No Jerking takes place Hands free knob job. She's working the head with her tongue and males him come. Bro/Sis? Who knows, but it's obvious she has done this before cause she knows exactly what he likes
I have to agree that she uses awesome tongue action to make him cum. At the end I don't think that's cum draining out of her mouth looks more like extra spit to me. I do love the eye contact.
