You wake up

Bzzzzzzz!

The next day you wake up for the vibrations going through your body. Your muscles still sore, you tense your arms against the straitjacket's material, and renew your motions against the straps. But you can’t do anything.

"MMMMMM!!!" The vibrator stops again, and you scream into the gag from the frustration.

You throw your head against the pole. But it hurts. A lot more than you thought it would. You also recognize that you should be in more pain by now due to the position you are locked into. You know this from experience. This means that the nanites were injected in your body while you were out, however your sex drive remained unaltered.

Bzzzzzzz!

The vibrations go through your body once more. You tense your arms against the straitjacket, and renew your struggle against the straps. But your muscles are sore, and you resort to stay idle, enduring the ripples as they go through you.

"MMM!!!" The vibrations stop again, but this time you make a lot less noise.

Bzzzzzzz!

The vibrations go through your body again. But you just stand there. You can’t do anything. By now you accepted that. All that remains is to preserve your strength.

The vibrations stop again, and you don’t even make a sound.

Bzzzzzzz!

The vibrations to go through your body once more. Again. No reaction.

Bzzzzzzz!

The vibrations restart. But again. No reaction.

Bzzzzzzz!

And you continue to employ this tactic until the day ends.
