Facesitting lesbians

I have a competition in mind, breath control. So having Mini on the bed I start facesitting her in my lingerie. Somehow she seems to like having my perfect ass on her face, at least until she runs out of air. So I remove my panties, and give her a nude facesitting. Mini do the same to me, and it is harder than it looks. Having first her panties on my face, then her nude ass and pussy. In the end we need to have a winner, so whoever can survive the longest is the champion. I won!
