Tracer (Tier 1: Lineart) reward (Patreon)

Some notes:

   1) As per decision of the last vote (10$ tier patrons), Tracer will live with 3 different modes/variations on her gas-mask : Aphrodisiac (can't cum), Aphrodisiac (can't stop cumming), and finally asphyxiation (non lethal). Some of the facial expressions here reflect this.

   2) Added two X-rays views: 

- One is a breathing valve opening inside her mask which gradually shrinks more and more as she  inhales. (This only happens when asphyxia mode is active and gradually shrinks until no air can go through and she passes out of asphyxiation. It opens back to let her breath again after that.)

 - The other: a massive capsules (Size of a pineapples) being injected anally through the buttcord. These capsules are filled with vitamins, proteins, fat, and other things. The capsule slowly (hours) travels up her intestines, until it reaches her stomach. At which point, it dissolves. Releasing all the nutrients. This is how Tracer will be fed from now on. Uncomfortable for her, but effective.
