My Girlfriend's Mother Has a Secret

"So, do you make my little girl do this" asked Julie.

Tim was unable to answer because his mouth was full off cock; he just looked up and nodded his head gently. She continued to slowly move her hips back and forth, pumping her cock into Tim's unresisting mouth. After a few minutes Julie gripped Tim's head, and began to fuck her cock into Tim's mouth faster and deeper.

"Use your tongue, push against it as I push in, think about how you like it done, slut boy."

Fuck this was good she thought, his first cock. She'd always fantasised about doing this to a straight guy, somebody who'd never had a cock fucked into his mouth. For a first time cock sucker he wasn't too bad, but he needs to be trained, she thought, but there would be time for that later.

She continued to fuck Tim's mouth, sometimes pulling back and make short rapid thrust between his lips, and then making deeper and longer thrusts. She tried to think of unsexy thoughts in an effort to hold off, but Julie was too excited and horny to hold back much longer. She gripped hi head firmly and forced her cock in hard, and with a loud groan she began to pump her spunk into Tim's mouth. He tried to pull away, his hand coming up to try and pull hers away, but her grip was too firm, and she continued to fuck his mouth hard and deep. A little of the sperm squirted out of the side of his mouth, and despite himself, he began to swallow. Part of him wanted to gag as he felt the thick warm gooeyness slipping down his throat and yet strangely he was also excited about it.

Julie pumped her cock back and forth, her legs shacking, until with a sigh, she pulled out, and released her grip around Tim's head. He fell back onto back his ankles with a gasp. He lifted his hand up and whipped the spunk that had seeped from his mouth from his face.

Meanwhile Julie had collapsed unto her bed and just lay there for a while. Christ, she thought, it had been a while since she had blow job like that. After a few minutes had past, she lifted herself up and looked down at Tim, and was pleasantly surprised to see, that not only a smile, but that his cock was almost fully erect.
