The sex lesson

"I'll tell you when we get there" she said, her voice sounding strange.
My curiousity was building as we reached the classroom. As she led me in I noticed that it must have been the sex ed class as the room was full of the 30 odd senior girls. Ms Summers closed the door behind her and locked it. My cock started to twitch at the thought of what might be happening.

"Ok class..." she said "I have a special lesson today and I want you all to pay very close attention"
"As you know from our last class we were discussing boys and in particular how their bodies work. I have chosen Jaime to help us out for today because I know from talking with you all that you find him the most attractive of the senior boys"
All of this was coming as quite a shock to me, but by now my cock was so hard I was just trying to cover it up with my hands.
"We were going to watch a movie today but I thought a live demonstration would be a lot more fun" Ms Summers explained.
All the girls started getting excited and I could hear them whispering and giggling amongst themselves. I was almost cumming in my pants by now.

"Come over here Jaime" Ms Summers cooed, as she tapped on her desk. "Now I want you all to see what a real boys cock looks like, so gather around"
Ms Summers then grabbed the front of my pants and started to unbutton them. I was so horny and in no way going to refuse.
She then slowly started unzipping my fly. I undid my shirt and took it off. The girls were biting their bottom lips in anticipation. I sat on the edge of the desk as Ms Summers deftly removed my shorts and threw them in the corner. By now I was only wearing my jockeys and my erection was clear to see. Ms Summers then kneeled in front of me and grabbed my jockeys from the sides, and slowly pulled them down. My cock then sprang free as if it was escaping from a prison. It was throbbing and as stiff as it had ever been, pointing straight at the roof. There I was, naked in plain view of all these beautiful girls and sexy teacher. The girls were staring at it as Ms Summers placed her hand on my cock and ran her thumb over the head, spreading my pre-cum all over the tip.
"I love your big cock" Ms Summers said as she played with it. "I want you girls to feel it. Feel how hard and warm it is"
The girls then took turns fondling my cock and feeling my throbbing member. I was about to cum right then until Ms Summers told them to stop. "Now that cock looks ready to blow and we don't want to lose all that tasty cum" Ms Summers purred.
"Now I want to show you girls how to give a guy a blowjob but I'll need a volunteer"

One of Naomi's friends Jenna said she wanted to lick it. Of Naomi's friends she was the hottest, and I'd always secretly wanted to fuck her.
"Ok Jenna" Ms Summers said "but first I'll show you how"
Ms Summers then started to lick up the length of my shaft, then sucking my cock deep down her throat. She would stop sucking and then flick the tip with her tongue. This was too much and I shot streams of cum out of my cock that had so much force they flew over Ms Summers head and onto the girls watching. She then said "Ok Jenna, make sure you lick all that cum off his dick" and Jenna took her place. Jenna then started to suck my cock and while not as good as Ms Summers blowjob, was still making me hard again in no time. The other girls were sampling the jism I had just shot all over them and looked like they wished they had volunteered instead of Jenna. A few of them were getting naked too and fingering themselves as they watched my cock being sucked.

When my cock was as hard as it was before Ms Summers said "Ok Jenna that'll do. I now want to show you girls how to fuck" and she started removing her blouse. As she unsnapped her bra her sensational tits bounced out. My god they were fucking awesome. Round and perky. Not too big and not too small, and her nipples were as hard as two little pebbles. I started to rub her hard nipples between my thumb and index fingers as she moaned "ooooooo yeessss baby lick them" I didn't need to be told twice and started flicking my tongue over them. She liked it when I pulled at them gently between my teeth and pulled my cock with her hand. She then backed up and looked into my eyes while she undid her skirt and let it drop to the ground. She told me to get on my knees and take off her panties with my mouth. As I did my nose brushed past her neatly trimmed blonde haired pussy and I could smell her sweet and musky scent. I threw her panties away and placed my hands on the inside of her thighs and pressed them apart, giving me a full view of her glorious pussy. I ran my tongue up and down her slit, tasting her juices. The folds of her pussy were moist and her clit was very sensitive. As I flicked over her clit with my tongue she would arch her back clamp my head between her thighs. I continued exploring her pussy with my tongue and probing her hole. "Lick that pussy. suck it hard. stick your tongue inside me baby" she purred.

I continued to lick her pussy until she said "Get up baby. I want you to fuck me now. I want that hard cock in my pussy" and she went over to the chairs and grabbed one of them. She put it down so that the back of it was facing the side of the room, and raised her left leg onto it. She cooed "Fuck me like a dog. Stick that big hard cock in my pussy baby" and she spread her pussy lips with her fingers between her legs.

All the girls had a close up view as I stood behind her and guided my cock to her pussy. I rubbed my cock up and down her slit and slapped her pussy with it to tease her. She moaned "Stick it in. Fuck me now. I wanna feel your big hard cock inside me."
I slid it in and moaned with pleasure as her pussy gripped my cock. "Oooo baby fuck me. fuck me hard!" she moaned as I picked up the pace. Her pussy felt so good I didn't want to stop. After several minutes we had a good rhythm going and we were both moaning loudly.
" ooooooo yeahhh that feels so good" I yelled "I'm gonna cum" and I pulled my cock out of her pussy. She turned around and sucked my cock as it spurted cum all down her throat and in her mouth. I came so much it was dripping out of her mouth as she sucked me dry. "Oooo baby did that feel good" she asked.
"O hell yeah" I replied in earnest. "That was the greatest fucking moment of my life."

A week later Ms Summers was gone. But she did change the girls minds about sex that's for sure. I am now seeing Jenna, Naomi's friend, and we have sex all the time. I have Ms Summers to thank for that!
