Jerking off my Step-Brother And Step Uncle. Riley Reid

My ex-wife's step-brother's spawn are spending some time at my house since he and his wife are on a summer long European vacation. I don't really know what to do with them but since they are both over 18 they seem to be self sufficient. My step-nephew is definitely the lazy one of the two and my step-niece is quite the little ray of supple skin sunshine. She made me my favorite breakfast and coffee to give me a great start to a work day. I try not to stare too much at her but sometimes I cant help it. I cant help but wonder if she purposely was holding her knees and flashing me her pretty lace panties as she talked to me at breakfast though. I think she may not be as innocent as she looks.
