It was fun settling in to the new, still loving, but now very sexual relationship with my step mother. As weeks past we explored on another more and more. My step mother, Terri, leaned of my love of her panties and pantyhose, and how it got me off to see her pussy through her tight pants and shorts. I had learned that Terri likes sex to be a little rough sometimes, and that she likes to be spanked and pinched. And I came to realize how much I loved doing these things to her.
I was very young, somewhat immature, and very inexperienced when Terri and I began our new relationship. I wanted to make sure that I was pleasing her so I started doing some research. I watched a lot of videos, read sex manuals, studied the Kama Sutra, and found friends I could talk to about my situation and my step mother's needs.
While reading I came across some material that covered submissiveness. This was not something I was familiar with, but as I read I began to think that Terri was either openly, or inwardly submissive. I decided that this was worth exploring further.
Terri had spent much of the afternoon in the sun, but I was studying for a summer college program so although I was as tempted as always, I left her to her tanning and just peeked at her through the window. In the late afternoon as she came back inside she hadn't bothered to put her bikini top on. She strutted her little bubble but, wrapped in a tight and tiny bikini bottom, right through the family room and in to the kitchen. She knew that she had my attention, and that I was staring at her ass as she opened the fridge and bent over to grab a water bottle from the bottom shelf. Before she reached for the water she slid her index fingers into the leg openings of her bikini and pulled the sweaty material out of the crack of her ass. My cock began to grow immediately.
Terri took her water, looked over her shoulder and winked, and told me she was going to take a nice long shower. She may as well have taken a lipstick and written Fuck Me all over herself. My step mother is such a tease, but unlike my 18 year old girl friends, Terri never failed to put out.
I let Terri have a few minutes to get good and comfy in the shower before I walked in on her. At first I just watched. My step mother is so gorgeous; I was in awe for a few minutes as she touched herself. She massaged her breasts long past simply washing, and then she leaned her back against the wall of the shower and let both hands wander to her pussy. I was quietly enjoying the show as my step mother masturbated. With one hand she rubbed her clit, and with the other she began fingering herself. Terri didn't open her eyes, but I know that she knew I was watching. She was masturbating as much for me as for herself.
Terri was now using both hands on her cunt, opening herself wide with her fingers. My eyes were glued to her as I had not seen her do this before. She was giving me a naughty anatomy lesson, and I was a good student. I could see her swollen and erect clitoris, her pee hole, and her puffy labia, all displayed for my pleasure. When Terri turned around and reached back with both hands to pry her ass cheeks open I almost came in my shorts. Her back was arched inward and her ass jutted out, and she had a very firm grip on her lily white cheeks. The pure white of her ass, and her ass crack were an amazing contrast to the rest of her tanned body. The way she had her ass pushed back I could see her long pussy lips hanging down, and the puckered slit of her asshole looked like it was aching for my tongue.
I had taken all the teasing I could stand. I quickly stripped naked and looked down at my cock. It was so hard that the swollen head looked angry and the skin on the head of my cock was so taut that it shined. As I opened the shower door my step mother played as if surprised and embarrassed. She made an attempt to cover herself, although there was no part of her body I had not laid my eyes, and tongue, on. I gently pushed her up against the shower wall, and standing behind her I began fondling her body. My erection was pressing against her ass and sliding across her hips. We were not speaking as my hands massaged her back and shoulders. I made the decision that this was a perfect time to see just how submissive my step mother might be.
With Terri still pressed against the shower wall, I wrapped one arm around her, my hand finding her tits, and with my finger I began pinching a nipple. My other hand slid up her back, between her shoulders and up her neck. I now had a full handful of my step mother's hair and as I pulled her head back I spoke into her ear, "get on your knees."
Terri was caught off guard and tried to look back at my face as she said, "What?"
I released my grip of her boob and slapped my hand hard onto her wet bare ass cheek. The sound was surprisingly loud due to the confinement of the shower, and the wetness of her skin. I had spanked her much harder than I had planned, but it felt so good.
"Owwww" Terri said, but she didn't kneel, so I slapped her ass again.
Pulling her head back by her hair again, "I told you to get on your knees," I whispered directly into her ear. This time I didn't give her any time to respond before slapping her ass again.
"Baby," she whimpered, still standing. This earned her several more slaps to her perfect ass.
