If you’re a young good-looking guy, fresh out of training college, teaching classes full of teenagers, you should probably expect the occasional crush. If the girl makes it clear she’s definitely up for it, could you really blame him?

I’ve been substitute teaching in the area for eight months now but this is my first time at this particular high school.

I graduated from teaching college a year ago but haven’t found a permanent position as yet. I quite like acting as a sub, I get to meet a lot of kids and see what the local schools are like.

I’m taking over from the form teacher, a Ms Withers, who has unexpectedly called in sick. The mixed class of fifteen-year-olds I’m sitting in front of is also my first class of the day: English.

I take the roll call and each pupil in turn raises their hand. I try to remember each child’s name but some don’t stick. One that does is a strikingly pretty girl called Phoebe.

I’m walking around the room having an open discussion about the book they’ve been assigned, when I see Phoebe passing a note to a girl across from her.

I walk to that aisle, take it from her hand, and then go back to my desk and read it.

“What do you think?”

“Lovely, I’m all wet!”

“Me too!!”

I hope I don’t come across as too vain when I say that this wouldn’t be the first teenage crush I’d had to deal with. I’m pretty good-looking, if I say so myself, and I keep in good shape.

It’s actually quite sweet in a way but I know that if I let this slide they’ll start taking advantage of me. Best to set the right tone early on.

“Go to the headmaster’s study and tell him what you’ve done,” I tell her. “Tell him I recommend two nights detention.” There’s an audible gasp around the room. Was that too severe, I think? Oh well, it’s too late now.

It turns out that Ms Withers was also scheduled to take detention today so I end up doing that too. There are two older boys as well as Phoebe and I tell them to read quietly.

We’re about half an hour in and Phoebe is jiggling and fidgeting and it’s obvious she needs to go to the loo.

Eventually, she puts her hand up I wave her toward the door.

“Off you go, don’t take all day,” I tell her.

When she comes back and sits down, as she crosses her legs, I can clearly see that she now has no panties on. In the brief glimpse that I get, I see that her pussy is either bald or very nearly so.

I can’t help but start to get aroused and find my eyes drawn back to her legs every time she so much as twitches them.

Twice more I see that gorgeous little pussy and by that time I’m fully erect and grateful for the baggy chinos that I’m wearing which show very little.

As she leaves she gives me a little nervous smile and I wish her and the other lads a good remainder of the day.

It’s still a beautiful afternoon and I decide to go to the small town beach and lie in the sun for a bit before getting on with the prep for the next day’s lessons.

It’s not a novel idea and the beach is almost packed. I find a space a couple of rows back from the ocean and lay out my towel.

After a quick swim, I lie back on my towel and prepare to soak up the rays. After about ten minutes a shadow passes over me and, when I open my eyes, I can see up a skirt and catch a glimpse of a delightful pair of white panties barely covering a lovely little ass. The girl takes the only other available spot, directly in front of me and in the next row down but one.

I sit up, resting on my elbows, and watch as she takes off her T-shirt and skirt to show a lovely small white bikini. As she arranges her towel on the sand I see her face and it’s Phoebe. That’s the second time today she’s made me hard and I’m really starting to like this girl a lot.

As she gets her stuff together she bends down several times and the view I get of her ass is superb, as is the ass itself.

My erection is getting a bit serious and I turn over onto my front and dig a hole in the sand for it to sit in.

I have to lean up on my elbows to see over the girl in the row between us. and I continue to watch Phoebe in what I hope is a not-too-obvious way.

She applies suntan lotion all over, and seems to concentrate to a suspicious degree on her breasts and ass. It’s lovely to watch and I wriggle around occasionally to partially satisfy the desperate urge I have to thrust at something with my cock.

Before she lies down she notices me and gives me that sexy little shy smile of hers. I grin back and then she lies down on her front.

I recognize the way she rotates her hips on the sand as the same action as my own, and I suspect she may be getting aroused as well.

She keeps turning over and casting little smiles in my direction before lying back down. When getting comfortable again she inevitably opens her legs and I get amazing views of her pussy tightly encased in her bikini bottoms.

My cock is really hard now and I have to keep raising my ass up to relieve the pressure on it.

After an hour or so the sun is getting quite low and, looking around, I see that a lot of people have given up for the day. I look back and Phoebe parts her legs again, I can see that the gusset of her bikini bottoms is noticeably wet and I find myself licking my lips and trying to imagine how it would taste.

A little later Phoebe packs up her gear and walks past me towards the changing booths, giving me another cute smile as she passes.

I get up and follow her into the booth, shutting the door behind me.
