As you get ready to walk in you notice she is having another orgasm.......Its only been around 8 minutes of your break so you cannot help but watch and wish that you was the one playing with her pussy instead of stroking your dick......you think to yourself what in the Hell have I gotten myself into......just from a little voyeurism.........so you watch the remaining 2 minutes but forget the time and go over almost 5 minutes before you realize that your late and that your cock is rock hard again...not soft like she asked........damn...
