I went up to my room, excited aboutwhat had just happened, I had been asked to check in on Sue, so I oppened her door just wide enpugh to allow enough light into the room, so I coud see if she was ok, without having to put the light on. I saw thatshe had thrown her covers off, so went over to the bed to put them back over her. I saw that her nightdress had been pullud up to just above her waist, and in the half light i could see her little pussy, totally exposed for me to see. I tried to pull it down to cover her up, but not before I had a good look at it, While I was trying to pull it down, she moved a bit, so I stopped, she had opened her legs a little, and now I could see the outline of her pussy lips, I was so hard by this point. I would love to have touched her, but thought better of it.

I finally managed to get her nightress re-arranged, and got her covers back over her, then I slipped out of her room and went to my own. 

I got undressed and jumped into bed, my cock was still hard from what had happened with Mum, and with what I had seen of Sue. I started to wank slowly, trying to recollect what I had seen of Sue, but it was what had happened with Mum that kept coming into my head. 

I poured myself a vodka, I wantedto try to numb myself a little, so that I wuld not cum too quickly. I turned on my tv, and put ona set of headphones, as I did not want to disturb anyone. I was watching some music show, there was a female band on all wearing sexy outfits so I started to stroke myself again, it felt good, my hand rubbing my cock, I could feel my precum seeping between my fingers, I closed my eyes and tried to imagine what it would like to be with one of the band members.

I was really getting into it, when I felt a hand on my leg, please God, dont let it be Sue, I opened my eyes and saw my Mum standing beside me, she was wearing a short silk dressing gown, which was open, revealling her full breasts, her nipples hard, and her shaved pussy. She had one hand on my leg, and the other was stroking her pussy. She sat on the bed next to me, then took off my headphones, and quietly asked me if I wanted her to rub me again. I said I would love her too. 

We both sat on the edge of the bed, side by side. she reached over and grasped my hard cock, it felt so good, she told me to feel her.After a couple of minutes of me rubbing her, I could feel that she was about to climax again. She did, then she stopped rubbing me, Mum then turned to face me and said thank you, I asked what for, she said for getting Dad hard, she said that it had almost been 4 years since they had sex, as he could not get it up properly, and that when they had gone to the bedroom, he only just managed to stay hard enough for him to cum. She told me that he had said that he was so turned on watching her with me. Mum suggested that next time, we go to their bedroom, and she will rub me, and when he is hard enough, he will have sex with her, while she strokes me. I said that it sounded strange but would think about it.

Mum then asked if I would like to finish myself off, having sex with her, I said no, the thought of being in there when Dad had just cum, was just too strange. She told me she knew what I meant, and asked if there was anything else she could do for me. I suggested that she could suck me, then realised what I had just asked my own Mum to do, but she said ok, and told me that she had not sucked a cock sine before she was married, apparently Dad did not like it. She told me to lie on the bed, and knelt at the side of the bed, so I could play with her boobs and pussy while she sucked me. She took the tip of my cock into her mouth, and licked it all the way round, before taking the full length into her  mouth. I was playing witth her boobs with one hand, and wis sliding my fingers of the other deep into her wet pussy.

I knew that I would not last long, Mum was a great cock sucker, the way she licked and slid it in and out of her mouth. I told her I was about to cum, but she started sucking it harder, then I exploded my hot cum in her mouth, she kept sucking until I had finished cumming, then she swallowed it all down. 

She then got up and sat beside mt, she told me that she had oved it, and hoped that she could do it again. I told her she could and that it was probably the best blow job that I had ever had.

She got up and put her dressing gown back on. As she was leaving my room, she said thank you, again, and that she was happy that I had moved back in. She then asked if I could do her and Dad a favour, I said sure, what was it. She said that they had to go away on Friday for a couple of nights, and asked if I could look after Sue. I said sure, no problem !!!
