Simon's training

"Eyes on the road, Simon," said Emily from the back seat.

I looked away from the rear view mirror just in time to keep from drifting off the edge of the road. Still, it felt like it might have been worth it to keep looking. Sally was back in her plastic container, and Adam was in 'normal mode', so he and Emily were making out in the back seat. He'd just started pulling her tank top over her head when she'd told me to stop looking. I'd barely gotten a glance at her big breasts in her black bra, and I desperately wanted to see more.

However, my duty was clear. Emily wanted me to drive us home, and I would do that safely. The giggling and the sucking sounds from the back seat weren't going to distract me. No matter how much I wanted to see her incredible body or stare at her beautiful face, serving her needs was more important than my wants.

I was still hard as hell, though.

"Yeah, Adam, suck my titties! Just like that, un huh, yeah! I'm going to ride your big cock so hard when we get home!"

"We're here," I said as I pulled up outside of Emily's house. I desperately wanted to look back at the couple as they continued making out, but Emily had told me not to. I listened intently as they finished up. Even the sound of Emily's top sliding back on, the soft fabric sliding across her perfect skin, was incredibly erotic.

"Adam, take Sally inside," said Emily. "Then strip, handcuff yourself to the bed so you're lying facedown, and wait for me."

"Yes, Emily," said the musclebound ex-jock with the most lovesick voice.

Once he was gone, Emily got out of the car and got in the passenger seat next to me. My body temp rose as she leaned over and breathed heavily on my neck. She reached down, unzipped my pants, and pulled out my cock.

I just kept my eyes on the road, breathing hard.

"This isn't bad," said Emily. "However, the rest of you needs some work. So here's what you're going to do."

A week later, I woke up and immediately started my morning routine by going to Jenny's room and knocking on her door. "Unh, I'm awake, I'm awake," said my step-sister through the door.

"Can I come in?"

"You don't have to ask, Simon. You know you always have permission to come in my room."

I opened the door and walked in. She was lying on her bed, the sheets kicked off. She usually gets too hot at night in the summer, so she always kicks the sheets off. She was lying there wearing nothing but an oversized football jersey and tiny yellow panties.

Before I could even ask, Jenny said, "Just go ahead and do it, Simon. We've done this every morning, I know the routine by now."

Most of the time Jenny is very playful in the way she teases me, but right when she wakes up she's a lot more blunt. I ignored her annoyed tone and pulled off her panties. Despite her initial complaints about my "pervy" new morning routine, she always relaxed as I did it.

I licked her inner thigh, giving her a chance to relax and get used to me, just like she'd taught me. After a few licks I was at her outer lips. She breathed deeply and put her delicate hand on my head.

"Faster," said Jenny.

I licked faster. She didn't usually ask for this so soon. Was putting her hand on my head a hint about what she wanted? I'd ask her once I was done. Right now I needed to focus on using the flat of my tongue in the right spot.

Jenny got worked up faster than any other day we'd done this. I took her heavy breathing as a sign that she wanted me to move things along, so I focused on her clit. Jenny arched her back as she came, forcing me to lift my head up to continue licking her.

When she'd regained her strength, Jenny said, "Not so quick next time, bro. A lady likes to take her time."

"Oh really? You were panting like a steam engine. I figured I'd better finish you off before you overheated."

Jenny sat up, her thick, red hair falling in front of one eye, and punched me in the shoulder. "Just because a girl's body is reacting strongly doesn't mean she wants it to be over with as soon as possible, doofus!"

She spent the next few minutes explaining to me how to tease a girl to make things last longer, and how it's good to take your time even when the girl seems eager. She wasn't too enthusiastic about giving me this lesson, but I'd told her several days ago to always thoroughly explain how I could improve.

I paid close attention, but it was tough. I was hornier than I'd ever been in my life. Looking at my step-sister sitting cross legged on her bed, nearly naked, I couldn't help but think about how much I wished I could be in bed with Emily right now. I hadn't seen her in a week, and I wasn't allowed to jerk off, so the sexual pressure had been building and building.

Luckily, Emily had given me a way to release that tension. I changed my clothes and headed to the gym. I waved to the gym bros as I entered. After a week I was beginning to get to know some of them, and they were really helpful. They were extremely impressed with how much I'd learned about weightlifting technique in such a short time and how intensely I hit my workouts.

For the next two hours, I channeled every bit of my sexual frustration into lifting weights. My muscles were on fire, but I kept going. Jerry, one of the gym bros, asked me how I could maintain that much intensity in the second hour. I told him that I had a lady I was trying to look good for, and he understood immediately.

Once I was done, I showered, then grabbed a protein shake to drink on the way home. When I got home I cooked a bunch of eggs for more protein and sliced up some tomatoes to balance out my nutrition. I was exhausted, but the websites I'd read said that you have to feed those hungry muscles right after a workout. As soon as I was finished with breakfast I took another nap.

Most of my day went normally. I couldn't help glancing out the window at Emily's house regularly, so I noticed Adam pulling into her driveway around 3pm. Lucky guy. I took a run for my afternoon cardio training.

Around 9pm I got a text message from Iris.

"hey. don member who u r, but yur in my phone as 'booty call'. come over"

I hopped in my car and headed for the university. The address she sent me turned out to be a sorority house. I found a place to park, then approached and knocked on the door.

A short girl with heavily bleached hair answered. She looked me up and down, not seeming terribly impressed, then plastered on a big, fake smile. "Hi there! Can I help you?"

"Yes, I'm here to see Iris."

She looked me over again, as if surprised, then turned around and yelled, "Iris! There's a guy here who says he wants to see you!"

I waited uncomfortably at the front door as the blonde girl stared at me with a smile that didn't cover up her judgement of me. She clearly didn't expect her sorority sister to know me. Finally Iris walked into the front room. She looked at me and said, "Oh yeah, I remember now. You're the guy from that thing with Dr. Green." Then she grabbed my hand and pulled me past the blonde girl. "C'mon, let's go to my room."

I assume the girl had a shocked look on her face, but Iris yanked me past her so quickly that I couldn't tell. I don't know how such a small girl could be so strong, but I nearly tripped over myself as she dragged me up the stairs. She didn't slow down once we got into her room. As soon as the door was closed, she pulled her t-shirt over her head and tossed it aside.

I watched as she undressed. Her tight jeans came off next, showing off large hips that flared out from her narrow waist. Then her bra and panties came off, revealing the rest of her sweet body. Every bit of her was manicured, the only hair on her was her long, silky black hair and her perfectly trimmed eyebrows.

I paid special attention to her breasts. They were definitely bigger than they were a week ago. A C-cup now, maybe more? Not as big as Jenny's and nowhere near as big as Lauren's new breasts, but definitely nice. They were perky, and most importantly they didn't have any hint of stretch marks.

"Uh," said Iris, "aren't you going to take off your clothes, too?"

"Oh, yeah, right." I unbuttoned my shirt, but kept looking at her. "Hey, have your breasts gotten bigger since last week?"

"Yeah, actually!" she brightened up as she said this. "I used to be the flattest girl in my family, but I suddenly had a growth spurt! I went bra shopping yesterday. See how cute this is?!" She picked up her discarded bra and held it against her breasts. It was pink with little black bows.

"Yeah, that's super cute," I said. I finished taking off my clothes while she went to her dresser and pulled out a condom. She handed it to me as soon as I had finished undressing and I put it on.

Iris laid back on the bed. Her long, black hair splayed out underneath her, and her full breasts flattened out as she laid on her back. This would have been the most erotic thing I'd ever seen a couple of weeks ago. Now, I let my eyes go into soft focus so I could pretend that she was Emily. I crawled into the bed and climbed on top of her.

I kissed her passionately. She wasn't the woman I wanted to be with, but I hadn't had any sexual release in a week and my body was moving on automatic. I pushed my cock into her tight pussy after just a few seconds of frantic kissing, and I started moving as fast as I could right away.

"Slow down!" said Iris. "I'm not a fucking body pillow that you just hump away at!"

"Sorry!" I said, slowing down. I couldn't think. My body wanted to ram into this small girl as hard as possible, but I had to do a good job. I wasn't here for myself, I was here to get better at this for Emily. My gorgeous Emily.

"Mmm, that's better," said Iris. She wrapped her arms around my neck and smiled, eyes closed in bliss. Then she opened her eyes and looked at me. "Your face... are you about to cum already?!"

"I think... I think so, yes!"

"Stop it!" she yelled, slapping my shoulder. "Don't cum until I do!"

I stopped moving entirely. That was the only way I could last.

After a moment of heavy breathing had stretched out way too long, Iris said, "Don't just lie on top of me. If you can't fuck, do something for me."

I didn't know what else to do, so I leaned down and kissed her slender neck. She liked that, but then she put her hand on my shoulder and pushed me down. She guided me to her breasts, which wasn't quite far enough down to make me pull all the way out of her pussy. With my tip still inserted in her, I sucked one of her round nipples into my mouth. This honestly wasn't much less stimulation than actual sex, a fat titty in my mouth and a tight pussy squeezing my cockhead were still plenty of mental and physical stimulation, and the way she clenched up when I sucked her nipple felt great on my cock. I tried hard not to think about Emily.

Finally I got control of myself again and pushed back inside the girl. I managed to fuck her for another minute before it was too much and I had to slow down again. So I sucked on her other nipple. We went back and forth like this for awhile.

"I'm getting close," Iris finally said. "Yes, right there! Faster! Yes, go, go gooooo!"

Her body tensed up under me as she came. I felt like I was going to explode. With Iris finally climaxing, I let myself think about Emily. Her pale, blue eyes. Her thick lips painted in black lipstick. The tight, black outfits that I'd masturbated over so many times when we were in school together. I came instantly, shooting a huge load into my condom.

When I finished, I collapsed on top of the small, Asian girl.

We laid there and panted for a minute, until she started slapping my back and saying, "Hey, I can't breathe!"

"Sorry, sorry!" I said, rolling off her. I gave her a couple of minutes to recover. There was one more thing that Emily had asked for us to do. "So, do you have any more notes for me?"

Iris rolled over on her side and looked at me like I was a run down old house and she had her own home renovation show. "Tons!"
