I was a teachers assistant for the senior girls gym class, during my own senior year. What was involved was my hauling tennis equipment from a large storage area down to the tennis courts at the far side of the school. Then after class returning the rackets and balls back into the storage area. For this work I received half a credit for the trimester. Mrs. Striange was the teacher and I had taken several gym classes as a student of hers in previous years.
What was truly great about being the TA, was watching the girls exercise before they would go outside. Each girl had her own warm up mat. I would sit back in a chair with my back against the wall and watch the stretching exercises. The best was the leg lifts, Mrs. Striange would give the commands, legs up, now apart, now together. When apart some of the girls shorts would gape open giving me short peeps at their crotches. Most of the girls were not even aware of what a view I had of them, at least not the first few days of class. There were 14 girls in the class but two were my favorites, Cynthia and Cheryl, they were a little more shy than the others and had only just turned 18 a few days before the final trimester had started. They both had dark brown chestnut hair and small boobs. Every girl in the class had the same orange colored gym shorts and white T-shirts.
Once they were done with leg lifts I would head out with the equipment to the tennis courts and wait a few minutes for the girls and Mrs. Striange to arrive. The girls would pair up and start playing against each other. It was almost a guarantee that one of the girls would invariably be absent on any given day so then I would have to play opposite one of the girls. Mrs. Striange had been my tennis coach for several years now and told me not to go easy on the girl who I had to play against but not to go all out to humiliate any of them either.
The first week, not one girl ever missed the tennis class. I enjoyed viewing all 14 of them doing their leg lifts, if I was really lucky, I could actually see some curly hairs poking out of their shorts, or one or two might be shaved completely and showing a bit of cunt lips to my eyes.
Watching 13, sometimes 14 sets of bouncing boobs as the girls swatted tennis balls back and forth really got my hormones going into high gear for sure.
The second week, I was watching Cynthia in particular and noticed that she had positioned herself directly in front of my chair where I would be sure to see her most private area. She was still shy and wouldn't look at me but she spread her legs as wide as possible doing the leg lifts and I sure enjoyed the view she offered to me. Her black pubic hair was just a nice small landing strip at the top of her dainty little pussy, the rest had been shaved clean and she had on really baggy white panties that allowed me to see all I wanted.
When Mrs. strange ordered the girls to do 20 jumping jacks, I really enjoyed watching the boobs bounce around as all 14 girls obeyed their teacher. Finished with all but their stretching, I left to go bring the tennis equipment to the courts.
"Roy, I want you to play one on two against Cynthia and Cheryl today and don't hold back, I want to see how well they play as a team?" Mrs. Striange told me.
The girls worked well together and it was difficult for me to return even half the shots, one would work the backcourt while the other was at the net. I had to serve several aces to even stand a chance of tieing up the games we played. In the end they beat me all three games and each one of us were sweaty and tired. Usually I don't need to shower after the girls get finished with the class but today I really needed one. The boys locker room was empty when I went inside so I grabbed a towel and went over to the shower area.
After I had finished showering off and put the wet towel in the bin near the teachers office, I tried the door of the office and was surprised to find it unlocked. I let myself inside and was even more surprised to find a one way mirror that revealed the girls showers. Oh my goodness, most of the 14 girls had finished dressing but Cynthia and Cheryl were still standing underneath the nozzles in the central shower area. Cynthia is about 5'4 and has firm boobs that look to be about a 34b and are even with her armpits. Cheryl is also 5'4 and her boobs were just a shade bigger and a few inches lower. Cheryl had shaved her snatch clean of any hair so her pussy was completely bald, it looked scrumptious with the water dripping down.
I took out my cell phone and took several pictures of them. With water cascading down from their heads, running down their lovely boobs and stomachs then dripping from their pussies onto the shower floor. My cock was as hard as a rock.
Suddenly the door on the girls side of the office started opening. I quickly put my phone into my pocket and realizing I was going to be caught where a student wasn't supposed to be, I froze where I was.
"Roy, what are you doing in here?" Mrs. Striange demanded to know as she closed the office door.
"Well, the door was unlocked and I was curious to see what was inside this office?" I replied timidly.
"You realize I could report you to the vice principle and have you expelled for being in here?" She asked. "I don't want that though, you are too good a student and I need you on our tennis team this year. I will forget you were in here but I want to know which of the girls you saw naked? Don't deny seeing them since your boner gives me proof."
"Umm! I only saw two of them, Cynthia and Cheryl in the showers, the rest had already finished dressing." I answered her question honestly enough.
"Wait right here and I will be back." Mrs. Striange informed me.
A few minutes later she returned with both the girls and asked them to sit down. They were both wearing tight jeans and warm tops as in the springtime sometimes it was still chilly outside.
"Roy managed to get into this office and watched you both in the shower." Mrs. Striange informed the girls. "Ordinarily this would be grounds for immediate expulsion but I don't want to lose our star tennis player, so I have an idea. Since he got to see you both naked, I think it's only fair if you get to see him naked."
Cynthia giggled and smiled at me. "If I had known you were watching I would have given you a show." She told me.
Cheryl seemed a bit embarrassed that
I had seen her naked. "Mrs. Striange I think he needs to be punished for watching us in the shower."
"What do you suggest as a punishment?" Mrs. Striange asked Cheryl.
"Well, until I turned 14 my parents used to give me bare butt spankings for misbehaving. Maybe Cyndi and I could spank him on his bare butt." Cheryl answered.
"That sounds like a fair punishment to me." Mrs. Striange agreed.
"Roy take off your shirt, pants and underwear, you can leave on your socks though." Mrs. Striange ordered me.
My erection had gone down and my penis was limp when I undressed in front of the girls and our teacher.
"Now Roy, lean over this stool and put your hands down on the legs, don't try to stop them from spanking you or I will paddle you myself using one of the tennis rackets and I can promise that you won't like it much at all." Mrs. Striange threatened.
Cheryl went first and her hand stung my butt cheeks as she gave it ten solid spanks with enthusiasm and strength that I didn't realize she had.
Cynthia didn't hit as hard as Cheryl and in fact didn't seem like she even wanted to spank me at all. When she finished with ten light spanks she rubbed both of my butt cheeks and massaged them for a few minutes. The stinging that Cheryl had caused was gone now and my erection was once again at full mast.
"Mrs. Striange is it normal for a guy to get an erection when he gets spanked?" Cheryl asked.
"I don't think it was the spankings but more Cynthia massaging his butt cheeks that caused that reaction." Mrs. Striange answered. "Now Roy get dressed and none of you better even let out one word of what happened in here today."
Out in the hallway heading towards the parking lot, the two girls caught up with me. "Roy we missed our bus, would you mind driving us home?" Cynthia asked.
"Please," Cheryl added in an apologetic tone of voice. "I'm sorry about spanking you earlier but I was a bit upset that you saw us in the shower."
"Both my parents work and if we go to my house first we can talk about today." Cynthia added. I opened the doors on my 10 year old Escape SUV for the girls to get in, Cynthia was up front while Cheryl rode in back.
We drove the few miles over to Cynthia's house and went inside. She offered us some pineapple juice and cookies and we sat on the couch in her parents living room. When we were done with the snack she invited us to her bedroom. She had an office chair that I sat on while they sat on her bed.
"Did the spanking really hurt you?" Cheryl asked me.
