Bruce panted as he ran into the woods away from Clark, doing his best to cover his scent and heat signature by covering himself in foliage and dirt. He knew that he wouldn’t get any egregious injuries, but he still didn’t want to get caught, considering who was the predator and who was the prey.
Bruce always knew that Clark had some feelings for him, as he always treated Bruce with respect and content. Things evolved into a romantic friendship over time, and soon, a full blown sexual relationship. That didn’t mean that everything was perfect. Clark, for as kind and sweet as he was, harbored some feelings of possessiveness over Bruce. He didn’t like other members of the Justice League touching Bruce, even if Bruce himself could handle himself through intimidation. Clark was always gentle too - most people would love that, but Bruce wanted Clark to let go just a little bit and treat him roughly. Bruce wasn’t used to all the gentleness that Clark gave, and would like him to express his powers a little bit - the batsuit would handle most of his strength and Bruce would likely walk away with a slight limp.
Bruce was the one who proposed that they try primal play after Hal Jordan got a little too close to Bruce, causing Clark to nearly expose their secret relationship. The rules were simple: Clark could not listen for Bruce’s heartbeat, he could only use limited x-ray and heat-seeking vision, he could not use superspeed or super strength, and Bruce would do everything to evade him for several hours without use of his gadgets. If Bruce got caught, Clark could fuck him however he wished and he could be rough. Most people wouldn’t see this as high stakes, as primal play was usually done in a safe location. However, Clark suggested that they go somewhere isolated so that if he did end up using his powers, no one else would see and no one would get hurt.
Bruce had an hour head start and Clark would get two hours to search for him. He was taking this extremely seriously, even if Clark was his boyfriend and he trusted the man not to leave lasting marks on him. Bruce never half-assed their sexual play, and he wasn’t planning to start now. He did his best to lower his heat signature as much as he could by rubbing the surrounding dirt on him - it would mess with Clark’s perception when he tried to use his heat-seeking beam. After finding a tree with a deep indent in the trunk, Bruce settled in, making sure as little of his body stuck out as possible from the tree trunk. If Clark couldn’t tell that the tree was hiding Bruce’s skeleton with his x-ray vision, there was a chance he could win.
Bruce slowed his breathing and closed his eyes. Clark was allowed to search for him now, and Bruce was sure that he was beyond pent up. Clark hid his urges well, trying to be a gentleman for him, but Bruce knew that by allowing Clark to let loose, he could be hurt mildly and end up not being able to walk well from how hard he could fuck him.
Bruce wouldn’t lie, seeing Clark let go was a sexy prospect, but he refused to make it easy for Clark. It wouldn’t feel right for either of them if Bruce simply rolled over and let Clark fuck him.
Time passed like a crawl as Bruce stayed still. All he could think of was that he was the prey in this situation, and his usually sweet boyfriend was the predator hunting him. Most people would be terrified - Bruce was getting aroused.
It was almost the end of the hunting period when Bruce heard a loud sound. His heart started racing before the tree holding him began to move. Bruce quickly slipped out of the indent and landed on his feet, seeing Clark looming above him, floating and holding the tree in one hand. He threw the tree as Bruce turned and began to run, knowing that he couldn’t outrun Clark, but he refused to give in easily. Clark landed on his feet and ran towards him.
When Clark grabbed his shoulder, Bruce wiggled in his grasp as they tumbled to the dirty ground. Clark wasted no time throwing pieces of Bruce’s leg and crotch armor off as they wrestled, getting his bottom half naked quickly. Bruce fought back, biting Clark’s arm and kicking as Clark pushed his legs apart. With his superspeed, Clark pushed down his trousers and underwear before turning Bruce over onto all fours. Bruce had prepped himself before their primal play, lubing himself up so Clark wouldn’t have to wait. Clark didn’t waste time and sharply thrusted into his boyfriend.
Bruce growled as Clark pushed deep and fast. He bottomed out quickly, leaving Bruce feeling a slight burn from the speed of it all. Clark quickly snapped his hips and began thrusting vigorously, pulling Bruce’s hips hard and leaving marks that would definitely bruise. Bruce tried to turn and kick Clark, but Clark caught his leg and pushed it upward, deepening the angle of his thrusts. He also placed a hand on Bruce’s cowled neck as a warning. Clark threw his head back and fucked hard, with the sounds of sex echoing all around them.
Their fucking was animalistic, it was primal and raw, it expressed years of obsession and love and pent-up emotions. Bruce came untouched with a grunt. As Clark approached his orgasm, he growled and bit into the meat of Bruce’s raised thigh, causing Bruce to hiss. Finally, Clark came, his hot cum rushing inside of Bruce as Clark continued thrusting. Finally, he pulled out, causing the cum inside of Bruce to spill out slowly.
Clark panted and finally got in control of himself. He spoke, “Bruce…how do you feel?”
Bruce struggled to sit, speaking with a straight face, “Like I was fucked by a train.” Clark cracked a smile and he laughed, causing Bruce to crack a smile too.
Clark told him, “I love you. Let’s get dressed and I’ll take you back to my apartment and pamper you. You probably want some gentleness after I fucked you like an animal.” Bruce nodded. Once they gathered all the pieces of his leg and crotch armor, Clark carried him back to his place bridal style for some much needed tenderness after their rough primal play session.
Clark and Bruce were definitely on board for doing this again.
