Your best friend, Jenny

Jenny had been a long time friend and neighbour of yours growing up and the two of you were pretty close. Still, it was a bit of a surprise when she walked straight up to you out of everyone. She was athletic and slim, a bit taller than you and with long straw blond hair which she usually wore up.

"Hey are you sure you want to pick me?" you ask, it would be a shame if this made your friendship kind of awkward.

"No, but's it a hell of a lot of a better choice than any of these drooling perverts, at least I know you aren't going to spend the rest of the day staring at my ass after this"

You ponder on the many days out with Jenny you'd spent sneaking glimpses at her behind over the years. "Absolutely!" you say in response.

Once every settles down the music starts. A couple of the younger female staff members are at the front of the room, looking over the girls and occasionally commenting or giving advice. Jenny starts to sway her hips in time with the song, she seems nervous but after a little bit you see a slight smile emerge on her face. After that she throws herself into it, grinding herself into your lap and pushing her chest out into your face (there isn't much there, but it's the thought that counts).

Then she starts stripping off, first revealing her small, perky, breasts is a black lacy bra, and then throwing that aside as well. "I know there are probably girls you'd rather have seen," she says, gesturing to her chest "but I'm grateful you paired with me and I think I can make it up to you"

With that she turns around and removes her skirt, pulling it all the way down to her feet till she's touching her toes. Jenny had always been sporty (way more than you anyway) and time spent on the track or in the gym had given her a large, well shaped and firm butt which had occupied your fantasies since you hit puberty.

And now she was shaking it in front of your face.

Best. Lucky find. Ever.

You hear a whistle blown by one of the teachers "ok everyone, stop where you are, now we need to move on to the oral sex portion of the lesson"

With that the entire row of girls drops to their knees at once. You fumble for a bit but manage to undo your fly and pull your, by this point, rock-hard dick out for Jenny to see.

"Huh" she says

"What's 'huh'?"

Before she can answer the whistle blows again and Jenny needs her mouth for other things. She's definitely never done this before but one of the TA's, a young redhead called Sarah, kneels down next to her and talks her through some of the basic steps. Pretty soon Jenny is bobbing her head up and down in your lap at a good pace, keeping a pleasant suction. She get's told her eye contact needs work though, not that you're complaining.

Then the teachers get everyone's attention again; "everyone finish up and then start getting ready for you next class"

Jenny removes her mouth from your cock but keeps on stroking it with one hand. "Are you close?"

You can only nod your head through gritted teeth.

"Good... Would you judge me if I said I had enjoyed this?" she says giving you a wink and a cheesy grin. Then she gives you one final long lick the entire length of your twitching shaft.

That sight is what finally pushes you over the edge, your childhood friend is now kneeling at your feet with your cum all over her hair and face.

"Guess I need to go get cleaned up, see you in history"

With that Jenny bundles up her clothes and walks away, you could swear you can see her putting a bit more sway in her hips than usual though.

You also fix yourself, while it's unlikely to be as good as that you do still have to get on with the rest of your day.
