You would think this would go without saying, but anyway, I don't own Teen Titans or any of the characters (Except Crow. I made Crow). By the way this story takes place three years after the series.

"Alright team," said Robin, "lets call it a day."
The Teen Titans had just had a long day fighting villains, (when will control freak finally give up?) and were very tired. Beastboy plopped down on his bunk-bed. Robin decided to skip practice for the night and do twice as much tomorrow morning. Cyborg double checked the security and then went to recharge. Terra lay down in her room for the night. Starfire fed Silky and retired as well. All turned in for the night.
Except one.
Raven was standing by her open window, an uncharacteristic smirk played across her face.
"Ahhh... I haven't felt this good in while. Now... what mischief can I cause while I'm here?", she mused darkly.
Her smirk changed to a wicked smile. I do hope your comfortable in there, she thought inwardly, Just sit back and enjoy the show.
Raven concentrated for a moment, letting her power flow to a certain area of the tower. She was rewarded a moment later with a scream and the sound of laser-fire. She smiled, put her hood up, and sank through the ground to "help" her friend.

The Next Morning:

"Okay Cyborg," came a very unhappy Terra, "Have you figured out why the security system went ballistic all over my room last night?"
Cyborg sighed. "I don't have a clue. Their was a couple of damaged circuits, and that's why the guns went haywire, but I don't know how they were damaged."
Robin was deep in thought. "Its odd that the guns went off only in Terra's room. That suggests sabotage... or possibly attempted assassination."
Terra gulped. But Cyborg shook his head. "Those guns can be set to target certain types of material. They were set to destroy only non-living targets. Thats why Terra's room was completely demolished. So... either it was a simple malfunction, or someone's attempted assassination screwed up."
Terra looked around nervously. "Sooo... how long until my room's fixed?".
Cyborg leaned back on the sofa. "Probably about a week."
"So where should I sleep till then?"
Cyborg thought for a moment. "Well, you could sleep in one of the spare rooms, but since the attack was specifically against you..."
Robin finished for him. "It might be better if you were near someone else on the team."
"Soooo... she should stay in one of our rooms?" asked Beastboy.
The others looked at Beastboy sceptically.
"I think it might be best if Terra stayed with one of the other girls." Robin stated.
"Oh, oh, oh!" cheered Starfire "Terra, you can stay with me! We can stay up, and comb each others hair, and tell embarrassing stories, and partake in the painting of each others toenails, and-"
Terra's expression changed from slight discomfort to utter panic. She looked around pleadingly to her fellow titans.
"Starfire, maybe it would be better if Terra stayed with me." offered Raven.
Terra was grateful to avoid the fate of sharing a room with Starfire, but was still startled by Raven's offer. Nevertheless, she accepted, and the two went to move Terra's belongings.
"Whoa, did anyone else catch that?", piped Beastboy, "I thought Raven never let anyone into her room."
"Yeah, man, what's up with that?" agreed Cyborg.
"Maybe she just felt like helping out." shrugged Robin "Come on, that room isn't going to fix itself."

That Night:

"Thanks for letting me stay here till my room is finished Raven." said Terra.
Raven smiled darkly behind Terra's back. "My pleasure, Terra."
Terra turned around at this. That certainly didn't sound like something Raven would say. "I am a little surprised that you offered though."
Raven shrugged. "I guess I wouldn't want anyone to have to suffer through Starfire's 'female bonding'."
Terra laughed. "Well, we may as well get some sleep." She said. Raven nodded, and the two girls got ready for bed. Once the two were ready to sleep, they lay down in Ravens bed(which, thankfully, was easily large enough for two people.).
Raven was lying in bed with Terra's back to her. Well, what you think? She thought again. Not a bad plan, huh? And it seems like everything turned out just like I wanted. Now I'll give you show.
Raven reached over and pulled Terra into an embrace. Terra jumped at the contact.
"Raven, what are you doing?"
Raven reached around Terra and started rolling the girl's nipple between her forefinger and thumb. Raven's other hand reached down to Terra's crotch and started rubbing that sensitive area. Terra let out a surprised cry and shoved Raven away.
"What the hell's gotten into you?!"
Terra then saw Raven's smile. An evil grin like the one that a mastermind wears when he knows something the hero doesn't. This did not seem like Raven.
Suddenly, tendrils of dark energy wrapped around Terra's wrists and ankles, rendering her immobile. More dark energy went around Terra's whole body and, with a slight jerk, tore Terra's clothes apart. Raven stopped to admire her friend's naked body. She reached out and cupped Terra's breast in her hand, giving it a little squeeze as if checking the freshness of a piece of fruit.
Terra moaned. She was now far past alarmed, she was starting to get truly frightened. "Raven snap out of it! What the fuck are you doing?!"
Raven ignored Terra's voice and began to disrobe. Terra started getting uncomfortable as she watched her friend take off her clothes. Then dark energy covered the entire room except for the two girls. Raven looked up from her work and smiled at the confused Terra. "I'm just sound-proofing the room. Now you can scream all you like." Raven had nothing left on her body but her underwear. She reached around behind her and unclipped her bra, letting it fall to the floor. Now Raven's well formed breasts were exposed.
Terra finally started to realize that (for whatever reason) Raven was about to rape her. Terra took in a deep breath and found her voice. "Raven, I don't want to hurt you, but if you make me..."
Raven laughed loudly, startling Terra once again (Raven almost never laughed, and never in such an unrestrained manner). "You really don't get the situation you're in, do you Terra? We are five stories up. There is no way you would be able to lift up individual rocks from this distance. Even if you could," Raven said as she tapped on the window, "my powers have reinforced this whole room. You would never be able to break through."
Terra bit her lip. Then she got an idea. "I could still collapse this whole tower!"
Raven almost doubled over with laughter. "And what would that accomplish? You'd hurt the others. Sure, Cyborg and Starfire would be fine, and Beastboy could probably morph into something sturdy, but Robin's only human. And for that matter, so are you. You would be hurting yourself. Besides, I'd be fine. I could just put a shield around myself. You'd be doing more harm than good."
Terra cursed. So much for that.
Raven then began to roll down her panties. "I think it's time we got started."
Terra was about to retort, but what she saw just then didn't even register for a moment. After Raven pulled down her panties, revealing her cunt, their was a sound of rubbing flesh, and a long, hard, male penis slid out of Raven's pussy. Terra's jaw dropped.
Terra's emotions shifted wildly, first to surprise, then to disbelief, then to horror. Raven's smile widened. "Your expression is totally priceless. You humans are so entertaining." The tendrils around Terra's wrists turned her over so that Terra's butt was facing Raven.
Terra's mind was racing, but then a thought struck her. You humans? True, Raven was not technically human, but she almost never referred to herself as being above humans.
Terra turned her head as Raven knelt down behind her.
"You're not Raven."
Raven smiled at Terra.
"Oh, I'm Raven. Just not the one you know."
With that she plunged her member into Terra.
