The bet.
It was the same every Friday morning. Luke would head down to the heated pool and swim for about an hour. But he never went there for the warm water, nor the exercise. He went there to win his weekly bet. The orca stretched as he entered the locker room. He stripped down and changed into a pair of dark grey speedos, so close to his colour they almost blended into his skin. His visitor arrived.
The wolf, Colin, entered the locker room. He was lightly built, with the faintest hint of abs. His fur was light grey, and was lighter around his chest area. He wore a pair of loose blue boardshorts.
"Ready for the bet?" Smirked Colin. Luke returned the grin.
"Of course." The two headed out the doorway leading to the pool. What they bet on was simple - whoever could perform three laps of the pool the fastest would win the bet. They were fairly evenly matched when it came to swimming. They both took their positions, and leapt into the water. After a length of time, the two swimmers emerged from the water - Colin with a disappointed look on his face.
They both returned to the locker room, and Luke pulled a twenty-sided die from his sports bag. He gave it a roll, and Colin watched anxiously. When it came to a stop, the word "DEEPTHROAT" appeared on the top. The two moved toward the showers, and stripped. Hot water soon covered their bodies and they began to make out, each mouth fighting passionately for dominance. Then Luke grabbed Colin by the shoulders, and forced him down to crotch level. The muscle dangling in front of him was half erect. It glistened as the hot water glided along it. The wolf opened his mouth licked it's underside slowly. Luke looked upward with closed eyes and a smile. The wold then slowly worked the head, suckling on it back and forth like a lollipop. Then, the orca put his hand on the back of the wolf's head, and pressed him down onto his cock hard. The wolf continued on his own after that, going all the way down the massive length, desperately sucking up the salty pre and massaging the cock with his thick flat tongue. The orca moaned with pleasure as each sliding motion ocurred along his length.
A few minutes later, the moaning grew louder, and closer together. He had to tense himself more than a few times to attempt to keep his load back, but it grew useless. A loud final moan followed by a grunt from Colin - The orca's massive load cascaded into the back of the wolf's throat. Bit's of hot cum that couldn't be swallowed dribbled out the wolf's mouth and got stuck in his fur. The orca smiled at the wolf dizzily.
But all Colin could do was look up, exhausted.
