Step-Dad Wants to Join This Time!

Story - After sneakily filming my stepson & stepdaughter fucking eachother, I decide it's time to lay it out on the table for them. I confront Tyler Steel & Paisley Pepper, he immediately turns on her, blaming Paisley for ratting them out - not knowing I had secretly taped them. They expect the worst and are shocked when I tell my stepson to fuck my stepdaughter, showing me what she likes. They seem anxious to do it, but nervous that their stepmother will find out - I reassure them that nobody will find out. Tyler pounds her even harder than before until I kick him out before he can finish. Alone with my stepdaughter, I start jerking off in front of her while she rubs her clit for me until I shoot my thick white all over her.
