KImber lee tief in den hals üben mit meinem stiefbruer

My boyfriend finally told me what he wants as his Christmas gift. He wants a blowjob for his gift but I don't know how to give a blowjob! I want to make sure it's a really good BJ but I need help from someone I trust first. Ya know, we're not fully committed, right? I could practice on you and you can tell me if I'm doing good or not!
