Cumming With My Little Sister I've watched my little sister play with herself a few times before.. I couldn't stop myself from getting hard even though I know I shouldn't like it. She's just so small and perfect... Yesterday I saw her using a toy and asked her to let me help her. She was scared we would get in trouble, but I told her we would be fine.. I slid the toy into my little sister and kissed her, I could tell she wanted more....
