She moaned and groaned as he pushed it in. Her legs quivered beneath her, her hands gripping the sheets as tight as they could. She could feel it - her stomach ever-so-slightly bulging as it went further and further in. As it finally reached as far as it could go, she went cross-eyed and couldn't stop the moaning grunts. Her whole body shook at the feeling. Shook from the feeling of him being inside of him... and perhaps fear for when he starts thrusting.

On the outside, they're just a cute couple. The stereotypical popular college girl with her nerdy boyfriend. She got with him because of his personality. She didn't expect much in terms of the bedroom. She never could have expected... this.

For his cock to be the size of her forearm, and perhaps even as wide as well. It's the type of cock that you can fell physically fill you up. The kind that takes your breath away as it reaches its deepest depths - and only continues to do so with each thrust. The kind that's so large it borders on hurting... but instead sits at that sweet spot of making her cum until she's overstimulated.

He's able to have a full-blown conversation while he thrusts with minimal grunts - meanwhile she's nearly going dumb on his cock from the sheer size of it. She thought herself to be a rather "needy" girl sex-wise, but now she's the one who can't keep up with his libido. Every time she's sleeping with him, she feels a hint of fear when she sees him with a boner or when he's getting particularly flirty with her because she knows she likely won't be able to walk very well the next day.

So let's play out this dynamic. The popular girl who gets in over her head with a nerdy guy who has the biggest cock she's ever seen. One... that she can hardly handle ;). Also open to pairings other than boyfriend/girlfriend.

[M4F] Your nerdy boyfriend's cock is so big it almost hurts.
