Osa's workout plan really should not have included cheap protein shakes on top of a long jog. Now she's sweating up a storm and about to fart herself right out of the room! All she wanted to do was relax on the couch after a hard workout, but now Osa is straining at her barely-there shorts to pass hard gas! Everyone loves an ebony girl with toned, tight muscles, but after this workout Osa's sphincter will be the tightest muscle of all!
