Twilight: Bay City Paranormal Investigations, Book 3

Bo’s pack. They’d stopped using condoms as soon as all the tests came back negative. To Sam’s surprise, Dean had gotten tested as well, and shared his negative results with them both. Just to be on the safe side, he’d said, even though he and Sam had used a condom the one time they’d been together.
With the bottle of liquid lube clutched in one hand, Sam crossed back to Bo and knelt on the floor in front of him. He laid his palms on Bo’s sides, thumbs hooking beneath the elastic of Bo’s underwear. “Lift up. Let me take these off you.”
Bo obediently lifted his hips, allowing Sam to slide the boxer briefs over his buttocks and down his thighs. His cock sprang free, flushed and rigid, hitting his belly with a damp smack. Sam stared at Bo as he pulled the garment down and off. Bo’s braid had begun to come loose, errant strands of silky black clinging to his face and neck. His breath came sharp and quick between parted lips, and his eyes burned.
Sam wanted to kneel at his feet forever and bask in the sight of him, decadent and beautiful in the grip of his need.
A dazed smile spread across Bo’s face. He reached out to touch Sam’s cheek. “Come up here, Sam. Come ride me.”
Rising to his feet, Sam tugged off his hiking shoes and skinned out of his jeans and underwear. He stood astride Bo’s lap and handed Bo the lube. “Get me ready,” he ordered, tugging the rubber band off the end of Bo’s braid. He started unwinding the long, heavy strands, delighting in the satin softness between his fingers.
Bo held Sam’s gaze as he flipped open the lube, coated his fingers and tossed the bottle on the bed. “Take your shirt off too,” he murmured, slipping a single slick digit into Sam’s hole. “I want you naked.”
Sam’s cock twitched and started to fill, making it hard to think, hard to do anything. Thanking his lucky stars he’d worn a sweatshirt instead of something with buttons, Sam tore the shirt over his head and let it fall in an inside-out heap on the floor.
“Mmmm,” Bo purred, inserting a second finger into Sam. “Mine.” He wound his free arm around Sam’s waist and pressed open-mouthed kisses to his bare skin.
“Yours,” Sam gasped, working loose the last twist in Bo’s hair and burying both hands in its dark length. “God. I want your cock in me now.”
“Here it is.” Removing his arm from Sam’s waist, Bo grabbed his own prick and held it upright. “Sit.”
Sam didn’t need any more invitation than that. With Bo’s free hand steadying him, he held his cheeks apart and lowered himself onto Bo’s cock. They both groaned as the wide, smooth head penetrated Sam’s hole. Sam moved as slowly as he could manage, wanting to savor the feel of Bo’s shaft pushing relentlessly into him, filling him up and setting his world on fire.
Finally, Sam’s ass rested in Bo’s lap, with Bo’s prick fully buried inside him. Staring into Bo’s eyes, Sam gave an experimental rock of his hips. Bo’s eyelids fluttered, his breath hitching. “Fuck, Sam. God, tight.”
Sam moved again, trying to keep his full weight off Bo’s injured leg. His thighs burned already with the strain of holding himself in this position, but he would’ve rather died than stop. Having Bo inside him like this felt too good. Besides, it was clear from the fine tremors shaking Bo’s body that he wouldn’t last long.
Panting, Sam rested his forehead against Bo’s and clutched his shoulders. “Okay?”
Bo nodded, one hand curling around Sam’s renewed erection. “Okay.”
Tilting his head, Sam captured Bo’s mouth in a slow, wet kiss. Bo growled. He gave a short, sharp thrust that zinged over Sam’s gland and pulled a kiss-muffled cry from him. Fingers digging into Bo’s skin, Sam began to move in a seesawing figure eight which he knew from experience brought a swift, explosive orgasm every time.
“Oh Christ,” Bo breathed. His thighs spread, hips pulsing up and down to match Sam’s rhythm. “Not gonna last, Sam.”
“Don’t try.” Taking Bo’s lower lip between his teeth, Sam sucked on it for a second, then let it go. “Fuck me. Come inside me.”
“Uh. Yes. Love fucking you.”
Hands clamped hard onto Sam’s hipbones. Bo thrust up into him, the angle sharp and deep enough to hurt. Sam keened, pressed his palms to the wall behind Bo’s head and forced himself down onto Bo’s cock, again and again and again, until his legs shook and sweat dripped from his face and ran in rivulets down
