Day 4: Squirting/overstimulation
F💙 x P💜

I ended up changing some of the promps, starting with this one, cause I wasn't sure what to draw for some of them :p

Also bear with me here, this is the first time I've drawn genitalia and F💙 so they may look a lil weird 😅

#tcest ff Getting an early start on the #TcestOber2026 prompts, and that's what I'm working on for the foreseeable future. :D Starting strong with some pre-relationship Leotello. Hoping it'll be less stressful this year, starting sooner.

Late but thankfully done piece for #TcestOber2026 day 1 and 2

Boner and Humiliation 🤭
Leo was given aphrodisiacs by Mikey then brought to his old crush's workplace, he ordered Leo a kid's meal while he shrinked in shame trying to hide the massive boner he was packing, all of this humiliation because he mocked his little brother for ordering from a kid's menu on their favorite restaurant
