"Oh god! Yes!" Katie yelled instantly. "Oh my god, put your dick in me!" Tim gave a few small thrusts, fucking her with the tip. He was enjoying teasing her but more than that, he wanted to enjoy fucking her. He slowly pushed the entire length of his shaft into her wet and wanting cunt, bottoming out and holding there, his body straining to get deeper, a long low moan escaping from Katie. Tim glanced down, surveying the sight before him and let out a small laugh of disbelief. He was literally balls deep inside one of his students that he'd been fantasizing about for the last year.
"Fuck, Katie. I can't believe I'm inside you. Goddamn you feel good." Katie's hands were still on her breasts, pinching and pulling at her nipples. She stared up at him.
"Well now that you're inside of me, are you gonna fuck me or what?" Oh so that's how she wanted it? Well, Tim could and would give it to her. His grip on her knees eased and moved to her hips as he began to pull back and thrust into her, slow and hard. Each time his hips met her body he watched the impact ripple through her. He began to pick up speed, his abs and ass flexing with the effort and force. In no time he was really fucking her, the sound of his balls slapping and Katie moaning filling his small office. Tim was panting by now but didn't let up, in fact he started shoving his dick inside of her as hard and fast as he could.
"How's that, huh? You fucking like that? My fat cock filling you up?" Tim could feel the sheen of sweat that was beginning to cover his body. "Yeah, take that cock, baby, take it!" Tim watched as Katie's body took the pounding he was giving her; her arms up over her head and gripping the edge of the desk, her tits bouncing wildly, her eyes clenched shut and her mouth wide in a breathless gasp. He was amazed he was still going strong, but he was. He bent over Katie, bringing his arms to rest on either side of her hot body. His mouth hovered over hers, both of them gasping. "You feel that? I'm getting close, Katie. I'm getting so close. I'm gonna dump my cum inside your tight little hole. That's what you wanted, right? Answer me! Tell me how much you want this hot load in you!"
"Yes, Coach! Fucking fill me up with your cum! I wanna feel you shooting inside me." Tim felt taken over by his desire for her and somehow began to pound even faster. His head was against the desk, his chest pressed against her tits while he humped away at Katie's pussy with fervor.
"Shit I'm gonna cum! Oh fuck, fuck!" Tim's balls contracted as they pushed a second load up into his shaft. It burst out the tip of his dick, buried deep inside of Katie's cunt, and began to fill her. "Oh god, I'm fucking cumming in you. Fuuuuck. Uhhhh." Tim continued slamming into Katie, his cock contracting as shot after shot burst into her pussy. His second time cumming didn't last as long as the first and he began to slow his hips, finishing with a hard and prolonged thrust to really fuck the cum as deep as possible. They both lay still as their breathing returned to normal.
Tim pushed himself up and began to pull his dick out. He was already soft, spent. The second his shaft was out, his load followed. Katie smiled and laughed. "See, I told you you could cum again! Maybe next time we'll go for three!"
