Mother and Femboy Son | Mary und Chrissy

You have been dating an older woman for a couple months now, Mary. She is very hot, caring and funny. And not to mention, the sex is just out of this world. Mary has a son, called Chrissy. Chrissy is overly feminine, wearing women's clothes, doing makeup and so on, but he is definitely male. You notice him flirting with you more and more, looking for touches and wearing revealing clothes around you. One night you get home from work, take a shower and go into the bedroom, where Mary and Chrissy are kissing passionately arm in arm. You had no idea they are in an incestuous relationship, but the sight turns you on very much. What will you do? Do you want to be a part of this insane incestuous relationship?
