You took her to your office

She entered the lecture hall at exactly 5pm. You looked up from your papers hearing the door close and smiled, "Ah, Lisa, nice that you're punctual. Let's go to my office."
She nodded and watched you as you walked up to her from behind the desk. Her eyes went down to your jeans and as they moved up she secretly admired your body.
"It's just down the hall," you said as you walked up the steps towards the exit, "follow me."
She followed you quietly into your office and sat down in the chair opposite your desk as you closed the door.

"How much of the lecture did you actually get?" you asked while sitting down on the desk directly in front of her.
She looked down and sighed, "Not much," she admitted, "A bit of the start and end."
"So basically nothing," you said while frowning, "You're not going to pass my course if you don't pay attention. Do you even remember what today's topic was?"
She nodded, "Yes, it was about the psychophysical reactions to hugs given in different kind of relationships."
"Right," you stood up and towered over her, "so what would happen if we were to hug?" You moved your hand indicating she should stand up.
"Ehm..." she started as she got up. Her heart started to beat faster as she stood almost touching you. "A release of endorphins?"
"Correct," you wrapped your arms around her and pulled her against you. "Hug me back and tell me how it makes you feel."

She stiffened at first then relaxed as she wrapped her arms around you. Her heartbeat increased a little again. "Ehm..." she started, uncertain about how to describe the initial feeling. "It feels kind of good, I guess."
You shook your head, "Give in to the sensations, make the hug yours. Don't be shy." You held her even tighter and she slowly snuggled against you in your hug. "Yes, like that, Lisa," you said while your member stiffened in your pants against her.
She hesitated for a moment from the sensations against her lower belly then snuggled more against you wrapping her arms a little tighter around you. Uncertain she asked while looking into your eyes, "Like this?"
"Not exactly," you said while moving your hands down over her back and cupped her buttocks. You gave them a squeeze and pulled her tighter against you. "More like this," and you thrust your groin against her lower belly.

She drew in a sharp breath and nodded slowly. She moved her hands onto your buttocks and pulled you against her. Hesitantly she asked, "Are you sure this isn't inappropriate?"
You shook your head, "Not at all, it's simply a practical example of the theories I outline in my lectures. Tell me how you feel, Lisa?" You gyrated your hips against her, letting out a barely audible longing sigh.
She sought for words, swallowed, then replied, "Ehm... really good."
"Go on, it's more than that," you insisted.
A blush reddened her cheeks and she took a deep breath, "A little arousing, I guess."
You withdrew your hands and groin and pulled yourself out of the hug. You examined her face, "That feels good, doesn't it? Better than with your boyfriend or husband, I think."
She nodded, "Yes, it does." She paused briefly, "I... don't have a boyfriend at the moment. I want to focus on my study."
"Good. Now that's the effect of the release of endorphins, and it can get even better," you said with a smile and placed your hand on her shoulder while looking into her eyes. "How many boyfriends did you have?"
She blushed, "Only one," and looked to the ground.

You lifted her chin with your hand, forcing her to look at your face, "Only one? Why?"
Reluctantly she looked at you, swallowed hard, "I almost got pregnant and... ehm... never had a boyfriend since."
You shrugged, "That doesn't sound like a reason not to have a boyfriend," and insisted, "So what else?"
"I... I'm allergic to lots of things. The pill makes me nauseous and latex gives me a rash," she mumbled with reddened cheeks.
He nodded slowly, "You can have relatively safe sex in other ways. And..." You smiled and gently squeezed her shoulder, "You certainly don't need a boyfriend for that. Look at how the hug made you feel. It's better than it was with your boyfriend, I bet."
She nodded slowly, "Yes, I guess you're right. But still... I don't want to be considered a slut."
