Looking down at Diddo as she expertly massaged my body. Then with her puppy dog eyes stairing back at me she asked if I would go shopping with her. I just couldn't resist her and pulled her up close to me and gave her a long kiss on the lips letting her know we would go shopping. Diddo slid down my body and slowly pulled my shorts off and set them neatly on the floor. Revealing my already hard cock through my black thong panties I was wearing. Feeling really turned on take off my shirt and bra as Diddo is kissing and teasing my cock through the panties. "Diddo you are the best sister a girl can have. Not sure I can take much more." That is when slid the panties over and start to lick from the base of my balls to the tip of my cock. To keep from cumming so soon as she is making it feel too good I ask Diddo what kind of shopping she would like to do.
