"Suprachiasmatic nuclei."
"Um . . . that enables your 25-hour body to function in a 24-hour day."
A little nod of the head was the only response Justin received as Brian moved on to the next notecard. Justin was amazed that he had been helping him for so long and for the most part without interruption.
"Hypothalamus."
For a moment, Justin was silent with his pondering.
"It regulates hunger, thirst and . . . um . . ."
Raising an eyebrow, Brian completed the definition.
"Sex drives."
"Yeah, yeah," Justin said snapping his fingers as he remembered. "Okay . . . go on."
Brian sighed and threw the cards down on the table between them.
"Hey" Justin questioned. "I thought you were gonna help me."
"I will once your hypothalamus wakes up," Brian answered as he walked away.
Justin rolled his eyes and opened his psychology book. He had a big test the next day and all the brain parts and their functions were giving him a hard time. He couldn't keep all the longwinded words straight. Midway through his review of the different parts of the motor cortex, he felt Brian's hands slide down his arms and lips at his ear.
"This is really interesting," Justin said ignoring Brian's attentions. "Did you know that it's the left side of the brain that controls the motor skills of the right side of the body?"
"Hmm," Brian mumbled into the skin of his neck. "Fascinating."
"So wouldn't that mean that - "
Justin was unable to finish his sentence as Brian covered his mouth with is own and began to rub his chest with his hands, soon moving under the shirt to feel the soft skin underneath.
"Come on," he whispered. "I think your hippocampus needs stimulation."
"Hmm, hypothalamus," Justin corrected against his lips.
"Whatever," Brian nearly growled as he pulled Justin towards him.
