You interrupt her to spice things up

“Ah, Mrs. North! Wait a moment!”

While Mrs. North had still been talking, I noticed that my classmates had gotten aroused watching us. That, plus the fact that I wanted my friends to have some fun from the beginning, made me interrupt Mrs. North here.

“Your teaching is effective, I have no doubt about that. But don't you think that for the titjob, we should simply make girl-boy pairs and you guide us through the process? That way, we can practice immediately.“

Mrs. North thought for a second and then replied.

“I guess you have a point. Everyone, get together in pairs, just like Daniel said.“

I simply watched as my classmates talked among themselves like normal, trying to find a suitable partner for everyone. Since I could have any one of the girls whenever I wanted, I decided to let fate take the wheel and see which girl would be left over for me. A few minutes passed and then, an energetic voice called my name.

“Well, seems like I'll be your partner, Daniel!“

I looked up and smiled

“Fine by me, Alice.“

I probably couldn't have gotten a better partner for this lesson than Alice. Not because she was extremely hot or very experienced, but because she does whatever she has to do with a smile and lots of energy. She just likes to give it her all, no matter what the situation might be. I've been friends with her for a while now as well, and her energy always helps when things get rough.

That's not to dismiss her body, though. Yeah, she is a bit smaller than most of my other female classmates, but her breasts are probably the most well-build out of all of them. Her hair has a nice, soft red hue and flows just a bit over her shoulders. Her face, always beaming with happiness, is perfect too. So yeah, I really can't complain about it.

“Has everyone found a partner?“

Mrs. North disrupts my thoughts and I look around. It seems like indeed, everyone is now sitting in a pair next to each other. Alice hurries over to my side as well.

“Alright then. Since I don't have a partner to demonstrate titjobs with, I'll be using this broom here. Now, Let's begin.“

Mrs. North leaned the broom against the black board and started to unbutton her shirt. Within seconds, her boobs were jiggling outside of her shirt, naked for all to see.

“Since you will be using your breasts, all girls can prepare like I just did. We don't have that much time left, so try to take of as few pieces of clothing as possible while still having your breasts properly exposed. The boys can take out their penises as well.“

Everyone did as they were told. The girls pulled up their shirts and bras and exposed their breasts while the boys let their penis hang outside of their pants. Alice, seemingly excited about the new experience, was almost to hyped to take out her boobs.

“Oh, this is so exiting! I've never done anything with my tits before!“

That sentence intrigued me, so I pressed her further

“Oh? Does that mean you did other stuff?“

“Of course! I already gave lots of blowjobs, but Mrs. North is on another level! I've never seen that kind of technique before!“

“Seems like she was really impressed by Mrs. North's sexual wisdom from earlier, huh“ I thought.

Then, Mrs. North continued, the broom back in her hand.

„Now“, she said, moving the broom to match her actions, „As the name suggests, A titjob is performed by mimicking the movements of intercourse with your breasts. Instead of taking the penis in your mouth like I showed you earlier, you have to slide it up and down between your breasts, like this.“

The girls watched Mrs. North move her tits up and down the handle of the broom for a few moments before facing their respective partner. They tried positioning themselves correctly and soon, the entire classroom was filled with lewd sounds and moans.

“Alright, that looks fun!“

Alice practically radiated excitement and immediately started imitating Mrs. North's movements on my dick. Her breasts were so soft I had to concentrate not to cum on the spot, and it seems like having cum only minutes earlier from Mrs. North's blowjob helped a bit. I look down at Alice, happily bobbing her tits up and down on my penis.

“This is so much fun! It feels hot and hard! Hey, Daniel! Is it good like this?“

“Yeah, that feels great! But...“

“Now.“ Before I could finish my sentence, Mrs. North raised her voice once more. “After you have gotten comfortable with your movement, you will notice that the tip of the penis will be within the reach of your mouth. Licking and sucking that, thus adding a blowjob on top, is liked among many men, so practice that as well.“

Finishing her explanation, Mrs. North dove down to the head of the broom and started licking it furiously. Her tongue went in circles around it, interjected by her mouth swallowing and letting go of it occasionally.

“I wanna try that, too!“

Before I could say anything, I felt something warm and slippery around the tip of my dick. Unable to hold back, I let our a loud grunt and looked down. Alice was still bouncing up and down, my penis firmly pressed between her tits. But now, her mouth was also sucking on the tip in a way that I had never thought possible.

“She wasn't lying when she said she gave blowjobs before“ was the last thing I could think before her tongue touched my dick, pushing me over the edge. I unloaded inside of her mouth almost more than earlier inside of Mrs. North's mouth, briefly thinking that it would never stop. Even while I was cumming, Alice still kept going, determined to milk me completely dry. Amidst my pleasure, I could faintly hear the other pairs finishing up as well.

A few minutes later, all of us were sitting in our chairs, exhausted from the lesson. Alice was the only one seemingly unfazed by any of her actions, simply smiling and asking:

“That was so much fun! Can we do that again?“

Before I could give her any kind of reply, the bell rang.

*Ding-Dong-Dang-Dong*

“Well, that's the end of today's biology lesson. Be sure to review everything we covered seriously. This WILL be on the test, understood?“

Mrs. North had already returned to her usual appearance, with her breasts tucked away and completely clean. All of us started cleaning ourselves up as well and one after the other left the classroom.

“Seems like we have no time for another round, huh?“

Alice threw me a look of pure disappointment. I grinned and said.

“Oh don't worry! Just don't go home after school today, but wait for me instead. Then I can take you back home with me and you'll just do whatever I want with you from then on, OK?"

Alice's face light up.

“Really? You'd do that for me? Thanks so much! Oh, I can't wait!“

Almost like she was dancing, Alice walked away, humming in pure bliss.

“Now then“ I thought, „Where to next“?
