A sneak peak at the beginning of the next part, as my blog followers (NSFW)

“Jim, this is not appropriate,” Spock protested, flushing a light green.

Jim was straddling him on the chair in Spock’s office. Fully clothed, though.

“Oh, come on, Spock. You don’t have another class for an hour and a half.”

“True but…computer lock door.”

The door of his office sealed shut.

“You are incorrigible,” Spock murmured but without much heat behind it. Instead, he slid his hands up under Jim’s red cadet uniform. Jim leaned forward and kissed him.

“I haven’t seen you since—”

“This morning,” Spock said. “As you were leaving my apartment. Late for your class, I might add.”

Jim grinned. “You sound proud of that.”

Spock shrugged a little. “You ignored the alarm so I found a more creative way to ensure you were awake.”

Jim traced his tongue along his bottom lip. “It definitely worked. And now, well, I’m here to pay you back.”

Spock’s brows furrowed. “I require no gain for the enjoyment of our intimate activities.”

“And wasn’t that a mouthful.” Jim shook his head and chuckled. “I love Vulcans.”

Spock inched a finger up Jim’s bare torso, well bare beneath his shirt. “Do you?”

“Uh-huh. The snooty way they talk. The snooty way they look.”

“Snooty? Is that a scientific term?”

“Completely. You even flirt snooty.”

“Indeed.”

“And the incredibly hot way they fuck. That’s my favorite part.”

Spock’s lips curled upward. “Mine as well.”

“I can tell,” Jim said breathlessly, as he wiggled against the hard bulge in Spock’s professor trousers. He reached down and undid the fastening of Spock’s pants. He slid down off Spock’s lap and to the floor directly in front of him.

“Jim.” Spock’s dark eyes were wide, his pupils dilated.

Jim looked up at him through lowered lashes. “You aren’t going to protest, are you, honey?”

Spock swallowed. “No. I just wanted to ensure you were comfortable.”

“Oh, I think I’m okay. And this won’t take any time at all.”

“Are you…that good then?”

“You know exactly how good I am, professor.”

Spock moaned as Jim pulled out his straining erection from the confines of his trousers and briefs. The head glistened with Vulcan pre-cum, which Jim had discovered was quite the delight. He flicked his tongue out, tasting the spicy, tangy slick.

“God, I love your taste. I really good suck your dick all damn day.”

Spock said nothing but stared intently at Jim, his face flushed, his lips pursed and looking insanely defiled.

Jim held his gaze as he closed his mouth over the double ridged thick head of Spock’s cock, sucking him in deeper, deeper, until the tip hit the back of Jim’s throat. He fought the gag reflex and won.

Spock’s ass rose up out of the chair as he arched up into Jim’s mouth. His fingers spread into Jim’s hair, as Jim knew they would, for Spock loved to hold Jim’s head as he fucked into Jim’s mouth.

In the month and a half they’d been together, Jim had learned Spock wanted to be in control, wanted to dominate, and was very vocal during sex. Of course Jim fucking loved all those things. It was like Spock had been made from the heavens for him or something.

“Jim,” Spock groaned. “Yes, Jim. Yes.”

He rolled Spock’s balls with his finger eliciting another needy moan from the Vulcan’s lips. He winced a little when Spock’s grip on his hair tightened as he rammed himself frantically between Jim’s lips.

“Jim. Jim, please. Jim. Jim!”

Jim sucked harder, deeper still, Spock’s tangy, spicy taste urging him on for he couldn’t wait for the Vulcan’s fluid to fill his mouth, coat his tongue.

Then Spock tensed, crying out Jim’s name one more time on a ragged moan and his cum began to splurt out into Jim’s mouth. He greedily sucked Spock dry, feasting on the softening cock, until Spock finally pulled out, pushing Jim away.

“Too much,” Spock rasped.

Jim grinned and wiped his mouth. His own dick was painfully hard as he stood and sat on the edge of the desk facing his lover. “You’re incredible.”

“I believe it is you who have earned that title.”

Jim dodged Spock as he went to reach for him. “Nope. Can’t.”

Spock’s brows furrowed. “But—”

“I’m meeting Bones for an early dinner later and I’ve got some stuff to do before then.” Jim leaned down and pecked Spock’s lips. “You want to join us?”

“I am not certain the doctor likes me,” Spock said doubtfully as he did up his pants.

“The doctor likes you.” Jim grinned. “Will you?”

“He is a significant part of your life, therefore, I should become used to him.” Spock made a little noise which Jim knew was his version of a sigh. “I will need to shower and change.”

“Is that a yes?”

Spock nodded. “Very well.”

Jim whooped which made Spock look snooty again. It was such a great look on Spock too. Debauched snooty Vulcan.

“I love Vulcans.”

Spock’s lips twitched. “Yes, you have said so.”

“Well and especially one in particular of course.”

“I had assumed so. Will you come to my apartment after dinner with the doctor? I find that I need to punish you.”

Jim’s lungs seized and he licked his lips, starting at Spock. “P-Punish me?”

“You are a very bad boy. Such insubordination.”

“Yes.” Jim cleared his throat, feeling a little lightheaded. Probably because all his blood was in his dick. “Definitely yes.”
