You decide that you don't want to expose your ass or your penis to any damage, so, you prefer the degradation of cum drinking.

You are blindfolded and tied to a stretcher. The nurses force you to use an open-mouth gag, you can't close your mouth and they connect a painful sound to your cock. Once the sound is secured, they slowly start to masturbate you, until you are ready to cum.

You don't know but the sound is connected to a small hose that will pump your cumshot directly into your mouth when it is still warm.
You experience an orgasm, and immediately after that, you feel a weird taste in your mouth. It's sticky and difficult to swallow, but the nurses instruct you to swallow it.

Multiple times a day, they stroke your cock and make you drink your cum, but after almost a week, this is not torture anymore, you get used to the taste of semen, and they decide that you are ready for the true punishment.

Task: On a table, put on an open mouth gag, a blindfold, and masturbate using rubber gloves, using a vibrator on the tip of your cock. When you cum collect the semen in a glass, load a syringe, and spurt it inside your mouth when it's still warm. Swallow.
