Disabled or improved? (Patreon)

some weeks ago i made a couple of  illustration out of my comfort zone, (the amputee and the pregnant girl, the second one not out of my comfort zone for the theme, but more for the purpose and the person who asked me), i've also told you that i would have drawn a third "uncomfortable" piece about disability.
Today i can show you and i hope you like it.
I don't know if there is someone with any sort of disability here, but in this case i'd like to have a feedback from you.
I know i only touched lightly the argument, using a joke to introduce it to the audience. Sex and disability is anyway an important theme, because disabled people has their right to have sex and explore their sensuality, even other people can see them as frail or ill subject who can't experience sexual life like everyone else. But they are horny and have kinks like us, as you can see in the drawing :)
