#190989 - I didn't want to and I thought I had time so I looked at my Stu stepsisters not fully understanding what it meant and said lets have sex. after being denied and the threat of my mother coming downstairs and I took my bath and forgot about the whole thing until a couple weeks later my younger step sister ask me to follow her to the back room while my parents were gone went inside the room she laid me on the bed and put my hands in her shirt under her breast and let me play with them for so very long time while she put her hands in my pants I couldn't understand why my penis was hard but it was and it made me very tingly at times when she would touch it in ways. Until one day I was home alone that evening and it was just light enough I could see everything perfectly but not straight daylight I stole one of my father's condoms with my heart racing hurried along to feed the calf.
