Unspoken Pleasure by Erotica

My Virgin Sister 13

Lisa jumps up off the lounge chair, forgetting her top isn't fastened. She holds it against her ribs, as it slips below her tits, leaving her sexy, little mounds bouncing freely as we run to the window.

"What happened?" Lisa asks as we position ourselves outside Mom's window, me behind Lisa looking over her shoulder again. "All of a sudden, she freaked out."

Mom comes into her room untying her swimsuit bottom and letting it fall. She kicks it into her bathroom, locks the bedroom door and unfastens her top. Shrugging it off her arms, she tosses it in the bathroom, giving us our first look at her fully erect nipples. We stare at her thick, pink nipples sticking out about 3/4 of an inch from her wide areolas, as she starts massaging her breasts. She keeps one hand on her breasts and moves the other one down across her dark, triangle to her pussy lips. She hastily slips two fingers inside her pussy and starts pumping them in and out.

"Damn, Jack she is really hot!" Lisa whispers, while rubbing her ass against my throbbing cock. "Look at her fingering herself. What happened out here?"

"She bumped her cheek into my cock, when she started to get up, and just sat there staring at it. I thought she was going to grab it, when you asked her to do your legs." As I say this, I pull Lisa's swimsuit bottom down to her feet and she lifts one foot out of it, spreading her legs apart.

"Oh god, Jack. Are you going to fuck me while we watch Mom finger herself. You are so bad! Fuck me, Jack!" I drop my swimsuit to the ground and push my rock hard cock deep into Lisa's dripping wet pussy, from behind. She grinds her ass back against me and I steadily pump in and out of her tight, frothing pussy. Lisa let's her top fall to the ground, as she leans her hands against the side of the house for support. We are both completely naked, fucking in our backyard and spying on our mom, as she fingers herself.

Mom is now lying on the bed on her back, with her knees pulled up, pumping two fingers in and out of her pussy. Her other hand is still pinching her tits and pulling at her nipples. When she stretches her nipples out, they're over an inch long, making her tits look like long, cylindrical cones, rising out of her chest. Suddenly Mom starts bucking against her hand, lifting her ass off the bed. She lets go of her tit and starts rubbing her clit, while still shoving her fingers in and out of her pussy.

"This is amazing, Jack!" Lisa whispers, breathing hard. "She's cumming and I'm about to cum with her. Let's all three of us cum together, Jack! Fuck me harder."

Oh look, she's pulling it out," She says as we watch Mom pull the vibrator half way out of her pussy and push it back in. She pulls her knees up and spreads her legs wide apart, as she fucks the vibrator in and out between her swollen

removing the vibrator from her clit and relaxing her legs. She slides her legs down onto the bed, still wide apart, in a spread eagle position. Her chest is heaving up and down, as she gulps air into her lungs. Her tits are rising and falling with her breathing and her nipples are still very stiff. She turns off the vibrator, holding it in her right hand as she lets her arms fall on the bed on either side of her. Her breathing is still slowing, as she lazily moves the vibrator to her mouth
