On a 10+, Luna does it willingly, +1 forward

You catch Luna's attention during a scene change and whisper your proposition. She giggles and nods. "As long as you're still wearing them. That was the deal," she says.

You raise the armrest between the seats.

"This is a boring part. Kiss me first," she whispers.

Luna is a good kisser. Her lips are soft, her breath is sweet under the popcorn taste, and her tongue is clever and active. You hear her breath change, becoming deeper and faster through her nose. A hint of a moan vibrates as she breathes out.

The music changes and the soundtrack swells with cheers and the rumble of roller skates. Luna pulls back.

"Okay they're skating again," she says. "Get ready."

You hurriedly pull your shorts up tight so you can fish your cock out of the leg hole, pulling aside Luna's, Jennifer's, and Tara's panties. It's tight on one side, but you can move your knees and you can tuck yourself away quickly if you have to. Luna whips up the back of her tennis skirt and eagerly sits down in your lap. The first try, she misses, bending your cock to the side.

"Oops sorry!" she half-whispers.

With a little care, you thread the needle, finding Luna's vaginal entrance between a pair of wet, swollen inner lips. Luna sighs as she takes you in, ending with a little "uuuhh!?" as she realizes how big and long your cock is.

Luna is sitting on your cock, and it feels heavenly. This was already a good day, with Karen, and Luna makes it a banner day. She squeezes you with her pussy a couple times to say hello, then relaxes back into you.

"Ow!" you say as Luna puts her weight on your bruise.

"Ssh!" comes a complaint from the next row.

"Huh?" Luna says.

"Sorry, got a bruise on my chest," you whisper.

"Ooh," Luna says. She sits up straight, then gives your cock a couple of pussy squeezes. How lovely.

You can't see the cute roller girls in the movie with Luna's head and shoulders in front of you, but you don't care. Luna may come off as a space cadet, but she's very real and very present, her weight in your lap, her hot, wet pussy squeezing your cock. You bring your arms around to gently hold her big, naturally bra-free breasts, wishing you could grab her and pull her back tightly. She sighs, giggling under her breath as you nibble on her ear.

You remember one of the advanced techniques from the Pickup Artists' Guide -- no, actually, this one was from the Goofy Foot Guide to Sex -- and squeeze down on your PC muscle, making your cock swell inside her. This little conversation goes back and forth for a while, Luna squeezing your shaft, then you squeezing down to swell and pulse inside her. You can't really move very much here in the theater seats. You're getting hot and hard and feeling like you'd love to bend Luna over the back of the seat and pound her, but you don't think you could get away with anything more obvious than your already risky move.

Luna's clearly a game girl. Maybe there's some quiet corner you could find to pound down the home stretch together?

Meanwhile, Luna is shifting her hips, changing the balance of her weight and grinding herself on the base of of your cock. Her pussy squeezes are getting more erratic, less deliberate. She might just come and leave you hanging. Not the worst fate, but oh, how frustrating. Your cock swells inside her. Maybe this is going to work, maybe...
