Phone Sex Masturbation

My last 2 years in the Air Force, I got stationed close to where my wife and I grew up.  It's a little Podunk town that most people don't want to be stationed in, so when I volunteered for it, I got it. One Saturday, my wife went to visit some of her high school friends for a baby shower or something like that. I was at home alone just watching TV and reading.  My wife had been gone about 30 minutes, enough time to get to the friend's house, and the phone rang.  The caller ID had no name, and it showed a local number, but not the town where my wife's friend lived. I answered, and a female voice said "What are you doing?" "Not much.  Who is this?" "You don't know who this is?" Flirting, with her voice sounding sexier all the time. "No, I don't."  I figured this was someone that my wife had gone to school with, and had asked her to call me as a prank. She kept on asking if I was sure I didn't know her, and I kept thinking that she would admit it was a prank that my wife started.  But she didn't. This went on for a minute or two, and I kept asking her to please tell me her name, but she never did. Then the conversation got a little more heated.  She asked what I was wearing.  "Jeans shorts and a t-shirt."  She said "Want to know what I'm wearing?"  I figured I'd play along, still figuring it was a joke call, so I said "Sure, what are you wearing?"  "Just a bra and panties and nothing else.  And I'm sitting here on my bed rubbing my titties while I'm talking with you."  OK, then. And I'm starting to get an erection. "So why are you calling me?" I asked She said "Because I'm horny and want to have some phone sex. Would you like to do that with me?" What could I say but "Sure'" By then, I was certain that this wasn't something my wife had set up - she wouldn't go that far with a prank, and I figured this to be a either a random phone call or someone that knew us.  But the gal on the phone didn't sound like anyone I knew or worked with either. She said, "Wait a second, I want to get my vibrator out of my dresser drawer", and I heard her lay the phone down on the bed.  This made my cock get even harder. She came back and said she was laying back on her bed and was using the vibrator on herself. Sure enough, I could hear the buzzing start and she said she was rubbing her nipples with it. Then she started moaning and telling me how she was fucking her pussy with the vibrator.  I had no idea what she looked like, but at the time she sounded beautiful and sexy.  She had a nice, sensuous, horny sounding voice.  I was sitting in my living room chair, listening to the buzzing vibrator, and her telling me that she was fucking her pussy with it.  By then, I had a really stiff hard-on, so I pulled open my pants to free up my cock, and started wanking myself while listening to her.  She kept moaning, and I could hear the sound of the vibrator getting louder and then muffled and then louder again, and in my mind I could picture it sliding in and out of her pussy.  After a couple of minutes with her moaning, and me wanking, she started saying "Oh, oh, oh, uhh, uuh, uhh..." and then "I'm cumming, I'm cumming!" I'm listening, not saying anything, just breathing hard into phone, holding it with one hand and jacking my cock with the other, expecting that she'd talk me into my own orgasm. Then, suddenly - "Oh, shit - my husband just drove up.  I gotta go!" and she hung up the phone.  I was too far along in my wanking process to stop, so I put down my phone and then I jerked faster and shot my cum load onto my chest and stomach, several strings that faded into a glob of cum running down my cock. I stripped off my jeans shorts and my underwear, and used the underwear to wipe up the mess.  Then I went and put my underwear in the dirty clothes hamper and took a shower to clean up.  But, remembering what had just happened, and the hotness of that phone call got me horny again, and I had to have another wank and cumshot in the shower. For a couple of days after that, the phone would ring.  If my wife would answer, the person on the other end would hang up without saying anything.  Every time when I answered and it was her, my wife was at home with me. The girl on the phone would use that sexy voice and ask if I could talk, and I would say "Wrong number" and hang up.  Finally she quit calling. I never knew who she was, just guessing she was horny and got off on trying to have phone sex with random guys.  Since we lived in a military town, she may have been home alone a lot and wanted to get her jollies anonymously. That's the only time I've ever had phone sex with anyone other than my wife.  But it was an interesting one-time event.
