It will probably be seen as something weird for a while but just, if you can and with calm, tell your sister you never did and will never do something to her in those lines (if its the case)
Also just say its something you like, be it the artstyle or the usual environment of a more carefree/light sexual relation
I can surely relate to less "hurr durr me fuck girl" and more tenderness in porn
