I Spy on My Sister with Her Boyfriend

There is little left until dawn and I hear my sister arriving with her boyfriend. I was watching a series in my room, with all the lights in the house turned off, and managed to turn off the computer so it would seem like I'm sleeping. They enter laughing and try to speak in a low voice although our parents are away on vacation.

She goes into the bathroom and he enters her room and turns on the computer to put music on. She returns and says something, he responds and leaves to go to the bathroom as well. I listen to their sounds, his making pee against the water in the toilet and hers, more useless but in my imagination more perverse because I imagine her taking off her clothes.

Before they would start looking for me, while she was changing, I was spying on them and knew the color and shape of each piece of clothing she put on. I saw her enter wrapped in a towel and then take it off, how she looked at herself naked in the mirror and then saw her get dressed. She lowered the blind and, like addicts, my body starts to fill with adrenaline and one idea, obsessive, installs itself in my brain and hits me over and over again: she's changing, she's undressing, she's naked... I go out onto the balcony and thank these old wooden blinds that, combined with my perversion, have set up the device that lets me spy on her for years.

The boyfriend comes out of the bathroom and goes into the room, closes the door and my ears are filled with the sound of the blind going down. I tremble, full of adrenaline.

Crouched down in an angle where I can study without being seen from the street but also get a panoramic view of the bed, mirror, and closet, I put myself to spy. Jimena lifted her jeans skirt up to her waist like it was a belt and walks around the room showing off the green water-colored panties that aren't a thing but since she has big booty they fit like they were meant for it. She still has the white muscular bra, two sizes bigger, which she wears with a white undershirt below. She has small tits, a little pile of meat and the nipple is brown. Her tits are mine beautiful women of the world but she didn't care about it. That's why she flaunts her Booty so much. Diego calls her. I like her boyfriend and her even more because he leaves what he was doing and comes to find him, lying in bed with a jeans pant, no shirt and barefoot. When Jimena met him, she had been dating for a few years and was used to it, bored. That, plus the dude's perversion, made them a winner in the lottery of cheating. Diego tells her not to do it with his finger and she laughs, gets up from bed and lowers her jeans pant, putting her hands inside and taking out her green thong. The three of us are very hot. He comes back with his finger and she turns around, dancing in place and slowly raising her pants. Her Booty appears, the part of her body where she feels most secure, naked, and when she spreads her legs, Diego and I see the shadow of her shell appear. She turns around and walks decisively to the bed. I can't tear my gaze away from her pubic area. Meanwhile, Diego takes out his cock outside the zipper. It's a fat cock that stands out quite a bit, brown in color, contrasting with her body so white. It's like she has someone else's cock, a pervert or an evil spirit who is about to make my sister's party a wild one. She sits on the bed and grabs his cock, caressing it gently and talking, looking at each other's faces but her hand wraps around the base of his cock, goes up, strokes the tip with all her fingers and down, stretching the skin. She unbuttons him and tries to pull off his pants. He laughs and holds onto his cock, making her suck on it. She leans in and lifts his pants from his feet and up, caressing his legs until she grabs his new cock again. Now she's stroking it with both hands. Sometimes she grabs his balls and holds them, squeezing them very gently, and doesn't take long to put it in her mouth. She's excited and uses her lips and tongue a lot. She's licking the tip, rubbing her lips over the head and down the shaft, puts it in her mouth, doesn't spare anything. He tries put it on top of parachute her but she doesn't want to. Kneeling between his legs she takes off her bra and throws it against the window. I want to lift him up but my fingers hit the wood. Clumsily my sister adjusts herself on top of Diego's cock and starts sitting down. She has one hand holding onto his cock and the other resting on his chest. When the cock goes in alone she puts the other hand on her boyfriend's belly and sits down on top of the whole cock. It starts moving. He grabs her ass and shakes it, pulls it off his sweaty legs and lets it fall back down. That movement opens her up more and the cock goes in, she rides it smoothly until one of his nipples gets bitten and without letting go tries to stretch it with her lips. Jimena increases the pace and her moans pass through the glass and the windowpane, filling my ears like the music from a movie where she acts as a girl with her Booty, who fucks her new boyfriend without worrying about anything.

Diego wants to change positions and makes her stand up, he also gets up and they go to the computer chair, sit down and adjust her towards where I am. She obeys him and slowly lets herself fall back onto that cock. Now I can see his nipples scratching the muscle and her white pubis transpiring. I can see a part of her cock appearing and disappearing but it distracts me from looking at my sister's face. This girl is in love with this dude and besides he's a great cocksucker. Both things provoke those feelings of surrendering without shame.

She moves her Booty on top of the cock, pushes to feel like she's going all the way in and opens her mouth to breathe, agitated. Diego grabs onto the remaining cock that's left in his belt, pushing with force to cum and she feels it, shaking her Booty as if milking it and ends up cumming too.

She cleans herself off with the green underwear, the cum from him and her own liquids. After that she throws them into the dirty laundry basket and gets into the bath water that Diego has already taken.

Tomorrow when they leave I'll recover my sister's clothes to jerk off. I plan to do just as soon as I get back to my room.
