Kyle staggered up the steps like his leg was braced, his huge bestial cock barely soft after firing down the leg of his jeans. The material was drenched and clinging to his flesh, warm whitish globules dripping out the cuff, in and around his shoe and leaving a sticky footprint on the hardwood finish with every step. His swollen testicles ached as though he'd been kept on the edge for hours, despite that last, desperate explosion. Despite both of them, he corrected. What his friends had to be going through now had been shut out of his mind as he climbed towards the bathroom. Just to clean up, he told himself. Just to clean up and nothing else...
He kept repeating that in his head as he reached the upper story and moved down the hallway, shut his eyes and whispered it. "I'm just cleaning up... I'm just cleaning-"
He had fallen before he realized what was happening. He scrambled to get his bearings and realized there was something under him, whatever it was he had collided with.
"Ow! Jeez, get off of me!"
Hearing that voice froze Kyle's heart. His little brother Corey.
He pushed himself off the fourteen-year-old boy and looked down his body. Corey was wearing nothing but a white undershirt and briefs. As he'd laid on top of him, Kyle had managed to smear his stallion's seed all over the boy's legs, even into his groin. The drips of cum glistened in patches over the downy hairs, soaked into the white briefs.
Of course. Corey had been getting over a cold this week. He was better but his mother had kept him home another day in case he was still contagious. Kyle had just forgotten. So much had happened...
"Ah, sick!" Corey started trying to brush the wet, sticky fluid from his body. "What is this? Why are you all wet-"
Kyle's heart went from frozen to a hideous pounding. He felt faint, almost wished he would faint, and felt his cock begin to harden again as his brother gaped at the malformed bulge. His mouth dry, Kyle could only return the stare to Corey's crotch, already knowing too well what was about to happen.
