Watch a movie

"Would you like to watch a movie, honey?"

You've got nothing better to do so you say yes. Your aunt dims the lights and sits down next to you. She's wearing her pajamas which consist of a tight t-shirt and some pants. Your heart starts to beat a little faster. She puts a film on the streaming service and settles in.

"My friend recommended this movie. She says it's really good."

The movie is pretty good. It's about a detective trying to solve a ****, and things predictably get more complicated, with double cross after double cross. The femme fatale role is played by gorgeous redhead, and you're transfixed every time she is on the screen. You look over at your aunt, who is staring at the screen. The soft glow of the television illuminates her face. She really is beautiful. Suddenly she breathes sharply and looks over at you. You quickly look at the screen, blushing a little.

You realise why your aunt gasped. The redhead has undone her dress and is showing her breasts. She is seducing the detective, and he's falling for it. All of a sudden everything you've been trying to repress over the last few days rushes to the surface. Your cock stiffens and tries to get hard but your cage stops it, and it hurts. The redhead pushes the detective back onto the bed and mounts him, slowly grinding and gyrating on him. It's softcore but it is enough to make you whimper as your cock is pinched by the plastic cage. You look over at your aunt who is looking at you with a concerned expression.

"Honey, are you ok?"

You grimace and nod. You notice that your aunts nipples are visible through her tight t-shirt, and your cock throbs harder. The scene only lasts for a few minutes but every second is agony. Finally the detective and redhead moan in unison and the scene is over. The rest of the movie plays out but you can no longer focus on it. You can only focus on the feeling of your cock throbbing and leaking into your briefs.
