His car was in the driveway next to hers. After parking down the street, I made my way to the backyard and found the back door unlocked. I slipped inside, quietly closing it behind me, and slipped off my shoes. My ears searched for sounds, picking up the muffled voices from the bedroom. I nervously crept to the hallway, peeking around the corner to be sure it was empty, and spotted the partly open bedroom door. Stealthy moves brought me close. I swallowed hard and calmed my nerves, focused on the sounds, and listened to him moaning. I flinched when he spoke.

“Oh, yeah. Suck it, babe… suck it good.”

Slurps and gagging sounds, giggles, and moans followed.

“You suck so fucking good!”

“Ooh, I love your cock.”

She sounded hoarse, a deep and sexy tone in her voice instead of the usual high-pitched chatter. More slurps and glucks, followed by a final loud slurp.

“Fuck me now!” she demanded.

The bed creaked and groaned and they giggled and grunted.

“Oh, yeah, stick it in me.”

“You like this big cock, baby?”

“Oh, yes, give it to me.”

My heart pounded in my chest and it was hard to breathe as I listened to him fuck her. My cock was rock hard as I pictured his big cock driving into her juicy cunt.

“Oh, yes! Fuck me… fuck me!”

“Take it all, you little slut!”

“I am a slut!” she growled. “Fuck me like one!”

“Like this?”

The slapping of balls hitting skin filled the air as she squealed and moaned.

“Yes! Yes! Yes!”

“Take my fucking cock, you little whore!”

A squeal and loud groan pierced my ears as she climaxed, obviously enjoying the battering of his long cock. I knew that sound, the way she moaned when she orgasms from a good fucking, and it made my cock as hard as steel. I wanted to see but couldn’t risk it.

“Turn over!” he instructed.

Creaking and shuffling followed by grunting and moaning. More slapping sounds. I rubbed my shaft through my pants, consciously stopping to avoid blowing my load.

“I love your fucking pussy. This pussy is mine!”

“Oh, yes, baby. It’s all yours.”

The statement stung, hearing her promise it to him.

“You’re my little slut, aren’t you?”

“Yes, baby,” she grunted as the bed creaked. “I’m your little slut.”

A loud gut-wrenching groan erupted.

“Oh fuck! I’m cumming!” he roared.

I held my breath and strained to hear as it was suddenly quiet. Creaking and shuffling around on the bed started again.

“Oh, fuck, babe, that was great…”

“Yes, it was,” she replied. “You better get going.”

I crept down the hallway, hearing a shower start up, pulled on my shoes, and slipped out the door. I quickly returned to my car, my cock still straining in my pants, and waited.

Soon he appeared. I waited until his car turned the corner before returning to the house and entered through the back door again. She was standing at the kitchen counter when I stepped in, a smirk on her face and her hair messed up, wearing the black silk robe I had bought her.

“What was he doing here?” I asked.

“What do you think?” she teased.

“Did you suck his cock?”

She nodded and smiled.

“Did you fuck him?” I asked, already knowing the answer.

“Yes,” she nodded. “He came inside of me, too.”

My cock throbbed intensely. She gestured to me with a crooked finger and I stepped up close to her. She leaned her mouth to my ear.

“I haven’t cleaned up yet,” she whispered. “I knew you would be here.”

I unzipped and yanked my pants down before grabbing her by the ass and lifting her onto the counter. I moved between her legs and pushed my cock into her wet cunt, his cum and her juices making it easier to slip in.

“Oh!”

I pushed in hard, stretching her wide with my thick, swollen pole, and fucked her furiously.

“Whose little slut are you?” I asked hoarsely.

“His,” she panted back. “You like fucking his little slut, don’t you?”

“You know I do,” I growled back with a sly grin.

“Cum in me,” she whispered softly. “Fill me with your cum.”

I groaned and thrust deeply, my cock erupting in huge spurts and pulses of cum poured into her creamy cunt. The orgasm was intense and long, and she squealed in pleasure as my balls emptied into her.

“Ooh, that was a big one,” she purred.

“Fuck, yeah,” I agreed.

She smirked and turned her head to one side, sucking on her lower lip as she looked at me.

“I saw you by the door,” she admitted with a giggle. “You were listening.”

I nodded and slipped myself out, noting the drips falling on the floor, and helped her off the counter.

“It really turned me on,” she cooed as her fingers traced over my lips. “I had such a huge orgasm because of you.”

I chuckled. “Glad I could help.”

“If he knew you were there…”

“It was risky,” I admitted. “But sooo fucking hot. I was so fucking hard listening to you get fucked."

She kissed me and turned towards the hallway.

“Come and shower with me. He has a late meeting so we have all day.”

I followed my friend's wife to the bedroom, my cock hardening as I recalled the sounds I heard earlier, and dropped my clothes on his bedroom floor.
