Solveig challenges me

"You see, the thing with the erection ...." I started to stammer. Ultimately, I couldn't help but explain it to her directly.
"For me it was just not clear if you just sat relaxed in front of your notebook, or if... you know... with the hand between your legs, God knows what you did there."
In my eyes, that was diplomatic enough not to offend anyone.
"So it turns you on, if you watch young girls masturbate?"
"That's not exactly what I wanted to say. What makes you think that I..."
"So you wouldn't care if I put my hand between my legs? Like this? "Her hand slid down her torso and pushed her skirt into her crotch. I wish I could say that I didn't care. But the sight excited me. A lot. I kinda started phantasizing again. But I couldn't just admit that.
"Stop that immediately! What you are doing is not right. You won ... "I called, trying not to look.
"That's right, it's not right," I heard Solveig's voice.
I was relieved and wanted to go home, collecting my tools from the ground. But Solveig had not finished yet.
"No woman I know would please herself just like that. There is too much fabric in between."
"That's not exactly what I wanted to hear..."
She leaned against the copier and watched me put away last tools.
"Oh... come on! You guys get a firm grip of your cock, if you jack off, right?"
"Uh - of course. After all, you want to feel something... "
"I think you might start to understand. But it seems you are more of a visual learning type."
I thought I misheard something. But Solveig proved me wrong already. She was about to unbutton her dress. It gradually opened a hand-wide view of her upper body. The question of the color of her bra was not answered. She wore none. Despite her dress still covering her breasts, what I could guess vrom the view was already inspiring.
Since I obviously lost control of the situation (as if I ever had any control to begin with) I just let things unfold themself now.
Solveig now had only three buttons left to open.
But she kept them closed. Instead, I saw her hand disappear in the dress. I could imagine too well what she was doing there. "Well, I might be a visual learner" I complained. "But you can not see anything about the subject of the lesson!"
"Then maybe you should get a better view yourself..." Solveig did not let my objection interrupt her. With her left hand she began to massage her breasts. So it was probably up to me to open the last three buttons. After initial, but very short hesitation, I unbuttoned the last piece of the dress. This gave me a wonderful view of the action. Because Solveig did not wear any of underwear.
