OK so here's my story.
>Be in after school study, final year of school.
>Total silence apart from occasional rustle of paper.
>Fall asleep on maths book, to tired to study.
>Start dreaming about sexy time with girlfriend.
> Suddenly hear loud moan that wakes me up.
>It was me from dream.
>Everyone including teacher staring at me.
>Really embarrassed and decide to leave.
>Take my books and stand up to go.
> Realize i have raging erection as i walk out of classroom.
