Latex Seduction
(A/N: I just want to clear something up: This is, in actuality, a Rob/Star fic, it's just labeled as Rob/Blackfire because while Robin is with Starfire and loves her, the actual sexual activity takes place between him and her older sister. If you're uncomfortable with hardcore lemons, than I suggest skipping chapter 2 which will be out soon. Chapter 3 can function without it.)
It was a typical Friday night at Titans Tower. Beast Boy and Cyborg were Cy's room, playing video games obsessively, Raven was meditating in her room, and Starfire and Robin were sitting by the fire, drinking hot chocolate and enjoying each others company. They had been dating for almost a month, and everything in their relationship was going perfectly. Well, almost perfectly.
"Star?" said Robin softly, feeling her warm body cuddling against him. "What is it, Robin?" she replied, looking up. Robin let out a long breath, and then he did something he had never done before in the presence of another Titan: He removed his mask. Starfire smiled and held her hands to her mouth to stifle a gasp. Robin finally trusted her enough to show her his eyes! They were very dark brown with flecks of white in the irises.
Starfire stopped grinning, however, when she saw the sadness in Robin's eyes. "Star," he said softly, "I've done something, that I'm bitterly ashamed of. Something that I wish I had never done, but I did." "Whatever you have done, Robin," said Starfire, "you can tell me. I love you, and will always forgive you."
At this, Robin's eyes started to gather moisture around the edges, and he said, with his voice on the verge of cracking, "I'm scum. I don't deserve a girlfriend like you." Cupping his face in her hands, Starfire look into Robin's eyes and calmly said, "Tell me what happened, Robin."
Taking a slowly, somewhat halting breath, Robin said, "Okay. Starfire, do you remember last week when your sister, Blackfire, came to visit?" "Yes," she replied, "but what -"
"I slept with her." Robin blurted out. Starfire gave him a confused look, and said, "Robin, I'm afraid that I do not see why you should be so terribly ashamed that you slept in close proximity to my sister. I did the same when I was very young on cold nights." Sighing, Robin said, "On earth, saying that you 'slept' with someone is a euphemism for saying that you and that person . . . engaged in sexual intercourse."
A look of deep pain passed over Starfire's beautiful face as she said, "You and Blackfire . . ." "Yes," said Robin, his voice finally cracking. He turned away from her, as if unworthy to look into her eyes. "I don't know why I did it," he said, starting to tear, "and I wish I could take back what I've done, but I can't."
For a while, both of them were silent, the only noise coming from the crackling of the fireplace. Finally, Star said, in a stoic voice, "Tell me what happened, Robin." "What?" Robin looked up, not quite understanding. "Tell me everything," said Starfire, "You are my boyfriend, and you have betrayed me. I think I am entitled to know EXACTLY what happened between you and my sister." She spoke the last word with a great deal of venom.
Again, they both fell silent. Finally Robin rubbed the back of his neck and said, "It's very hard to talk about." "If you love me," said Starfire darkly, "you will try." "Okay," replied Robin, "here goes."
(A/N: I know this is a little short, but I promise the next chapter (there will only be three) will be longer. BTW, I would like to take this moment to say that I am a devout Rob/Star shipper, and I write the Rob/Blackfire lemon not as an extension of my own beliefs but simply as a means of introducing a rather unlikely ship in an appealing manner.)
