My sister is a pervert
i am 19 yrs old and my sister is 16 yrs old.sometimes,very rarely though my sister walks naked in the house when our parents are not there.3 yrs back also she stripped in front of me and made me fondle her genitals .this stopped after a week though and since then she has been silent about it.i find myself at a dilemma .should i have sex play with her?or suggest a remedy .i think about my sister all the time.
