I think this one was an /aco/ request, this was one of my first posts on my tumblr (rip)
Ps. So get this: there's an nsfw animation out there of D.va and Mercy in almost these exact same poses. The artist who made that, I bet, used this pic as reference. If that's true, that would be so awesome knowing it inspired that. Not that I invented two girls kissing, but believe me they were very similar.
