Sabrina loves hitting the gym but needs to work on some cardio. Great way to do that is aerobic steps, Sabrina doesn't have a step so she orders rugboy to lay down and act as a step. Sabrina gets very into her workout as she steps up and down onto his chest, stomach and groin as her workout routine. Sabrina is not fat but athletic and rugboy can feel her muscle weight onto him. Sabrina loves doing this routine for 6 mintues so rugboy has to endure. (this is full video)
