Silas gets jelly.

Silas was feeling good about himself lately. His efforts to emulate Kamui, and eventually replace him were paying off. He'd even managed to win over his ferociously affectionate sister, Camilla.

Yes, now there was a prize. With her perfect breasts, gorgeous hips and beautiful hair, sometimes he thought if he got more than he bargained for. But then he remembered that Kamui would never have her, and all was well.

Silas headed for the springs, some late night training had done wonders for overcoming his excitement. Tonight was the night. The night where he finally took part of Camilla's love, after a quick soak in the relaxing waters.

"h...ah..." Silas stops, a few meters from the springs location. If anyone was nearby, they wouldn't be able to see him quite yet. The shrubs nearby were plentiful, and served as cover from prying eyes. But pry he must.

"Ah....yes.." He creeps closer, trying to figure out who could possibly be in the springs at this hour. Then a chill goes down his spine. "Kamui....Kamui....yes!" It couldn't be. Kamui? At this time of night? Now he had to know who else was in there with him. He was unable to shake off the knot in his stomach as he crept closer.

What he saw, stunned him. There she was, in all her nude glory, his dear Camilla. Hair, wet, framing her face and body. Making a face he'd never seen her make before. Eyes, shining in a way he's never seen. Face flush and red. And in the mist, right behind her, was Kamui. Thrusting with a passion that Silas had only seen on the battlefield.

"Ah~AH! Yes! Gods Kamui YES!". Silas couldn't believe his eyes. The man who he always pretended to admire, was here. With his wife.
"What would Silas think?" he hears Kamui ask, without slowing down. "I don't care what, ah~, he thinks ah~". She bit her lip as Kamui sped up. Slamming his cock into her with a ferocity Silas would never be able to match. "I only belong to you, ah! Kamui!"

Silas felt time stop. "There's no way" he thought. "She can't mean that". But her face confirmed his fears. There was nothing but love in her eyes, as she locked them with Kamui's, mouth wide open in ecstasy, showing how much she truly enjoyed this.

Even so, against his will, he felt his own member harden. "What is happening" he thought, still unable to accept what was happening before his eyes "Why do I feel this way". He reached down and grabbed his cock, still peeking through the shrubs. The way her breasts bounced with every thrust, her moans, the way she took Kamui's cock with ease, biting her lip harder and harder, only served to drive Silas to a breaking point. With tears of frustration in his eyes, cock twitching in hand. "Ah~ I'm coming KAMUI!"
With frustration and jealousy, Silas came. Harder than he ever had before, at hearing his beloved utter scream those words at Kamui. Without saying a word, he wrapped his towel around himself, and walked back to camp. Heavy of thought, and full of rage.
