this is good but rewrite below to include the part where Jack also asks - this time firmly - Emily to take off her panties too as he calls her panties not too sexy looking.
Emily feels hesitant as she stands in front of the mirror, wearing the form-fitting black dress that Jack had picked out for her. She looks herself over, feeling the tight fabric hugging her curves all over her body. She watches as Jack admires her, his eyes shining with excitement.

“Jack, I don’t know about this,” Emily says quietly, feeling uneasy about the whole situation. She doesn’t want to risk their relationship just for a night of fun, but she also wants to please Jack.

“Come on, Emily, you look absolutely stunning,” Jack says as he moves closer to her, caressing her bare tits. He gazes down at her breasts with a lustful look in his eyes, and Emily can feel a pang of nervousness as he touches her.

“I’ll just put on a bra, okay?” Emily says as she tries to push his hand away. “I don’t think I can go out like this.”

But Jack just grins at her and shakes his head. “No, no, no. You’ll look amazing without a bra; it’ll be perfect,” he says excitedly.

Emily feels herself relenting, feeling uncomfortable but not wanting to disappoint Jack. As he starts doing her makeup, she looks at herself in the mirror again, feeling like a completely different person. She’s never worn makeup this heavy before, and she can feel it weighing down on her skin.

“I don’t know if I can go through with this,” Emily admits under her breath, feeling more and more uneasy with every passing moment.

But Jack just chuckles and hands her a purse. “Come on, Emily, it’s going to be a night you’ll never forget. You’ll see, it’ll be amazing.”

As they head out the door, Emily still feels reluctant and unsure, but she follows Jack anyway, knowing that she loves him and wants to make him happy.
