Meine stiefsis schiebt versehentlich meinen schwanz in sie, während sie VR - Delilah Dagger beobachtet hat

I went to my room and saw that my door was open. I peeked inside and saw my step sis on my bed watching VR. Eventually, she started masturbating so she had to be watching porn. I couldn't believe what I was seeing but it was so hot. I slowly crept up, jerking my dick, waving to see if she could see. Nothing. Suddenly, she drops her dildo and grabs my cock and slides it inside of her. Eventually she realizes and I apologize but she said it was better since it's the real thing.
