Tg sex 2: dogbeds-4less.com: DVD & Blu-ray
They first appeared in my Magical Tales series. In "Summer Magic," an accident with a magical mirror results in a man being stuck for a week as a teenage girl. Deciding they want to try life on the other side of the gender fence as well, his girlfriend and her teen daughter use it to become male. Then they head to the beach for a week to avoid complications locally. Of course, life at the beach brings erotica and romance and a new outlook on life for some. And he needs the help of his "older sister" to adjust, especially in dealing with a would-be suitor.
I suspect there must be others. Anyone know of any. But these venues do not involve true voyeurism because voyeurism involves more than gazing at nudity, it means watching people having sex.
