I glanced into my son’s room as I walked past and saw he was masturbating. I’m not sure I’ve ever done a double-take before, but I walked another two steps before I stopped, my head snapped up, and I walked back to his door.

“What are you doing, Ethan?” I asked, although the answer was obvious.

“I’m masturbating, mom,” he said, as though it was a perfectly normal thing to be doing. Well, I mean, it is perfectly normal, but not in front of your mom.

“You, uh, should close the door when you do that,” I said.

“But then you wouldn’t see me,” he replied. “This is actually the fourth time I’ve masturbated with the door open, it’s just the first time you’ve seen me.”

He continued to stroke, although a little more slowly, while we talked. Actually, I was somewhat dumbstruck and said nothing further for a while. I took a step inside the door.

It was around ten o’clock at night. Ethan lay naked on the bed, his shoulders propped on a pillow, and his reading lamp shining down on his chest and cock like a spotlight. His balls were somewhat shadowed. That I could see my son’s hard cock and balls amazed me. It also aroused me a little.

I took another step forward and Ethan tugged more quickly at his cock.

“I was close to cumming, mom,” he said matter-of-factly. “I’m getting close again.”

“You wouldn’t,” I whispered.

In answer, his hand speeded up further, focusing more on the end of his cock. I watched his balls tighten up and he breathed more quickly and he came. A jet of cum splattered his chest, a thick rope of white cream shot from his cock. A second squirt blasted almost as far, then more cum streamed shorter distances. A few final drips flowed over his hand and balls.

“Oh, my god,” I said. “Shit, Ethan!”

“Pretty good, huh, mom?” he said catching his breath.

“But why ln earth did you want me to see it? Why did you want me to watch you?”

“I can’t really say, but I enjoy being watched. Sharing the moment, maybe. All I know is that it turns me on. Especially with my mom.”

I might have blushed. “You’ve done this in front of other people?”

“Oh, yeah. Many times. I probably masturbate three times a day, which you’ve probably noticed, what with my cum on the sheets and pillowcase and socks and underwear and towels and sinks and shower and, well, everywhere. I masturbated in front of Chrissy and Mia. I’ve cum in front of Mrs. Elkins, although it was outside her kitchen window at night, when she was doing the dishes, and maybe she couldn’t see me. In front of cousin Eleanor. I even did it once in the showers at school, but I’m not certain any of the guys were actually looking and doing it in front of guys isn’t the same, anyway.

“That’s… awful,” I said. It was at least impolite. Well, it was impolite unless they actually enjoyed watching, which, now that I thought about it, maybe they did. I know I loved seeing my son cum, not that I’d say so.

“Well, stop it. Stop masturbating in front of everybody. It’s not normal,” I said, a little unsure of myself.

“Maybe. Anyway, I’m done for today.” He rolled over, turned off the light, and pulled a sheet over himself.

I stood in the darkness for a minute. I should probably have scolded him further. It was just the two of us living in the condo, Ethan being the only child I’d had with my ex. My ex had enjoyed masturbating in front of me, too, but I thought he was just a little odd. He also enjoyed fucking me in the ass, which I kind of liked, but only sort of. And he’d peed on me once. Perhaps I was the odd one. With that final thought, I left the room, leaving his door open, and finished walking to my room, where I closed the door. I undressed, brushed my teeth, got into bed and masturbated myself to sleep.

The next night was much the same, although I watched Ethan masturbate longer. I suspected that he’d waited for me before beginning. His hand slid up and down his cock and he felt his balls with the other hand. Two minutes later, his eyes closed while masturbating but open at the end, he was cumming all over himself again, grinning.

I masturbated that night and thought about it afterwards. Why was masturbating such a private thing? Well, sex is private, and masturbating is a little like sex, so maybe that’s it? Although a fair number of people, I had no idea how many, have sex with more than one person in the room, so maybe not? I couldn’t honestly think of a single reason why it should be such a secret thing, just that it was.

The next night, I walked right into Ethan’s room and stood by the bed. I was dressed normally for the end of the evening, just a sweatshirt (no bra) and jeans (and panties), my feet bare. Ethan was, of course, totally naked with the sheet and bedspread pulled down. His cock was hard and pointing straight at his chin as he lay in bed. I sat on the edge of the bed.

“Go ahead,” I said. “I’m ready to watch.”

He scooched over toward the wall and said, “Lie down, mom, you’ll feel more relaxed.”

I was skeptical, but I lay on my side, facing him. He was still on his back and his dick was in his hand. He began stroking himself very slowly. I had no idea what he was thinking about.

“What are you thinking about?” I asked.

He blushed! Here I’d thought he was a mad masturbator, but he was still at least the somewhat shy teenager I loved so much.

“I don’t have to say, do I?”

“Well, no, I guess not, but what kind of secrets could you have if you’re happy to jerk off in front of your mom?” I paused. “Wait. Let me guess. You’re thinking about getting a blowjob from that girl you went out with who has the big boobs. Um, Cherise?”

“Chrissie. No, mom, I wasn’t thinking about her.”

I put my hand on his bare chest.

“You’re thinking about a handjob from Barbara. She had smallish boobs, right? But she was blonde, so that would make up for it,” I joked, being blonde. “I know it’s her. Her strokes match yours in your mind’s eye. Tell me I’m right.”

I rubbed his chest in small circles.

“No, mom, quit asking.”

I made a pouty face and looked at his hand, which was rubbing his cock a little faster.

“Give me a hint?” I asked.

“OK, I’m thinking about an older woman who I’ve never had any sex with. Except in my mind.”

His English teacher? She was kinda cute. I didn’t know all his teachers, but most were men. Principal Sweet? She was almost forty, too old, I figured, although that was how old I was.

“Give me another hint?”

His hand quit stroking and he looked at me instead of the ceiling.

“I’m thinking about you, mom. I mostly get off imagining I’m having sex with you.”

I expect my eyes widened, that I blushed, that I bit my lip. I breathed a little faster and stopped rubbing his chest. You know how they say “time stopped”? It was like that.

“Really? You mentally have sex with me? I’m… naked?”

“Totally, mom. Bare breasts, bare pussy, bare ass. You’re beautiful, you know.”

I would have blushed a redder red if that were possible. How could Ethan talk like this?

“Well, stop it, jerk off to Cherise. Cherry. Whatever her name was. Is.”

“No, mom, I can think whatever I want,” he replied. Ethan smiled and looked at the ceiling again. He began to masturbate again and I knew he was thinking about fucking me. I started to tell him again to stop it, but I didn’t. I rubbed his chest, not really looking at his hand.

What was so wrong with fucking your son, I asked myself. Besides everything, that is. I loved him, but not as a romantic partner, although I’d fucked men I wasn’t in love with… just about all of them, really, had been about sex and not especially about love, although sex was often the least of it. Ethan could get me pregnant, even though I was on birth control, but it was really unlikely and it was fixable. He was certainly attractive enough, although he was younger than anyone I’d had sex with in ten years. Twenty years. Still…

I felt Ethan’s breathing suddenly increase and I looked to see his tummy moving up and down, his hand moving quickly on his cock and he shot cum onto his chest and my hand. I thought I could actually hear it shooting out of his dick. First, a long stream that almost hit his chin and streaked the back of my hand. Another just as long, followed by two more almost as big, a whole lot of cum. Finally, two more small squirts, followed by a dribble. I smacked his chest and wiped my hand on his shoulder.

“Good night, Ethan. Sleep well.”

 I didn’t trust myself to say more than that. I looked at his cock one last time as it shriveled in length. Cum streamed down his side.

The next night, I walked into his room wearing just a pink heather, fleece robe that stopped just short of my knees. I had thought about it and while we wouldn’t have sex or anything, I thought it would be OK if he saw a little more of his mom’s skin. I was naked under my robe, Ethan was simply lying naked on the bed, waiting. But he was thinking about something sexual, maybe me again, because his hard cock throbbed. I tried not to think too hard about my son getting off thinking about his mom. I lay on my side next to him, my robe cinched tightly so he couldn’t even see any cleavage, although he could see my legs to my thighs.

Ethan began to masturbate, just stroking his cock as usual. He’d been going for maybe a minute when I casually raised my hand to brush my hair away from my eyes and just as casually pulled my robe open to entirely expose a breast as my hand returned to my side.

Ethan stopped masturbating. He looked at my boob for a long time before looking at my face. Then his eyes went back to my breast.

“Do you want to touch it?” I asked.

He didn’t say anything, but he reached out and squeezed a nipple, much too hard, although I didn’t flinch.

“A little more gently, please,” I said. “Like this.”

I rubbed one of his nipples between my thumb and forefinger using a soft touch. I brushed my palm against his nipple, I used my fingertips. I heard a quick intake of breath. He started to masturbate again.

I leaned over so my nipple was right over his mouth. His head came up and Ethan began to suck at my breast. You’d think that would remind me of when he was a baby, but it didn’t, it turned me on. I could feel myself getting wetter, although for what, I wasn’t sure, but a little juice dripped down my leg. My position wasn’t totally comfortable, but I loved the feeling of his lips and tongue on me, I loved watching him jerk off. Shit, I was losing it.

I pulled my robe down to my waist so I was naked on top.

“Don’t stop, Ethan. Keep masturbating. Think about sex with your mom. Sucking her breasts. Playing with your cock.”

I moved slightly and gave him the other nipple. His hand jerked faster. His tongue licked the underside of my boob, which made my muscles clench and my body gave a long shiver.

“Oh, mom,” he said, somewhat breathlessly, “oh, mom.”

He licked my nipple and he came. It didn’t seem to take much for him to cum. More long blasts, the second of which hit my boob.

“Cum for me, Ethan. Cum on your mom, cum on yourself. Fuck your mother with your big, fat cock. Cum inside me, cum anywhere you want. Oh, Ethan, I love you so much!”

His ass had raised off the bed as he came, but no more of his cum reached my bare skin. He got a little on the robe. I couldn’t believe I’d said what I said.

“Shit, mom, that was… I don’t know. Awesome. Erotic. So nice. So fucking nice!”

I reached down and lightly touched his softening dick. I thought about what to say and gave up. His cock transitioned from a hard weapon to a thin, limp noodle. Almost without thinking, I leaned over and kissed it.

“Oh, mom, shit.”

I ignored his swearing. I kissed it again and again, tasting his cum. I took the limp noodle into my mouth and sucked, thinking of that scene from Devil in the Flesh. My fingers wrapped around it and I licked the end. I looked up at him and smiled, then returned to licking and sucking his dick. I licked the short length of it, pressing the tip against my cheek. I felt it begin to harden.

Oh, fuck, I thought. I hadn’t expected him to get hard again so quickly. I sucked him a little harder and rubbed his balls. It took almost a minute, but his cock got totally stiff again.

I’d slid down on the bed to suck him better, but now I was falling off. I didn’t let go, but I turned myself around so my knees were at his head. My robe must have fallen open, because I felt a finger at my cunt.

This was totally wrong, but here we were. I sucked his cock some more, paying attention to the tip and also to what was happening between my legs. I put a hand under his tight butt. I remembered when my ass was as firm as Ethan’s.

At first, it was just a finger sliding up and down between my labia, but not really penetrating me. Then, two fingers, up and down. I felt them probing, looking for the way in, which they quickly found. I was so fucking wet. I felt more cunt juice sliding down my thigh. Ethan’s two fingers weren’t accomplishing much, though, so I swung a leg over his head and presented him with my sloppy cunt directly in front of his face. I sucked him some more, jacking him with my right hand.

I felt his tongue poking around. He licked my slit, but he didn’t really get to my clit. I shifted my hips a bit and his tongue did touch my clit, giving me a jolt of electricity that quickly vanished. I lifted my head and began stroking him seriously. I jerked his cock up and down, while using my other hand to stroke his balls. Roughly every fifth stroke I would put the tip of his cock between my lips and suck for several seconds. His tongue found my clit again and actually stuck around for a bit. I think I moaned. I was jerking his cock when he came for the second time.

It wasn’t a huge load, but still enough to streak my cheek. I opened my mouth and pumped his dick. He ejaculated near my mouth, but no cum actually made it there, it just covered my chin and a little got in my hair.

“Oh, my god, mom, that was so good,” he said into my cunt. “You are the very best.”

His warm breath on my cunt made me shiver again. I detached myself, turning back so we were face to face, hip to hip. I put my hand on his small, soft dick and just rested it. Ethan lay back as though he was exhausted. Maybe he was.

I wasn’t. I was eager for real sex and it was obvious I wasn’t going to get any. I figured I’d wait a few minutes to be polite, then go to my room and masturbate like crazy. I expected to cum in just a few minutes, thinking about Ethan’s cock in my cunt.

As though he could read my mind, Ethan said, “You know, you could just masturbate here.”

“What!” I said much too loudly.

“Well, you’ve watched me, multiple times. You’ve jerked me off yourself. There’s no reason why you can’t do yourself in front of me. I’d, uh, kind of like to watch.”

I didn’t know what to think. Ethan could masturbate in front of me, but I couldn’t do it in front of him? That didn’t sound right. And, shit, I was soooo horny. I looked at his cock and sighed, as it certainly wasn’t getting erect any time soon.

“Just rub a nipple, mom, start slow,” he said.

Ethan actually picked up my hand and put in on my breast. He massaged it so I would feel my boob and my breast would feel me touching it. He let go and I continued to rub, fingering my nipple. I felt a slight, sudden jolt and I pretty much lost any control I had. My fingers went from fucking around to serious about masturbating.

I closed my eyes, as I wasn’t really ready to be watched while I did this. Eyes tight, my hands eased down my body to my cunt and back up again to my nipples. I brushed them lightly, then let my fingers wander over my breasts and my tummy and the skin in between. It was like lying on the beach on a lazy afternoon, not trying to accomplish anything. My fingers floated to my nipples again, circled them a few times, then made their way to the top of the little pubic hair I had.

I just realized you might be wondering what I look like. Well, I’d say average for forty-one years old, but that doesn’t tell you very much. Let’s see. I was suntanned everywhere except for what my bikini covered. My face was somewhat narrow, at least not fat. My eyes were hazel and kinda far apart,...
