A/N: This is set in the unbelievably Finchel 'Trial and Error' lemon-verse, but you don't have to read that to get it. PROMPT: Finn finds out Rachel doesn't have a gag reflex.

It's a Saturday night, and Finn's staring at his girlfriend. Although he does this on a regular basis, this was different. He was pretty sure everyone else was staring at her too.

Her fucking fist was in her fucking mouth.

The whole fucking thing.

She pulled it out, grinning. "I just don't have a gag reflex." The entire glee club was in Kurt's basement, watching some dumbass movie. Unfortunately, they'd mentioned putting your fist in your mouth, and they'd all tried. Finn smacked Artie in the back of the head when he opened his mouth, jealously wondering why he had not yet realized the extent of his girlfriend's... skills.

Rachel had helped him overcome his mailman issue - ever since (and before) they'd been fucking like jackrabbits. He just couldn't get the feeling of her walls fluttering around him out of his head.

Now, however, he wanted something else around him. "Rach," he said, his voice coming out a lot deeper than he'd planned, "I forgot something upstairs." The rest of the glee club snickered as Finn and Rachel practically ran away.

"Slut," Finn hissed, pushing her against the wall of the kitchen. She moaned, her head falling back.

"Sorry," she hummed, letting her head lull back as he kissed down her neck.

"You've been holding out on me."

"I'm sorry." He backed away, trading places with her and shoving her lightly to her knees.

"Do you want to suck my cock?" Finn reached down to tug on a nipple.

"Oh god, yes!" Rachel gasped. He unbuttoned his pants, allowing Rachel to pull them and his boxers down to his ankles. She licked down the shaft and Finn buried his hands in her hair.

"Suck it then," he ordered. She nodded and her hot mouth surrounded him. He groaned, hips thrusting involuntarily. He pulled her head forwards slowly, wanting her to take it all. "Breathe through your nose," he crooned, imitating her as she was at Glee club.

She swallowed around him, sucking in her cheeks. He thrust forward again as the area got tighter and tighter. "Fuck." Soon her lips hit his pubes, his cock completely inside her mouth. He began to thrust in and out, fucking her mouth thoroughly. She gasped around him, reaching down to rub her clit. He grabbed her hand and brought it up to his balls instead.

When she began stroking them his thrusts began to lose their rhythm. "Fuck, Rach," he moaned, his body having a mind of its own. "Fuck!" He saw white behind his eyelids as he spurted ropes of cum down her throat. She swallowed, pulling away from him. She gave him one of her large beams, pulling up his pants and buttoning them while he was still in his haze.

"Sorry about that, Rachel," he said, "it was a little harsh." She popped floss and a disposable tooth brush out of her purse.

"I liked it," she said, brushing her teeth and standing on her toes for a kiss.
