Friday morning, I pulled up outside their house at ten sharp, knowing Alan had already left for work. Maureen opened the door in nothing but a silk robe that barely covered her ass. She didn't say a word, just grabbed my hand and led me straight upstairs to the bedroom she shares with her husband.

The moment the door closed behind us she dropped the robe and pushed me onto their bed. Alan's pillow was already under the sheets. She grabbed it and shoved it under her hips, lifting her pussy into the air like an offering.

"Fuck me on his pillow," she said, spreading her legs wide. "Make it smell like your cum."

I stripped fast and climbed between her thighs. My cock was already hard. I rubbed the head up and down her slit, coating myself in her wetness, then pushed inside in one long thrust. Maureen moaned loud, the kind of moan that would have carried through the whole house if Alan had been home.

I started fucking her hard, the bed frame knocking against the wall with every stroke. Alan's pillow bunched under her ass, getting soaked with the juices dripping out of her. Every time my balls slapped against her I thought about how Alan probably rests his head on that same pillow every night, completely unaware it was now a fuck-rag for his wife.

Maureen wrapped her legs around my back and pulled me deeper. "Harder," she gasped. "Make the headboard bang. I want the neighbors to hear what Alan's pillow is being used for."

I gave her everything, pounding her until the wet sounds of my cock slamming into her pussy filled the room. She came first, her whole body shaking, pussy clenching around me. I didn't stop. I kept driving into her until I felt my own orgasm building, then buried myself to the hilt and unloaded. Thick ropes of cum pumped deep inside her, some of it leaking out around my shaft and soaking into Alan's pillow.

We stayed locked together, breathing hard. Maureen reached up and pulled my face down to hers. We kissed slow and deep, tongues sliding against each other while my cock still twitched inside her. My cum was already starting to drip out, running down the crack of her ass onto the pillow.

After a while I pulled out and we both looked at the mess. A big wet spot had formed right in the center of Alan's pillow. Maureen smiled and rubbed her fingers through it, then licked them clean.

"He'll never know," she said, rolling onto her side so we could cuddle. My hand rested on her breast, thumb circling her nipple. She stroked my softening cock lazily while we talked about how Alan had kissed her goodbye that morning without any idea his wife was about to spend the entire day getting fucked in their bed.

We lay there naked for maybe twenty minutes, kissing between sentences, my fingers occasionally dipping between her legs to feel how wet and messy she still was. Eventually Maureen got up and stretched.

"Come on," she said. "Let's walk around the house like this."

We went downstairs completely naked. Maureen made coffee while I stood behind her, my hands on her hips, my cock resting against her ass. We drank it in the living room, Maureen sitting on my lap on Alan's favorite chair. She ground her pussy against my thigh until I was hard again, then led me back upstairs.

This time she wanted it from behind. She got on all fours in the middle of the bed, face down in the sheets, ass up high. Alan's pillow went under her hips again. I knelt behind her and pushed back inside that cum-slick pussy. The squelching sound was even louder now with my previous load still inside her.

I fucked her slow at first, watching my cock disappear between her cheeks, then picked up speed until the slap of skin on skin echoed off the walls. Maureen reached back and spread herself wider for me.

"Tell me how much better you are than Alan," she panted.

"Your husband's pillow is soaked in another man's cum," I told her, thrusting harder. "And you're going to sleep on it tonight with my load still leaking out of you."

She came again, face buried in the sheets, muffled moans filling the room. I kept going, using her orgasm to push myself over the edge. My second load pumped into her even deeper than the first. When I pulled out, cum poured out of her in a thick stream, completely drenching Alan's pillow.

We collapsed sideways and started kissing again. My hand cupped her pussy, feeling the mess I'd made. Maureen reached down and stroked my cock back to life while we made out like teenagers.

"I want to sit on your face," she said after a while.

She straddled my head, lowering her cum-filled pussy onto my mouth. I licked and sucked at her, tasting my own cum mixed with her juices. She rocked her hips, grinding against my tongue while she reached back and stroked my cock. Alan's pillow was now under my head, the wet spot pressed against my hair.

Maureen came on my face, thighs shaking, more of my cum dripping into my mouth. When she climbed off she immediately took my cock between her lips, sucking me hard again.

We fucked in missionary next, her legs over my shoulders, Alan's pillow still under her ass. I pounded her until the bed creaked and the headboard slammed the wall. Maureen was loud, moaning and gasping, telling me how much deeper I went than Alan ever could. I came for the third time, adding another layer of cum to the already soaked pillow.

We took another break, lying naked on top of the covers, kissing and touching. Maureen told me how Alan had folded that same pillowcase that morning, completely unaware it would be used as a cum rag all day. We both laughed, no guilt, just amusement at how thoroughly we were disrespecting him.

Maureen got up and walked to the bathroom. I followed her, watching her ass sway. She bent over the sink and I slid back inside her from behind, fucking her while she watched us in the mirror. My hands gripped her hips, pulling her back onto my cock. We stayed there until I felt another orgasm building, then pulled out and came across her lower back, watching it run down between her cheeks.

Back in the bedroom we tried more positions. Cowgirl with Maureen riding me, her tits bouncing while she ground her clit against my pubic bone. Reverse cowgirl so I could watch my cock disappear into her while she leaned forward and held onto the headboard. Side-by-side with one of her legs hooked over my hip. Every time we changed positions Alan's pillow went with us, getting more and more saturated with cum and pussy juice.

By the fourth round I had her on her back again, legs spread wide, ankles by her ears. I fucked her deep and slow, savoring every wet slide. Maureen reached down and rubbed her clit while I pounded her.

"Fill me one more time," she begged. "Make sure I'm dripping when you leave."

I came hard, my fourth load pumping into her already flooded pussy. When I finally pulled out, cum poured out of her in a steady stream, completely soaking through Alan's pillow and probably the sheets underneath.

We lay there for a long time after that, naked and sweaty, kissing softly. My fingers traced patterns on her stomach while we talked about nothing important. Eventually Maureen got up and walked me to the door, still completely naked, my cum running down her inner thighs.

I left at five, knowing Alan would be home soon. Maureen stood in the doorway waving goodbye, her pussy visibly dripping. I drove away satisfied, thinking about how Alan would climb into that same bed tonight, rest his head on that cum-soaked pillow, and have no idea his wife had spent the entire day getting fucked senseless by another man.

Maureen would probably change the sheets. But she'd leave that pillow exactly where it was, still reeking of sex, still stained with my cum. And Alan would lay his head on it without ever knowing what it had been used for.
