It had been a whole year since my parents divorced. They split because of constant arguing, or rather my mum moaning at my dad until he finally flipped and kicked her out. Mum was usually the impulsive one, making decisions without thinking of the consequences. Dad was always calm and rational, sometimes so placid it seemed like he didn't care.
Nobody else was involved, but just three months later my dad announced that his new girlfriend was moving in with us. I liked Sally as soon as she moved in. She had a silly sense of humour like me, and we often found ourselves giggling at silly things while watching TV, sometimes to dad's annoyance if he was working on his laptop or reading a book.
Being twenty years old I'd stayed at my dad's due to it being much easier for me to get to university, not what my mum thought that I was taking sides. Sally was younger than my dad's forty-three years of age, being just thirty-five years old herself. Despite the age gap they seemed very well matched and had reasonable discussions about things. Sally settled in well over the last nine months and dad was very happy again.
Sally was very pretty, dad had done well for himself there. Her dark brown bobbed hair, normally tied up, had an eyebrow level fringe and she always left bits that hung in front of her ears, framing her face like a picture. Despite being pretty I couldn't tell you what her body was like, she always wore loose-fitting clothing. Even her pyjamas or nightwear were loose-fitting too.
It was hard to think of her being sexy because of her age and how we laughed like schoolkids, she was more like a big sister to me. The only remotely sexy thing I'd noticed was pegging out washing on the line outside one day and saw that all of her lingerie was lacy. I'd started to try to picture her wearing them, but not knowing what her body was like found it hard to visualise. I quickly shook the blurred images from my mind.
I'd heard them having sex before and just put headphones in to drown them out with music. That same night of seeing her undies on the line was different. I heard the unmistakable sounds of Sally moaning and groaning, and instead of drowning it out, I lay listening to her. I found myself imagining her riding me, that pretty face scrunched up in pleasure, her hair wet and matted across her forehead where she was sweating. Without realising it, I had stroked my cock to erection. What the fuck are you doing, that's your step mum? my mind shouted at me. I quickly put in my headphones to take my thoughts elsewhere.
Sally sensed me being more awkward around not just her, but both of them, over the next few days.
"What's the problem Danny?" she asked when my dad had gone to work, "I hope you know you can talk to me about anything?"
"Well, it's a little embarrassing to say, but I heard you guys having sex the other night. Normally I'd just put in my earpods but I'd left them downstairs," I answered, mixing a little white lie in with the truth.
"Oh I'm really sorry, we'll try to be quieter from now on or at least wait until you're out," she told me.
"It's my issue, you guys don't have to change because I'm still here. I don't expect you to stop having sex because of me," I said, trying to come across as mature.
"Well that's very good of you, and I'm sorry you had to listen to us, it must be especially hard with you not having a girlfriend right now," she said.
It had been especially hard, she was right there, but I don't think she was talking about my cock. I wasn't sorry I had heard them, but I couldn't tell her that. I also couldn't tell her that I'd been masturbating listening to her, or that the sounds of her moaning were stuck in my head. I'd tried to get rid of them since she was my step mum after all.
A few weeks later I got my first glimpse of her body, or at least a better understanding of what it was like. I'd been at uni and instead of going out as I'd planned, I returned home instead. I used my key to unlock the front door and went in, shouting out as I did so. Getting no answer I assumed dad had gone to the office and Sally was also out. I went straight upstairs and began stripping off my clothes to go and shower when I noticed something from my bedroom window.
My bedroom is at the rear of the house so looks down over the pool and into our garden. Sally was in the garden in a pair of black lycra shorts and a white t-shirt, jogging around the garden and stopping at certain points where there were dumbells and small weights, which she would use and then continue around her laps. It was obvious she'd been out there for a while, her hair was matted and wet, her t-shirt although loose was wet through with sweat and stuck to her breasts.
I watched as she jogged around, the t-shirt bouncing around as her breasts jiggled underneath. They were bigger than I'd given her credit for, certainly bigger than my mum's and big enough that I wondered how loose her tops really were they I hadn't noticed them before. I realised I was standing there naked watching her through my window, my semi-erect penis telling me I was enjoying the sight a little too much.
I wandered out onto the landing and went into the bathroom, shutting the door behind me. While in there I had a thought. Digging around in the washing basket I found one of her bras. 36C. Nice size. Again I wondered how I'd not noticed them before now.
I got into the shower and started to clean myself off, but couldn't get the images of her bouncing breasts out of my head, By the time I'd told myself that this was so wrong it was too late, as I came over the shower curtain. I hadn't shot a load this heavy for quite a while.
I got out of the shower and towelled myself dry, noticing in my haste I hadn't bought any clothes with me. I wrapped the towel around my waist and left the bathroom, just in time to bump into Sally on the landing. She had a small hand towel on her, wiping beads of sweat from her brow. Her soaking wet t-shirt clung to her, her hard nipples visible through the stained material.
"Oh god Danny, you frightened me, I didn't think anyone was in," she gasped.
"Neither did I, I did shout out when I got home," I answered.
My eyes wandered down her body and back up quickly, just in time to see her bite her lip as she looked at the bulge in the front of my towel. It's not that long, to be honest, five inches when soft and seven inches erect, but it is very very fat. She quickly averted her gaze, hoping I hadn't noticed. Not only had I noticed, but I could also tell that she'd enjoyed the view.
She brushed past me, telling me she needed to shower herself. As she entered the bathroom, I had to stop myself asking if she needed a hand. I went into my room to dress, leaving the door ajar on purpose. She also hadn't got any spare clothes with her, so would have to walk past either naked or just with a towel wrapped around her.
I lay on my bed with my head at an angle to get the best view, putting my earpods in to make it look like I was listening to music, but didn't switch them on. It was a quick fleeting view when she did walk past, the towel wrapped around her but barely covering both her breasts and her arse. I thought she'd momentarily paused at my door, but put it down to me hoping she had. I masturbated again shortly after. I knew it was wrong to be lusting after my step mum, but I just couldn't help myself.
Nothing really changed after the incident. We still had regular giggling sessions in front of the TV, but I'd found myself getting into situations where I could touch against her. Not excessive, just things like if she was in the kitchen I'd go in to make a drink, our hips grazing against each other as I reached for my mug, or brushing my fingers across her arm as I reached for something, just enough to seem accidental.
A few weeks afterwards we were watching TV with dad getting agitated while we giggled with each other. He got up and said he was going to bed, he had an early start the next day to go to a big meeting a few hours drive away. Sally asked if we were upsetting him, and he replied he just wanted a good nights sleep as it would be a long day. He kissed her on the cheek, smiled and fist-bumped me, and went upstairs.
