My Virgin Sister

“Ohhhhh Ohhhhh Ohhhhhh I’m cumming, Jack!” I push it in and out faster. She’s bucking so wildly that I can barely keep the vibrator in her over-excited pussy.

“Tell me what to do, Sis. Do you want it pushed in and out, or held in, or what?” I’m trying frantically to keep up with her jerky thrusts, as her body reacts to the stimulation of the vibrator.

“Just do whatever you’re doing. I’m cumming!” She grabs the bedspread with her hands, slams her ass down on the bed and closes her legs, trapping the vibrator and my hand between them. “Stop it! Shut it off! Stop it, Jack!” Lisa yells.

“Open your legs, so I can!” I yell, prying her legs apart and turning the vibrator switch to off. She collapses on the bed, her legs twitching and her chest heaving up and down, as she catches her breath.

“Wow! No wonder Mom was relaxed last night!” Lisa says, smiling while she sucks air into her lungs.

“Didn’t Mom use it on her clit, too?” I ask Lisa. “Do you want to try that?”

“Yeah in a minute,” she says, still panting. “Let me catch my breath.” The pink vibrator is still in Lisa’s pussy and I reach over and pick up the egg. It is soaked with Lisa’s juices and I get an idea.

“Hey, you know what you should try? How about we leave the pink vibrator in your pussy and use the egg to stimulate your clit. That should really get you off.”

“Ooh, yeah! I like the way you think, Jack,” Lisa says, spreading her legs apart. “Why don’t you turn the pink one on low and then hold the egg against my clit?”

“Okay. The egg only has one speed, so if it’s too much, we can switch them.” I reach over and turn the pink one on the lowest setting and leave it buried in her pussy. I push the button on the egg-shaped vibrator and hold the vibrating egg against her clit. “How’s that?”

“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!”
