It was mostly quiet, titans tower completely calm. As with the defeat of the legion of evil, the recruitment of multiple titans, and slade finally defeated(by some guy named wade or something) finally allowed the titans some time to relax. It was the middle of the night, almost every titan asleep. Robin was in his bedroom, wearing the night attire that starfire bought everyone. He felt something on his face(especially since he wasn't wearing his mask) and woke up to his vision being almost completely obscured. It was a card…from starfire.

Robin,

meet me upstairs at the pool

Come alone

I have a surprise for you

Starfire️

Robin blushed abit. He and starfire had been pretty promiscuous in the pool lately. Mostly make out sessions and occasional groping. He hopped out of bed and changed into his swim trunks before grabbing a towel and heading to the elevator. Rather than a collection of buttons, cyborg modified it with a touch screen of titans tower(complete with hidden entrances only the titans could access and a display of every major room). Robin tapped on "pool room" and jolted a bit as the elevator moved up to the requested room. A few seconds later, Robin stepped out onto a room with a lap pool, a sauna room in the corner, two hot tubs to the side, a shower room in the corner, and a stand with several towels for each titan. Robin noticed the room was quiet and was wandering if this was another one of beast boy's dumb pranks. His assumption was latter proven wrong as a red haired alien resurfaced and rested on the tile edge of one of the hot tubs. Robin blushed and grabbed a towel. He didn't step in any puddles which meant starfire must have been the only one here, as beast boy and cyborg would have been cannon balling while Raven was in the sauna trying to get some peace and quiet. He set his towel down on a chair and walked to the stairwell. Starfire noticed and grinned as her boyfriend sat across from her in the hot tub. Robin noticed Starfire was deep in the hot tub, with only her head and neck visible, which he found a little odd but nothing more typical than what he fights every week. The bubbles felt nice as he set his lower back against one of the bubbles jets.

"I see you got my letter." Starfire whispered

"Yah, you wanted to see me." Robin replied

"Yes I did." Starfire said as she leaned closer

She slowly placed her hand on robin's shoulder and the two shared a deep kiss. Starfire was moaning through her lips and the two started to warm up. The two parted lips and pressed foreheads for a bit before Starfire pulled away and sat next to him, feeling up and down his chest.

"Robin, there's something I've wanted to tell you." Starfire said as she stood up a bit

"What is it star?" Robin asked

"I think it's time we take our relationship to the next level." Starfire said

She then looked back at the door to make sure they were all alone. Starfire then swam back a bit and stood up. Robin went wide eyed as Starfire was completely naked. He was expecting her to wear a skimpy yellow bikini or something but this was even better. Her figure was slim but toned, bee butt sculpted and smooth, her breasts were enormous(EE cup), and her cave was shaven and smooth.

"I don't know what exactly has come over me, but I just knew this would be the perfect time." Starfire said as she kissed his cheek.

"Star, I think your right, let's take it to the next level." Robin said as they kissed again

While making out, Starfire started to tug on robin's swim suit. They came off after a few strong rugs and Starfire grinned at what she saw under the water.

"Oh, this is going to be most enjoyable." Starfire said as she tossed robin's trunks away

The two's breathing started to speed up as they started to kiss more passionately. Starfire wrapped her legs around robin's waist and looked at him like she was waiting for an answer. He gave a nod and she grinned. She then positioned herself and went right in. She groaned and wept a few tears. She was still for a minute, her grip on his shoulder gradually getting softer. She took a deep breath and looked up to him smiling at her. The two started kissing again as they went to work. Starfire was thrusting hard into robin, the water rippling and waving with every motion. Robin had grabbed onto and was squeezing her rear, each hand full of soft cheek. Starfire was now blushing deep red and moaning very hard. She was so entranced with pleasure she bit down on robin's shoulder. To her surprise he actually liked it and she kept nibbling. Their thrusting was now getting harder, the water starting to splash out of the tub onto the tile around them. Robin turned the jets on full blast and the tub was bubbling like it was going to erupt. Starfire was thrusting faster now, getting closer to her very first climax.

"Robin, spank me please." Starfire asked

Robin did what she wanted and spanked her as hard as he could(as hard as you can when your in the water anyway). Her passion and pleasure building exponentially with every movement. Robin now put one of her breasts in his mouth and suckling on it while caressing the other breast.

"Robin, I feel strange, I think I'm going to ahhhhhhhhhhhh." Starfire tried the say

The two felt their muscles tense up and their legs going weak as the finally climaxed. Starfire was moaning for a solid 30 seconds before finally resting on robin's shoulder

"Robin, that was glorious." Starfire said panting

"Yah, it was." Robin said coughing a bit

"This was a great idea if yours Star." Robin said as he hugged her

"Oh don't get to comfortable, we're doing that again." Starfire whispered in his ear
