Mick walked into my classroom while I was completing the final exam for my high school senior physics class on my computer.

“Hey, Mick,” I remarked as I paused my typing.

“Hey, Steve, have you seen my wife?” He spoke in a strained tone. “We're suppose to meet in ten minutes.”

As he spoke, I looked down to see Carol swallowing my cum.

“Carol and I are due at The Ratskeller for dinner. If you spot her, let her know to hurry since I'm waiting in my office.”

“Of course, Mick.”

“Just a heads-up before I leave: Carol has been acting strangely recently. I don't know for sure, but I get the impression she's cheating on me.”

“So, you're not one hundred percent sure,” I said, as Carol licked my cock clean.

“No, however, I will eventually find out. It's only a matter of time. There's a good chance I'll hire an investigator.”

“Uh, I'm sorry to hear that,” I said, resisting the urge to cry out in pleasure while she licked my cock as if she were licking a popsicle and then swirling her tongue all around the glans.

It was becoming difficult trying to act normal, so I said, “Mick, I need to finish making this final exam, and if I see Carol, I'll tell her to go to your office.”

“Thanks, buddy. Talk later,” he said.

“No problem, bud, enjoy dinner,” I said with a calm, steady voice, which surprised me since Carol suddenly deep-throated my cock.

“You would not be engaging in sexual relations with me if his cock were as substantial as yours. We have five minutes, so fuck me over the desk,” she said, pushing back the chair I was sitting in.

Carol had unbuttoned her top, revealing two gorgeous, big breasts and deep cleavage. The crimson lace bra secured them firmly in place. I stood behind Carol, lifted her skirt, and saw that she wore no panties.

“Come on, fuck your slut vigorously and swiftly.” She placed her hands on the desk and stated, “Satisfy me completely with your essence.”

With my cock protruding from my trousers and gleaming with her saliva, I drove deep into her pussy. She was tight; those kegel exercises really paid off after the birth of their son six months ago. 

At the time, I was astonished that her husband, my brother, was capable of impregnating her. As a teenager, he experienced a severe accident while riding his bicycle. He fell heavily onto the crossbar, resulting in an injury to his testicles.

Carol approached me as a sexually frustrated woman who had not had an orgasm during intercourse since their wedding night two years prior.

“Ugh, ugh!” she groaned. “Pound my promiscuous cunt with your large, thick cock,” she gasped between heavy breaths.

“The sensation of your cunt is truly remarkable,” I exclaimed as I penetrated her continuously. 

“You are feeling amazing; I am about to experience my first orgasm. Fuck me harder and faster, stud,” Carol moaned between gasps for air.

“You’re on the pill?” Fuck, what was I thinking?

“Yes, right after Tyler was born. Now fill me with your hot cum.”

I took hold of her hips and gave her a fucking that her husband could never give her.

The two of us came simultaneously, the walls of her cunt gripped my pulsating cock as I filled her with my cum. We moaned in unison, “I’m cumming.”

With no time to spare, I stepped back and tucked my cock with our love juices all over the shaft back in my trousers. Carol busied herself, buttoning up her shirt and smoothing out her skirt.

We shared a deep, passionate kiss before she hurried off to meet her husband. We both wanted more, but time was against us, and we couldn't risk fueling Mick's suspicions.

I sat back down, and as I started to finish the physics final, my cell phone rang. A message was received from an unidentified number. I opened it and saw photos of myself and Carol engaged in various sex acts. 

At that moment, Erin—my wife who teaches French—walked in.

The phone fell from my grasp, hitting the floor. She picked it up, looked at the screen, then gave me a mischievous smile.

“So, my beloved husband, what activities have you been involved in? Oh, Carol is having sex with you.”

With wide eyes, mouth agape, I tried to speak, but there were no words,

“No need to speak, you naughty boy. Tsk, tsk. I will tell your brother I have no evidence of Carol cheating. There is one condition, though, I want to join you and my twin sister.”

I sat there stunned for a moment and finally found my voice. “You’re the investigator, Erin?” I said stuttering.

“Indeed, I harbored my doubts, and I hold no resentment towards you. I have a plan. Are you in, or do I show these photos to your brother?”

“I'm in,” I said hesitantly.

“Good, let's go home, and as I ride your cock, I'll tell you my plan.”

~o0o~

As soon as I had locked the door and turned back, Erin was right there, pushing me against the door and pressing her lips against mine. Desire filled the kiss as our tongues intertwined; she tore my shirt open, scattering buttons in all directions.

She nibbled on my lower lip before trailing open-mouthed kisses from my neck down to my chest. While Erin was sucking and licking my nipples, her skilled fingers had unfastened my belt and lowered the zipper.

I gripped her slender shoulders and pushed down, causing her to kneel as her fingers hooked into the waistband of my trousers. With a forceful yank, my erection slapped her cheek as the trousers pooled around my ankles. 

“Mmm, I find pleasure in the moments when you forgo wearing underwear.” Her tone was imbued with profound desire.

Erin gazed into my sky blue eyes, smiled, and seductively traced her tongue over her soft, full lips. At the same time, she tore open her shirt, causing buttons to fly in all directions. Subsequently, she removed her red lace bra and threw it aside.

“Please lie down, my dear, as I must mount my stallion,” she uttered in an alluring tone.

I swiftly removed my trousers, casting them aside. Next, I took off my shoes and pushed them away. I reclined on my back, observing Erin as she positioned herself over my hips and lifted her skirt. Her intimate area glistened with her arousal.

Erin gradually lowered herself onto my erection, stating, “Here’s my plan; I have invited your brother and Carol to brunch tomorrow. All that is required of you is to follow my guidance.”

“Is that all?” I grunted as her cunt enveloped my cock.

“Yes. Oh my, your large cock fills me like no other.” She gasped as her hands settled on my broad, hairless chest.

Erin gently rocked back and forth while I reached out to grasp her hips. Her generous breasts swayed softly as she moved on me. We gazed into each other’s eyes as her pace quickened.

She shifted between rocking and grinding against my member. I was pinching and rolling her nipples with my thumbs and fingers.

Erin accelerated her movements, bringing us closer to the brink of orgasm. I grasped her breasts as her head tilted back, followed by a loud cry.

“Oh baby, fill my pussy, I want to feel your cum splash inside me,” she exclaimed so loudly that I feared the neighbors might have overheard.

“Here, ugh. Here, ugh. Here it comes!” I grunted between labored breaths.

Her cunt gripped my cock tightly as wave after wave of thick cum filled her. Her body quivered each time my balls released their load.

Erin collapsed onto me, our breathing heavy as we slowly regained our composure. We exchanged gentle kisses and soft caresses. Once we had recovered, it was time to take a shower and continue our time in bed. 

~o0o~

The following morning, we were up early and gathered in the kitchen. While I arranged the table and prepared coffee and a pitcher of mimosas, Erin was making a quiche. I helped by frying bacon and sausage links. Additionally, we prepared French toast and a mixed fruit bowl.

The doorbell rang, prompting me to answer it. Upon opening the door, I welcomed my brother and Carol. After shutting the door, I guided them to the kitchen.

“How was dinner?” I inquired cheerfully.

“It was quite excellent,” Mick responded with a grin.

“And what about afterward?” Erin asked playfully.

“You mean the sex? It was mind-blowing,” Carol responded. “What about you, Erin?" Carol continued with a mischievous tone.

“It was the same, mind-blowing,” Erin replied, also with a playful demeanor.

“Shall we, sis?” Carol suggested.

“Yes, let's,” Erin agreed.

Mick and I exchanged glances, both displaying a look of vague uncertainty.

“Boys, we must confess. Carol spent the night with Steve, while I was with Mick,” Erin remarked, giggling alongside Carol. “Come on, guys, what's with the expressions? You both had an amazing time, and we adore you both,” Carol added, still chuckling.

“Ladies, Mick and I thought you agreed to cease this behavior. If you wish to share experiences, at least inform us when you do so,” I stated, with Mick nodding in agreement.

“Where's the excitement in that? Just because we are identical twins, you still cannot distinguish between us,” Carol replied before planting a kiss on Mick's cheek.

“Well, Carol and I will simply continue to switch places until you can tell us apart,” Erin said, kissing me on the cheek.

“Let's have our meal and then enjoy dessert,” Mick suggested, winking at everyone.
