Pending title: frustrated bisexual writes fanfic about frustrated bisexual as means of coping

Cassian is fucking ridiculous.
He's been fantasizing about this moment for months, and now that it's happening, he can't move.
Jyn Erso is half naked in his bunk, flushed and panting and kriffing hell he wantsher, but he can't move.
Confusion, then worry, taints the desire in her eyes as she sits up.
"What's wrong?" she breathes, and he wants to kick himself for ruining the moment.
"Nothing," he says quickly, "nothing I just…" he meets her eyes and forces himself to say it, "I've never been with a woman before."
She blinks at him, the tension in her shoulders easing.
"You're a virgin?"
The blood leaves his face in a violent rush.
"No! No, I'm not a virgin I've just… never been with a woman."
Why are the words so difficult to find? He's been attracted to both sexes for as long as he can remember. He's never been ashamed of it before, he still isn't, so why is he struggling to tell her?
Jyn raises a coy eyebrow, "Do you not know where to put it?"
The look on his face must be utterly priceless, because her smile gives way to an eruption of laughter. Cassian sits back on his heels.
"You're making fun of me." he says, a little incredulous.
"No, love." she says, still laughing, reaching for his hand, "I'm not."
He shoots her a look.
"Okay, maybe a little bit." she pulls his hand into her lap, running her thumbs across his palm, "Cassian, did you think I would mind? You liking men?"
He sighs and shifts a little closer, "No. I know you're not that kind of person."
She smiles softly and brings his hand to her lips. The anxieties ease out of his body as she burrows herself into his side, hugging him tightly.
He can hear the smile in her voice, "You really don't know where to put it, do you?"
He shoves her to the other side of the bunk, another laugh knocked out of her when she hits the pillows. He crawls over her, hunger returning tenfold.
"I know where to put it." he growls, bending to run his mouth across her jaw.
She grins, "Prove it."
