My name is Mi, which stands for Mia. I live with my stepson Matt, daughter Leah, and husband Anthony. Anthony and I got married a year ago.

Matt has always been a pervert; he enters my room, stands behind the curtain, rubs his cock while I take a naked shower, and observes me as I change.

However, I always overlook it since he's a curious teenager and not causing any harm; he's merely looking and perhaps fantasizing about me while masturbating in his room.

However, over the past few months, I've been feeling something: I get excited when he looks at me while I'm naked and touches himself. At times, I also caress myself while imagining him. I realize it’s not right, but I couldn’t help myself.

While I struggled with all these emotions, this happened and transformed our relationship for good.

When Anthony was away for a business meeting one evening, after taking a shower, Matt, of course, watched me and stroked his cock. I went downstairs in my bathrobe to have supper with the kids.

After supper, we decided to watch a movie together. I enjoyed some wine while we settled in with popcorn on the table. Leah fell asleep as she watched.

As I finished the glass of wine, I tried to place it on the table without noticing that my bathrobe was in a state of disarray, exposing my butt without a panty. Matt was whispering to himself, and I could hear it: "Holy shit! Under her bathrobe, she's completely nude! Her leg keeps rubbing against mine, too! It appears she wants me to see it!"

Maybe it was the liquor, or maybe it was me, but I heard him and did nothing. I'm not sure.

Leah rested her head on my shoulder while I sat back on the couch and began to softly brush her hair. I pretended to be asleep, closing my eyes.

Unbeknownst to me, while I put my glass down, my robe loosened further as I bent over, revealing my breasts as I sat back down.

"Screw it! Take a look! Her breasts are clearly visible," Matt whispered.

As soon as I heard this, my heart raced with the excitement of sitting next to Matt and being nearly nude.

As I was leaning against Leah, Matt secretly leaned back to have a better look at my butt, which was still nude and pointing in his direction.

"Have a look at her ass! Is she trying to kill me? Pointing it that way at me," he said.

He couldn't resist stroking his enormous erection through his shorts while he was staring at my ass. His cock was hardening like a rock as he saw his stepmother's obscene sensuality.

"Fuck! I'm so hard that my cock will rip through my shorts," he said.

He saw that Leah and I had both dozed off in front of the movie as he raised his head to make sure we weren't looking at him.

"Damn! Maybe it's my chance to rub one out finally. With her changing earlier, the shower, and now with her ass under my nose, I feel like I've been hard for hours," he said.

As soon as I heard Matt was thinking about rubbing his cock on my body, my excitement grew.

He took his cock out and began to masturbate discreetly, slowly caressing his dick while continuing to gaze at my pussy, which was faintly lit by the TV.

"Holy shit! I'm really hard! This is so thrilling! But damn, I want to touch her. While she sleeps, I might do it for a short while," he said.

But as he tortured himself over whether or not to touch me, I opened my eyes and saw Leah's face, which snapped me out of it. I mentally screamed, "OH MY GOD! What is Matt doing? What am I doing, too? This is not what we should be doing. What should I do? This is so embarrassing, but I don't want to create drama or humiliate him in front of Leah. That would be too hurtful. I should pretend to be asleep till he's done."

I tried to maintain my composure while Matt was doing his business by closing my eyes once more, but as soon as I did, I was stunned to feel his hand on my ass.

"Oh god! What is he doing!?" I said.

Maintaining composure, I was immobilized, trying to think of what to do while Matt continued to caress my ass.

"Screw it! It's amazing how silky and perfect her ass is," he said.

"God! What should I do? What should I do? He keeps caressing my butt," I screamed mentally.

"Shit! I can even feel her asshole, and her ass is the best. Perhaps I might try tickling it since she doesn't seem to notice," he said.

I could feel my asshole twitching as he touched it, and I knew he was going to poke his finger in it!

He bravely pressed forward and inserted his thumb into my ass, testing the resistance while I continued to play the sleeping card.

"God! This is completely wrong. Although you must let him do so, Mia, you can't let him be traumatized in front of Leah," I said.

"Wow! Even though her ass is tight, it swallowed my thumb right in," he exclaimed.

I could tell he was going to cum because of the way his breathing quickened, and so did his fingering and his jerking off.

"Fuck! I'm going to cum; let's do it on her ass, or maybe I can just put the tip in…" he said.

I had to stop him as soon as I heard this because I knew it was getting out of hand.

Suddenly jumping forward on the couch, I faked waking up in a panic, surprising the still half-asleep Leah and Matt, who barely had the time to hide his erect dick.

When I screamed, Leah leaped to her feet and shouted, "What? Mom, what happened?"

I shrugged off the awkwardness and replied, "Nothing, sweetie. I just fell asleep and had a dream. Perhaps we ought to reschedule the film for another time."

"Sure! I kind of fell asleep there, too." She said.

Hiding his erection, Matt said, "Yeah… Yeah, I am also feeling sleepy." As if nothing happened on the couch.

"I'll clean up; you two go to bed," I said.

They both went to their room upstairs.

I was getting over the idea that Matt nearly fucked me there, and I nearly let him, feeling both embarrassed and a little excited. I followed them upstairs after cleaning the TV room.

I could hear the front door downstairs opening as I made my way down the hallway to my room.

I'll wait for Anthony in bed, as I figured it would be him. However, before I went to bed, I realized I needed to start the washing machine cycle.

However, I was shocked to see Matt jerking off and smelling my panties as I opened the laundry room door.

I had no time to think about it since I could hear Anthony calling me as he approached. "Babe! Where are you?"

I was terrified of what he would do to him if he ever discovered Matt in that state with my underwear.

Fearing that Matt and I would be caught in this scenario, I hurried inside and quickly locked the door behind me.

"God! Just let Anthony pass, please." I prayed.

Matt approached me curiously to find out what was going on, surprised that I hadn't yelled at him.

"Honey? Are you here?" Anthony asked.

I abruptly turned around, keeping the door closed and responding fast to prevent Anthony from attempting to open it. "Yes, Hun! I'm here, just finishing some washing before bed."

With his dick in hand, Matt began to masturbate once more, whispering, "Sorry Mi, but I can't take it anymore," as he was overcome with excitement and pent-up emotions.

"What!?" I whispered.

Panicked by the thought of both of us being found, I tried to stop Matt by lowering the level of my voice.

"What's going on?" Anthony enquired.

"Nothing! I'm sorry; I accidentally got some detergent on me, Hun." I answered.

I was trying to remain calm and keep Anthony from entering. Matt, meanwhile, continued to jerk off, looking at my butt.

He took advantage of the situation since he wanted to play with my ass so badly.

While he was still masturbating, Matt suddenly walked over and raised the bottom of my bathrobe, exposing my ass.

"Holy shit! Your ass is so fucking hot," he said.

When I tried to stop him, I was able to control myself and speak quietly despite my shock and surprise.

"Hey, Matt! What are you doing? God! Are you insane? If you continue in this manner, we will get caught." I said.

However, Anthony continued talking as I was attempting to stop Matt, so I had to maintain my composure and handle the matter at the door rather than with his filthy son.

"Today was a miserable day for me! Because of the nonsense the other day, I had to defend myself again," he said.

"Hun, I'm sorry!" I replied.

Meanwhile, leaving my robe up and stuck in the belt, Matt pushed his luck further, gripping firmly one of my ass cheeks and started to knead it.

"Shit! You're completely letting me do whatever I want. Tell me you want it as much as I do," he said.

I could not speak because Anthony was standing directly outside. I slapped his hand away to keep Matt at a distance and to maintain my composure without being caught, with me half-naked and this horny teenager holding his cock.

"Stop it!" I whispered.

However, Matt continued to grope my butt while I was gently begging him to stop, trying to remain composed and discreet, and pulling his hand away. He was still excited and thrilled by the scenario, mistaking my tone for playfulness.

"Aha! You're playing hard to get, and it looks like you are trying to catch my cock," he said.

Unaware of what was happening inside, Anthony kept talking on the other side of the door.

"Well, be quick! Because I'm going to need a drink!" Anthony said.

"Yes... Yes, hun!" I answered while I kept pushing Matt away from my butt, and eventually, while shielding my butt from his hand, my hand froze as I accidentally touched his dick.

"Oh my god! Is that your...!?" I said.

"Wow! You got my cock in your hand; I knew you were trying to catch it!" Matt said.

"When you're finished, please bring me a drink," Anthony asked, and finally, I heard Anthony heading to our bedroom, immediately removing my hand from Matt's dick and turning around. I was pleased that we were not caught, but I was also disgusted with Matt for his actions.

"What's wrong with you?" I shouted.

"Sorry!" Matt replied.

"Young man, that's not enough," I said.

"I know, it's just... Look," he released his dick and showed it to me. I looked down to see it pulsing as hard as a rock and bouncing back up.

"My dick has been hard ever since I saw you in your room, naked," he said.

I pretended not to understand what he was saying and said, "What? You've seen me naked. Where, when, and—above all—why? Were you spying on me?"

"Come on, Mi! You know I watch you taking a naked shower, and you enjoy it as well, which is why you have never mentioned it to anybody or attempted to stop me. Come on! Admit it," he said.

Matt's directness shocked me, and I stammered, "I...I... I don't know what you are talking about."

"Come on, Mi! You know what I'm talking about, and I also know that you were awake on the couch during the movie. I felt your asshole twitching when I inserted my thumb in it; you liked it, didn't you?" he said.

I was getting thrilled by Matt's words, and I could feel my body burning as I stared at his rock-hard cock. My eyes fixed on it, and I was getting horny. My anger was changing into lust.

"I... I don't know, Matt." I said.

"Just confess it now; your nipples are growing hard, and you couldn't take your eyes off my cock. Accept that you want to fuck me," he said.

I shouted, "Alright! I have been thinking... thinking about us. But since you're my son, we can't do it, Matt."

"STEPSON! I am your stepson, Mi. Come on! It could be our little secret," he said.

I replied, "All right! But... But no one can know about this, and it's going to be this one time only."

Matt was first taken aback by my response, but he immediately grabbed the ball and ran with it.

"You little slut, you have no idea how difficult it has been for me to watch you naked every day and do nothing about it. Tonight, whore, I'm going to fuck you like the devil," he said.

I'm usually in charge of these kinds of situations, but as I listened to Matt curse me, I wanted to be dominated by him. I simply took the sub's place.

"I know, I'm sorry, honey! What do you want me to do?" I said.

"To begin, you can remove your robe and lean against the door. Seeing your ass will be sexier without it," he said.

Setting the bathrobe aside, I spun around as Matt asked, pointing my ass in his direction while thinking, "Oh my god! I feel so exposed right now, and my stepson is going to fuck me."

"Whoa! That's fantastic, Mi! You have a talent for flaunting your ass! It's so damn hot; look at that!" he exclaimed.

As he got closer, Matt firmly grasped one of my ass cheeks and slapped it passionately while using his other hand to masturbate once more.

I moaned softly, "Aaah! Matt!" as he slapped my ass.

"Exactly! Say my name. Fuck! It's amazing how firm and squishy your ass is all at once!" he said.

As he continued to knead my butt and masturbate, I noticed his fingers lingering closer and closer to my pussy and asshole, teasing them as he tested their opening.

I said, "My goodness! Just give it to me, Matt, and stop teasing me like this. Ahh!"

He inserted the tips of his fingers into both of my openings before I could finish speaking, sending shivers down my spine.

Matt pushed his fingers farther and moved them quickly inside each of my openings.

"What are you... Aaah! Matt!" I said as I moaned with pleasure.

"I don't want to get caught, so keep your voice down, slut," he said.

"Aaah! I'm sorry! Don't stop, please!" I begged him.

"You're sorry!?" he asked.

I answered, "Mmmmh! Yes! I'm sorry!"

"Then you'll stop talking and accept your punishment!" he said.

While I groaned in delight at the attack of his fingers, Matt continued to speed up his fingering and masturbate while pressing the tip of his cock against my butt.

"God!! It feels so good! You're going to make me cum! Aaah! Mmmmh!" I said.

"Wow! You truly love being pushed around. You're loving it, aren't you? Do you love it getting double-fingered hard?" he asked.

I answered, "Mmmh! GOD! YES! Aaah! I LOVE IT!"

"Do they feel better than Dad's?" he asked.

"Mmmh! YES, YES!!! OH GOD YES!!!" I shouted as I reached my climax.

After Matt used his fingers to make me cum, I lost the strength to stand and collapsed to my knees.

"Holy shit! You really felt it! Now it's my chance," he said.

I was taken aback when Matt suddenly grabbed me by the hair and twisted my head to face him.

"Ahh! Come on over, Mi! I'm going to cum as well," he said while grunting, and I watched loads of cum rain down on my face.

"Ahh! Shit! Take that!" he said as he came all over my face.

My head spun as Matt's cum continued to pour in, covering my face with a thick, warm layer of cum while its strong smell overwhelmed my senses.

I was stunned and distractedly gazed at Matt's cock, which was still huge, firm, and dripping with sperm. The intensity of the moment and the strong scent of his semen overwhelmed my senses and thoughts.

"Damn it! You look so gorgeous with my cum all over your face," he said.

As I struggled to focus, Matt exclaimed, "Hey Mi! We can probably play another round!"

Brought back to reality by his words, I said, "What!? But? You... You already just came."

He said, "Look, I'm so hard! I'm afraid it won't go down since you're so fucking hot with my cum all over your face. I can also tell you want it too by the look in your eyes."

I replied, "Ahh, I... I want it, but your dad is waiting for me; I don't think we have time."

"We've been in here for a long time, and Dad hasn't called you, so I guess he's already asleep," he said.

I opened the laundry room door and looked into my bedroom; I noticed Anthony was asleep.

"You're right, he's asleep," I said.

"So, what do you think? We go to my room!?" he said.

We then went to his room, across the corridor, naked and my face still dripping with Matt's cum. And the thought of walking into my house, naked and covered in my stepson's cum, made me even more excited.

The moment we entered his room, he said, "Come on, now sit on your knees and show me your boobs; I want to fuck those big jugs."

I obeyed his order and knelt, my face still glazed with his cum. I positioned myself for him as he requested, hands on my back, exposing my breasts while he masturbated.

"Is this ok, baby?" I asked.

He answered, "Fuck yeah! You're the best slut! Your tits are so fucking hot too!"

"Oh my god!" I thought to myself. "It's so thrilling; I never imagined that I would enjoy being enslaved in this way."

As he approached, Matt casually grabbed my breast and began kneading it while masturbating by rubbing his cock against it.

"Whoa! Your tits are so lovely! You know what? I feel like fucking these tits right now," he said.

I nodded in agreement, and he said, "Open your mouth and stick your tongue out."

After I followed his orders, he put his fingers in my mouth and down my throat. I coughed and gagged as he fucked my throat with his fingers, but he wouldn't let me go until my mouth was full...
