She locks you in for the rest of the movie

Okay, you had a deal, now that she had her orgasm she has to let you go, right?

"lmmmph mrffff glph!" you try to tell her to let you go, but even though her dick is now half softened, it's still too fat to speak intelligibly around. Her attention snaps from the movie to you, and she gives you a look like she forgot you were even down here with her dick in your face. You see her look of mild surprise change to a mischievous smirk, and involuntarily gulp.

"Hmmm should I let you go now Dougy?" she said, putting on an exaggerated thinking face while keeping your mouth on her penis, still gradually leaking precum onto your tongue. "We had a deal... but you tried to spit my dick out early! I had to leglock you just to get you to hold up your end!" she said with mock anger. "I think it's only fair that you make it up to my cock for the rest of the movie <3" she says with a wink.

You feel her start to lift her legs off of your shoulders. For a moment you have a glimmer of hope, hoping that she's taking pity on you and letting you out, but then she grabs your head with her hand and pulls you back down to the base. With her schlong only semi-hard now, and thoroughly lubed up with her cum, it slides down your throat with relative ease, settling comfortably with your lips kissing her balls and her stomach. While you try your best not to gag on her dick, you hear a ruffling and a metallic sound above you. Suddenly you feel the leather of her belt against the back of your head! Before you can piece together what's happening, she pulls the belt tight around you, pressing you firmly into her pelvis, just barely managing to secure the belt clasp and lock you in.

*CLACK*

"Ahhhhhh~" she sighs in relief, sitting back and relaxing with a satisfied smile as she looks down into your teary eyes. "Now I can relax and just enjoy the movie without worrying about you trying to get out of swallowing my salami!" Right on cue, you feel her 'salami' stiffening, getting thicker and stretching your throat more. As she gets harder you can actually feel it lengthen, the bulge in your throat extending further down toward your stomach. You try looking up at her with pleading eyes.

"Awww you look so cute looking up at me with those blowjob eyes!" Tiffany gushes. "Hold up, I have to show this to my friends!" She takes her phone and starts recording you! She holds her phone up above her, capturing a selfie video with both herself, and you below her, lips secured around her base. You try again to get her cock out of your mouth, or at least get yourself out of the way, but her belt has you locked in super tightly, and all you succeed in doing is stimulating her dick some more and giving her some material for her video. After a minute she makes a cute face, and heart with her fingers, before ending it and sending it to the other girls in your class.

She then goes back to ignoring you, returning her attention to the movie. Her belt doesn't even allow enough movement for any thrusting, but it doesn't seem to bother her. She's content to just soak her cock in your throat, getting all the stimulation she needs from your gag reflex. At least now without her legs around your ears you can hear the movie and --- yep, time for another sex scene. The futa heroine of the movie is interrogating the male henchman, so of course she's facefucking him to get him to talk. You roll your eyes at how contrived it is. Looking down at you, Tiffany giggles. "Yeahhh I guess it's a little silly, I mean how does she expect him to tell her where his boss is while she's balls deep in his face?" She stares at you for a second and laughs to herself. "Though... I guess we're not really in a position to criticise them huh?" she teases, flexing her cock in your throat to make her point.

It occurs to you that she's really treating this like a normal date -- the selfie, the playful banter, everything about it feels just like a cute date, except for the part where she's basically wearing your face like a pair of pants, belt keeping you secured to the hilt. Your train of thought is interrupted as the movie scene comes to a climax. As you can hear the futa in the movie approach her orgasm, you can feel Tiffany's cock start throbbing harder in your mouth, and her balls start to push up to your chin. "Mmm fuck Doug, cliché or not this scene is reaaaaaally getting me going... I hope you're ready for dessert!" Perfectly synced with the movie, she reaches her climax, and you can feel her balls squeezing another load out. You feel her girlcock pulse in your throat, feeding you another load of her sperm. You can't help but gag while she throbs and flexes in your throat, unintentionally milking her balls for every drop.

Coming down from her orgasm, she looks down at you with a loving smile. "Thanks babe," she says, caressing your cheek a bit as her dong softens a little, though it's still more than long enough to stay deep in your throat. "Y'know Doug, I'm really enjoying our date. I kinda want to untie you now as a reward, buuuuut," she pauses and bites her lip, "unfortunately my cock is kinda falling for you too~". She gives it a little flex. "and the two of you look so cute together! Let's just stay like this for the rest of the movie <3". She gets a bit more comfortable, scooting back a bit in her seat, bringing your head with her.

Your "date" continues like this for the rest of the movie. She keeps casually chatting with you now and then, though the only responses you're capable of are gagging on her dick. Tiffany has an impressive amount of stamina, and feeds you another 3 loads, her belt keeping her schlong secured in your throat the entire time. After her fifth and final orgasm, your stomach feels completely full of her cum, and you hear the credits rolling. She stretches and looks down at you.
