New story - skimpy speedo at school

[Schoolspeedo]

The young female teacher answered the door and recognised me' "ah yes, I think you forgot your little swim briefs, not much fabric in them." she went to fetch it and held it up outstretched, looking at it, "I'm surprised it covers anything at all" and winked, handing it to me. "I got it from a friend", I replied a bit embarrassed. "It's cute. I don't have a problem with it as that style seems to be coming into fashion. Certainly women's bikinis are getting tiny and thongs and g-strings are very common in French beaches. I know as I have a couple of them that I wear topless", she smiled. My heart was racing and my groin started to ache with a stiffening of my cock, as I imagined her in a tiny thong, with her amazing breasts jutting out and swaying when she walked.
"is that all", she asked and jolted me from my thought, "um..er..yes miss", I blurted and left the office.
With that thought still in my mind, I went to the games field and changed into my kit for playing rugby; my tight little swim brief again covering my package.
After a game in very muddy conditions, I returned to the changing room and peeled everything off to join the other guys in the communal plunge pool bath.

Back at the boarding house, I sought out my French friend, who had given me the ridiculously brief bikini."how did you get on with your new swim brief?", he asked smiling.
I told him about my experience and he smiled. "let me see it on you. I'm going up for a shower anyway so good chance to let me see it", he said and we made our way up to the communal shower room, where he stopped off. I wriggled into the tiny brief, though with my cock starting to get semi, with this strange encounter. He was naked and I could see how well hung he was, with quite a long thick, veiny shaft and circumsised, quite bulbous head. he saw me looking and said,' this is why I can't really wear that minuscule brief, even though my aunt keeps buying them for me" and he bounced his cock with his hand.
