Tease her, then Seolhyun plots

You crouch down beside her and look into her eyes. "Always look that beautiful when you climax," you smirk. You reach out and gently stroke her flushed cheek.

"I think I'm going to enjoy this job," she replies, smiling brightly.

"Why don't you go and get cleaned up," you tell her. "There's a shower, third door on the left."

"Okay!" Ahin says, smiling widely. “Thank you again!” She leaves the room, and you and Seolhyun are alone.

You get back into your chair, still breathing heavily, your heavy erection nodding up and down. Seolhyun, for her part, stands behind you and starts unbuttoning your shirt. "I think Ahin did very well," she muses. "But I'm not done with you yet."

"Didn't expect you to be," you reply.

She strokes your chest with one hand while the other slowly encircles your cock. Soon, she's stroking you as you relax.

"We should plan my next movie," Seolhyun says. "Does this feel good, by the way?"

"Mm..." you manage in response, her soft palm pressing against your throbbing hot shaft.

"I'm glad," Seolhyun smiles. "Now, what do you think would be a good scenario for my second video?"

You look down at Seolhyun's diligent fingers as they work your stiff cock. You consider her question, then say, "How about... you and Ahin as sisters?"

"Really? That's pretty bold," Seolhyun says, licking her lips. "I imagine you'd want me to play her big sister who seduces her, no?"

"Well, that certainly could be... stimulating," you say.

"Do you have a younger sister, John?" Seolhyun asks.

"No, why?" you reply.

"Because I don't think you'd be into something like that if you had a younger sister," she says.

"So you're not into it?" you ask.

"Oh, I didn't say that," she says. "I'm just more interested in what gets you off." At this she pinches your nipple and speeds up the languorous pace of her handjob. You grunt with arousal in response, and Seolhyun giggles. "I want to be a great pornstar," she says.

"You are," you reply. "You are. I'm not sure about the sister thing now... how about we do a teacher-student roleplay instead? You can be the hot young teacher who tries to seduce her student."

"Mmmm, Ahin in a schoolgirl outfit, huh?" Seolhyun says, "I'm picturing it and I like it... are you picturing it, John?"

You moan as she speeds up her hand, and Seolhyun giggles once more.

"I'll take that as a yes," she says. "You gonna cum for me?"

"You… tell… me," you say, breathing harder.

"I'm asking you," Seolhyun smiles.

"Then yes," you pant, "I'm gonna... ahhh!"

Seolhyun has no problem whatsoever finishing your sentence, hissing “Cum!” into your ear as she speeds up to an extremely quick pace, and that's all it takes to send you over the edge. You grab the hand on your chest to steady yourself as you erupt, sending rope after rope of thick, gooey white seed onto your desk, your thighs and her hand. She continues to gently milk you of every drop as you sigh in ecstasy.

"That was so much," Seolhyun giggles, "It's all over your desk. I guess you liked it huh?"

"You have no idea," you say, finally catching your breath.

"Well, I'd better be going," she says, heading for the door. "You might want to clean up your desk before you start writing the script, you know," she adds, matter-of-factly, as if she wasn't the cause of the spray of jizz all over it.

"Yeah, I should,” you reply, “See you tomorrow, Seol."

Seolhyun grins and waves as she shuts the door behind her. You stare thoughtfully at it for a moment, gather your thoughts, then head off to the shower. When you're done, you wipe down your desk and get to work on the script for Ahin and Seolhyun's first adult movie together.
