A lot of free time at my hands in my summer break gave me a golden chance to help mom around the house. Having an attractive working mom, I could not help helping her in very exciting ways. We went out on a couple of seductive dates, then we became lovers.
Mom's prim behavior and somewhat aloofness annoyed me. I grabbed a golden chance when she could not get back at me and misbehaved. When she talked to me about it later, I completely misbehaved and she liked it a lot. Finally I managed to get rid of her rough edges.
Working out so often made a friend of mom's consult me on her physical fitness. Then it turned out that for her to shape up, I needed to work out with her as well. What a workout!
