Joins in on the activities

" What are you doing" Makenzie gasped as her blond, fit, and b sized breast cousin lifted her tank top over her head exposing her boobs that, unlike Makenzies, was not in the embrace of a bra. " You see kenz.." Bonny continued as as sat down and slowly pulled off her leggings exposing her private area that had no panties to protect it. " I have decided to be more open, and nothing sounds like being open than stripping naked and spending the day with my favorite cousin" as said with nothing but a smile on her face. " Ok I can get that I guess, but why have me strip to" Makenzie said shocked and still covering her self. " Because I was nervous" Bonny said as she walked around the table and pulled two shoe boxes out from behind one of the legs. " and besides, you have a great body, why not show it off." Before Makenzie could reply, bonny opened a box and threw a pair of blue sneakers at Makenzie causing her to let go of her lovely tits and catching the newly out of the box shoes. " What are these for?" Makenzie asked. " For running of course" Bonny said as she slipped on a pair of pink shoes similar to hers. " You lost the bet Makenzie and the bet doesn't end until you streak with me". " What the hell No!" Makenzie said as she moved towards her cloths. But before she could protest, bonny slipped on her pink shoes and sprinted out the front door. What will makenzie do?
