I had gone home that day, addicted to the sureal time shared with Erica. I was craving more. I couldn't think of anything else. I felt like a junkie needing to score. I masturbated three times that night just trying to quench my desire. It was a very restless night. I was up early and found myself primping in the mirror. What the hell was I doing. This was just a student of mine. One that by all teaching standards, that I shouldn't be messing around with. Today we were going on location to several areas to observe only what life guards do in different scenarios are what they are faced with. Our first stop was a local pool. I awaited the students there. I was anticipating Erica's arrival. Everyone showed up including Erica. I instructed everyone to sit and take notes. They were allowed one hour and could go anywhere on the premises. At the end of all our visits, they were to submit a paper that was kind of like their final exam. Several times during that hour, students were approaching me with comments and observations. This left me no time to slip off with Erica as I was hoping. The secret sneak away seemed so forbidden and wrong, the thrill of sneaking off had me flustered with excitement. The hour was up and we were to meet in the parking lot of a local beach. As we were leaving the pool Erica walked up and stuffed something in my pocket secretly. I got into my car, and like a kid at Christmas opening their present, I reached into my pocket. There was a skimpy pair of satin panties. I immediately began sniffing them. I was lost in the pool of scents that the panties beared. Resisting masturbation was overbearing. I was shaking with anticipation. We arrived at the beach. They students were on their way without instruction. I was in a tower of sorts overlooking the beach. It was sort of like a crows nest on a ship, short solid wall in which I looked over to observe. I was scouring the beach looking for Erica. It was like playing a real life Where's Waldo game. Suddenly there she was. Right next to me in the tower! Erica teased me knowing I wanted to fuck her senseless. Finally she dropped her shorts and grabbed her ankles. Her ass was pointing to the sun. Her pink pussy was protruding from under her tight little butt cheeks. I wasted no time and slid my monster into her awaiting tunnel. As I was looking all around, trying not to be obvious we bumped our bodies in the hot sun. I watched as people would walk under the tower pointing up with speculation in their eyes. My heart was pounding every moment. Several times I thought we had gotten caught. I could feel Erica's hand as she played with her clit. I could hear her moans getting louder. I was trying to whisper to her, "Shhh" "You are getting too loud,Shhhhh!" Suddenly She gushed all down her legs. She was squirting like Niagara Falls. Both her hands grabbed the walls,pushing her wet snatch deep onto my hungry penis. I let out a loud "Ahhh!" and quickly silenced myself as I blew a hot load of semen deep inside of Erica's dripping pussy. I quickly looked around to see if anyone had heard me. I must have had luck on my side that day. Not a soul in sight. She quickly used her towel to wipe up, as she left me standing in a puddle of juices. The following morning I was to had out the completion certificates to each of the students. I was so proud of each and every one of my students. It was an honor to serve them with this certificate. Afterwards we had a small get together amongst us. Erica approached me with a cute oriental girl. "This is my partner,Mia" she said. We smiled our last goodbyes with a look of thanks in our eyes. This was a year I will fantasize about often.
