Doodling armpit (Patreon)

Still on artblock, but I'm trying to draw something at least. So today I did a doodle. 

I'm wondering why armpit fetish is blooming recently. Many artists drew armpits looking like p*ssy, it's plump, it's moist, it's pinkish white, making me think that the world of ecchi is truely vast. By the way, I also love armpit.  (LOL)
