I find my stepdad erect, so I masturbate him while showing him my huge tits. For some reason, I couldn't rest despite the fact that it had been a tiring day. After tossing and turning, I decide to go to the kitchen to get a glass of water. On the way, I hear someone calling me from the guest room, and to my surprise, my stepdad is there, fully erect and with a long, black cock.
