I once had a girlfriend who really got off on having sex while she was on the telephone. At various times we fucked while she talked to her mother, her best friend, her brother-in-law and her husband (he was away from home for months at a time). This was in the 1970s and she had just one phone in her apartment, in the kitchen with one of those long ass cords. So we would usually fuck on the kitchen floor. I really got off on that kink she introduced to our sex life. Fast forward about 20 years when I was having an affair with my wife’s best friend. Wife called from work one day as my lover and I were going at it hot and heavy. I got up to answer the phone and brought the phone back to bed to talk about whatever the hell my wife wanted to talk about. My super horny lover started sucking my cock while I was pretending to follow what my wife was on the phone talking about. Then, my fuck buddy decided to ride me and absolutely fucked my brains out. I have no idea, to this day how I kept my composure. I found an excuse to cut the phone call short. My lover and I fucked like wild animals and both exploded in orgasm. The naughty fun while on the phone made us extra horny. I returned the favor a week or so later and fucked her while she was on the phone whispering sweet nothings to her husband.
I try to mess with the wife when she is on the phone, it has only worked enough to fuck her while she talks maybe twice, but it is super hot!
One time my married lover had a long conversation with her husband as she slowly rode me deep and hard. She rang off before she ground hard for a couple of seconds and then came before lifting herself up a bit so I could feel myself entering her and I came hard in her as well. She never said why she called him that time, we never did that again but it was a happy memory. She was just looking at me and once or twice just put her fingers on her lips to tell me to keep quiet.
