Cum in her bottle (femdom)

I watched her as she left the room. I was dumbstruck as she left the room, this was the first time I was able to see her in such a compromising light. Sure, her husband flaunted her off to me but this time I was able to see most of her body, something I thought would never happen. My dick was rock solid and it was straining against my pants.

It was so uncomfortable and in my horny mind I figured out it would take a few minutes for her to return so I reasoned that it was possible to be able to masturbate before she came back to reinforce that image of her into my brain. I whipped my dick out and started to pump my hand up and down, trying to bring myself to an orgasm as quickly as possible.

Maybe it was the sight of my tutor in such a compromising situation or it was that I was jacking off in such a public place and that possibly she could she that I quickly reached my orgasm. I looked around the room for any tissues to cum into but there was nothing. Getting close to cumming, I got **** and grabbed my tutor's bottle that she always drank from during class.

I opened the bottle with one hand and positioned my cock over the neck of the bottle into it. I groaned quietly as my cum shot into the bottle. I heard hurried footsteps up the stair case and I rushed to cap the bottle and place it back into its place. Lacking time, I pushed my chair forward so that my penis was hidden underneath the table.

She entered the room, red-faced obviously for rushing around to get her clothes on and come back. I slowly admired her appearance with my new understanding of myself. She had an almost business woman like appearance to her as she had a pencil skirt on that highlighted her ass, a dress shirt that was slightly rumpled and not fully tucked into to her skirt because she rushed to put it on.

"I'm so sorry about the wait. Today's been so hectic," She tried to explain.

I stuttered back guilty, "It's okay miss, everyone has off days."

We continued with the lesson, it was awkward for me because my dick was hanging out and it was difficult to maneuver my dick back into my pants because it was so big, so I just left it hoping she would turn around or leave the room again.

As the lesson progressed, to my horror she grabbed her bottle to drink from it. As she removed the cap, I saw that there was some cum still around the lip of the bottle. She didn't notice because she was still explaining something and she put her lips to the part that had the cum on it. She drank from it with a huge gulp. With the sight in front my dick got uncomfortably hard, pressing against the table.

With a bit disgust, she held the bottle from her and remarked, "What in the world? That was salty, it reminds me of something..."

I started to sweat slightly at that but to my relief she explained it away with, "I mustn't have filled it up since yesterday," but still with narrowed eyes on it. She returned back to teaching but something must've changed because she looked at me with a suspicious glint. Almost on purpose she knocked her pen of her table and went to grab it. Before I could say anything she looked underneath the table and surely saw my dick.
