Masturbating my wife

One of the things I have always enjoyed most about sex is making women cum with my fingers. It is something that I got to be really good at from quite a young age, unless lots of women tell every guy he's the best they have ever had at doing that, which I guess is possible! I'm not an ego maniac btw, some things I am better at than others, I can't fuck a girl for 30-40 minutes like some blokes can, but I think hand jobs are the bit I am best at! With my wife, I made her orgasm on our very first date and she did the same for me. We didn't go all the way, but she came back to mine and we got into passionate kissing, then me sucking and kissing her tits, before we were both between each other's legs. I was sucking her tits while fingering her, taking the wet from her cunt and rubbing it over her labia, then her swollen clot, which was rock hard. I remember her gasping and she told me later I got the pressure and friction just right, rubbing her in tiny circles, speeding up with her breathing, till she exploded and so did I, all up her arm. As we got to know each other better, she has loved it when I talk dirty or share a fantasy while masturbating her. Sometimes I might tell her to visualise a guy she is hot for and imagine her is doing it, sometimes I might get her to recall some of her favourites sexual experiences, sometimes it is more elaborate, like she is a policewoman guarding a prisoner who 'persuades' her to let him go or I am a stranger sitting next to her on the train who is secretly pleasuring her (and sometimes she returns the favour). These scenarios make her really hot, she usually chums within 5 minutes of me touching her cunt, so they are usually also quite brief! More recently still, she has taken to masturbating in front of me while I tell her stories or she recalls things. The horniest example was when she told me about a guy we both knew who she had a one night stand with. It was before we net and I didn't know. She told me how he had a really big cock and went down on her for ages and it was the first time she had ever cum from oral sex. Also that she put her tongue up his ass while wanting his big cock. She said that of all the guys she has fucked, nobody apart from me made her cum so easy and that she came maybe 5 or 6 times with him, including from fucking his cock. I don't know why this turned me on so much, but she was masturbating and panting as she told me and admitted she still masturbates alone to that particular memory. Now, of course, I do as well! I think my very favourite thing about making her cum is that she really moans and talks filthy as she gets close, telling me to rub her wet cunt, telling me how she loves the feel of my cock in her hand or saying that she wants other people to fuck her. It's very hot to make her lose control like that. Sometimes she is a bit embarrassed after, especially when she thinks she has gone over the top, but for me it's such a turn on. I love love love touching her cunt and the way it makes her feel.
