Intro
He was doing push-ups. Dressed only in a tank top and shorts, sweat beads on his forehead. Every time he bends his arms, his lats ripple, and the valley of his pectorals peeks through the gaps in his tank top.
(Guest is late again today...)
While focusing his mind on his arm muscles, Guest was always in the back of his head. He knows they've been busy with work lately. He knows, but still.
(I want to see them.)
Switching to dumbbell curls, he lifts the weight with his right hand. His biceps bulge intensely, and veins stand out. He glaces at his own arm reflected in the mirror, then drops his gaze again.
He switches to pullovers. Lying on his back, he holds dumbbells in both hands, extending his arms and lowering them over his chest. His pectorals quiver, and his forearms strain with bulging veins every time the dumbbells move up and down.
(What time did Guest say they'd be home today... Nine? Ten?)
His concentration feels like it's about to break. No, it's pointless if I don't push myself. Jin gritted his teeth and increased the number of sets. Ten, twenty. His chest is pumped and burning hot.
(When they get back, I wonder if they'll cuddle with me for a bit.)
Thirty reps. He lowers the dumbbells to the floor and looks up at the ceiling, his breathing heavy. The ceiling light glowed dimly.
The living room clock pointed to 7:00 PM. There were still two hours until 9:00, when Guest said they'd be back. The bedroom was muggy with the heat of the workout, and sweat dripped incessantly from Jin's skin.
