doctor around. Having to travel hours for a facility that's on high lock down. Talks about how some of his best experiments are there. He is so excited to have new eyes see his work. Getting there and the place actually looks amazing. It's clean, up to date, and staff are nice. Patients are excelling amazingly thanks to him and you get to document/help.
Until you get to the last level of the place. The doctor is the only one with access. Telling you that most of his other volunteers don't usually get that far. Concerned but you just nod and keep following him deeper. Until you get to a room he promises this patient looks rough but he's nice. Opening the door and you see a beast of a man, almost literally. The doctor explains that he was an experiment with animal DNA or something messed up. You're shocked because the ones upstairs aren't as gone as him.
It's messed up but it's not like you can report it. Whoever the guy is read the paperwork he signed himself up for this. You help the doctor do the regular routines but the guy is hyper focused on you. The doctor notices your tense behavior and laughs, he likes you. The doctor coos softly, you know he's been behaving so well as of late. He's had so many setbacks... I'm proud of how hard he's trying. The doctor finished up the regular check up and sighs, why don't we give him a treat? He looks at you and nods so being a stupid little thing you nod along with him.
Nice to see you agree, the doctor smirks. Stand there, he takes a couple steps back and looks at the man beast. Have your treat, suddenly you're being tackled to the ground. You let out a loud scream as you struggle against him but it's a big fail. He's way too strong and too damn big. Dress rising as a hand literally rips your panties off. It's been a while since he's had a treat so he's excited, the doctor walks back over. He looks down at you as you struggle against the man beast. Before you can curse him out your being stretched open. Another cry leaves your lips as you tense up and shake. You've never taken anything so big and he's so animalistic about it.
I'll give you something to help with any pain after, the doctor kneels down casually as the man beast fucks into you. Quick and hard pure instinct and need. You're having a hard time thinking and even breathing as you get fucked. The man growling and huffing as his hips keep moving. I'll also need to collect the sperm that he'll push into you, the doctor softly moves hair from your face. It will be good research material, see if that animal DNA has really affected everything. The doctor keeps talking casually as his experiment keeps using you. The doctor tries to touch your cunt but the man growls and pulls you closer. Making you take his length completely and you let out a strained cry. Easy! Behave! I'm not taking your treat away, the doctor scolds and goes back to checking your cunt.
Looks like you've done an excellent job at stretching around him. His base is even flaring up...he has a knot...amazing, the doctor gasps. All you can do is whine as you feel the orgasm coming. You are the best volunteer! If you can take his knot...I'll hire you permanently, this...this will be amazing to study! The doctor stands up and rushed to get his camera, the one he documents experiment updates on. He starts recording you getting used by the experiment. It's incredible! He's performing human-like breeding positions but everything else is animalistic. He circles around you both while recording before kneeling back down.
You weakly try to cover your face from the camera but you can't do anything right. The way your body is getting used and the orgasm that's being pushed through it, has you gone. Did you just cum? The doctor gasps when you let out another squeal. She's taken the knot... This is just fascinating, he knew when to take his chance. Her body accommodated it too, the doctor is high off of theories and amazement. He's fucking it in and out of her...poor girl will need so much care after. He's swelling even more..and he's locked in. The man beast lets out a loud moan as he cums in you. Your shaking feeling way too full.
Release, suddenly the man beast holds you tighter. You're done with your treat, I said release! He doesn't wanna let you go and growls at the doctor. Possessive... I'll need to do more experiments... Fine, well wait for the knot to go down then it's back to your room. The doctor turns his camera off and stands up. You my dear...have earned yourself a permanent spot on my team.
