When he came into the kitchen for some breakfast he saw a sight that blew his mind. His sister was sitting naked on a chair having a cigarette. He was speechless. But she wasn't and she invited him to come closer and touch her naked body. He did and they kissed and then he kneeled down and licked his sister's delicious pussy! She had fun and came quickly and to thank him for that she took his thick cock into her mouth and gave it proper sucking! A blowjob from your own sister is the best thing ever!
