I come into my big boy's room and am extremely horny. Since my big boy is the only one in the house, I have no other options to relieve myself. My biggest fetish is to say the word "penis" over and over. I need to use my big boy's "penis" to help me relax. I pull back the bedsheet and pull down his underwear. I proceed to touch his penis and expose my breasts and ass as well. I start to masturbate as I continue to stroke him. After I orgasm I make sure that he cums so he feels as good as I do. After he cums I tuck him back in before leaving.
