VC - Wait what

"What's variant C?" you ask worriedly.

Moira does not answer you... she goes to a refrigerator looking thing and unlocks it, taking out some kind of injector. The voice is gone. It's just you and Moira now.

"Do you want to leave?" she asks.

"Yes!"

"Then cooperate," she tells you.

"OK. Fine." You stare worriedly at the injector. She releases the restraints on the table, and you sit up.

"Stand," she says, so you get up, shivering. You try to cover your penis, she has already seen it plenty...

"Turn around. Put your hands on the wall," Moira orders.

Getting more worried, you embarrassedly turn around and do as she says, presenting your naked back to her.

"It won't hurt you," she assures you, and you hear her coming closer... "There will be one immediate side effect."

"What side-Ah!" you scream as you feel a sharp pain in your buttock where she stabs you with the needle. The pain is followed by intense pleasure as your half-hard cock erupts all over the wall and you feel a gush of juices from between your legs. Numb and in ecstasy at the same time, you fall to your knees, splashing into the mixture of juices and semen that you spilled to the floor. You fall and smack onto your back, your hips jumping and more cum spattering your chest and face as your aching cock refuses to quit.

The last thing you remember is Moira standing over you with the injector.
