Got Step Dad To Become My Perverted Sugar Daddy Behind Mom's Back

It wasn't hard to get my step dad to buy and give me things. He's the one that offer me to be the g*ft giver. I had the habit of being topless in a loose tee shirt around the house. I didn't like my long sagging tits in a bra. I started to notice him down blousing me and peeking in my room. Then one day when mom was out he approached me. He offered to be my sugar daddy if I paraded in front of him with my tits exposed shaking them about and watch him jerk off. The idea of watching him kind of turned me off to his offer but to get things and have him pay for them made me say I'll do it.
I removed the tee shirt I had on. He was was amazed that I had such big areolas on my tits. I began to parade about swinging my breasts smiling at him. He undid his pants and started to wack off. " I'll give you twenty right now if you slap my penis." I stopped and thought it over. It wasn't that he wanted to hump me but to slap his dick. I decided to do it if he handed me the twenty. He handed me the twenty and I let tits my hang while I slapped his cock. " Keep slapping it, slap it harder ! " He finally ejaculated. Mom married a weirdo I thought to myself. I wondered if mom slaps his dick.
Anyway, as long as I bare my breasts to him and slap that dick I get plenty of goodies.
