It jumped to attention as though it thought it was gonna get some relief but none came and it wilted down again."now get down on your hands and knees ...nd carry me to the bedroom"not wanting to get whipped i did so fast as i could"good now undress me and and draw a warm bath"The warm bath could wait as i undressed my sister with clumsy fingersFirst her shoes moving up and saving the best area for last i took her shirt then shorts off and getting another hard-on i slowly peeled off the magical.
