Admirer

As i’ve mentioned a few times i went to boarding school, the school had its own pool and part of the “standard kit list” said boys had to have swimming trunks, these varied from speedos to adidas to arena, all shapes and sizes. Not many would wear them, but u would still get the daring ones who would appear in them, catching the eyes of the girls.
now each house of about 50 of us had a matron who took care of laundry, and each matron had a dispensary where the clothes would be sorted out and put into a pigeon hole for us to collect. Our matron was a busty 50 something, average build, with a son and daughter in their late teens. They had use of the schools facilities which meant to pool.
i clicked on to this fact when i seen a random swimsuit in the back room one day. That night i went for a wee looky, sneaking out in the dead of night into the dispensary i stripped to a little tight blue pair i’d ‘borrowed’ my erection stretching them out. I snuck into the back and looked around, discovering the swimsuit i unfolded it for an explore. It was a black adidas with white stripes. I was so turned on, rubbing it over my body, massaging my hard cock with it. I decided to put it on, my cock standing hard upright, it appeared tighter than i thought it would be.
suddenly i heard footsteps so i quickly hid in the cupboard.
it was matron, turns out she’d heard me (her flat was below) i heard her asking whoever it was to come out, she was getting angry. She said to come out before she got the house master.
my plan was to run when she went to get him. The only problem with that was, she opened the cupboard i was standing in, standing hard, in a tight clingy swimsuit.
she went red with rage, pulling me out the cupboard she started reading me the riot act! I was gonna be expelled! Everybody would know my dirty little secret! Problem was this was turning me on more and more! Especially because her eyes kept darting down to my hard cock. She told me to get out of her daughters swimsuit and get dressed, i of course obeyed. However all i had was my trunks, which i put back on, squeezing my big hard cock into it.
her eyes never strayed from it. I walked over to giver her the swimsuit. Then I seen her sons speedo, she seen me looking at it, picked it up, and then asked if i wanted to wear them because i wasa dirty little pervert. That sent me over the edge, firing my hot sticky load into the trunks, jerking and shaking, shuddering and squirting as she watched wide eyed.
i simply replied with a quiver in my voice “maybe next time” and walked away. Nothing was ever said, but she’d make a point of leaving swimming trunks out after that
