My husband and I had been trying to get pregnant again for some time now. Our son was getting older and would be leaving home in a few years, and we wanted another child before then. Unfortunately, though, it had been about three years of attempts, and I still wasn't pregnant. I was getting rather frustrated with the whole process because sex just wasn't fun anymore.
One morning in the shower, I was lamenting my lack of a good, hard fuck and remembering what our sex life was like just a few years before. I admit my memories were getting me horny, and soon my hands were wandering over my slippery, soapy flesh, squeezing my breasts and pinching my nipples and then wandering down to caress my pussy. I had just let one finger slide between my lips to touch my clit when I heard the knock on the door.
"Hurry up, Mom! I really have to go!"
It was my son, Nick. I didn't want to get out of the shower yet, so I just did what I always did in these situations.
"I'm gonna be a while, Nick... just come in and go to the bathroom quickly."
The door opened when I was only halfway through this statement and I heard him sigh as he finally relieved himself. My level of arousal was such that I suddenly had an overwhelming desire to see cock, any cock, and so I peaked around the shower curtain to look at what my son had. He had just finished and was shaking off the last few drops and I could see that he had a nice one, even flaccid like that. He gave it a couple of quick strokes and it grew a little bit, but then I tucked it away and washed his hands, leaving me in the shower, even hotter than I had been.
I closed my eyes and leaned against the wall, two fingers quickly plunging into my aching pussy as I thought about Nick's cock. My tongue poked out and licked my lips as I wondered if he'd had a blowjob yet. I pinched my nipple as I remembered him suckling my milk as a child. My fingers pounded into me hard and fast as I imagined what it would be like to feel my own son's cock fucking me. I came so hard and fast that I almost fell and then breathed hard for a few minutes, considering what i'd just done.
I got out of the shower and dried off, wrapping the towel around me and opening the door to go back to my room. Nick was just coming out of his room to go somewhere, and I pretended not to notice him as I let my towel slip down to reveal a breast. Then I opened it up partially, revealing flesh all the way up my side, and closed it again, only then taking note of his presence. His face was flushed and his eyes were travelling up and down my body and he had to shake himself when I asked where he was going.
"Uhh... oh yeah. I'm heading over to Tony's for a bit" he said, finally.
I told him to have a good time and to call if he were going to miss dinner. He nodded vaguely and adjusted his half-hard cock in his pants as I turned to go into my room.
I lay naked on the bed, incredibly horny from having just flashed my son, and I had to fuck myself again. This time, though, fingers wouldn't do. I reached into the bedside table and took out a large dildo, licking around the tip a bit to lubricate it before putting it at the opening to my pussy and slowly pushing it in. I moaned after the tip entered me, pausing before sliding in some more and then easing it out. I did this a few times until I had the whole thing buried in me, then started to speed up my fucking, pretending it was Nick's cock in me, stretching me and filling me. Again, I came hard and fast, this time moaning his name softly under my breath. I wanted him.
