Disclaimer: Kirk and Spock belong to Paramount who never let them have enough fun.

"Oh, God!" Kirk cried out as he spread his legs farther apart. "All of it Spock...I need you in me. Further," he begged. He lifted his hips even higher as he lay beneath the Vulcan. His chest gleamed with sweat, his nipples were taut, his hands were clenched at his side. His eyes shown bright with unshed tears, tears of joy and need. His check were flushed.

"Yes, Spock. Love me!" he shouted, the look of agony on his face bearing witness to his deep need.

Above him a no longer stoic Vulcan panted, "yes, yes. Jim. I am," as he thrust deeper and harder into the willing ass resting in the palms of his hands. He kneaded the hot cheeks in his hands, pulling them farther apart. He lifted himself forward on his knees using his greater weight to push him into the human.

Again he thrust and moaned as the human pleaded for more. "Good, so good. Spock. You make me feel so full."

Spock pulled almost out, then slowly slid forward as Kirk writhed beneath him.

"More, Spock. Please!"

"Slowly, Jim. Enjoy this."

"I need you too much."

"Feel me as I enter you."

"Oh yes, so hot, so hard. Tell me what you feel."

"Yes, my love," Spock responded automatically.

Kirk glowed at the phrase.

"You are tight and slick. When you clench around me, I feel an urge to thrust so hard."

"Do it," the Human pleaded.

Spock thrust hard, pulled back, thrust again. He moaned as the Human tightened his anal muscles refusing to let him out.

"You're mine, Spock."

"Yes, Jim. Always." Spock slid one hand around Kirk's hip, up and forward. He folded his warm palm around Kirk's cock.

Kirk jerked upward. "Oh god. No." His cock dripped as Spock stroked him slowly. He threw his head back and closed his eyes in pleasure.

Spock's hips remained still, his hot cock buried deep in Kirk. He flexed his abdominal muscles causing his cock to move powerfully inside Kirk as he stroked Kirk's achingly hard erection.

Kirk's eyes flew open. "Ohhh. That's good, Spock." His hand reached out, pulled Spock's hand from his cock, held it tightly. "Not me, my love. This time is just for you, inside me." He flexed his hips, retreating from the iron hard impalement, then flexed again forcing the shaft inside. He looked into Spock's eyes. "Just love me. I want to feel you inside me. I feel you so hot. Your cock in me. Your balls full and ready against my ass. Your curls, wet with my sweat, are rubbing my balls. God, Spock, I love you."

Kirk gripped Spock's hands and began to move his hips in a motion Spock soon joined.

Slowly, their bodies worked together, then harder, faster. Hot green shaft sliding into slick reddened passage. The Vulcan's sweat dripped to join the Humans' pooled on his belly. And still they moved. Until.

"Jim. Soon. Thou art mine."

"Ungh....mmm..."

Another thrust and retreat. A hot, longing look passed between them. "Fill me, Spock. Come in me. I need you to be a part of me."

"Yes," said Spock, his voice deep with passion, "Thou art all things to me."

Kirk looked up at the sweaty visage above him. He smiled through his erotic agony. "Give me your seed." Kirk's eyes teared, "I love you so much. I want you always." His body tensed. He looked at Spock with all his love shining in his eyes.

Spock pulled back, "Now, Jim," and thrust long and hard, his moan becoming a scream of agony and release.

Kirk felt the cock throbbing inside him, felt the heat within. "Yes, Spock. Yes. Your seed, your child. How I want you!"

"Oh, Jim," Spock moaned as he collapsed on his lover.

The feel of Spock's slick abdomen on his cock set off Kirk. He thrust upward against the welcome flesh and came, coating Spock's chest as he slumped. Kirk wrapped his arms around the Vulcan and rested his cheek against the sopping hair.

The two rested this way for several minutes, then separated and lay side by side for a few more. Eventually Kirk sat up, leaned over the drowsy Vulcan and grinned. "Wore you out, did I?"

"Indeed," the Vulcan barely managed to respond.

"Do you want to shower?"

"Uh."

"I'll take that as a 'no.' I've got the wipes, may I clean you up? You're a mess, you know."

"Jimmm mmm," came a sleepy reply, "shhh." Spock rolled over onto his side and fell asleep.

"All right," Kirk muttered, flipped off the light switch, and snuggled up to the Vulcan's backside before he drifted off to sleep.

Hours later Kirk awoke with his hand on the Vulcan's shoulder, a warm hand stroking his back. He tilted his head up and kissed the waiting lips.

The touch of the Vulcan's lips was soft, warm, and loving.

"Good morning, Spock," Kirk said before kissing him again, this time taking the kiss into passion. Soon Kirk was aroused and needy. He turned fully toward Spock, taking his face between his hands, thrusting his tongue deeply into the warm mouth.

"Jim," the Vulcan protested weakly, wrapping his arms snugly around the Human. "We need to bathe first."

"Later, Spock," Kirk insisted as he rolled his body onto Spock's chest, pressing his erection into his lover's, then stopping suddenly. "Ick!"

"Indeed."

"We're really sticky."

"Quite." Spock kissed Kirk lightly then pushed him upward and off. "Do you wish to shower with me?"

"I'd be pleased." Kirk quickly changed the sheets, shooing away Spock's offer of help.

Soon a clean Kirk knelt before a well-scrubbed Spock, water cascading over them, Spock's cock filling his mouth. "Mmm. So good," Kirk murmured as Spock thrust.

"Suck, Jim,"

Kirk did as requested, then ran his hands up Spock's thighs and cupped his balls in one hand, his ass in the other. Spock sighed and held the beloved head close as the cooling water fell.

"Jim. Stop. Jim!"

Kirk sucked harder.

Spock pushed him, "Jim, the water is cold. Please let us retire someplace warmer. I wish to concentrate on enjoying your actions." Spock cut off the water.

"Oh, no. I didn't notice. Guess I was enjoying myself too much." Kirk stood up, kissed Spock. "I love your cock, you know."

"Jim, please. Logic dictates that we dry off immediately. That part of me that you love is reacting badly to the cold.

"Oh no!" Kirk reached out and wrapped his hand around the deflating cock. "I'll keep it warm."

With his other hand he grabbed a towel and began to dry Spock. "Better?"

"Yes."

Kirk let go of his prize and dried himself off. "Come on," he ordered and led the way to the bedroom.

Once there, Spock turned him, pushed his butt against the bed frame and knelt before him. "I wish to taste you."

As Spock licked up the shaft, then engulfed the head between his lips, Kirk gasped. Soon Kirk grasped Spock's head and pushed him away. "Stop. I'm too close; I don't want to come this way."

Spock pulled away, "I want to taste you, Jim. It has been a long time."

"I just want you in me."

"I do not believe it wise to enter you again so soon," Spock responded, then relented at Kirk's sad sound of protest, "but it will still be possible for me to penetrate you, even if you give me this." Spock gently kissed the shaft of Kirk's cock waiting for Kirk's decision.

"Yes, dear. Suck me, then love me."

"Both methods are ways to share love, Jim. Do not forget that," replied Spock before he returned to his snack. With Kirk's cooperation, it took only moments for the hot Vulcan mouth to coax a climax from the throbbing cock. Warm Human semen spurted into the Vulcan's throat as he swallowed. As the softened cock slipped from his lips, he whispered, "Thank you, T'hy'la."

Spock turned the pliant Human to face the bed. He pressed his body full length against Kirk's, his erection centered between the muscular buns. He wrapped his arms around Kirk and kissed his neck gently, "Do you still wish this?"

Kirk pressed his hips gently backward and placed his arms over the Vulcan's. "Yes, he moaned. I need you so much."

Spock squeezed him tightly, "Then I shall give you what you need."

Kirk turned his head and kissed Spock, "I do love the way I taste in your mouth."

Spock's cock throbbed in response. He bent slightly and grabbed the open tube of lubricant from the bedside table. "Please tell me if I hurt you. We were not gentle last night."

"It won't hurt. I want you too much for pain."

"Promise me, Jim. If it hurts, you will tell me." Spock slid one slick fingertip between Kirk's buns, touched the small aperture. Kirk moaned. Spock pulled back.

"Don't stop, that was pleasure."

Spock slipped his fingertip inside. "You are warm, Jim." Kirk shivered, "and still moist. I can feel the signs of our last love- making."

Kirk gripped the arm he still held, his "yes" barely audible as his head fell back against Spock's shoulder.

Spock slid his finger in farther, slowly. "Does this cause pain?"

"God, Spock. More. Please," pleaded Kirk.

Spock pulled out the single finger, added lubricant to the his first two fingers and slid both into Kirk. "So soft, Jim. You are so smooth inside. Relax you sphincter, I must enter you."

"Now!"

"Soon." He slid the fingers in and spread them. Slowly he worked in lubricant and another digit. Once Jim tensed and Spock slowed, "Do you want me?"

"Always. Fill me, Spock."

Spock removed his fingers. Kirk turned in Spock's arms, kissed him gently. He took the lubricant and stroked it onto Spock's cock. He looked up into Spock's eyes, "Love me."

"I do."

"I love you so much." Kirk turned and bent forward over the bed.

Slowly Spock pulled apart Kirk's buns. He stood for a moment gazing at Kirk, his glance sliding from slick opening up the muscular back to shining hair and back. Gently he positioned himself and pressed forward. He groaned and ceased his movement. The muscles on the backs of his hands where they held Kirk's buns flexed; his buttocks tightened; all with the fight not to press forward.

"You're holding back. I can take it. Come into me."

Spock obeyed, sliding all of him into his lover. Kirk pushed back against him and Spock reached in front of Kirk, cupping the rejuvenated erection, stroking it and holding it safe from the hard edge of the Starfleet bunk. He began slow strokes into Kirk's ass timing each with a stroke of his hand. Soon his cock swelled further. His partner's groans of pleasure shifted to audible words, "Fuck me, Spock, love me. I need you. I want you to be a part of me." And as they came, whispered words, "I need your baby."

Cleanup was quick. Both washed and Kirk wiped the edge of the bed. Soon they lay in each other's arms.

"Jim, we must talk."

"I'm sleepy," said the blushing Human.

"Then we will talk in one hour."

That caught Kirk's attention, "All right. Talk."

"In the last two months, you have only allowed me to bring you to climax orally three times. It used to bring you great pleasure."

Kirk interrupted, "Still does."

"But you do not choose this. Nor do you wish to fellate me to climax, not do you wish to penetrate me."

"It's not that I don't want to, Spock. I just crave you in me."

"I have deduced that from your repeated pleas. While I enjoy fucking you and find your ass an extremely accommodating place to climax, I am concerned about your need for this act. According to the medical database, such repeated anal sex can prove dangerous to the recipient."

"Not these days, love. You're careful and we have the regenerator."

"Also, according to the same database, shifts in mating habits, the sudden desire to clean and tidy up for one's mate, and repeated requests for progeny may be indicative of a syndrome called 'nesting'."

"Nesting? I don't think so."

"Do you have an alternate theory to explain your recent behavior?"

"Have I been so different?" He queried. At Spock's raised eyebrow, Kirk blushed again and snuggled closer to the Vulcan. "I've always wanted to be closer to you, just lately I feel like I need to hold you inside me."

"Do you fear that I will leave you? I have read that Humans often express a fear of separation by trying to increase physical closeness. You should have no fear, I will not return to Gol. I have what I desire here."

"No, I'm not afraid. I know that we'll be together always. But sometimes I want something to bind us so closely together that we can't be unraveled." As he spoke, Kirk shifted his thigh across Spock's legs, then ran his hand down the hairy chest and abdomen to the soft, spongy mound. He cupped the cock in his palm and gently squeezed and stroked it.

Spock grabbed Kirk's hand, held it to his chest. "Do not attempt to distract me. We need to discuss this subject."

"Couldn't we talk while we make love?"

"You will not avoid this conversation today. We are bonded by my traditions and married by yours. Is this not sufficient?"

"Oh, Spock, it makes me happy to be yours, but I want something to be ours."

"We could purchase a home on Earth for shore leaves. You have mentioned this in the past. I would not be averse to this; we already own my dowered house on Vulcan."

"That would be nice. But it is not very personal. Can I think about this and get back to you?"

"No. I need to understand. You are not happy. Either I must provide you with additional love or physical stimulus or you must admit what you need, so that I may help you."

"I'd like the additional stimulus, please." Kirk wriggled closer and attempted to pull his hand free.

"Would it help you become more at peace?"

"No, you're right." Kirk rolled over onto his back, placed his arms under his head and sighed. "There is something I want very badly, but I don't think you will want it."

Spock turned on his side to watch Kirk's expression. "If you do not desire to verbalize, I will join us mentally. Would you prefer to meld."

"Oh, Spock. I'd love you to meld us. That's so special, but I'd rather talk about this. Kiss me, just once."

Spock did so, then pulled back. Kirk looked up at Spock, then turned to face the ceiling. "I want us to... I want ..." He took Spock's hand, held it tightly. "I want to have your baby."

Spock's eyebrow lifted rapidly. "I had thought those statements to be a part of your love-talk, in the heat of passion."

"At first I think it was, but lately I've found I really want it." Kirk turned to Spock, looked at him through lowered lashes. "Think of it, Spock. Part you and part me. Your eyes, my chin. Your brains, my intuition. He'd be perfect."

Spock was silent, his face blank, his eyes bright.

"Say something. Please. We'd love him, or her. It would bring us closer. Spock, please say something."

"It is a surprise to hear you speak of this. I want you to be happy, but this is..."

"Wouldn't you like to be a father?"

"Indeed. But I gave up those plans when we were bonded."

"We'd be good parents, Spock! Don't you think I could be a good Dad?"

"You are very loving, Jim. You would be an excellent father, but..."

"But there are ways, Spock. Your parents had you and that was almost five decades of research ago. Men have babies all the time," he pleaded with the Vulcan. He slid his body next to Spock's, gazed up into dark eyes. "I'd want to carry it myself, feel our baby grow inside me."

"No, Jim. You could not."

"It's done all the time, really. They implant the embryo and the expectant Dad takes hormones during the pregnancy. It might make sex a bit awkward, but it's only nine months. We'd manage." Kirk looked lovingly at Spock as he stroked his own abdomen. "I think that's why I want you inside me so much. I know you can't make me pregnant, but it feels like we're trying."

"Jim, no. It wouldn't work."

Kirk's eyes teared up. "Please."

"It is not that I am opposed to us having a child."

"You're not! Oh, Spock." Kirk gently kissed the side of Spock's neck.

"However, I do not believe that our lifestyle is conducive to child-rearing. And I would not choose to have a child and not raise it."

"Him, Spock. Or her. Not it. Our child. We'd manage."

"It is against regulations for children to live aboard starships and a pregnant, active duty, captain of the flag ship would be a first. I expect Starfleet would object."

"But this 5 year mission is over in 4 months anyway. We'll be reassigned to Earth, probably, while the ship is refit. We can apply for shore duty for the next few years. You know you enjoyed teaching at the academy. And headquarters could find a place for me. Or we could go to Vulcan if you think it would be better. Your mother had you there."

Spock leaned into Kirk and began absently caressing his hip. "There have been mixed species births on both planets since mine. Your humanity dictates that we should do this on Earth, if possible."

"You'd let me?"

"Jim, I love you. If you are willing to give up the stars to have my child, how could I say no?" He pulled Kirk closer, rocking his hips against the Human's. "May I?"

"Make love to me? Yes, always." Kirk pushed against Spock, his cock hardening with renewed desire. He reached for Spock's hand guiding it from hip backward and lower. "I need you, too."

Spock slipped his thigh between Kirk's, lifting the Human's thigh over his own. He tilted his head to kiss Kirk's forehead. "How soon can we begin this?"

"In a couple of months, Spock. We have to make arrangements and I'll need to start hormones. Then... Mmmm. Touch me again, yes." Kirk began to moan as Spock slipped one finger into him. "And there are new ships.... ahh...planned...mmm...that will take families. Our child with us.... oh yes...and the stars." With that the room became quiet of all but the moans of the two lovers.

One year later, Amanda held a tiny bundle. "Sarek, look," she cooed, "She has Spock's eyes..."
