Calvin lay there in bed, next to his tiger. His fourteenth birthday was tomorrow. He was getting older, puberty striking at his mind, voice, and body. He kissed Hobbes on the cheek, puling him closer and thanking him for being his friend.
Then it happened. It had been happening often since he was thirteen and he had no control over it. His erection tented his boxers, pressing against his friend's rump.
"Stop.." Hobbes mumbled with a growl, pushing him away.
Calvin turned onto his back, pulling his under shorts down and revealing his standing pillar, about five inches. Average, he figured.
He shook Hobbes awake. He didn't wake easily and grumbled and growled, but eventually sat up. "What, Calvin?" He asked angrily, wanting very much to go back to sleep.
"I love you."
"I love you too.." Hobbes said awkwardly. 'What is this about?' He wondered.
"Do you really love me?"
"Yeah, why?" Hobbes sat up further, sleep forgotten.
"I want to mate with you.." Calvin blushed.
At this point, Calvin felt incredibly aroused, but surprisingly powerful, and thus, Hobbes is a submissive, but still incredibly aroused figment of his imagination. Hobbes could feel every inch of Calvin's cock sliding into his tight little asshole, and about Calvin pulling Hobbes' arms behind him as he licked and sucked the back of Hobbes' neck, holding him down as he fucked him. Calvin slides every inch of his cock inside Hobbes, and fucks him hard and fast while Hobbes moans his name and begs for more. Hobbes really needs to show Calvin he's his little bitch. After minutes of taking Calvin's long, hard cock, Calvin proceeds to fill Hobbes' little asshole. The feeling of Calvin's cock and its hot, sticky cum shooting inside him causes Hobbes to gasp out-loud and cum hard, squeezing around Calvin's cock. The two fall onto the bed, exhausted but satisfied, as Calvin wraps his arms around his Love. "I love you." says Calvin, as he strokes his tiger's fur. "I love you, too." responds Hobbes, as they both fall into a gentle sleep.
