In a recent post on my DeviantArt page, I've revealed that the Interdimensional Dominatrix, Princess Sophie, is actually a virgin! To her credit, it's not worth her time finding suitors to lay with when she can make herself "c*m a million times just by thinking about it." But to Yui, a normal Earth girl, it's pretty embarrassing that Sophie has never had sex.
In a comic that I intend to get to at some point in the future, Yui will take her extraterrestrial girl-friend clubbing and teach her how Earth girls pick up boys. But considering both of these girls' out-of-this-world beauty, it's likely that they'll find plenty of guys that want to bang them, but not enough guys that they want to bang...
