Sharing a bed with my sisters best friend

It was a sultry summer night, and I found myself sharing a queen-sized bed with none other than my sister’s best friend, Megan. The AC was on the fritz, leaving our bodies slick with sweat as we lay on our backs, the cool cotton sheets barely providing any relief. Megan’s arm brushed against mine, sending a jolt of electricity through my body. I could feel my heart racing in my chest as I tried to ignore the growing bulge in my boxers.

Megan was the complete Package – gorgeous red hair, piercing green eyes, and an ass that could make a grown man weep. She had been staying with us for the past week, while her parents were out of town on vacation. My sister, Sarah, had graciously offered to let her stay in her room, while she bunked with me. It was supposed to be innocent, a simple act of hospitality. But as the days went on, I found myself growing more and more attracted to Megan.

Now, as we lay there in the darkness, I could hear her breathing steadily, the rise and fall of her chest barely visible in the moonlight. I squeezed my eyes shut, trying to will away the dirty thoughts that were running through my mind. But it was no use. My hands itched to reach out and touch her, to feel the softness of her skin beneath my fingertips. I could feel my cock throbbing painfully against the waistband of my boxers, a testament to my desire.

Unbeknownst to Megan, I had been crushing on her hard for years. Every time she came over to hang out with Sarah, I found myself staring at her, drinking in every detail of her gorgeous face and figure. I had fantasized about her countless times, imagining what it would be like to run my hands over her body, to feel her naked skin against mine.

But I knew it was wrong. She was my sister’s best friend, and I couldn’t bet her. I had to keep my feelings to myself, no matter how much it killed me inside.

As if sensing my inner turmoil, Megan suddenly rolled over to face me. I froze, my heart hammering in my chest as I felt her breath ghost over my face. “Can’t sleep?” she murmured, her voice low and husky with sleep.

I swallowed hard, my mouth suddenly dry. “N-no,” I stammered, trying to sound normal. “It’s too hot.”

Megan nodded, her hair brushing against my cheek. “I know, right? I feel like I’m melting.” She paused for a moment, then traced her finger along my collarbone. “Do you ever think about me, Jack?” she whispered, her eyes searching mine in the darkness.

I felt like all the air had been sucked out of my lungs. “What do you mean?” I asked, trying to play dumb.

Megan rolled her eyes, a small smile playing on her lips. “Don’t be coy. I know you’ve been checking me out. I’ve seen the way you look at me when you think no one’s watching.”

I felt my face flush with heat, embarrassed that she had noticed. “I-I’m sorry,” I stammered, feeling like an idiot. “I didn’t mean to make you uncomfortable.”

Megan shook her head, her finger still tracing circles on my chest. “You didn’t. I like it, actually. It makes me feel…desired.”

My cock twitched at her admission, growing even harder than before. “You are desired,” I told her, my voice coming out as a low growl. “More than you know.”

Megan bit her lower lip, her eyes darkening with lust. “Prove it,” she challenged, her hand sliding down to rest on my hip.

I didn’t need to be told twice. I lunged forward, capturing her lips in a searing kiss. Megan moaned into my mouth, her fingers tangling in my hair as she pulled me closer. I could feel her breasts pressing against my chest, her nipples hard little peaks even through the fabric of her shirt.

My hands roamed over her body, caressing every inch of skin I could reach. Megan arched into my touch, her hips grinding against mine as she rutted against me like a bitch in heat. I groaned into her mouth, my cock throbbing with need.

Suddenly, Megan broke the kiss and pushed me onto my back. She straddled my hips, her hands working to remove my boxers. I lifted my hips to assist her, my aching cock springing free. Megan licked her lips as she wrapped her hand around my shaft, stroking me slowly.

“Fuck, you’re so big,” she purred, her eyes filled with hunger. “I want this cock inside me.”

I bucked my hips, desperate to feel her heat. “Then take it,” I growled, my fingers digging into her hips.

Megan didn’t need to be told twice. She lifted her hips and positioned herself over my cock, rubbing the head of my cock through her slick folds. I groaned at the sensation, my hands gripping her hips tightly.

Finally, she sank down onto my cock, taking me to the hilt in one smooth motion. We both cried out at the sensation, our bodies fitting together perfectly. Megan began to ride me harder and faster, her tits bouncing with each thrust.

I reached up and pawed at her breasts, squeezing the soft mounds and tweaking her nipples. Megan moaned, her head falling back in pleasure. “Fuck, just like that,” she panted, her hips moving in a frenzy.

I could feel my orgasm building at the base of my spine, my balls drawing up tight against my body. “I’m gonna cum,” I groaned, my fingers digging into the soft flesh of her ass.

Megan nodded, her eyes wild with lust. “Me too. Don’t stop, don’t stop!”

We moved together frantically, our bodies slapping together as we chased our pleasure. I felt Megan’s pussy clench around my cock, her inner walls fluttering as she came undone. The sensation was too much, and I followed her over the edge, my cock pulsing as I spilled my seed deep inside her.

We collapsed together in a sweaty heap, our chests heaving as we tried to catch our breath. Megan lay her head on my chest, her fingers tracing patterns on my skin.

“That was incredible,” she sighed, her voice filled with satisfaction.

I kissed the top of her head, my arms wrapping around her. “It was perfect,” I agreed, my heart feeling full to bursting.

But as we lay there, basking in the afterglow, I couldn’t help but feel a twinge of guilt. What we had done was wrong, and I knew it. Megan was my sister’s best friend, and I had just fucked her senseless.

I knew I would have to come clean with Sarah eventually, but for now, I just wanted to enjoy the moment. I pulled Megan closer, breathing in the scent of her hair as I drifted off to sleep, a smile on my face.
