“this playground sure was a good investment, huh?” phoebe asked as she watched her boyfriend through her sunglasses.
she was perched on a lawn chair in a yellow bikini, soaking up some sun while finn played.
finn, her fully grown 26 year old boyfriend, was hanging upside down on the jungle gym they’d recently built in the backyard.
he was wearing nothing but phoebe’s fleetwood mac shirt (the little thief) and the plain white diaper that phoebe had taped him into that morning.
he’d been wearing shorts too, but in typical little-boy fashion, he had kicked them off at some point, and now they were lying abandoned in the grass.
phoebe watched finn with animal interest as he dangled from the playground.
his (her) shirt was falling down with gravity, revealing his strong ab muscles and his little bit of tummy. his skin was smooth and tan and slightly shimmering with sweat.
phoebe bit her lip, watching as his thighs tightened around the monkey bars as he dangled in the air. his diaper crinkled, squishing against his thighs.
even from several feet away, phoebe could see it was soaked, tinged with yellow. he’d need a change soon, but phoebe didn’t want to interrupt his playtime just yet.
“phoebe!!!! look!! i’m upside down!”
“i see that, silly goose!”
finn giggled, squinting at her upside down. “you’re pretty.”
phoebe laughed, then got up from the lawn chair. she tickled finn’s exposed belly, causing him to squeal with laughter and tumble into the grass below.
“pheebs!!!!” he squealed through his laughter, collapsing down on his back and looking up at her. “hmph. you made me fall.”
she straddled him, bare legs swinging around his waist. she pushed him down firmly into the grass and settled until she was sitting on his wet diaper in her bikini.
finn looked like the wind had been knocked out of him. he obediently laid down, hands going to the outside of phoebe’s thighs, feeling her warm, slightly sticky sweaty skin.
his hands gripped a little harder, pressing her weight into his diaper.
she smirked, seeing what he was doing, and gave a rock of her hips into his lap.
the sound that came out of finn’s mouth was unintentional and… adorable.
phoebe’s face lit up with excitement, hearing the sound.
finn only whimpered, his brain starting to go fuzzy. he nodded, hips helplessly bucking up for more friction.
of course, phoebe was a good girlfriend, and had made sure finn was drinking lots of water while they were outside. and now, his pee had soaked the front and the back of his diaper. feeling the warm, wet weight of the padding on his little boy parts was impossibly good.
phoebe bounced up and down several times on finn’s lap.
a desperate sound came from his throat. he watched his beautiful girlfriend rock back and forth, enamored by the contrast of her tiny yellow bikini against his soggy pee-stained padding. her boobs jiggled in the bathing suit with each movement, and finn reached out to touch.
she caught his wrist and shook her head.
instead, phoebe gave a wicked grin, and pressed both of his wrists together above him on the ground. her free hand gently slid up finn’s stomach, then his chest, then slowly closed around his throat.
she gave just the slightest squeeze of pressure around his throat, while simultaneously grinding into his squishy, soggy padding.
the combination of phoebe choking him while rocking her hips suddenly had finn floating. every sense heightened and blurred as he focused on his breathing and the feeling of phoebe all around him.
keeping him steady, grounded, right where he needed to be. and he knew she would make him cum when he was ready. she got to decide when that was.
finn rasped and babbled something.
“hmm?” phoebe asked in a mock-sweet tone.
“please please please, need you so bad phoebe.” finn gasped.
“awww,” phoebe giggled. “is that what you call me when i’m on top of you?”
“much better, silly goose.” phoebe teased.
and there she was, it was still his lovely, wonderful phoebe. still the woman he loved and knew so well. seeing that glimpse of sweetness made finn come undone.
he cried out, helplessly filling his diaper with something that was not pee, while phoebe cooed and talked him through it, hand never leaving his throat.
“ohhhhh, that’s my good boy, cumming in his diaper for mommy, hmm? such a good boy.”
finn whimpered and squealed as his orgasm washed through him. he thought it would never end, the waves of pleasure making his whole body hum.
he collapsed back into the grass, eyes shut, giggling and breathing hard, mind a fuzzy-blank.
he could barely register phoebe’s hands on his diaper, rubbing and grabbing the front to see just how much he had filled it.
“what a cummy little boy… i love you, sweet pea.”
“i love you, mommy.” finn said sleepily, melting into the grass.
