Matron is waiting for her class to turn up for their sex education lesson but, as usual, they are phenomenally late. By this stage Matron has given up waiting and she puts her book down and starts to cross & uncross her long legs. She is wearing very sheer natural coloured pantyhose without any panties underneath and as her legs rub together the nylon makes a very sexual noise. The feeling of the nylon rubbing together is making Matron feel very horny and she slowly slips off her tunic, skirt, bra & heels leaving her in just her tights. She runs her hands all over her legs feeling just how soft the nylons are and even stretches them a little over her hands and wriggles her feet inside them. As she sits up on the teacher’s desk she opens her legs, showing her nylon covered pussy and her nylon covered feet resting on the desk. She slowly starts to rubs her pussy; the nylon feels so good against her. As Matron feels more and more exited she rubs her pussy faster until she cannot contain herself any longer and she cums hard right there on the desk in just her pantyhose!
