I highly recommend 'Karryn's Prison', if you haven't played it yet. The sort of debauchery the female MC can indulge herself in while technically remaining a virgin is on another level. If only DAP penetrations and ass-fisting were introduced, it would be a perfect game for those of us degenerates that fantasize about total slut virgins.And if you want to sugest some of those games im open to it, there may be a game or 2 that im missing.
There is also 'Degrees of Lewdity' where you can help your PC protect her virginity with chastity belts and she'll still be able to be the most popular whore in the Brothel and more.
