"Jan my dear would you be kind enough to pick up my prescription for me? I have nearly run out."
Jan reacted as if she was delighted to have an excuse to get out of the house and the slightly awkward atmosphere. As soon as the door shut behind her I exploded at Len.
"If you think it will be me that is educating your grandson on Saturday night you can think again."
"Oh don't worry I have been doing lots of thinking about it. I suspect that it has crossed your mind a few times too. Let's just see whether the idea excites you as much as it does me?"
With this he crossed over to me and looked me in the eye with a smile that is best described as lecherous. I was frozen to the spot as without looking down he ran one hand up from my knees until it was very close to the elastic of my thongs.
"If you are dry I will not raise the subject again. Are you dry?"
It was going to be stupid to deny it as I was getting even more excited by the second. I have always become very wet when aroused and my reaction was even stronger than usual. Stupid or not I could not confirm my wetness and just waited until his hand went past my pussy and into the waistband of the miniscule garment. He hadn't got his fingers much past my clit when he sniggered at his finding.
"I think I am entitled to raise the subject of Saturday night given the state you are in. I am a sporting man so rather than argue about whether John should be told about what you have been doing with Jan and me, I propose a little bet. If I can make you have an orgasm in let's say ten minutes - no wait before the clock reaches the hour - you do your duty on Saturday. If I cannot bring you then you can choose where you are on Saturday night."
It was seven or eight minutes before the hour. Surely he would not be able to force me to orgasm that quickly. Within two or three minutes I was far less confident. He started talking to me about what it would be like to be fucked by an eighteen year olds cock. He said at that age he would fuck at least three times in an evening. He said that Jan had told him that Max was well built; I did not need clarification of what he meant. His fingers were tormenting my clit but I was fighting with everything I had to avoid cumming. Many times I had had to fight to orgasm but this was a first time to try and avoid cumming. When he brought his other hand round behind me and found the back of my still present thongs I guessed what he was going to do.
"Just imagine what it would feel like if he fucked you in your beautiful bottom. I think you would cum fast and hard, wouldn't you Lexi my dear?"
It was his words and the images they conjured up far more than the thumb pushing through my sphincter that brought about a crushing orgasm. I thrust my bottom up and down to maximize the pleasure that his thumb afforded my defenseless anus. The fingers on my clit were skilled as the rung every last spasm out of my over-stimulated body.
"Now tell me the idea of fucking Max doesn't appeal just a little bit. You are really the most excitable young lady I have ever met. Be a good girl and refrain from cumming again before Saturday night. You have been very busy the last couple of days. I don't want you burnt out too soon."
I was actually disappointed when Len did not ask me to thank him in one of the traditional ways in such situations. The images that he had filled my head with kept exciting me over and over again until the Saturday evening. I attended the party as Aunty Lexi before taking a taxi to the hotel at just before midnight. Max's taxi was ordered for half an hour later. Max had even asked me why his grandfather had booked a room for him. He had been told that there would be a woman there for him but not much more. As Aunty Lexi I asked him how he felt about the prospect. He said he was very excited but concerned, as he had never done much with a woman. I told him not to worry that I was certain that whoever the woman was she would understand. This seemed to confuse him as much as comfort him as he gave me a sideways look. He moved towards me and I tried to sooth him with a cuddle.
"I wish my first time could be with you Aunty Lexi. I have fancied you for years. Oh I am so sorry it must be the beer talking. But you are gorgeous."
My heart melted and I wanted to tell him that it would be me there and that I would look after him. It was the strangest feeling of sexual excitement mixed with motherly concern. A frighteningly strong mixture.
When I did eventually hear the hotel room door open I felt nearly sick with very mixed emotion. I had convinced myself that I had no option as I had been blackmailed into being here - but who was I kidding? If I had had the option to stay or go right at that moment I would have stayed excitedly. His expression as he realized that it was me sitting on the bed was of questioning surprise followed by him looking round the room as if expecting to see someone else as well.
"Did you come because I said I wanted you to........?"
"You grandfather was very keen that I should be here for you. If you would like me to be your first I would love that too. If you have changed your mind that is fine. If not we can take our time and enjoy anything and everything you would like. Would you like to undress me or would you rather I undressed you? It can be very arousing to take these slowly."
He chose for me to undress myself as he watched from the bed. I tried to make it as erotic as possible but found it didn't take the many minutes a professional artist would manage to make it last. Max seemed delighted by it and his untouched prick was making its presence felt well before I stood right in front of him and told him to take off the one garment, my panties, that I still had on. As he reached out I turned and offered him the view from the rear. His hands were shaking as he slipped them down my legs. Right at that moment I knew that both of us were as aroused as each other. He did touch me even after I turned feeling the dampness, no wetness that I now felt at the top of my legs.
I decided that me taking his clothes of might be more erotic for him than him doing it himself. I laid him on his back and lay next to him. He looked petrified and in an effort to calm him I kissed him on his forehead before undoing his shirt. His prick was making a bid for freedom but remained fully constrained as I kissed his well-muscled hairless chest. I had played with such a sexy chest for years. His groan as by mouth found his nipple was dramatic and I was a little concerned that he might orgasm from this alone. In other circumstances I would have delighted in exercising this total dominance but did not want to embarrass Max. I was also very keen to discover the tool that I would have the chance to play with. There was nothing sexy about stripping him of his remaining clothes until I came face to face with a rather pretty cock. Some cocks are huge, some are ugly this one was neither. I tried to remember whether 18-year-old cocks were always this attractive but couldn't remember that far back. I had been right to be worried about him becoming over-excited. The nearly purple head, that was slightly out of proportion for his shaft, looked ready to explode.
I decided that the only way to slow things down enough for him to enjoy some foreplay was to turn him over and give him a massage. I am not sure it was my best decision that night but he seemed to enjoy it. When I turned him back onto his back his cock looked just as erect and threatening. I brought one of his hands up to my boobs and he latched on to my erect nipple rather firmly. I didn't mind, as any sexual contact with my body would have been welcome right at that moment. When I lent across him to find his nipple with my mouth he was soon using both hands to excite both of my nipples. It lasted maybe as much as 30 seconds of this foreplay that was so beautiful. I had been watching his prick, well more the fascinating head of it, as he seemed to find what I enjoyed him doing with my nipples when his erection eased even further off his stomach a couple of times. I didn't need to hear him say what he did to know that he was going to cum whatever happened.
"Aunty Lexi I am so sorry, so sorry I can't stop it I am going to I am going to....... oh fuck, fuck fuck."
I had moved quickly to take the head of his cock into my mouth and lick the area I know is so sensitive. I rode as his hips thrust up and down as rope after rope of thick hot cum flooded my mouth. I didn't let him push deep into my mouth keeping just the head in it. I thought I would be able to swallow or at least keep all of his cum in my mouth without spilling a drop but had not anticipated the sheer volume. I relaxed my lips just enough to allow the excess to escape as eventually the spasms seemed to be producing very little. His hips kept thrusting well after his orgasm seemed to end but I was happy to keep him in my mouth.
