DISCLAIMER: I DO NOT OWN TEEN TITANS!

Later that night on the roof after an amazing birthday, Starfire found Robin pacing back and forth. The subject from earlier had not yet left Robin's mind, and he was clueless as to how to tell his sweet, innocent Starfire what these things were that she wanted to know about.

"Robin! Is something troubling you, friend?"

"No, I'm just thinking." Robin replied, lying only a little.

"About?"

"Those questions earlier." Robin said, and Starfire nodded, making her bangs cover one of her eyes. Robin, not thinking about his actions reached out and pushed the bangs out of her eyes, placing them behind her ear. His hand dropped to her neck, feeling her pulse there.

Suddenly, he realized that these were not just things he was doing in his mind, and went to withdraw his hand. Starfire grabbed it though.

"Star?" Robin questioned as she laced her fingers with his.

"Robin, I am not a child, and I'm not clueless. I may not know what making out is, or what sex means on your planet, but I do know what a kiss means here, and I know that the kiss I shared with you upon my arrival was not just made so that I could gain knowledge." Starfire whispered, gazing at his mask. Frustration mounted inside her at not being able to see his eyes.

"Star, I…"

"Wait, Robin. If you are to talk to me out here, just person to person, don't hide from me."

"I'm not hiding."

"You're eyes are." Starfire commented, and Robin sighed. He reached his free hand up, peeling the mask off and letting it drop to the roof. Starfire gasped. His eyes were gorgeous. They were a Caribbean blue, with a sea-green circle around the inside.

"Is that better?" Robin asked, and Starfire nodded, lost in his eyes.

"Listen Star. There's something I haven't told you, because… well, because I was scared to."

"Yes?"

"I love you Star."

"I love you too, Robin." Starfire responded.

"No, you don't get it. I don't love you as a best friend, or even a sister. I love you as so much more." Robin said, and Starfire hugged him.

"I know, and I love you as well." She giggled into his shirt.

"Really?"

"Yes." Starfire responded, and she stood on her toes as to reach his soft lips.

"Robin?" She asked after a moment.

"Yeah?"

"I am still waiting for answers to my questions." Starfire said, and Robin tried to think of an answer, then his eyes lit up with an idea.

"Well, sex is… way too complicated to explain right now. But as for making out, it's easier to show then to explain." Robin said, smiling slyly.

"Show me then." Starfire replied, completely clueless. But damn if she wasn't cuter when she was clueless. Robin stepped closer, locking his arms around her waist. On instinct, Star's arms encircled his neck.

Robin's head bent down, and his lips met hers, gently. He didn't want to shock her into backing away from him. When she kissed him back, he kissed her gently once more before putting his hand beneath the back of her shirt. She gasped at the cold feel of his hand, and he took advantage of it.

Robin slipped his tongue into her mouth with the ease of a practiced person, even though this was the first time he had made out with a girl with whom he actually wanted to. Starfire tensed, unaware of what was going on, but soon found that she enjoyed the feeling of his tongue sweeping through her mouth and relaxed.

Deciding that Robin had had dominance for too long, Starfire pushed on his tongue with her own. Robin pulled his tongue back in his own mouth, afraid he had scared Starfire in some way, but she then flicked her own tongue into his mouth, wandering, tasting, wanting more. He groaned when her tongue retreated, and she pulled out of the kiss.

Unable to deny the want inside himself, he kissed across Starfire's jaw, and then down her neck. She shivered as his tongue darted out quickly, and she moaned; then covered her mouth with her hand, unfamiliar with the sound. Robin removed her hand and kissed her lips gently.

"Its okay, Star, that's a good sound."

"It is?"

"It means you're enjoying this." Robin said, slipping his hand under Starfire's shirt smoothly. She pushed back on his hands though.

"Sorry, I guess I got kind of caught up in the moment." Robin sighed, thinking he had gone too far.

"I didn't say I didn't want that… it's just, you've been doing everything. I'm supposed to be the one learning." Starfire whispered, having had stood on her toes to whisper into Robin's ear. She kissed the area right below his ear, and he shivered as Starfire allowed her fingers to trace the muscles of his stomach beneath his shirt.

Suddenly Robin pushed her back.

"Star, stop." Robin said. Starfire's hands had been traveling towards the waistband of his jeans, and he wasn't ready for that much that fast.

"I'm sorry." Starfire apologized, dropping her eyes.

"It's okay Star, I just don't wanna get you pregnant right after admitting my feelings for you."

"The making of out can get you pregnant?"

"No, but it can lead to other things that can."

"Oh." Starfire replied, and Robin leaned in, kissing her chastely. Starfire shivered, but not because of Robin's kiss.

"C'mon. It's late, and cold. We better get inside." Robin said, and Starfire nodded.

Little did the two know, someone was watching the whole scene, already contemplating a perfect plan for revenge on the Boy Wonder.
