The way it began was kind of unusual. My name is Phillip, I'm eighteen, and I live with my mum, who's in her late forties. One day I was in my room, completely naked, in the process of getting dressed. I was standing in the middle of the room, dick hanging out in the open for anyone who came in to see, when the door suddenly opened, and my mum came in with a basket of laundry. Immediately I blurted out, "Jesus, Mum, knock!"

"Oh, Jesus, sorry, Phil!" My mum immediately backed out again. "Don't worry, I didn't see anything."

She said this, but somehow I knew she was lying. The look on her face the brief second before she backed out told me she got an eyeful. It felt weird knowing my mum had seen my cock and balls, and I couldn't stop thinking about it. The really weird thing is, as the memory repeated in my mind, I started to wonder, "Did she like it?" For some reason, thinking about this excited me. It made me feel weird inside; turned on, even. This soon transitioned to me wanting to see my mum naked. As messed up as it was, the thought of it just got me more excited.

A few days after the initial incident, I couldn't ignore it any longer. Even after making the decision to look at her, it took me a minute to get up. I knew she was in her room, changing from work, so this was my opportunity. As I was about to go, on a whim, I took off all my clothes. She was going to be naked, so I should, too.

As I approached the cracked open door of my mum's room, my heart was pounding like crazy. Finally, I peered inside.

So, to describe my mum. She has the very definition of a mum-bod; thick mid-section with broad hips and a pudgy belly, large, low-hanging breasts with big, red nipples, thick thighs, a wide, juicy arse, and a natural, hairy pussy. When I saw her body for the first time, my dick went from swinging between my legs to sticking straight out, and so fast, I momentarily felt light-headed. Watching her walk around, my hand developed a mind of its own, and found its way around my cock, as I started to imagine my skinny body rubbing against hers. Very quickly, I'd moved on from wanting to see her naked to wanting to feel up her mature, beautiful naked body. It wasn't long after this that my legs also started moving on their own, and I walked in.

It took a moment for my mum to notice me standing there, and her reaction was predictable. "Oh, my God, Phil, what are you doing in here?" She made a token attempt to cover up as she asked me.

"Hm, nice, Mum."

"Very funny, Phil. Now, what do you w-" She stopped when she saw my raging, throbbing boner, which she stared at wide-eyed, before looking at me. "Phillip, what are you doing?" she asked quietly, starting to breathe hard.

"It's okay, Mum." I again slowly stroked my cock as I spoke. "You don't have to pretend..."

"Phillip! Do I really need to remind you I'm your bloody mother?"

"Oh, no, Mum. That's definitely on my mind right now." As we spoke, I couldn't help but notice her discreet glances downward at my member. "C'mon, Mum. We both know you want it..." Saying this, I walked over, and then kissed her. My mum didn't object.

"Oh, God, Phillip," she gasped between kisses. Just as I'd fantasized about, I pressed my body against hers, and I began groping her big, squishy tits. My mum soon reciprocated, and I felt her hand around my dick. "You know how wrong this is..."

"I know, Mum." As our making out intensified, I felt her by now achingly hard nipples poking me in the stomach, and her grip tightening around my cock.

"Oh, darling, let me suck you." My mum then lowered to her knees, kissing down my stomach, until I eventually felt her hot, wet mouth on my cock, and then she began to suck.

"Ohh, fuck, Mum." As the sensation moved into my body, I began to rub my hands between my legs. Looking down, I saw her grip my dick like a vise, while her lips slid in and out, and, with her other hand, she rubbed and squeezed my balls. "Ah, Mum...Suck them..." At this, my mum pushed my dick up, continuing to stroke it, and took one of my balls in her mouth.

After a minute, she rose up on her knees, wrapped her tits around my dick, and rubbed them up and down on it. Instinctually, I started to thrust against her, causing her to moan as I poked the middle of her chest with my swollen head. "Oh, fuck, darling!" she gasped, "I am so fucking wet!"

"Want me to eat you, Mum?"

A moment later, my mum was on the bed, with me on top of her, alternately licking, sucking, and even gently biting both her nipples, while I roughly squeezed her breasts and, with my other hand, was fingering her wet, hairy cunt. "Ohg," she groaned, then gasped, "Oh, God, Phillip," as she began to thrust against my hand.

After another moment, I'd kissed down her pudgy stomach, and had my tongue buried in her drooling snatch. "Oh, God," my mum moaned, trembling slightly, and kneading her breasts, "Oh, God, we shouldn't be doing this," I responded to this by putting my mouth over her cunt, and sucking hard, while my tongue continued to lap up her juices.

"Hey, Mum," I then said, suddenly pulling my face away from her minge, "Lift your legs." She did so, giving me full access to her arsehole, now soaked with her pussy juice. My mum let out a long, throaty groan, as I started eating out her arse.

"Oh, my God. My boy is nasty..."

My cock was throbbing as I rubbed the head up and down my mum's cunt, causing her to shiver slightly, and even jerk her hips. Eventually, I inserted it in her, causing her to tense up, and let out another long groan. "Yyyesss." she moaned breathily, as I started to thrust in and out. "Oh, fuck me, darling." As I did, her hot, wet cunt gripped me tightly.

"Oh, God, Mum...You're so bloody tight..." My mum was starting to noticeably sweat as I thrust into her faster, causing her big tits to sway up and down.

"Oh, God! Oh, God, Phillip! Yes!" As I fucked her harder, my mum's face became more contorted, and her cries got louder and more high-pitched. "Oh, God, fuck me!" Mum started to clutch at herself, and her sweaty tits were rapidly whipping up and down, as my body audibly slapped against hers. Suddenly her whole body tensed up. "Fuck! I'm cumming! Oh, fuck, keep going!"

"Oh, fuck! Mum, lift your legs again!" She did, and, somewhat laboredly, I shoved my cock in her now sweat-dripping arsehole.

"Oh..." My mum let out another throaty groan. "Oh, bloody hell..." By now, she was covered in sweat, her hair matted to her forehead, and her arse gripping my cock even tighter than her twat. "Oh, God, that feels so fucking good." I thrust into her arse faster and harder, until...

"Oh, God, I'm gonna nut!" My mum immediately sat up.

"On your back!" I lay down, and she got on top, and started vigorously sucking my cock, right out of her arsehole. It didn't take long for me to cum, and my mum swallowed all of it, milking my cock for every last drop.

When I eventually stopped, she came up, and we shared a long, tongue-laden kiss, during which I could still taste my cum in her mouth.

"Fuck," she gasped. "That was really wrong, but it felt so fucking good, darling."

"Think we might do it again sometime?"

"Why not? We're already going to hell for that."

"Hey, Mum?"

"Yes?"

"You think Aunt Linda would join us?"

"Possibly? She's always been a bit of a freak." At this, we kissed one more time.
