You had safe fun inside her

You lifted her with your thighs and pressed your cock underneath her, pointing at her sex. With your other hand you guided her a little closer to you and slowly let her sink down, the tip of your cock pressing against her entrance between her slick folds.
"Please, don't, we're not protected," she moaned at the sensations, holding herself up while you lowered your thighs further back onto the chair.
"Are you sure, my girl?" you asked while you slipped your tip back and forth between her folds, enticing a longing moan from her. You felt her clench her pussy at 'my girl', then whispered, "You don't sound very sure."
She nodded her as she began to rock her hips back and forth over the tip of your glans in opposite directions. You moaned and clenched you buttocks to press your tip firmer against her. It dipped a little into her entrance when it slid over your tip.
"You're not sure, my girl?" you asked as you tried to still her rocking hips and felt her response to your words.
She nodded moaning and slowed down her rocking until she stopped, breathing heavily between moans.
You moved your hips up and pressed your glans a little into her. She closed her eyes with a loud moan. You briefly held still, then lowered your hips until the tip of your cock pressed only against her entrance. You rubbed the tip along her folds again and she began to rock her hips.

"It looks like you want it, my girl," you said trying to urge her to still her hips.
"Yes, but..." she moaned.
You cut her off, "No buts, my girl."
"It's not safe," she whimpered.
You pressed your glans a little into her, stretching her entrance. "I want to feel your pussy on my cock, my girl, you want me inside you too, right?"
"Yes, ... ehm... no,... but..." she stammered.
"If I promise not to come inside you, is that okay with you, my girl?" you asked as you pressed the rest of your glans into her. She moaned and her pussy tightened in response.
All you could hear was her heavy breathing and see her chest heaving while she seemed to consider it.
You pulled your glans out of her, then whispered, "You want to be my good girl. You want to feel me inside you and you want me to make you mine. I'm right, aren't I, my girl? Tell me!" Then you pushed your glans into her tightness again.

"Ooh!" she moaned as you slipped into her. "I... I..." she paused and you pushed a little further into her, "want you..." then you pulled back, "inside... me."
You held your tip against her folds, rubbing it slowly along her folds. "And what else, my girl?" you insisted. Then slowly pressed the tip inside her. You felt her sinking onto your glans, "Tell me!"
Longingly she moaned, "Make me yours!"

That was all you needed to hear and you thrust deep into her, pressing her shoulders to make her sink onto your cock, "You're mine now, my girl, all mine." She moaned loud and squeezed her hands on your shoulders while her hot velvet canal enveloped your twitching cock tightly. You lifted her with your thighs, then let her sink onto your cock. "Show me how much you want my cock, my girl."
She began to rise and sink onto your cock, moaning loud while you twitched your cock inside her. You felt her tighten and milking your cock whenever she rose and relaxing when she sank down onto your shaft. Her pace increased as did her moans. You lavished in the sensations moaning loud, your cock twitching in delight.

As she began to shudder and her pussy began to spasm on your shaft, you urged her, "Slow down, my girl, don't come!"
She slowed down, but that seemed to bring her only closer to her climax. You thrust deep inside her and warned, "Don't..."
Her body shuddered and she clenched her pelvic muscles on you, begging you, "Please?"
You thrust deep into her again, "Please what?"
"Please, may I come?" she begged.
Another deep thrust made her shudder even more, "Tell me you're mine."
Her shudders alternated with shakes as her climax seemed only seconds away. "I'm yours, John," she moaned longingly.
"Good girl, my good girl," you mused as you pulled your cock as far back as your hips managed under her bouncing pussy.
Then you thrust deep into her, as far as you could manage. Your cock began to throb inside her. "Come, now, my girl," you moaned.
"Yes!" she cried out, while you felt her pelvic muscles tighten for a moment while her body began to shake and her hips jerked. You tried to hold your cock inside her, bouncing your hips with hers. Then her pussy spasmed around you cock and the shakes of her body increased making her moans loud and ragged as her climax washed over her. Your cock throbbed hard inside her and it took great effort from you to hold back your own climax.
As her body's shakes lessened, you urged her, "Up!"
She lifted herself with trembling legs and you pulled your cock out of her, then pressed her down while aiming your glans towards her breasts. Your cock pulsed and throbbed, ready to shoot your load.
"I'm marking you as mine with my seed, my girl," you managed to utter, while you grabbed your shaft. She was still shaking and moaning while her climax began to subside.
It took only a few strokes, then you moaned alternated with groans while you watched your cock squirting the first jets of cum against her breasts. "Mine," you growled as more jets splattered against her torso.
She nodded eagerly at your words in the haze of her climax, while you splattered the last drops onto her belly.

Slowly you both stilled. You smiled at her then watched with a grin how your seed trickled over her skin.
"Thank you," she whispered.
You grinned at her, "My pleasure, my girl."
You moved a finger over her lower belly upwards to scoop up some of your cum. The sensations made her moan soft. You brought your finger to her lips. "Taste my cum," you ordered as you began to smear it over her lips.
She lapped at your finger, then licked her lips.
"Clean it," you urged and she sucked your cum off your finger, causing a stirring in your cock.
You smiled while you watched her sucking your finger, "You like it, don't you? Now clean my cock, my girl."

She nodded and climbed off your lap with unsteady and trembling legs, then sunk to her knees between your legs as you parted them. She looked up at you. "Go on," you said, then she wrapped her lips around your limp cock. She took the full length inside her mouth, swirling her tongue over your shaft and while she slowly moved her mouth back, her tongue swirled and teased your glans. You moaned loud at the sensations and caressed the back of her head.

"Very good, my girl," you said as she lifted her lips from your cock. She looked up smiling and you nodded, "Yes, very good."
"Thank you," she whispered holding herself steady with her hands on your thighs.
You smiled at her, then nodded towards the hall, "Go clean yourself up, there is a bathroom down the hall."
She nodded and got onto her feet. The sight of your cum trickling down all the way into her pubes made you smile happily. Her legs were still unsteady as she paddled to the bathroom.

You sat back and drank some water, before putting your clothes back on. You picked up her panties and stashed them into the pocket of your jeans, letting a tiny piece stick out.
"Get dressed, my girl," you said as she returned.
She looked around then at you. "Where are my panties?" she asked.
You pointed at the part of her panties sticking out of your pocket, "You're going to have to earn them back next time."
She grinned and nodded, "Hmmmm, I'd like that."
She put her clothes on and you admired the somewhat reversed stripping. You walked over to the bookshelves and scribbled your name and phone number on a piece of paper, then handed it to her.
"In case you want your panties back before my next lecture," you said with a wink, "Let me bring you home."
She smiled, taking the piece of paper, "Thank you," then headed into the living room to gather her stuff.

You drove to her home. "You were great, my girl, do you always come like that?" asking her along the way.
She shook her head, "Ehm... No, I never came so... hard before."
"But you liked it, right?"
She nodded eagerly, "Oh god, yes. It was amazing, John!"
"Good," you said as you stopped at her front door. You leaned towards her and took her chin turning her face towards you. You kissed her lips tenderly then looked into her eyes. "Enjoy the afterglow of coming for me," you said.
"Thank you, John," she said smiling happily.
"Good night, my girl," you said as you leaned further and opened the passenger door.
She got out and leaned into the car, "Good night, John."
You watched her as she went inside, then drove off.
