You guys are dumb, Mara has like troves of beings wanting to smash and Eris is open and you could expect her to like the kinky stuff without having to be her Sub. Plus if you give her good dick, word spreads out, BOOM. Next thing you know, Eris starts hitting up all her girlfriends wanting to try threesomes with you. CONTROL THE ZONES, GUARDIAN.
Judging from all the hentai, Eris has a bigger dïck than you. Just saying.
