From behind

Laurie pulled her lips away from Dan, and turned her face away, looking back out across the city. "We shouldn't be doing this" she whispered.

Even as she spoke, she felt Dan continuing to move his hands over her body, slipping into her tights. Even quieter before, she sighed "Dan... this is wrong".

She felt his fingers pushing into her panties, and Dan began to kiss her neck. She closed her eyes, as his finger tips ran down, brushing against her bush. 'I should tell him to stop' she said to herself, but her nothing left her mouth. She felt the first shot of pleasure as Dan began to stroke and rub her pussy, quickly finding her clit. She let out a little gasp, and felt his fingers pushing down further, sliding against her hot, wet cunt.

Laurie leant forwards, her head over the wall, bending at her hip. Dan slid his other hand up her thigh, pushed up her skirt, squeezed her ass, then began to pull down her tights. She heard the fabric ladder as he tugged it them down over her hips, and felt the cool air against her ass as they reached her thighs. Dan grabbed her panties and pulled them aside at the crotch, exposing her pussy to the night. She moaned softly as one hand rubbed her clit, while Dan's other fingers entered her from behind. Instinctively, she began to move with Dan as he fingered her, arching her back and pushing against him.

Then Dan stopped. She looked over her shoulder, and saw him unbuttoning his trousers. She bit her lips as she watched him pull out cock. It was as long and fat as she had remembered, and now fully erect, the bulging head gleaming with precum. Laurie felt a strange cocktail of emotions run through her: Shame - that she was drunk on a roof, bent over and cheating; Lust - her body longed for Dan to fill her; and Fear. She had never taken a cock of that size, and couldn't imagine how it would stretch her. The shame and fear welled up:

"Wait!"

Dan placed one hand on her hip. With the other, he ran his cock up from her pussy, along her ass crack, resting it against the small of her back. It felt surprisingly heavy, and Laurie couldn't contemplate how far inside her it would reach.

"You need this Bunny. I know you want it"

Lust began to build again, but Laurie spoke:

"This is wrong, Alex would be so hurt..."

"You've always been a good girl Laurie. Don't you want to have some fun before you graduate?"

He ran his cock down, brushing the tip against the lips of her pussy.

"Everyone does this. He's never going to find out."

"I..."

Laurie felt her body twitch. All her life she had done what she was meant to.

"You have to live a little."

'Do I want to have a boring life? Shouldn't I make some memories ?'

She closed her eyes. "You gotta use a condom"

"I don't have one". Dan's voice was calm, patient. He put his hands on her hips, his cock against her, waiting.

Laurie hesitated. Time slowed down. She had always made Alex use a condom. She remembered the precum she had seen leaking from Dan's cock. But the lust had spread up from her crotch to fill every part of her with a warm glow.

"Oh... well, just promise to pull out..."

Behind her, Dan smiled, and without speaking slowly began drive his cock into her pussy.
