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?”
