My hot teacher saw my boner at a waterslide [MF]

So when i was in college there was a teacher that wore a loose shirt everyday and whenever she bent over i could see her bra straps, the full bra and even her tits i think i saw her nipple once, but one day there was a event at my school where you went on a water slide and stuff( it was at the end of the year, so like celebrating and stuff) and this hot teacher went with all the scared students to the top of the water slide, i pretended to be scared and i went with her, while we went up the stairs she was in a sort of white shorts and black t shirt and her shorts were see through and i could see her ass and panties, and her ass wasn’t just ones and stuff it was like 3/4 of a phat ass and i was getting a boner right behind her, i really just wanted to jack off behind her and cum on her ass but there were people behind us, and when we reached to the top i had to go the front (lightest at the from heaviest at the back) and i forgot i had a boner and i walked up to the raft and sat down, but while i was walking to the front i looked at my teacher and she was just staring at me and i didn’t realise she was looking at my boner until a couple of weeks later, and when i sat down at the front it was sort of like a lay down position and of course that ment my dick was pointing up and when we were going down the ride my teachers shirt went up because of all the water and air, and when i looked back, she had a bikini top on and her tits weren’t tiny they were like c cup size, and i just kept looking for like 2 seconds before she pulled her shirt back down and I couldn’t stop thinking about her tits, and when we got to the bottom, i jumped out and when i went underwater my teacher was still in the raft and her ass was just sitting in the hole i could see her ass and i stayed as long as i could underwater jacking off to her ass, but then and then we she was getting out she fell into the hole in more and her ass hanging even lower and i swam right up to it, but when i looked closer there was some cum coming out of her pussy not a lot but a little bit, and i didn’t want her to feel my dick so i just put my dick above her pussy and poked her ass with my dick and her head was still above water so she couldn’t see me but i when i was about to pop up, i went up as fast i could cause i couldn’t hold my breathe for the long and my dick accidentally kept touching her leg like from her calf to her ass and when i popped back up i looked at her but she didn’t look back and i think she didn’t want to make it awkward. message me if you want to see a pic of her.
