Looks like Senat made the team, but maybe not in the way he expected.

Senat might not be the most athletically-inclined boy out there, but I'm sure Coach can find a place for him on the team.

I don't play ZZZ, but Von Lycaon could spit on me and then turn me inside out like a gym sock and I'd thank him for the experience.

I am currently hyperfixated on my gay little jackal twink, so I’m sorry if you don’t like drawings of boys with waists that just beg to be gripped until you leave marks. It will happen again. Apologies. 🥺

Looks like Zara got on the boss's bad side somehow. And just because she's heavily augmented with biotek doesn't mean she's gonna be able to bust through some good ol' heavy metal bondage. Follow-up pics available to patrons

I ended up doing about 20! I know more characters were submitted than that but I did at least attempt as many as possible haha

Anyway it was a very fun stream and I look forward to the community getting to doodle party 5!

Extra page!

It always seems like something is missing. And this time it was fixed.
Сold metal touched and pierced most sensitive parts of the body to become as reminder...

...a reminder of obedience!

Malakai seems to have ended up on the wrong side of some sci-fi villain and gotten himself 'contained'. At least they were kind enough to give him some 'stimulation'.
