"C'mon, Jim, just go a little lower."

I was walking past my parents' bedroom one night when I heard my mom say this. I was confused, so I stopped to listen.

"No, Annie, you know I don't like doing that," my father said.

I moved closer to the door.

"You just can't do it for me once?"

"Don't you like what I usually do?" my father asked.

"Of course I do, I just wanted to do something a little different."

I was a little sickened that I had caught my parents fooling around, but I was also intrigued. What did my mom want my dad to do?

"I'm sorry, I just don't want to."

"I'm really clean," my mom insisted. "I just showered."

Then it hit me: Mom wanted dad to lick her ass. Maybe that should've grossed me out, but it actually made me a little horny.

"No, Annie," Dad said.

"Fine, just go back to what you were doing."

When I heard the bed creak, I continued on my way downstairs, suddenly feeling a little weird.

I found mom in the kitchen the next morning. Her hair was disheveled and it didn't look like she had slept well. Now that I thought about it, it seemed as though there were many mornings when she looked similar. Mom was only 40, but now she looked several years older. The fact that she was wearing a ratty bathrobe didn't help.

"You want cereal or what?" she barked at me.

She looked at me, saw my expression, and frowned.

"Sorry, Jason. Didn't sleep well."

"That's okay, mom. Cereal's fine."

After I ate, I grabbed my bag and drove to school. It was a few months into my senior year, and I was itching to graduate. On the ride, I couldn't help but think about mom. I always hated to see her upset. Mom was incredibly giving and selfless and I knew she had a difficult time asking for what she really wanted.

That night at dinner, seeing my parents barely speaking to each other, I decided to do something. When the notion first hit me, I was kind of shocked at myself. But the more I thought about it, the more it excited me. Plus, I told myself, the main reason I was going to do it was to make mom feel good. So, what was I going to do: If you haven't figured it out already, I was going to eat my mother's asshole.

While the whole incest thing crossed my mind, I didn't really think about it like that. I'm not going to lie, the thought of licking my mom's butthole really excited me, but in my mind it was more like a massage, something non-sexual to make her feel good. Perhaps that seems a little naïve now, but it's the truth.

So, how was I going to do it? I had a couple of things in my favor. First, my father was very predictable. After dinner, he would generally read for about an hour and then start watching TV. Somewhere around 9:30, he would fall asleep. Around 11, he would wake up, watch the news, and then go to bed. The second advantage I had was that I sounded almost exactly like my father. People would get us confused on the phone all the time. The more I thought about it, the more it seemed as though I could pull it off. Excitedly, I thought about my plan and decided to put it in action that night.

At 10:00, after checking on Dad, who was asleep, I went upstairs. My parents' bedroom door was open a crack and I pushed it a little and looked inside. It was pretty dark, but from the faint light from the street I could see mom lying on the far side. Luck must've been with me that night because I noticed she was on her stomach. With my heart pounding, I slowly walked into the room and over to the bed.

The comforter was covering most of her lower half and I saw that she was wearing one of her usual nightgowns, this one a light blue. I watched her for a moment and listened to her breathing; she was definitely asleep. I thought for a moment. It sort of defeated the purpose if she remained sleeping, but if she did wake up, there was a real chance I'd be busted. I wasn't sure how to proceed, so I just decided to jump in and see what happened.

I carefully lifted the comforter and peeled it back. Her nightgown was bunched up a little, but it still covered most of her. I was fairly certain she wasn't wearing panties; a few times over the years I had inadvertently gotten a crotch-shot and saw a brief glimpse of her bush. I don't think she had noticed my gaze when that happened, but I remember feeling more embarrassed than anything else.

I reached down and lifted up her nightgown. Sure enough, there was her bare ass. My heart felt like it was going to pop out of my chest. I was looking at my mom's naked ass. It was strange - of course it was, this whole situation was strange - but it was sort of like looking at a foreign object. I knew it was an ass, and my mom's ass, but she rarely wore anything too form-fitting. Occasionally she'd put on some jeans that were a little tight, but that was about it. In fact, it wasn't until that moment that I realized what a great body she had.

Her butt wasn't huge, but definitely on the bigger side. It was round and stuck up quite nicely. I bet it would jiggle very pleasantly, I thought. Suddenly I was aware of my dick straining against my pants. Although I wanted to do this to make my mom happy, I realized how excited I was to do this for myself. I adjusted my dick so it didn't hurt as much, and kneeled down.

After staring for another moment, I slowly reached out my hands and grabbed her cheeks. I quickly looked up at her head, but there wasn't any movement. I leaned in and very gingerly pulled her ass cheeks apart. Though I couldn't see it because of the darkness, I knew I had exposed my mother's asshole and it felt kind of awesome. Still no movement from her, so I leaned in further. Mom always took a shower before bed, so I knew she'd be clean. I could smell soap and a little bit of her own muskiness which made my cock jump. I stuck out my tongue and went in.

I aimed a little too high, but after a second I readjusted and found what I was after and started licking my mom's asshole. I didn't really know what I was doing; I had eaten a few pussies but never an asshole. I had seen it done in a few pornos, so I just did what I remembered seeing. I flicked it with my tongue and then sort of rimmed it. It didn't have much of a taste, but in my mind it was like the greatest meal I'd ever had. I had been holding her cheeks apart for a minute, but then decided to release them. I was engulfed by her ass and it was the most thrilling thing that had ever happened to me. So thrilling in fact, that I didn't realize mom was starting to move.

"Wha? What're you doing, Jim?"

Oh, shit, I thought. I immediately, if reluctantly, removed my face from her ass and quickly got up and moved to the head of the bed.

"Relax, Annie," I said, lowing my voice a little. "I thought about what you said and decided to do it for you."

"What? Really?" She started to turn over, but I lightly held her down.

"No, stay where you are, okay?"

"Uh, okay. You sure you want to do it?"

"I'm sure. Just lay there and enjoy."

I quickly went back down to the side of the bed. Mom, eager for my tongue on her ass, spread her legs. I began again, and this time really went at it. And mom didn't just lay there. She basically humped my face while I licked her. It wasn't long before I felt a hand below me and I knew she was playing with herself. The unmistakable smell of pussy filled my nostrils, and although my tongue and jaw were getting tired, I didn't stop my assault on her asshole. After another minute, mom moaned, relaxed the grip she had on her vagina, and slumped down. I removed my tongue and, after a half-second consideration, decided to take a little lick of her pussy. It was delicious.

"Oh, so good, Jim. Thank you." She immediately fell back asleep.

I fixed her nightgown and the comforter and practically ran back to my room to take care of my dick. With the taste of my mom's ass and pussy on my tongue and lips, I came probably harder than I ever came before.

I repeated my performance the next night, and it went off almost the exact same way: Mom was sleeping, I started working her asshole, she woke up, had a nice orgasm, and then dropped off back to sleep. I of course jerked off back in my room and also went to sleep.

This repeated itself for five nights. And suddenly, Mom was like a different person. She was always happy and smiling, sometimes humming a tune. After the first time, I was worried that she and dad would talk and the jig would be up, but they never did. Maybe mom just figured it was something he didn't want to discuss.

Things went wrong on the sixth night. In retrospect, I should've know something was up. For one thing, I didn't immediately hear mom's familiar steady breathing which told me she was sleeping. But, because I was getting addicted to her ass, I wasn't really paying attention. I went over to the bed and lifted up the comforter. She was naked, which was also new. I only thought about it for a second before I had those cheeks spread and my tongue on her asshole.

After a moment, a light turned on. I froze.

"Why'd you stop, baby?"

Shit, I though. She was never asleep. And she turned the light on? Fuck.

"C'mon, baby, keep going."

I didn't know what to do. My first thought, perhaps not too surprisingly, was, screw it, you're caught, might as well keep licking your mom's asshole while you have the chance. My second thought was, if you get her off, she might just go to sleep like usual. It was my indecision that got me busted.

I felt her twist. "Jim, what's the-"

We made eye contact.

"Jason, oh my god!"

She immediately grabbed the comforter to cover herself. "What are you doing!?"

"Mom, let me explain," I said, though I had no idea what that explanation would be.

"I can't believe you were doing...that." She said.

"Listen, Mom," I said, wondering if I should just tell her the truth.

"You need to get out of here before your father comes back."

"Mom, dad's downstairs asleep, like he always is at this time."

She shook her head. "No, the last few nights he's been here."

I shook my head.

"What are you saying, Jason? Are you saying...the last week...it was you...doing that?"

I nodded.

"Oh my god!"

"Mom, I did it for you."

"What?"

I told her about what I heard when I passed in front of the door that night, and how I wanted to do something for her to make her feel good. I think she could see the sincerity in my face.

She sighed. "It's just not right, Jason. You need to go. We'll talk about this some other time."

I quickly left and went back to my room.

The next day, I avoided my mom as much as I could. After school, I immediately went upstairs to my room. About 6:30, there was a knock on the door.

"Jason, do you want some food?" Mom said.

"Uh, no, I'm okay," I muttered.

She didn't say anything and I heard her go downstairs. About an hour later, there was another knock.

"Jason, can I come in?" she asked.

"Uh, yeah," I said.

The door opened.

"Can I sit?"

I nodded. I was sitting at my desk and she sat across from me on the bed.

"We need to talk about what's been happening, wouldn't you agree?"

I nodded.

"I know what you did, you did for me, but it was still wrong. You see that, right?"

I nodded.

"That's not something a son should be doing with his mother."

"I know mom, but..."

"But what?"

"Didn't it feel good?"

She reddened. "That's... that's not important."

"It is though, mom. I didn't do it to, like, molest you or anything. I just wanted to make you feel good."

She smiled. "You're a good kid, Jason, and I appreciate that, but you see why it isn't right, don't you?"

I nodded.

"Besides, you didn't just do it for me, right? I saw that lump in your pants."

I grinned sheepishly. "Well, I'm not gonna say I didn't like it."

"I thought so," she said with a smile. "But let's just forget it, okay? It's over."

"Okay."

She stood. "Now give me a hug."

I got up and she hugged me. When she ended the embrace, she kissed my cheek. "Come down and get some food if you want some, okay?"

"Sure," I said."

As she left, I couldn't help but stare at her ass. As usually, she wasn't wearing anything very tight, but that didn't prevent my dick from immediately growing.

Three nights later, I was in the living room watching TV. It was pretty later - around 12:30 - so I was surprised when mom entered the room.

"Whatcha watching?" she asked, sitting down on the couch across from me. I couldn't help but notice she was wearing the same nightgown on the night I first went to her room.

"Just flipping around," I said. "Can't sleep?"

"No, not really,"

I had left the TV on some old sitcom and we watched it in silence for a couple of minutes.

"Jason, can I ask you something?"

I turned to her.

"I know we want to forget about...that, but I just wanted to ask you something about it."

We hadn't talked about it again, so I was surprised she brought it up.

"Okay," I said.

"When you were doing that, uh, did you like it? I mean, I know you said you were doing it for me, but did you like it?"

"Uh, yeah, I really did." I felt my penis begin to grow.

"You don't find it kind of gross?"

I shook my head.

"Your father..."

"What?" I asked.

"Never mind."

"Dad said it's gross? Is that why he doesn't want to do it?"

"Yeah, you know how he is, kind of a germaphope. He just thinks it's not very clean I guess."

"But you always shower. You certainly tasted clean." It was out of my mouth before I was able to stop it.

She looked at me for a moment and then smiled. "Thanks. I may not be as much of a clean freak as your father, but I try to keep clean."

She uncrossed her legs, and I don't know if it was done on purpose, but my eyes immediately went to her crotch and I swear I saw a hint of bush.

"I, uh," she started. And after a brief pause, she quickly said softly: "This is tough for me. I haven't been able to sleep for the past few nights, and I know this is so wrong, but do you think you could do that to me again?"

She looked at her lap when she said then, and then slowly raised her eyes to meet mine. By dick was rock solid.

"You want me to...?"

She nodded.

I smiled. "Say it."

"What?"

"Tell me what you want me to do."

"Please don't make me say it, Jason."
