Down boy

Archy:
Kiss please hon...
Kiss please …
I can feel you want me...
Som:
Gulp Umph… I dunno Arch… Last time we tried you were real sore.
...damn you feel so hot..

Archjy:
whimpers as he feels Soms cock rising between his cheeks lifting his shorts
He writhes in Som’s arms, moaning softly
Mmm, yeah hold me just like that…
He clenches his ass against Som's warm throbbing meat
My body can handle it now… I'm sure..
He stands a little till he feels the tip press against his quivering hole and slowly descends taking the first inch... He feels like a lightning bolt went through him his body throbbing

 Archy cries out in ecstasy as Som’s thick tip finally penetrates his hole, the stretch intense but exhilarating
OH GOD YES STUD! YOU’RE INSIDE ME!
 Som's pre already making Archy's body grow he grabs his ass cheek feeling it fill his hand

As Som’s seed takes root deep within Archy, a slow yet intense transformation begins to unfold. His muscles start to swell and thicken, growing more defined and powerful with each passing moment.

Archy can feel the change happening beneath his skin, his once lean physique gradually morphing into something more rugged and imposing. His biceps bulge as they fill out, his pectorals broadening and becoming rock-hard beneath Som’s exploring hands.

His abs turn into a chiseled eight-pack, every ridge and line standing out in stark relief as they flex at Som's touch. His back muscles broaden and ripple with newfound strength, making him look like a wild predator rather than a domesticated pet.

Even his ass grows larger and rounder, becoming a perfect handful as it clenches around Som’s still buried cock. The transformation is mesmerizing to witness, as if Archy is being remade from the inside out by the potent force of their combined lust.

 A low moan rumbles up from Archy’s throat as he leans in close, hot breath fanning over Som’s face.
