The first thing I saw was a huge cock piston upwards into my stepdaughter. Her pelvis was clean. With her toned body, she had those defined adductor muscles that jut out from her pelvis towards her knees. The high school senior had distinctive lines from her pelvis to her rib cage. As she rode her man, I watched closely as her muscles shifted with each thrust of the cock. Her breasts were firm, round, and a size that was just perfect. Her collarbones were sharp as she had her shoulders elevated, arms extended, and holding against the guy’s chest. Her mouth gaped open, moaning in pleasure. She had blond hair, and her eyes were icy blue. And they were staring right at me.

Oh, fuck.

I was getting a glass of water for my girlfriend when I heard noises upstairs. I thought my stepdaughter was in pain. That was the excuse I told myself. Just before I was about to fling the door open, I heard there was another person in the room. I wasn’t thinking when I twisted the handle and opened the door.

Even as our eyes locked, Morgan continued to fuck the man below her. Luckily, her incredible body blocked his view, and he was oblivious to my presence. My eyes wandered to Morgan’s body. The cheerleader had a decent tan to pair with her rock-hard body. When I looked at her eyes again, she smiled and winked at me. I took a step back and started slowly closing the door.

“No!” she moaned. “Please stay. Don’t stop watch—I mean—fucking me! I’m close!”

But he was closer. He groaned and grunted, then twitched.

“No!” Morgan shouted desperately. Her movements forced his cock to plop out. Not wanting to ruin his own orgasm, he ripped off the rubber, jerked himself off, and came all over Morgan’s amazing midsection. I watched closely as the semen melded with her sweat. Morgan sighed and looked disappointed.

“What took you so long?” Lauren asked as I crawled back into bed. She had her back towards me and was facing away.

“Nothing. Just heard noises. From outside,” I lied.

She reached back to touch me. She noticed my hard-on. “I’d take care of this if I didn’t have an early flight.”

“That’s okay, honey,” I said.

“Feel free to relieve yourself tomorrow,” she said, smiling, then went back to sleep.

I was definitely not the popular kid growing up, and I never had a chance with a cheerleader. I mean, with a name like Peter Dinger, you’re bound to get made fun of. I didn’t lose my virginity until I was in my thirties, and I had a few failed relationships. Then I met Lauren. I was fifty years old, and Lauren was forty-one. She’s absolutely beautiful, but while I’m here confessing things, I’ll admit that I wish I could have had her when we were younger. Seeing Morgan fuck did not help those thoughts. She looked just like Lauren. Maybe even hotter.

While Lauren and I weren’t married by law, it felt that way. Especially after we bought a house and moved in together. Lauren worked in international sales and traveled often. Her current assignment was taking her to Japan, and she left Saturday morning to help herself get acclimated sooner.

I was having a late morning and drinking coffee when Morgan returned from her jog. She was wearing those shorts that didn’t even cover her ass cheeks and a sports bra that went maybe two inches below her breasts.

I was awkward around her, but she seemed confident around me. She smiled and hugged me. She never did that. Then I felt her hands against my chest.

“How’s your morning, Morgan?” I asked awkwardly.

She sighed, “Mostly good. But you know. Didn’t get off last night. So that’s still on my mind.”

I nearly choked on my own spit. Then I said dryly, “I’m glad you used protection. But you have to be careful when they…” I paused to think of a more proper term. “When they ejaculate on you like that. It can slip down.”

“I’m on the pill,” she said quickly. “But some girls lie, and the boys rubber up anyway. Smart, though it would be nice if they could last.”

“That comes with age and experience,” I said.

Her face was so close to mine. Her breath was practically touching my lips. “That’s true. I’ve noticed that. Do you have a lot of experience?”

“I actually don’t,” I admitted. “I wasn’t popular in high school. Or college. Or at work. Wait, what do you mean you noticed that.”

She laughed, then she sighed weirdly, almost like a pleasurable moan. “I may have fucked a teacher. Or three. And a principal.”

My jaw dropped. Her principal was older than me. Morgan smiled at me. Not a normal smile. But a wanting smile and then a wink. She stepped back and removed her top. That’s all that I needed to lose control. I stepped forward and grabbed her breasts. She moaned as I squeezed them. Then I turned her around and pulled down her shorts. I pushed her against the kitchen counter. The blinds to the window facing the street were hoisted, but I didn’t care. I lined up my cock to her entrance.

My conscience returned, and I pulled back. “Morgan, wait. We can’t—”

She was quickly on her knees. Holy shit, she moved so fast. I felt the warmth of the inner lining of her mouth as she took me inside. I felt her suck me hard, and fuck. Her lips on my cock made smacking and slobbering noises that caressed my senses. I loved the feeling of her tongue swirling around my dick while she sucked.

“No, stop!” I commanded. She stood up and leaned against the counter. “We can’t do this. You’re my stepdaughter.”

“Not officially,” she corrected. “Not yet. Can you at least get me off?”

The defensive walls were very thin. My body was waiting for every damn excuse. I’m not a strong person, but Morgan was only a few inches above five feet tall and weighed a little more than a hundred pounds. I lifted her to the counter, spread her legs, and dove in. I lapped her and fucked her with my tongue, then I stuck two fingers in as I sucked on her clit.

She moaned for me, “Mmm… fuck! Yes, Pete. Don’t stop. I fucking love that. Ah!”

Lauren was always patient with me and gave me instructions. I’ve never been so vulnerable with a woman. I felt guilty for using her lessons on her daughter. But I couldn’t stop. I had to make this young woman cum. I tried everything. I rubbed on her clit, licked it, fucked her with my fingers.

“I’m… fuck… Pete. I’m going to… FUCK! Aaaahhh!” She screamed for me. Her body shook. Her head bumped the window behind her, but thankfully not too hard. One hand braced the counter, and another held the cabinet near her head. And she fucking screamed. “Oh, my FUCKing god!”

I loved the way her body shook as her orgasm cascaded. She combed my hair with her hands. I stepped back after her shivering stopped. I still couldn't believe it. But she didn’t take her eyes off me.

“Are you sure you don’t want to fuck me?” she said with a mischievous smile. She got off the counter. She briefly looked out the window to see two shocked neighbors walking past. Thankfully, they couldn’t see me. The woman slapped her husband on the arm, and they continued.

“We can’t,” I said. “We already did too much. Fuck.”

“Okay,” Morgan said. “This is finally your chance to fuck that young hot girl you always wanted. But if you want that chance to walk away, then that’s your choice.” Then she strutted towards the living room. She didn’t even take her clothes with her. Fuck! That ass. Oh, my god. That ass. The way her ass bounced with each step...

“Fuck!” I shouted as I gave in. I walked towards her and pushed her against the back of the couch. This time, I didn’t hesitate.

“Oh, fuck!” she moaned.

Her cunt was tight. Gripping me but still wet and slippery. She felt warm as I pushed in and pulled out. “God fucking dammit! Fuck! Oh, my god. Your pussy feels so fucking good!”

“Yeah? You feel so good inside of me, Pete. Keep fucking me like that. Yes! Just like that. Fuck your stepdaughter.”

A shiver of guilt came over me. I fucked her, then I remembered my girlfriend. I pulled out, then I pounded back in, and I remembered meeting Morgan two years ago. I remembered her biting her lip when she smiled at me. Wait. Fuck. Was she thinking about this for a while?

I was rabid. I lost control. I fucked her hard and fast.

“Oh, yes!” she cried out. “That feels so fucking good. Don’t stop fucking me, Pete. Don’t stop FUCKing ME! Oh, god, yes! Fuck, Pete! Fuck me! Oh, shit! I’m close again! Pete, I’m… FUCK!”

Holy fuck! When I got Lauren to cum, I loved the way her pussy squeezed on my cock. But this was different. Morgan was so tight when she came. It was addicting. Even as I was fucking her, I was already dreaming about next time. Next time!? What the fuck was I thinking? This can’t happen again.

I never felt a woman grab my cock that hard with her hand. I couldn’t believe it was Morgan’s orgasmic cunt. She shook again as she came. “Morgan… I’m close, too.”

“Not yet, Daddy!” she commanded. “Let me… finish… then I’ll take care of you. Oh… fuck. Fuck! God! Motherfucking…”

“Morgan! I can’t hold it! I’m going to… FUCK!”

With her ass, she pushed me back. She twisted quickly and was on her knees. The first spurt of my orgasm was already exiting the tip of my cock, slamming on her breasts and face. Then she took me in. Holy fuck. Does a mouth feel good when you’re cumming.

I groaned uncontrollably as she sucked on my cock, beckoning more waves of semen into her waiting mouth. She squealed even as she worked my cock. I could tell she was still cumming herself. She milked me, and I creamed her tongue. I looked down at her piercing blue eyes. She was so fucking cute with that blond ponytail of hers. I witnessed dimples form on her cheeks as she sucked me with ferocity while she was still squealing. Then she cracked open her mouth, showing off that creamed tongue. Cum spat out as she wailed in pleasure. I had so much built up from last night that I came so much. The pile of cum on her tongue eventually collapsed and spilled down her lips. It was so fucking hot.

She was still cleaning up her mess when I said, “We can’t do this again. I love your mother.”

I stepped back. She leaned against the back of the couch. Holy fuck was she hot. “One day,” she said. “Just give us this one day.”

“Morgan, we can’t.”

I would occasionally need a pill to stay hard. It was more of a confidence thing. Yet, staring at Morgan’s body, I was still rock hard. She stepped forward and turned, back against my chest. She rubbed her ass on my dick, then grabbed it with her hand. She led me to the other side of the couch. I fell onto it, then she slowly climbed and straddled me. She lowered herself on my still stiff cock.

I moaned, but then I gathered my senses and said with a straight face, “Just one day. Then we go back to the way it was.”

She smiled, “So, the way it was? Not fucking each other, but constantly wanting to fuck?”

She was right.

I stared at her incredible body as she lifted and then descended slowly.

I grunted at each drop but managed to repeat, “Just one day.”

It was a lie.
