My sister wakes up in the presence of the cock

My sister is so used to having a penis in the mouth that does not matter if he sleeps, does the work with the language. And if you do not believe me, here is the video where you can see for yourself. He was sleeping quietly, so I went in his room without making a sound so not to wake up. I pulled out his cock from his pants and I put it to his lips. She opened her mouth as a reflex, and while he was still asleep, she began to suck my cock. Tell me, is a whore or not? Because for me, this is proof enough. I sucked the penis for a while until the excitement has not woken up. It was then that we fucked. I have to admit that it was very amusing to see his surprised face when she woke up.
