There was just no way to make myself do it. I coated her belly with my sticky cum.Suzie squeezed me dry that time. We somehow managed to get ourselves...calmed down. I rested my spent cock in my sister's pussy."I had no idea it could ever feel like that," she said to me.I did pull free and my cum came running out from her pussy. There was some blood as well.
