I was watching my sister in laws house while she was on vacation.She is a 48 yeaar old full figured lady with big tits and a large round ass.While passing by her bedroom I noticed her dirty clothes hamper. Looking inside I saw a light blue pair of cotton panties.I pulled them out and headed for the bathroom. I stripped off my clothes and sat on the toilet and raised her panties to my face. I inhaled deeply and detected her very wonderful feminine aromas. I then began to lick and suck on the panty crotch until it was totally clean.I then eruped with a large creamy load. I cleaned myself off with her panties and placed them back in the hamper.
