This middle-aged couple that has been staying at the motel for a few days now. John is attending a conference nearby for his job and his wife Cordelia goes out to see the sites, though she also likes to sit in the lobby and chat with the receptionist and me. She's a brunette in her late forties, a bit of a mom bod, spankable ass, nice big tits that I came on a couple times. Her pussy is a little loose, but still pretty good for a mother of two. Anyways, she calls the front desk and asks me to come to her room if I have the time. It's the slow part of the afternoon, so I go and see what she wants.

It turns out, her 20 year old daughter Bethany and son-in-law Andrew are visiting her. She introduces me, and tells them that I've been taking good care of her. "He's very kind and attentive, and Bethany, you absolutely have to try riding his cock, it's a lot of fun."

Bethany laughs awkwardly, but Andrew, a 24 year old skinny guy, looks irritated. He says, "Please, I'm the only cock she needs."

Cordelia laughs and says, "Oh, to be young. Worried he'll steal her away once she gets a taste of his dick?"

Bethany blushes and pouts. "Mom, don't tease him."

Andrew huffs. "I just don't want to waste her time with a below average experience."

The mother raises an eyebrow and stands up. She strips off her skirt and panties as she approaches her son-in-law. "Care to prove that you're a better lay?"

He licks his lips and says, "Fine!"

She kneels between his knees and unzips his shorts, pulling his dick out and giving it a few kisses and a long lick. Bethany and I watch in bemusement as she straddles his lap and Andrew lines himself up. Cordelia sighs as she impales herself on his length, wiggling slightly as he hilts. "Mmm, not bad. About the same size, if not quite as girthy."

Bethany glances at the crotch of my pants, then goes back to watching her husband fondle her mother's bouncing tits. They find a rhythm, grunting and groaning as Cordelia's ass slaps against his thighs. The older woman gives Andrew a maternal smile as he buries his face between her breasts, hands gripping her hips as he thrusts into her. All too soon, he jolts a few times, moaning as he fills her with his cream. Cordelia frowns at that, climbing off when he stops groping and thrusting her. She gives Bethany a questioning glance. "Is he always like this?"

The daughter blushes and nods. "I don't mind, I usually finish pretty soon after."

Cordelia pulls her daughter into a hug, her son-in-law's cum dripping down her thighs. "Oh honey, get him a gym membership and have him take a stamina course. Your needs are just as valid as his."

Bethany sighs. "I know, it's just, we're so busy, and..."

Her mother shushes her. "It's an important part of your relationship. Make him make time for it. In the meantime, why don't you give Brandon a try? Just to see what you are missing?"

Cordelia pulls away and gestures to me. I helpfully pull down my pants and boxers, showing off the erection I've had for the past fifteen minutes. Bethany bites her lip and says, "Well, it wouldn't hurt to try..."

She pulls off her blouse and unhooks her bra. Her perky tits spill into the open, a perfect handful. I take one into my mouth, sucking and licking at her nipple as I unzip her skirt and pull it down. Bethany hums happily, squeezing her other breast. I wonder if she's like her mother, and gently bite her areola. Bethany gasps, suddenly panting with need. I nibble up the slope of her boob, rubbing her mound, feeling her get wetter and wetter. I slip a finger inside her as I nip at her throat, just hard enough to sting. She shudders, clenching around my digit, whimpering out, "Fuck m-me!"

I turn her around and push her onto her hands and knees on the bed. Kneeling behind her, I push my cock inside her. Bethany moans as her tight pussy wraps greedily around my length. I groan myself, taking a moment to savor hilting inside the young woman. Then I grab her hip and start sawing in and out of her, slapping her round ass. With each strike, Bethany tightens and whimpers. Her pussy is a wet, squelching mess when I switch to spanking her other cheek.

Meanwhile, Cordelia and Andrew are watching. He's getting hard, while Cordelia sits on the other bed and is fingering herself. "Having fun, honey?"

Bethany moans out an "Mhmm!" I reach down wrap a hand around the younger woman's throat. I pull up and back, careful not to choke her too hard as she arches her back, chest thrust out and jiggling as I keep pounding her. Bethany keens out in pleasure, shuddering and writhing as her orgasm takes away her ability to think. I wrap an arm around her waist and grope her tit as I relentlessly plow her spasming hole. Helpless in my arms, she moans, "Oh fuck! Oh fuck oh fuck!"

Her drool drips down her chin and onto my hand holding her by the throat. I feel myself getting close to my own release, and start thrusting even faster. Bethany whines, reaching down to rub her clit as her second orgasm begins to crest. I let out a gutteral groan as I start cumming, unable to resist the milking motions of her inner walls any longer. White hot pleasure courses through my cock and pools inside her womb. We slowly come to a stop, and I let her down to the bed gently. I pull out and stand on unsteady legs. Looking around, I see Andrew jerking off, while Cordelia is laying back on the bed, idly rubbing her mound with a contented smile on her face. "Good, wasn't it?"

Bethany groans unintelligibly into the blanket, but makes a thumbs up gesture. I smile. Then my phone vibrates, and I fish it out of my discarded pants. There was a guest who wanted to talk to the manager, so I sigh, towel off, then get dressed. Andrew sits by Bethany and tucks her hair behind her ear as she turns her head to face him. "I didn't know you liked to be spanked."

As I leave, she says, "I didn't know either. Maybe next time..."

And that's how I accidentally became a couple's sexual counselor.
