A few weeks ago I caught my mother having sex with her dog (see part 1 of Mom's Depraved Secrets). Disgusted at first, I later couldn't get the image out of my head: mom on all fours, her nude, yoga-toned body exposed, round ass up in the air, heavy breasts hanging to the floor, dog cock stuck in her pussy. So hot. Later she told me the story of how her dog-fucking adventures began; stemming from a single email from her friend (see part 2 of Mom's Depraved Secrets). She also revealed that she would like for me to see her naked again. My response had been lukewarm and I feared that door was closed; we hadn't spoken since. I decided it was time to get back in touch. I was feeling sexually alive in a way I hadn't felt since first discovering masturbation as a teenager. My curvy, naked, dog-fucking mother was on my mind all the time, non stop. While having sex with with my girlfriend (Laura), I would think of my mom and cum within seconds. My girlfriend was plenty hot, and dripped sexuality, but this new exposure to my mother was overpowering in its effect on me. I was masturbating every day to the mental image of Mom and shooting thick streams of cum every time. My cock even felt bigger somehow. Desperate to see Mom nude again, I called her on the phone. "Hello?" she answered. "Hi mom. It's me." "Hi honey," she paused a beat. "It's been a while." "Yeah," I said. "Sorry about that." "I was starting to wonder when I would hear from you." "Yeah, sorry." I figured I might as well get right to it, it was the elephant in the room. "So, I wanted to talk to you again about ... you know, the thing that happened?" She hesitated, unsure of the direction I was going. "Okay, what about it?" she asked. This was the moment. This was when I voluntarily entered my mom's depraved world and began to uncover all her secrets. "I'd like to discuss the offer you made. It sounds interesting." "Okay, I'd like that," she said. I could hear relief in her voice. We agreed I would drop by the house Saturday morning, and we could chat. Saturday was two days away; it felt like an eternity. 48 hours of imagining various scenarios, wondering how it would play out. Would my own mother really get naked for me? How far was it going to go? I craved seeing her enormous boobs again, I wanted to get a close-up look at her giant brown areolas and nipples. Saturday. I woke up, showered, dressed, and tried to eat breakfast. My stomach was in a knot and I could barely choke down some toast. I was nervous and conflicted. I thought I would feel excited, but the more real it became, the more wrong it seemed. Sons should not be engaging in sexual activity with their mothers. When it was time to leave I had all but convinced myself it was best to cancel, call it off. But my libido got the better of me; I was too intrigued to no-show. I parked in her driveway and knocked on the front door. No answer. Knocked again. Still no answer. Weird. She knew I was coming. I tried the door and it was unlocked. The house sounded quiet. "Hello?" I called out. No response. I walked through the living room and the kitchen. Nobody was around. I headed upstairs, and had a moment of deja vu. This was very much like the day I caught her fucking the dog, and suddenly I knew: she was in her bedroom fucking the dog again, waiting for me to walk in on her. I headed straight to her room and stepped inside. It wasn't quite what I thought. There was no fucking happening (yet). Mom sat on the floor in panties and bra, looking right at me. She smiled when I entered the room. Leon, her yellow lab, sat next to her. She was slowly stroking his erect cock. Oh shit, now what? She continued to watch me as she slid her closed hand up and down the length of his sizable dog meat. Mom looked amazing in her underwear. Her bra lifted those huge tits and made them look even better than usual; the cleavage was a mile long. Her thick legs looked soft, yet toned. "Come here, baby," she said. "I don't think we need to talk about this anymore, I think you should take off some clothes ." This was too fast. I wanted to get a good long look at her naked body first. Kind of ease into this whole thing, but there she was wanking the dog and telling me to undress. "Hold on, mom. Stand up, I want to look at you." "Oh, I can't now. Leon gets upset if I don't finish what I start. Trust me, we don't want him getting angry." She winked at me. "Well, how's this going to work? I came here for you, not Leon." "Why don't you just watch for now, then we'll see what happens." So I watched. I watched her stroke Leon's cock with one hand while she removed her bra and panties with her other hand. When she set her breasts loose it was the most amazing thing I'd ever seen. They were huge, but perfect. At her mature age, somehow still full and firm, with areolas that covered a third of each tit and short fat nipples standing at attention. She saw me staring and smiled. she slid her underwear down her legs and made a point of swinging her ass around toward me and spreading her legs to show me her pussy. It looked great. it was gleaming and wet, the lips puffy and inviting. Then I remembered this was my mom! Jesus, she's acting like a total slut. What kind of woman was she? Did I not know her the way I thought I did? She positioned herself onto all fours and pointed her ass at Leon, who immediately jumped onto her back and started aiming his big dick towards her cunt. He plunged it in with a practiced move and mom gasped a little. Her huge heavy tits hung toward the floor and jumped and jiggled, She pushed her cunt back onto Leon's cock. Hard. He was pumping away. Juices trickled down the inside of Mom's thighs. She rocked back and forth, backing hard into Leon like she couldn't get enough cock into her. Her beautiful breasts swayed in rhythm. God damn, what a hot dirty slut my mom was. My cock was hard as a rock. I was naked too, laying on her bed, getting an elevated view of the action on the floor. Mom moaned and closed her eyes. Lost in the pleasure of the sex. Working hard to try and accept even more dick into her box. Didn't take long for her skin to glisten with sweat; it dripped down all parts of her body. Pussy and dog juice continued to flow down her legs. Drool dripped from her open, moaning, mouth, which she wiped with the back of her hand. She was a hot, wet, slick mess, and the room stank like pussy and sex. It was the dirtiest thing I'd ever experienced. I stroked my dick while watching, and she watched me too. She started cumming hard while staring at my cock. Her body shook, she cried out with gasps, and put her head on the ground, with her round fleshy ass still high in the air getting pumped by thick dog dick. A few more minutes, then Leon hunched on top of Mom and was shooting his load inside her, which triggered another orgasm from her. Mom's skin was shining with sweat, her legs particularly soaked now. I stared at her giant tits and huge areolas, aimed my manhood towards her, and let loose a load of cum that landed on her back, shoulders, and side. She liked that, she rubbed it into her skin, mixing it with all the other bodily fluids covering her. She ran her wet sticky hand through her hair and matted it into a mess. Ten minutes later, Leon came loose from Mom and her pussy poured cum and liquid as if a cork had been pulled. The floor was a mess, I could see why she laid blankets down. Even her tits were dripping sweat onto the floor. Now that she could move around again, she came over and hugged me, rubbing her body all over mine, pressing her ridiculous juggs into my chest and grinding her pussy on my hip. Now I was just as soaked as her. She leaned away and I saw sweat still dripping off her nipples. Except, wait ... that wasn't sweat at all. It was leaking FROM her nipples. It was milk! She saw that I had noticed and lifted a breast and squeezed. A stream of milk shot out of her fat brown nipple. Jesus. no wonder her tits always look so full and firm. They're full of milk. "Do you want to suck them?" she asked. Fuck yes, I did. The areola was so big I couldn't get my mouth around one. I sucked a nipple and got a mouthful of warm milk. The taste was strange and I didn't really want to swallow it so I let it leak out of my mouth, adding to the wet mess of cum and fluids already on our bodies. I looked over and saw Leon licking his cock, a reminder that I had just watched my mom fuck her dog. As I sucked her tits, Mom rubbed my body with her hands. My arms, back, ass, legs, stomach, and finally my cock and balls. When she touched it, it sprang to life, ready for a second round. She grasped it in her fist and stroked slowly. I continued to milk her tits with my mouth, and she repositioned herself and lowered her soaking pussy onto my cock. I slid right in, no problem. I grabbed her ass and held on while she bobbed up and down on my prick. She took a breast in one hand and sprayed milk on both of us. Watching her fondle her breast and ride my cock was too much, I said "Mom ..." in warning that I was going to cum. Which excited her and she bobbed faster, her pussy swallowing my dick with each sloppy stroke. I tensed to start cumming, and she grabbed me in a bear hug. It felt like I shot a gallon of cum into her and I could feel her vaginal walls contracting rhythmically while she had yet another orgasm. She moaned loudly and held me tight. The room was a mess. Cum, sweat, breast milk, bodily fluids everywhere. Our skin was slippery with it. Laying there in the afterglow, my feelings slowly turned from extreme excitement to extreme guilt. What was I doing? That which had been slippery, wet, and hot a minute ago, became slimy and gross. I probably had dog cum all over my skin. Disgusting. I needed a shower. I looked at mom, gently rubbing her skin, spreading the goo all over her body. She was in heaven, luxuriating in it. All of a sudden I didn't feel so great. My mother was a sick woman who fucks dogs, and now I'm an enabler. I really needed a shower. I moved my naked mother off of me, her ridiculously large tits flopping about, stood and headed to the bathroom. After a few minutes in the shower, Mom got in with me. She squeezed shower gel into her hand, and soaped me all over, taking her time with my cock and balls to make sure they were nice and clean. While my mind was still battling guilt and feelings of disgust, I have to admit it felt great to have her rubbing me. Occasionally she would lean or turn in a way that one of her huge boobs would brush or press against me. Her nipples were still leaking milk, dripping at a rapid pace. "What do you do about the milk?", I asked. "I either pump or squeeze. Want to help me squeeze?" After everything else I'd done, why not. I lifted a fat, heavy breast with both hands and squeezed slightly, jets of milk came shooting out in various directions. Over and over I squeezed, shooting more milk every time. Eventually she said it was done and to move on to the other breast. She was clearly enjoying it, she watched me silently with a smile on her lips. "How do you have milk in your breasts?", I asked. "It's a long story. Your dad liked it, so I kept pumping milk daily after you and your sister were born. It became habit, and I like it too, so i kept it up after your father died." When the second breast was empty I returned the favor and soaped my mother's body. rubbing every inch of her curvy hips and ass, oversized tits, smooth legs and body. I payed extra attention to her big areolas and nipples, and her pussy lips. Feeling her all over started to turn me on again, but my cock was not ready for another round and responded pathetically. Mom, however, opened her legs wider and encouraged me to keep rubbing her cunt. I slipped a couple fingers in and found there was plenty of room; added a third. Only a few minutes of pumping her with my fingers and she was cumming again. Her boobs started to leak again too. Those things were uncontrollable! After drying and getting dressed, it was time for me to go. The drive home left me with only my thoughts and feelings. Thoughts of Mom's unbelievable body. Thoughts of all the taboo lines we had crossed. Feelings of guilt and confusion. Feelings of satisfaction and anticipation. Where would all this lead? Would it become a regular occurrence? Was it a one time event? Only time would tell.
