Bruce worked in his new lab in Stark tower, Tony had been so generous to let him live with him and pepper. He really liked that man, as a friend of course, even if he was secretly gay...
The hour approached 4 in the morning and poor Dr. Banner was exhausted, he shuffled to his room, not bothering to turn on the light, got undressed and fell into his bed.
About 10 minutes passed and Banner was shocked to find a body with him in the bed, pressing against his naked scientist body. Bruce dove out of bed and switched on the lights, looked back to his bed and saw Loki, god of tricks; lying on his side, with his head propped up and a red rose stem in his mouth, staring at Bruce hungrily. Banner blushed 50 shades of red and tried to cover his crotch with his hands as he noticed Loki was naked as well.
The god spat out the rose and said in a charming voice "So glad you've joined me, Hulk, now I see why they call you incredible..." The naked man blushed even more and tried harder, to no avail, to hide his growing erection of shame. "Oh don't be shy darling, I know you yearn for my touch... The untamed beast... I've dreamed of this."
Banner's eyes widened and he shook his head, unable to speak because of his pure shock and terror that Loki had found out Bruce had a crush on him. Loki curled his finger in a "come hither" motion and Bruce felt himself moving toward the bed, as he felt Loki's magic lay him down tenderly his hands pinned to his sides, revealing his weirdest boner. Loki grinned maniacally and licked his lips "I'll show you why they call me silver tongue"then he bent over and took Bruce's throbbing member into his lying mouth.
Bruce came almost instantly, Loki was the god of trickery, lying AND sucking cock. The horny god swallowed every last drop while looking into Banner's eyes. His still erect penis popped out of the tricksters mouth and flopped onto his stomach, still dripping wet. "Loki..." Bruce breathed, the god smirked and kissed his cheek then said "Flip over..." Bruce complied and got on his hands and knees in front of Loki, begging to be anally defiled. Without warning he said "Bite the pillow, I'm going in dry!" and rammed his girth into the scientist. Bruce shrieked with an almost girly tone and did indeed bite the pillow. The passionate god thrust in and out of Bruce, causing blood to act as a lubricant and smooth the shameful act. Loki yelled "Who's a puny god now!?" while still slamming into Hulks ass "You. Will. Kneel!" he said with each powerful thrust. Bruce was still screaming but Loki noticed his tone had changed, then his skin began to turn a pale green "You have to fight it, Banner!" he said, nearing climax. Just then, Iron Man burst into the room to see what the commotion was about and saw the horrid display "I'm telling Thor!" Loki screamed "YOU LEAVE THAT POPTART LOVING FAGGOT OUT OF THIS!" and still thrust on.
Then, both Loki and half-Hulk half-Bruce screamed with a thundering simultaneous orgasm, spilling their hot baby batter all over each other and the sheets. With an explosive CRACK the door to Bruce's room flew off the hinges and hit the farthest wall, Thor burst in screaming "ODIN DAMMIT, LOKI I TOLD YOU TO STOP FUCKING THE AVENGERS!" Loki slid out of Bruce's damaged anus "ehehehehee!" and crawled, naked, out the window.
Iron Man walked over to a fuming Thor and said "So... your brother just butt-fucked the Hulk. This normal for you guys?" Thor replied, disgusted beyond all belief "He's adopted..."
Bruce woke up hours later, blood and semen dried on the bedsheets "Loki..."
