My brother walk in on me

so I was in my parents bed laying there with my mommy's vibrator going between my thighs because I was super horny and love getting off with her toys and my brother walked out and looked into her room then walked off and I covered myself then came back only seconds later to pay the dog on the other side of the bed and I came right as he was watching and barely was able to stay quiet as he left and went straight to the toilet
