Isaac lets out a low moan as he thrusts into Stiles.

"That's it, baby. You're making Mommy feel so good." Stiles says softly, bringing one hand up to run his fingers through Isaac's hair, pulling him closer for a kiss.

Isaac whimpers into Stiles' plush mouth. He loves this, he loves kissing Stiles, loves the sounds that Stiles lets out. He speeds up his thrusts, fucking into Stiles a little faster than the slow pace they'd originally built.

Stiles moans as Isaac continuously hits his prostate. He gasps as a particularly hard thrust gets Isaac deeper in him. He wraps his legs around Isaac's hips, digging his feet a little into the small of Isaac's back to encourage him to go faster, which he does.

"Baby, you're so good at this, so good at fucking Mommy." Stiles' hips arch up into Isaac's thrusts, which stutter a little hearing Stiles' praise. Isaac whines, burying his face in Stiles' neck, licking and nipping. Stiles pets his hair, running one hand through the blond curls, his other hand rubbing Isaac's back. "You're okay, baby. You're okay, such a good boy for Mommy." Stiles reassures him.

Isaac’s thrusts gradually slow down until they stop completely. He mumbles something in Stiles’ neck that Stiles can’t hear.

”Baby, you got to speak up.” Stiles says.

Isaac whines but lifts his head and speaks loud enough for Stiles to hear, “Mama, c-can you r-ride me?” 

Stiles smiles, “Of course, baby. Lie back, get ready for Mommy.” 

Isaac complies, pulling out of Stiles carefully before eagerly lying back, head cushioned by the pillows at the headboard.

He watches Stiles get into a kneeling position, straightening out his satiny-lace pink babydoll, before straddling Isaac’s hips, knees on the outside of Isaac’s thighs.

He smiles down at Isaac as he grabs his cock, lining it up with his hole before slowly sinking down, breathless little sounds leaving his mouth.

Isaac watches him reverently, moaning too, as Stiles grinds down on his dick.

”Oh, you’re so perfect, Isaac, always filling Mommy perfectly,” Stiles praises. He slowly lifts up, until just the tip of Isaac’s cock is in him, before sinking back down in one smooth move.

Stiles gasps as Isaac’s cock hits his prostate. He swivels his hips a little, the cock inside rubbing continuously against his prostate, sparks of pleasure zinging up his spine.

Isaac lifts his hands to settle them on Stiles’ hips, under the babydoll. He rubs the skin in little circles. He moans as Stiles clenches on his cock.

Looking up at Stiles now, biting his lip as he starts riding Isaac faster, he’s beautiful. Isaac wants to tell him, but his voice doesn’t work aside from moans and whines.

Isaac plants his feet on the bed, pushing Stiles up, getting deeper inside him. Stiles throws his head back with a long moan, meeting Isaac’s upwards thrusts with downwards grinds.

They move together fluidly, gradually getting faster in their ministrations. 

Isaac pushes up, legs a little more straight, wrapping his arms around Stiles’ middle. The change in position means that Isaac is closer to Stiles’ chest.

Isaac pulls the left breast cup of the babydoll aside before latching onto Stiles’ nipple, sucking and licking at it.

Stiles gasps, left hand flying up so he can wrap his fingers in Isaac’s hair, pushing him just a bit more on his nipple until Isaac gets the memo and sucks harder.

There’s really no word for the sounds Stiles is making, something part moan-part whine, but expressed breathlessly.

Stiles’ nipples are really sensitive, sometimes he can cum just from having them played with.

While Isaac is sucking at his nipples—now the right one—Stiles is still bouncing on the dick inside him. 

The mix of sensations are wonderful, and Stiles can feel his orgasm approaching. He can tell Isaac is growing close, too, because his mouth is off Stiles’ nipples, forehead resting on Stiles’s chest.

“Are you gonna cum for Mommy, baby?” Stiles asks as he grinds down and clamps around Isaac’s cock.

Isaac doesn’t respond, he just whines long and loud. Stiles can feel Isaac cumming in his ass, which sets him off and he’s cumming, too, between the press of their bodies.

They stay like that for a while, regaining their breath, coming down from the high of their orgasms.

Stiles is the first to move, going to lift off Isaac to get something to clean them up with, but Isaac whines and wraps his arms tighter around Stiles’ middle, burying his face in his neck.

Stiles huffs, rubbing Isaac’s back, “baby, you have to let me so we can get clean. Would you like a washcloth or a bath?” He asks.

Isaac grumbles but lets Stiles go. “Bath, please,” he murmurs. 

Stiles, now standing at the end of the bed, smiles softly at him and holds out a hand for Isaac to grab, which he does.

“Okay, baby, bath it is.” 

It doesn’t take long for the water to heat up, Isaac pouring in more bubble bath than necessary, Stiles peeling off the babydoll and dropping it in the hamper, before they climb inside the tub, Stiles leaning back against Isaac’s chest.

When they’re having sex, Stiles is the one to take care of Isaac, but after, Isaac always makes sure that Stiles is clean and comfortable.

It’s a balance. They both treasure these moments, the intimacy they share.

Stiles turns his head for a kiss, Isaac’s mouth meeting his, a short, chaste thing, but no less full of love.

”I love you so much,” Stiles whispers against Isaac’s lips, a smile gracing both their features.

“I love you too,” Isaac whispers back, his arms wrapping around Stiles, pulling him close.
