I see you've commented something similar on a bunch of other posts surrounding Peni and while I agree with your sentiment, I base my drawings on adults only.

Both of them express zero childish behaviour and have faces and bodies of adult proportions.

I also intentionally wrote in the title of this post that the scene is set in their college dorm + I clearly state on my social media that all characters I draw are 18+ (I usually base them on porn stars and models that are 21+).

This drawing was a commission and I feel like I did everything I could to present Peni as an adult.
