Summary
Something in Ryland wants. It’s an aching, hungry type of desire that seems to form a black hole in his stomach. He’s lightheaded, swapping spit with his brother, and he just… needs. Now.
Ryland fumbles for Colt’s belt, fingers eager and shaking.
He gets as far as tugging the buckle loose before Colt’s pulling back with a gasp. A line of spit connects their lips, broken with a swipe of his tongue. Ryland twitches, stomach squirming.
“What—” Colt’s hand flies to Ryland’s, stilling their trembling. “Ry, Ryland, what are you doing?”
Ryland tries not to whine at the interruption. He feels desperate, in a way he rarely ever does. “I wanna…” He swallows, shudders. Finally finds a name for that aching desire. “Wanna suck you off.”
—
Ryland discovers just how much he likes having Colt in his mouth.

Summary
As Colt Seavers is driving to Tom Ryder's loft, he nearly hits someone on the way there. When he finally sees who he nearly hit, his world will never be the same.
Because the man he nearly hit looks exactly like him. A carbon copy, if you will.
And what does this carbon copy of Colt Seavers do when he sees him? He runs.
And maybe Colt Seavers will regret chasing his doppelganger down when a 400-pound rock spider comes to his doppelganger's rescue.
(A story where Grace and Rocky have accidentally shucked themselves into Colt Seaver's world during the movie and get unwillingly tangled within its plot.) (Alternating POVs between Colt and Grace)
(Illustrations included!)
