Pair up with Shannon

You pair up with Shannon without having any idea what to do, and soon enough you find yourself stretching out on the ground together. The two of you stretch out in each other's arms, your faces close together so that she can whisper in your ear:

"This is going to be so fun!"

You stare confusedly at your nerdy friend. Her expression is gleeful, her lips curved upward in a devious grin, and her eyes are bright with mischief and delight.

"Oh come on," she says, her voice light and teasing, "don't tell me you don't want to show off..."

"But I'm not supposed to," you protest weakly. It's true, the rules are very clear on this matter: if you're in gym class, then you should be wearing clothes. And if you aren't wearing clothes, then you're supposed to get detention or something. Right?

"Yeah? Well, maybe we can change that!" Her grin broadens as she looks down at your bulge. "Look, your dick is already showing."

She touches the front of your boxer briefs, where it shows above the waistband of your shorts. There's no mistaking what it is: your semi-hard erection is clearly visible to everyone.
