We definitely have plans for pegging. Right now, we're trying to solve how players can appreciate the experience by thinking through mechanics. If the Mistress is behind during doggy style, we'd like the player to have a mirror so they can see what's happening (but this would require us to get player avatars into place). Another option is to have the Mistress in front, missionary style, which would still need some form of avatar, but not require the extra feature of a mirror. Believe us, we're thinking about it! Always so many ideas and never enough time :)
