Marathon Mouthwhore by Lila Lucero

Length: 8,900 words

Erika Winchester is a disciplined marathon runner with one shameful secret: an overwhelming oral fixation she can't control. No matter how hard she tries, she needs cock in her mouth and throat to feel truly satisfied.

Her devoted husband, Myron, has tried everything — therapy, toys, endless patience. When he sponsors her full marathon training under the strict, commanding coach Ricky Reynolds, he hopes the intense physical regimen will finally channel her cravings into something healthy.

He's wrong.

As the training sessions grow more hands-on and Ricky's deep voice issues commands that sound more like sexual orders, Erika's addiction spirals. Her mouth waters during every run. Her pussy drips when Coach corrects her form with firm, possessive hands. By race day, she's no longer running for the finish line — she's running straight into total surrender.

When Erika crosses the finish line in triumph, Ricky immediately claims the "real prize" in the private recovery tent. Right in front of her husband, the powerful coach forces his thick cock down Erika's eager throat, turning her post-race cool-down into a raw, sloppy, orgasmic throat-fucking that leaves her shaking and dripping.

What follows is a complete transformation. Myron watches in humiliated arousal as his once-disciplined wife becomes Coach's personal marathon mouthwhore. Weekly training now ends with her on her knees. Every race finishes the same way — gagging, crying, and cumming while Ricky uses her throat like a cum receptacle, and Myron is witness to every degrading, delicious second.

Erika loves her husband. She swears she'll stay faithful. But the only way to keep her addiction from destroying their marriage is to give her mouth to another man… regularly, roughly, and without limits.

Raw. Relentless. Unapologetically filthy.
