This is Chime (F) and Chilli (M) from one of my webcomic ideas: SCRW-U Squad. Chime was created sexless but luckily, she's able to telepathically sync with her bf Chilli and feel orgasms through him. Which works out well because there's no way she'd get that D in her.
Unlike a lot of my other stories, SCRW-U Squad is plot with some porn and is about the hijinks of a space mercenary crew who all share one brain cell. (Think Guardians of the Galaxy but queer!) Chime and Chilli are just two of this crew, there's also a four-armed, big-boobed, butch wlw, her mlm best friend, his split personality, and their totally-not-a-Rocket-Raccoon-ripoff furry captain.
