Naked Nuns, religious Erotica.

Religion, namely the Christian one, does not celebrate, but rather surpresses sexuality. It opposes sex, yet, es everryone knows, opposites attract. Thus, it comes as no surprise that the history of Erotica is full of naughty nuns, frolicking with monks and priests, savouring lesbian sex in monasteries or just fucking their crucifix. Forbidden fruit is the sweetest.
