Start rough

Jake undoes his fly and pulls out his semi hard cock. From Audrey's point of view, with the mirror she can't see much besides her own reflection and Jake from the waist up. He slowly strokes his cock with one hand while groping Audrey's ass through her shorts the the other.

"Okay let's get these out of the way." Jake says as he reaches around Audrey's waist with both hands and starts to unbutton them. She shuffles herself to bring her legs together so her shorts can be lowered. As Jake finishes undoing her fly he yanks down her shorts down to her knees and looks at her ass.

Jake reaches down with a hand and pulls her panties to the side to reveal her slit. Jake wastes no time with bringing his cock up in line to penetrate Audrey. He presses his cock head against her entrance which results in her tensing with anticipation.

"Well let's see what you can do." Audrey laughs looking in the mirror at Jake. She still hasn't seen his cock which beats the vibrator in length and girth.

"Oh fuck, you're not going to last a minute." Jake scoffs as he holds his cock in position and grabs her shoulder for leverage with her other hand.

"We'll see about that I doubt I'll even fe-" Audrey starts but is cut off as Jake rams his cock into Audrey using her shoulder to pull her back onto him.

He can immediately feel how tight she is around him which is a pleasant surprise being that he expected her to be loose. Everyone on the football team at least had thought that she would of been with a body like hers and that she must of had taken a shit ton of cocks.

But nonetheless Jake pushes until he gets about 2/3rds of his cock into her which is where he can't push any further. He holds it there as Audrey's eyes and mouth open wide. Her back arcs further as Jake plunges into her.

"Oh fuck you're tight!" Jake moans throwing his head back and smiling.

"Fuuuuck! Take it out! It's too big!" Audrey screams as she gets stretched from behind. Jake smiles knowing that he destroyed her expectations for his size. He places his now free hand on her hip with his other still on her shoulder.

He pulls back his hips slowly until just the head is in. Audrey, who is still screaming, relaxing slightly as he does. Although just like before her uses his leverage on her to slam most of his length back into her, which is rewarded with another scream from her.
