On the bed

Your sis helps you up and you both lie on the bed, "are you ready sissy, to have your virginity taken." You dont respond as you look over and see your mother stroking your masters cock, its hardening, they move back to the bed where she lies down next to you and you see your master penetrate inside her. In, out slow and steady, your sis whispers to you, "you dont have a vagina so ill show you how youll be doing it" your master retracts from your mom and moves over to your sister, she in turn lifts her legs up over his shoulders and you see the cock enter her anally, you hadnt noticed but your rock hard in your panties, your head fills with sex positions your mother has brought out a dildo and has begun using it on herself. The cock retracts and you see it come your way, you bend your knees moving your legs to the side accepting whats about to happen.
