I should have realized that it was all part of a game.
Monday morning, I was awoken by Susan gently stroking my cock. I had been having a wonderful erotic dream (or was that brought on by Susan's ministrations?) and was fully hard. She gently stroked my cock, and I could already feel a small dribble of pre-cum leaking from my cock. I rolled onto my back so that Susan would have easier access to my cock and hopefully so that she would climb on top of me and lower herself onto my erection as I knew she liked to do.
Just as I was on the verge of climaxing, I heard Susan's alarm go off. She let go of my erection to silence the alarm and then climbed out of bed. I looked at her incredulously.
"You know that I am helping Carol out in her lingerie shop this week. Sorry but I can't be late. Save yourself for later."
At that my erection started to subside but a promise is a promise, so I expected to be able to relieve my horniness when Susan returned that evening.
We were actually retired but Susan had agreed to help her long-time friend Carol out at her lingerie store as her normal assistant was on holiday and there was a big release of a new range of sexy lingerie this week.
Lunch time the phone rang. It was Susan.
"We are so busy I have hardly had chance to stop. This new lingerie doesn't leave much to the imagination, but it seems very popular, maybe I should buy some before we are sold out. I am getting so turned seeing all of these scantily clad women and being so close to their nearly naked bodies, if I had time, I might even have had to have a quick stroke of my wet pussy. I bet you can't wait for me to get home"
She really knew how to get me going especially after leaving me hanging first thing. My cock twitched.
"Please save yourself for me and then we will both be horny for this evening." I replied
"I'll try."
To pass the afternoon I did a few errands and then went off to the gym to try and distract myself from the erotic thoughts I was having. When I got home again it was time to prepare some supper ready for Susan coming home.
When Susan walked in the door we kissed and a ran my hands over her lovely arse.
"I'm exhausted. I had no idea how hard Carol worked in that shop of hers."
"Well supper is ready, glass of wine?"
"Yes please."
I poured Susan a glass of wine and then went back to the kitchen to serve up supper. It was nothing too fancy but we both enjoyed it with another glass of wine. As Susan finished, she rolled her shoulders to release the tension of the day. I got up and walked round behind her, slipped the shoulder straps of her dress down and started to massage her shoulders. Susan sighed and visibly relaxed, but when my hands started to roam down towards her breasts she tensed again.
"I'm sorry, I have had a long hard day...Can we save this for another day? I am going to go and have a nice hot shower and then lay in bed for a while and read my book before we settle down."
I collapsed in front of the tele and watched my favourite series for a while, when I heard Susan head into the bedroom, I decided that I might as well have an early night and read my book as well.
We both snuggled up in bed and eventually switched the lights of and settled down. We usually slept with Susan laying spooned behind me so when I felt an arm slide across my body, I didn't think too much about it. Susan's hand came to rest by my cock and it inevitably stirred with excitement.
"Perhaps she has had a change of heart" I thought to myself.
Susan wrapped her hand around my cock and squeezed gently, in a few moments I was fully hard. I tried to move my hips so that I could rub myself in her hand, but she had too firm a grip. I lay there for a little while and Susan alternated between gentle rubbing and squeezing. I was getting more and more aroused but there was little I could do except submit to Susan's ministrations.
After a couple of minutes Susan loosened her grip and stopped rubbing my cock. She just kept her hand resting there. Although this was pleasant enough it was all the more frustrating and I started to lose my erection. As my cock softened, I felt Susan's hand once again take a firmer grip and start to rub me.
"What is she playing at" I thought but nothing I did allowed me any more stimulation. As soon as I was fully hard, she relaxed her grip again and I started to soften. Susan repeated this cycle 4 or 5 times. Then as she gripped my cock again, I perceived that her breathing had changed, and she had fallen asleep. So, there I was my cock covered by her hand, unable to touch myself or increase my pleasure. I just had to lay there getting increasingly frustrated.
Eventually Susan rolled over and released me and I was able to get some sleep. A night of erotic dreams and random erections followed but I didn't want to just bring myself off to relieve myself.
I was awoken the following morning by Susan again taking my cock in her mouth. Only the head of my cock, but it was a very nice way to wake up. She licked round the opening at the tip of my penis, and I moaned with pleasure, hoping that this time my arousal would be brought to a proper conclusion.
Just as I was nearly at the point of no return Susan's alarm went off. I don't know how she timed it so badly for me, but she let go of my throbbing penis and reached over and silenced the alarm.
"I am so sorry I thought I would have time to finish you off this morning. Please don't waste your seed but save yourself for me."
With that she headed off to the bathroom to get prepared to go off to work.
I couldn't decide if she was doing this deliberately or if it was just a coincidence. I rolled over and tried to go back to sleep but my cock refused to soften properly and wherever I lay I could feel it throbbing desperate for release.
I spent the day working in the garden and was ready for a rest by late afternoon. I had just sat down with a beer when my phone pinged. It was a photo from Susan. She and Carol were modelling the new lingerie that she had been selling. She wasn't kidding when she said it didn't leave much to the imagination. The bra was no more than a quarter cup and left her pierced nipples uncovered (and hence accessible). The panties where barely a triangle of fabric covering her slit, but it was also so sheer that I could see the outline of her labia and her hood piercing. Carol, who also had similar piercings was as exposed. My already frustrated cock sprung into life. I texted Susan back and told her that she had better buy the lingerie and then model it in person for me.
Susan messaged me back "Not this evening I am afraid. Carol has offered to take me out for a meal to thank me for all the hard work. Don't wait up".
