I pull on her nipple, pinching it and stretching it out as far as it will go.
I can tell she’s getting close.
I switch to her left tit and do the same thing.
I manage to push a second finger up inside her pussy, while she keeps bouncing up and down as hard as she can.
Suddenly, she stops moving and I feel her pussy clamp around my fingers, pulsing in and out.
It’s like I can feel her heartbeat through her pussy walls.
She grabs my hand and holds my thumb still, while she pushes down hard on my soaking wet fingers.
I let go of her tit and reached my hand around her back, pulling her down on me.
She collapses on my chest with her head on my shoulder and my fingers still in her sopping, wet pussy.
She just lies there, catching her breath.
With her naked body stretched across me, I move my hand down to her ass and gave it a gentle squeeze.
All my fantasies are coming true.
I’ve played with her tits, finger fucked her pussy and even shot my cum in her mouth.
What an afternoon, and I have Alvin to thank for it.
But I think he’ll be the one thanking me before this is over.
I look at the clock again and begin pulling my fingers out of her pussy.
“Not yet, Collins.
Please leave it there for a little longer,” she pleads, squeezing her legs together to trap my fingers.
“That was amazing, I didn’t know anything could feel like that.
You are the best brother ever!” She lifts her head and starts kissing me.
It isn’t a stepsisterly kiss, either.
She’s pushing her tongue in my mouth and rocking her body slightly up and down so that her nipples are lightly scraping across my chest and my fingers are sliding in and out of her slippery, wet pussy.
“Lilly, we really don’t have time.
I’m sorry.
I’ll make it up to you tomorrow, I promise.
Then, I push her back and slide off her bed.
“Let’s put our swimsuits on and get in the pool before Mom comes home.” I figure the pool will help us cool off and get rid of the smell of sex.
Later that night before we go to bed, I go into Lilly’s room and hand her a piece of paper.
“Some homework for you on that project we’re working on,” I say, smiling at her.
She takes the paper and reads the title “Mind-blowing Blowjob Techniques” it says in bold letters across the top of the page.
“Where did you get this?” she asks, laughing.
“I downloaded it with my file sharing software.
I just searched oral sex technique.
doc and there it was.
Study it and be ready after school tomorrow for an “oral” exam,” I tease as I go back to my room.
I have my own homework to do.
When I was searching for blowjob techniques, I also discovered sensual oral techniques for eating pussy.
I figure if I’m going to take this to the next level with Lilly, I had better have great technique, too.
After school the next day, Lilly and I walk home together.
“I can’t wait until we get home!” Lilly says, hardly able to control herself.
“I’m really looking forward to our practice, today.”
”So am I, but I have an idea,” I explain to her as we walk.
“When we get home, let’s pretend that I’m Alvin and you’ve invited him over after school.
Tell him you’ve been thinking about what you guys were talking about the other night.
Then, when you get in the house, take him into your bedroom and tell him you’re sorry that you haven’t thought about his needs and you want to make it up to him.
What do you think?” I have another reason why I want her to start thinking about her and Alvin in her bedroom.
When it happens, I want to watch through the window.
“Okay.
I did my homework,” she says, smiling.
“I think you’ll like what I’ve got planned for you, Collins.” Lilly skips ahead of me.
“Come on!”
Inside the house, Lilly turns to me.
“Thanks for coming over, Alvin,” she says.
“Why don’t we go into my bedroom?
We can talk while I change.” She takes my hand and leads me down the hallway to her bedroom.
“Kick off your shoes and get comfortable on my bed, while I get out of my school clothes.” She smiles while she unbuttons her blouse and slips it off her shoulders.
“I’ve been thinking, Alvin,” she says, as she unhooks her bra and slides it off her arms.
Her tits bounce gently and I can see her nipples are already hard.
So is my cock!
“The way you touched me the other night felt really good, but I haven’t done anything to help you feel good.” She unzips her skirt, slips it down and pulls it off her legs.
With just her panties on, she starts walking towards the bed.
“I want to make it up to you, now, Alvin.
Stand up,” she says, pulling me to my feet and unbuttoning my shirt.
She slips it off my shoulders, and then unsnaps my jeans.
Pulling down my zipper, she begins tugging my jeans down and I lift each leg so she can pull them all the way off.
I’m standing there in just my boxers.
Her hard nipples brush against my chest, as she leans up to whisper in my ear.
“I want to suck your cock,” she whispers.
“I want to make you cum in my mouth.
I want to swallow your cum and then lick you clean.” Wow!
She really paid attention to the section on talking dirty and teasing.
My cock is sticking straight out, making a tent in my boxer shorts.
Lilly kneels down, pulls the elastic of my boxers out over my hard cock and slips them down my legs.
She slides back up my body, rubbing her tits against me as she stands up.
