Therapeutic Threesome: If Your Stepdad Can't Stop Cheating, Join Them

My stepdad has been cheating on my mom. I kept catching him fucking other people, and I couldn't deal with the tension anymore, so we decided to go to therapy. Sure, part of the problem is that I kept walking in on them and joining them, but what was I supposed to do?! He was shoving his big, throbbing cock inside these women, and I was just supposed to go to my room? With my pussy that wet? No way. It's not my fault he has a great dick! Our therapist wanted to reenact the scenario so she could help us, so she sat next to my dad and made out with him as he unbuttoned her shirt and squeezed her massive tits. I was so triggered! She said that it was perfectly normal that I was touching myself, and asked me to share his cock with her. We took turns spitting on it, sucking it, and riding it. When I wanted some pussy, she even let me lick hers! She really was a great therapist. I think we might need another session very soon.
