The Ultra-Sexual World Chapter 2: Elementary School
I woke up and yawned. Friday: time for the last day of the school week. I turned to see my naked older sister sleeping next to me. She was 21, making her 4 years older than me. But that didn't make our fuck sessions less amazing. When I was little she always was there to blow me or let me fuck her if I was pent up and couldn't fuck my friends or mom. She woke up and kissed me.
"Morning Matt!"
"Morning Christie!" I replied as I stroked her breasts. She wrapped her arms around me and made out with me. We rolled to where I ended up on top and my cock grew really hard. I was in between her legs now and my cock was resting on the lips of her pussy waiting to go in. She smiled at me. "Time to fuck my awesome sister."
"Time to fuck my awesome brother~" echoed Christie. I entered inside and rapidly fucked her. She moaned and gripped the bed sheets. "Y-you sure have grown down there since you were little~" Even though the species on this world evolved to have fully functional sex parts at a really young age, genitalia and breasts still grew over time. Breasts were fully developed by the age of 10 too but also grew with age.
I blushed at the compliment: "Thanks sis~" I sped up and felt all the walls inside her wrap around my cock and my body was overwhelmed after a couple of minutes and I came. "That was a great fuck."
"Thanks~" said Christie as she got dressed. "Morning fucks are the best."
"Hey aren't you teaching sex ed today?" I asked as I put on my pants. My sister taught at the local elementary school. More specifically she was a 5th grade teacher. While many kids below 5th grade had sex, it was largely small family stuff if anything as they were usually too busy playing with their toys or watching TV to really have a sex drive. Our special evolution made sex drive appear around 5th grade, making 5th grade the year of sex education.
"Yeah! Can't wait!"
"I imagine that'll be the lesson for practically all day." I recounted as I remembered my time in 5th grade.
"Definitely." confirmed Christie, "Especially if we account anatomy lessons and such." We finished getting ready. Christie drove to work and when school began the students walked in and sat down in their assigned seats. A small chatter began like in any school then Christie began writing on the board. SEX EDUCATION was written in red all across as a header for what laid ahead for the students. Several students grinned excitedly while others were curious.
"Morning class!"
"Morning Ms. Hydie!"
"Today is all about sex education." began Christie, "We're going to teach you guys about sex, how to do it, and then have some fun sex for the rest of the day! First we have to go over anatomy." she put up some pictures of male and female genitalia. She went over the names and their function. She then explained what sex was for and why it's important to be willing to fuck others.
"Ok now we're going to go through the forms of sex." said Christie, "But first, we all have to strip naked and get comfy." Many kids took their clothes off and sat back down but a chubby girl was nervous. "Something wrong Amy?"
"I-I'm worried the others won't like my body." said Amy quietly.
"I think your body is fine." said a male student in the back.
"Yeah Amy you're beautiful too!" said a girl. Amy smiled.
"All body types are beautiful Amy." agreed Christie, "Don't be worried or ashamed of how you look. Someone will always want to fuck you." Amy took off her clothes. Christie stripped and sat on the desk and showed her body to everyone. A few guys drooled and even a few ladies blushed. "Now, what's important is to make sure you're pleasing your partner in sex no matter what the activity. So now we're going to learn the different types of activities. I'll need 1 girl volunteer and 1 guy volunteer." Several children raise their hands in excitement.
"Peter and Mary! Come on up!" The two children grin and walk up to Christie. "First we'll need to go over caressing and kissing. Most of you have done this so it should be easy. One should know where their partner is sensitive." Christie caresses Peter's back and uses her other hand to stroke his hardening cock. He moans softly and loosens up his muscles in her arms. "For guys, their back and cock work but they may have special spots they prefer. For females, it's mostly their pussy, sides, and breasts. Peter try on Mary." Peter rubs Mary's sides and breasts. Then he fingers Mary causing a slight moan. Mary returns the favor by rubbing Peter's cock and back.
"Now, as you both relax, usually it's a good time to begin kissing." instructed Christie, "Especially making out. Most of you have probably done this already but in case you haven't, you simply press your lips together and lick each other's tongues. You keep at it only stopping to breathe or to move on to other sexual activities. Go ahead and demonstrate you two." Mary passionately grabs Peter's head and they make out while still stroking each other's genitals. The class is really turned on. As they wrestle their tongues she lectures about oral sex, explaining how it works and the two major types: cunnilingus and fellatio.
"Chris, could you come up here and demonstrate cunnilingus on me please?" asked Christie as she spread her legs. Chris blushed and walked up to her. He got on his knees and licked her pussy's lips. Christie moaned a bit. "N-not bad for your first time~"
"Actually Ms. Hydie I've done it to my sister before." said Chris. He then licked deeper and got Christie to moan louder. Some girls were masturbating in the back of the class by this point. Christie eventually came after a few minutes of bliss. Chris blushed and licked it up.
"Th-that, class, is what happens when a woman orgasms." panted Christie as he stroked Chris' back. "Very good job Chris. Now I'll demonstrate fellatio." Christie had Chris sit on the desk. She got on her knees and licked the tip of his cock. Then after a few tongue strokes up the shaft she sucked on him. Chris moaned loudly and panted.
"M-my sister isn't nearly as good as you Ms. Hydie~" Christie giggles and keeps at it until he cums. He pants and she pulls away.
"That is what a male orgasm looks like~" licked Christie as she removed the cum off of her lips. "Peter? I'll need you and Mary again. Mary please lay down on the desk and spread your legs. Peter, you'll help demonstrate normal fucking. Grab her sides gently to keep her stable on the desk. Then put your hard cock inside her pussy and move back and forth." The two kids stop caressing and do so. Both of them then moan as he speeds up quickly out of excitement. After less than a minute he moans loudly and cums.
"Now, if you don't learn to control your speed, it's harder to last longer." warned Christie, "In addition it's harder to please your female. Of course this is natural. You won't always last 10 minutes and get your partner to orgasm with normal sex even if it may feel good. That's why you combine normal sex with other sexual activities to make it fun and pleasing for everyone!" Peter pulls out and makes out with Mary again then licks her pussy to compensate. Mary moans and after some licking cums.
"Now, normally I'd send you all out to recess but instead we'll be inside and have a fun sex orgy where you all can practice fucking. After that we'll go over anal and lesbian sex." The kids cheer then grab partners. They all practice fucking as moans fill the air along with a sexual aroma that kept everyone turned on. Christie masturbated herself as she watched. She enjoyed her job.
