Wait and playing along

You stay seated on the bed, thinking that you must play along if you want to survive and escape.
Three nurses enter the room, one of them holds a strange device with a ruler, tapping it lightly against her palm, while another carries some notes. The third holds what looks like a collar.

"Let’s not make this harder than it has to be" the nurse with the device.
They surround you. One nurse grips your arm (she's extremely strong, but you don't resist). The one with the collar steps forward and fastens it around your neck, it's not painful, but is degrading...

They take off your clothes and start to measure your cock with the special device. The nurses take some notes and order you to have an erection.

You swallow hard, realizing that they are serious. When the nurses notice your difficulty, one of them, grabs your testicles softly, saying that they are not going to hurt you, you need to relax.

After a few moments, they take the measures and say that it's all done, you are categorized as "virgin". You are not a virgin, but you don't dare to ask or say something... the special device has many sharp edges and you are frightened.

They offer you a new pill, or they will send you to the experimental section of the lab, where the nurses are replaced by automatic systems.
They explain that only no one will risk treating a patient who can be aggressive or lose control and they don't trust you.

You have to choose...
