So my caught in the act took place whilst in the discovery faze in life shall we say! I was starting to enjoy wearing panties and would at every chance raid my sister's draws and try on pretty much everything before the excitement took over and I'd masturbate away all that excitement.

One afternoon with the house to myself I was trying on the favorite panties and got excited so started masturbating while still wearing the panties. Before long I could feel the orgasm build and just as that first gush shot out into my tummy, the door pushed open to show a very shocked look on my sister's face! Caught masturbating, on her bed, wearing her panties and mid orgasm! Couldn't get any worse!!!
