Over the next few weeks the sexual tension between mum and I became very intense and my dick was never far from my hand, mum seemed less concerned about closing doors to the bathroom when showering or bathing and spending longer draped in a towel after such activities. On two or three occasions I had the opportunity to watch her shower through the opaque screen of the cubicle and she now spent much longer in there than she ever did.
Just to make the picture of mum a little clearer, she is about 5'2", brunette, with a hour glass figure, her breast hang quite high and look wonderful in a bra, which incidentally would be a 34c. Her waist is narrow and stomach quite flat so you would certainly find her in good shape for her age having had four children. Most impressively for me was the thick bush of pubic hair, it covered her pussy mound and continued around to her butt, she kept it in shape rather than trimming it to any fashion.
Mum always dress smart, so for work she'd wear a business suit with stockings or tights and smart heels to match, often her blouse would be see through allowing any on lookers to acknowledge her good taste in underwear, and believe me she had good taste.
I too was becoming more of an exhibitionist and would walk around the house in just my pants and t-shirt, not for my sisters' benefits but to get some sort of reaction from mum. But saying that, with all the horny feeling I was having I was also beginning to look at my sisters in a different way and I would often get semi hard in the presence of any them and didn't do a great deal to hide it, why should I, I'm well taken care of in the underpants department!
With three sisters in the house it was difficult to take advantage of any time alone with mum but sometimes it would just happen, suddenly the house would be empty and the sexual tension would instantly be present. Either of us would find a way to continue with what was happening but still without and dialogue or direction, I still didn't know if this was just me being a horny young man or if mum was just teasing for her own pleasures.
I was beginning to get disillusioned with all the games in as much as we'd seemed to have reached a point where neither of us would take the next step, obviously if either of us had got the wrong idea then it would be highly embarrassing for both of us. I was thinking of ways to move things on to the next level and had fun with many ideas but I had not expected it to turn out the way it did,
One morning I woke early and wandered downstairs, dressed only in my pants I entered the kitchen to find the light on and mum sat at one of our bar stools, she jumped with surprise and stopped whatever it was she was doing, it appeared to me that she was writing in a diary! Now I didn't know she had a diary but suddenly it became the focus of my thoughts, did it contain personal thoughts and secrets? Was it just a planner? Where did she keep it?
"Morning Mum" I said chirpily "what ya doing?"
She looked a little startled as she turned to greet me, as she did she calmly closed the diary and put it on her lap under the breakfast bar out of sight.
She was dressed in a nightie which was short and reasonable see through and it took only one glance down to notice the shape of her breasts and the condition of her nipples, if it wasn't a diary then why was she looking all hot and horny?
"Good morning sweetheart" she countered in a quiet voice "You're up early" not answering my question.
"Year, I guess I couldn't get back to sleep so thought I'd may as well get up."
Still sat there with whatever it was on her lap, the conversation continued about this and that until I got up and went to the fridge to make myself a coffee, I didn't notice the semi hard on in my pants until I stood up and both mum I looked down at the bulge as it was so noticeable. I instantly looked at mum, her eyes took longer to come up to mine but when they did they were joined by a smile.
"My you are turning out to be a big boy aren't you?"
I wasn't sure how to answer her but stuttered out an apology of some sorts about "it always being like that in the morning."
