Phone Sex With a Difference
 

This may be quite tame but here goes. If one of my wifes friend calls her on the phone and I know they are going to talk for some time I get my wife to sit on my face and I suck her pussy while she is talking.
I takes a while but eventually I can make her cum, she has to be dead quiet so that her friend don't know what we are doing and normally she will hum and ha a lot just before an orgasm.
We have done this with at least 4 or 5 different friends many times (all female) and I don't think any of them have known ;)

Knicless, I for one would love to hear about the other 4 or 5!! It would turn me on more if the friends did know.....

i have seen an movie
where the wife is fucked (cheating) while calling her husband

or

she let the phone open while fucking another man while her husband is listening.

have you ever heard people fucking in an motel?

Do this all the time. Some examples are.

Spoken to my GF while balls deep in my FB, GF thought I was doing work (I kind of was) and as I was fucking her I was on the phone looking into my FB eyes saying things like "Yes its proving really hard but I can do it. I thought it was a one man job but now I am doing it I think it will be a two man job"

As luck had it I had arranged for a mate to join in for a threesome so left them to it while I finished talking to GF.

FB also called her husband so he could listen.

Met a few couples and single guys and they have been willing to call people while fucking or being sucked by my FB.

They have called, wives, gf's, work, bosses, family, friends one chap even called a customer service :)

My favorite was a guy who cum inside her while on phone to his pregnant wife, everyone had to stay really quite. He made some excuse about sneezing lol
