My Virgin Sister 15

"Mmmmm It's.... It's.... Ohhh Fuck! It's... Hold it right there, Jack. Don't move it. It's making me cum already! Stop! Turn them off. I want to switch them. The egg vibrates too much or I'm too sensitive or something. Quick, Jack. Switch them around."

I set the egg on the bed and pull the pink vibrator out of her pussy, turning it off. I push the vibrating egg up inside her with my finger, then turning the pink vibrator on low, I hold the tip of it against her clit. She's already jerking against it and I'm having trouble keeping it on her clit.

"Lie still!" I tell her. "It'll only work if it stays against your clit. You can't keep bucking against it and expect it to stay in position." I move between her legs and press my forearm across her mound to hold her still, while I keep the tip of the vibrator against her clit. She's jerking and twitching from the simultaneous vibration inside her pussy and against her clit.

"It feels like an orgasm machine, Jack. I just keep cumming and cumming! Oh Fuck! It's.... It's.... building up a big one! Oh Fuck! God Damn! God Damn! Ohhhhhhhhhh!" Lisa is bucking and thrashing wildly, and I'm trying to hold the tip of the pink vibrator against her clit, when she yells at me to stop. "Stop! Jack! Shut them off! Pull them out! Stop!"

I remove the pink vibrator from her clit and push the button on the egg, shutting it off. Lisa's body is twitching and trembling. She rolls onto her side, curling up in the fetal position, gulping air and moaning softly.

"Mmmmmm Jack," she moans as I pull on the wire and pop the egg out of her drenched pussy. Her juices are oozing from her pussy lips and running down her ass. I lean over and lick them up.

"I haven't had breakfast yet, remember," I whisper as I lick her hot, cream from her ass cheeks and thighs. She's curled up away from me and I'm lying on my side with my feet behind her head and my face pushed up against her ass. I lick all around her pussy lips, and then push her lips apart with my tongue, releasing a hot stream of thick syrup, which I hungrily lap up.

I pull my head back as Lisa rolls over, raising her left knee and giving me access to her pussy from the front. I continue licking her juices, while she lifts my semi-erect cock in her hand and slips the head into her mouth.

"Want to know what it felt like?" she asks, pulling her mouth off my cock and holding up the pink vibrator. "It was like continuous orgasms without the teasing or the build up. It was great, but I can see why Mom started with her fingers and built up to the vibrator. Here, let me show you." Lisa is smiling at me. I stop licking and watch her turn the vibrator on and press it against my cock just under the head. My cock immediately extends to its full length and in no time I'm humping against the vibrator. It feels like a milking machine trying to pull the cum out of my balls.

"Wow! That's amazing. It doesn't feel like anything I've ever felt before." I'm frantically bucking my hips against it as I feel the tension build. "God! I'm going to cum already." Lisa keeps the vibrator against my cock, wraping her lips around the head, just as I explode. She sucks and swallows, as I buck my hips against her mouth, and the vibrator milks all the cum from my balls.

"Okay, stop! Take it off my cock! Fuck that was unreal! It was like instant sex. I came hard but it was over pretty fast. Is that what it felt like to you?" I ask Lisa, as she settles back on the bed, licking her lips and swallowing the last of my cum.

"Yeah, pretty much. But when you had both vibrators going, it was fucking amazing. I think I'd like to try it sometime after you've already given me two or three orgasms with your mouth and your cock, and see what happens, because you're right it was over pretty fast."

"You're insatiable. Do you know that? What will you think of next?" I ask, teasingly.

"Well, I've actually thought of how we might be able to seduce Mom. Want to hear?" Lisa explains her idea and it almost sounds plausible. I can hardly wait. The plan includes me watching through the window, and listening to them, using our cell phones.

We get our chance about two weeks later. It's a Saturday and all three of us are in the pool. We horse around for a while, both of us teasing Mom with as much skin contact as we can. Then Lisa and Mom put suntan lotion on each other while I lie on my back next to them, my bulge apparent in my trunks. I watch Mom squirm, eying my cock, as Lisa rubs suntan lotion up and down Mom's legs, nearly caressing her ass cheeks.

We know the plan is working when Mom abruptly gets up and says she's had enough for the day. As she goes into the house, we head for her window. What we see is nearly an exact replay of what we had seen a few weeks before. Mom locks her bedroom door, strips out of her swimsuit and begins fingering her pussy and pinching her hard nipples. She already has the vibrator with her when she lies down on the bed, finger fucking herself. After cumming with her fingers, she slides the vibrator deep in her sticky, wet pussy and turns it on.

"That's your cue, Sis. Are you ready?" I ask. Lisa's plan includes interrupting Mom just as she's about to cum with the vibrator. That will put Mom at her most vulnerable and give Lisa's plan a greater chance for success. We each have our cell phones and I speed dial hers, as she's walking into the house.

"Hey," I say into my phone, "wait for my signal. And don't forget to put your phone on speaker when you go in Mom's room."

"Don't worry. I won't let you miss anything. You just remember to hit mute so she doesn't hear you jacking off through my phone," Lisa laughs.

"Okay, I'm at her bedroom door," she whispers.

I watch Mom moving the vibrator in and out of her pussy, and just as she's raising her hips off the bed, I give Lisa the signal. "Go now!"

Lisa knocks on Mom's door and tries the door handle on the locked door. "Mom, can I talk to you a minute?" She sounds so innocent.

I watch Mom yell something at the door, pull the vibrator out of her sopping, wet pussy and hide it under her pillow. She gets up, grabs her silk robe from the closet and walks toward the door.

"The vibrator is under her pillow. She's coming to the door in just her robe. You're on!" I say as I hit mute on my cell phone and watch. Lisa must have hit her speakerphone button, because I hear the door open.

"What's wrong, Lisa?" Mom asks.

"Umm," Lisa hesitates, "can I come in and talk to you a minute, Mom?" Mom tied her robe around her waist, but Lisa still gets a great view of her cleavage, as her tits swell out into the opening at the top of the robe, and her hard nipples push against the thin fabric.

"Of course, is something wrong?" Mom leads Lisa into the room and they both sit down on the edge of the bed. I see Lisa nonchalantly lay her phone on Mom's nightstand, speaker side up.

"Mom, you know you've always told us we can talk to you about anything, right?"

"Absolutely, no matter what's wrong, we'll work it out together," Mom says, serious concern showing on her face.

"Oh no! It's nothing like that," Lisa laughs. "I just have a couple of questions, but it's kind of embarrassing to talk about with your mom."

"Oh, come on. Whatever your questions are, I'll try to answer them the best I can without causing you any undue embarrassment. Now what do you want to ask." Mom is clearly relieved that she only has to deal with embarrassment and not a real problem.

"Well. You have that very sexy swimsuit, that doesn't cover as much as mine, yet your pubic hair doesn't show around your swimsuit and mine does. I keep adjusting my suit and yet a few stray hairs are always sticking out and it's embarrassing, especially around boys. Do you shave or trim yours? Can you show me how?"

Mom is smiling. "Yes, Lisa, I do trim my hair so it doesn't show and yes..." Lisa cuts her off before she has a chance to finish.

"Can I see? I want to see how it's trimmed and see if that's what I want to do with mine." Lisa is already pulling Mom's robe open to look at her pussy. I know Lisa's plan isn't about trimming her pubic hair. It's all about getting Mom to expose her pussy to her.

"Hold on," Mom says standing up and untying her robe. "I'll let you see what I'm talking about, just be a little patient." When Mom opens her robe she's facing the window and I get a clear view of her neatly trimmed triangle of hair. I watch Lisa reach her hand out and run her fingers across Mom's patch of short, trimmed pussy hair. Mom takes a deep breath, but doesn't say anything.

"That's all the hair you have? You trim all the rest away. How? Do you trim with the scissors or shave? Look at mine. The hair just goes every which way. It doesn't look sexy like yours." Lisa pulls her swimsuit bottom down and shows Mom her blonde pussy. She brushes her fingers through her hair saying, "See mine's ugly. Not sexy like yours at all."

"It's not ugly at all, dear. It's quite lovely actually, but we can trim it if you like, so it's not so unruly." Mom is concentrating on consoling Lisa and barely notices her bend forward to look up at Mom's pussy from below. This is where her plan is either going to work or not work.

"Mom! You don't have any hair around your vagina, it's totally smooth." Lisa has her fingers on Mom's hair again and runs her thumb across Mom's smoothly shaved pussy lips. Mom steps back out of reach of Lisa's hand and starts pulling her robe closed.

"Mom! You're soaking wet. You are.... Oh my God! That's why you had the door locked, isn't it. Oh, Mom, I'm sorry. Were you... um? I'm sorry I interrupted you, didn't I?" While she's saying this, Lisa is licking the juices off her thumb as if it's the most natural thing in the world.
