Her next Orgasm

I woke with J by my side, it was 5.30am and my bladder was telling me time to get up! I went along the landing to the bathroom, naked as we were the only two in the house, or so I thought!
I finished up and was heading back to the bedroom when J's youngest daughter appeared.
M was 23, single Mum, and J looked after her grandchild most days while M was at work.
We both stood there, me naked, M fully clothed. I backed up, turned around and headed to the bathroom. M was giggling, said something like 'well that's a nice way to start the day'. I grabbed a towel, wrapped it round my waist, went back on the landing and with a big smile on my face said, 'good morning I wasn't expecting anyone'. Obviously M replied.
M was a larger lady, size 18 I guess, big mop of black hair and over did the make-up.
She smiled and said, I hope you're looking after Mum, in every way? Of course I am, I replied not picking up on the innuendo! M giggled again, from what I saw I'm sure she's enjoying herself.
I went back in the bedroom, grabbed my clothes and headed back to the bathroom to get dressed. M went downstairs and made coffee. J was fast asleep.
M had dropped her daughter off, earlier than normal and was going to go to work in a couple of hours. We sat at the kitchen table, 05.45, drinking coffee and chatting.
M wasn't backwards in coming forward and started to question me about sex with her mother. She told me she knew I would be only her second sexual encounter, that she knew nothing about sex. I sat quietly while she continued to tell me about her parents relationship. I'll not go into detail but it must have been terrible for them all. M asked me to take my time with her Mum, treat her nice. I tried my best.
I continued to see J every couple of days, not always staying over, not always having sex. I was trying to build a solid relationship. I was falling in love, I wanted to be with J more and more.
One evening she surprised me, told me she'd been watching porn. How it shocked her, how if frightened her. I asked her to show me. OMG she'd found a full on bondage site, even I couldn't watch it. I found some 'standard' porn. We sat watching together, J was open eyed at a women riding her man, bouncing up and down, huge tits flying in all directions. I could help but smile. We watched a 'plumber in the kitchen' film. J started to ask questions. Is this normal, how can you sit on a man like that without knowing him, why would, how do they etc etc.
They're trying, badly, to make a story out of it but basically you're watching two people have sex. Like I've said before sex can be done anywhere. Come with me. I led her into the kitchen. Asked her act out what we'd just watched.
She laughed and said I can't do that. You can, come on follow my lead. I opened the sink cupboard emptied it out, laid on my back and shuffled my head and shoulders inside.
I asked to take her slippers off, play with my crotch with her feet, just like the film. Slowly, she complied. Rubbing my groin with her feet, feeling my cock get harder. I told her to take my trousers and pants down, play with my cock, suck it. She stopped. I can't do that, put that in my mouth! You can, try. She started to touch me, felt me getting hard, I told to cup my balls, my cock hardened. She started to get it, the more she played the harder I got. I let her carrying on playing, wanking me slowly, precum on her fingers. I suggested she lick her fingers, she did, stroked me some more sucked her fingers again and realised that a blowjob wasn't going to so bad. She was gentle, but no idea of what to do. I tried to coach her, explain how to move, when to gently suck.
The back door flew open and in walked M. There we were, role playing the plumber getting fucked by the bored housewife and in walks the daughter. J screamed, out, get out. M said oh Mum I've seen him naked, and I can see a bit more of him now. They then had a brief conversation on how J can give a better blowjob. I was still laid there, cock not so hard! I started to move, J said stay there. Then she said, show me, show how I should do it.
The next thing I know is my balls are being fondled, my cock is in a hand and I'm thinking, hang on who is doing this. Wow, hang on ladies, what's going on. M replied, I'm going to show Mum how to do it, you're going to lay there and enjoy it. J said, I need to learn, need to know how to do this properly. Let M show me.
I laid there, balls being squeezed, cock being stroked and then taken inside a mouth. M knew what to do. Every 10 seconds or so she'd stop explain to J what she was doing. After a couple of minutes of M, she told J to try. It was better but no where as good as M. We both suggested things, but J wasn't happy. She stood up and said, show me again.
M started again, my shoulders now starting to ache. I asked to be able to lay flat on the floor. Having moved I could see them both, M had her hand inside her trousers, J sat on a stool watching. I was rock hard.
M went to work on me, by now I didn't care who had my cock I just wanted it. I stopped M for a moment, suggested she got naked so I could show J what could happen. M checked with J, who was now rubbing herself through her dress and knickers, a simple nod was all M needed. Her top came off, bra and quickly followed by her shoes, trousers and knickers. She had fabulous tits, and considering she was a larger women had a good body. She knelt down grabbed my even harder cock and wanked me to near cumming. Meanwhile, I'd found her clit and was playing with my fingers, she was so wet. There we were, daughter and mothers lover showing the mother how two adults can enjoy each other without knowing them.
M asked if she could finish me off, I said only after you've cum. Let me suck on your clit. She sat on a chair, spread her legs and said go for it. I didn't need any encouragement, I was licking and sucking, fingering, squeezing her ample tits. She came quickly, let out a long moan of pleasure. I kept going, my head was pulled tighter in, I gasped for air and M pulled me back. She was having a second bigger orgasm. She was shaking, body twitching. I looked back at J, her hands inside her knickers, head back masterbating. I shuffled across the kitchen, kneeled in front of her, pulled knickers to one side and ate her pussy. She came hard, nearly falling of the stool. I stood, looked at these two very different ladies in front of me and thought, now what? M was on her knees, took my cock in her mouth and finished me off in seconds. She tried to swallow it but there was just too much cum. It ran down her chin. I scooped some off and offered it to J, she took it, not sure she liked it but swallowed as M had.
All three of us ended up on the floor, all in a different state of undress. M broke the silence with, thank fuck I'd just dropped (daughter) at her dad's before coming here. I said, it would have been terrible if she'd walked in on Nanna sucking the plumbers cock. No, I wouldn't have been able to enjoy the last 20 minutes!
We all dressed, M got what she needed and left. J and I got a glass of wine, sat on the patio and discussed what had just happened. J was buzzing, didn't realise how sex could be fun, exciting even. I did say that M being involved in such a way may complicate things but J was insisting that M helped her, show her how to make love properly.
I couldn't wait! I went home that evening with a huge smile on my face a large bulge in my pants.
