My Wife Chats With Her Sister On The Phone When We Have Sex

A few months ago, my wife and I were having sex. She was on top of me when her iPhone rang. It was her older sister. I figured we were done, but my wife didn't move. She stayed on top and kept right on talking. At one point in their conversation, my sister-in-law asked my wife why she was breathing kind of funny. So she told her what was going on. I could hear the shocked expression from my sister-in-law, who is in her mid-60s and a widow. But they kept talking with my wife giving a brief description of what we were doing. Eventually, the phone call ended and we continued having sex.

Later, my wife said her sister wants her to call her the next time we're having sex. Sure enough, the next time we had sex, my wife calls her sister. This time, I'm on top, thrusting into her. She tells her sister what we're doing and midway through the call, she has an orgasm while on the phone. We switch to doggie and my wife tells her sister what's happening and then has another orgasm, as do I.

We've done this several times now. I asked my wife if her sister is turned on by this and she says yes. She's pretty sure she is masturbating during these calls. I asked her if she wants to Facetime with her sister the next time we have sex, and she said she would think about it.
