Seduced by my brother's girlfriend

“Yeah! Yeah! that’s it baby.” “Don’t stop. Yeah, right there” Blake moans, and I continue the steady motion on my c**t. Blake’s not here though, she’s in the next room with my brother, Miles and he’s the one making her scream like that. I’m just imagining that it’s me in Miles’ place. “f**k, Blake” I moan increasing the pace and squeezing my naked boob. How did I end up in this shitty situation is what you might be wondering. In my defence I liked her first before Miles even noticed her. I can’t pinpoint the exact moment when I fell for her, but I remember waking up one morning and she was all I could think about. The girl who sat in front of me in Spanish class. It didn’t help that I’m a cheerleader who was in a cliché relationship with the school’s star quarterback or that a few months later Blake started sleeping with my school dropout brother. Blake and I are both seniors at Western High and we’re both eighteen. “s**t I’m cummi… Ah! f**k” Blake screams her voice a bit muffled but still very audible. Thank my cheap skate parents for these very thin walls. The house is now silent, but I continue playing with myself pressing a finger against my wet hole then slowly sliding it in while simultaneously pressing another against my c**t. “Aaaah!” I press my face into my pillow to suppress my moan. I imagine Blake with her beautiful t**s on display scissoring me and the fantasy is driving me insane. The finger inside me moves faster and I’m almost there, I just need… “Hey Cas, you awake?” Blake shouts knocking on my bedroom door. “s**t” I whisper pulling out my finger and jumping off the bed. I pick up a t-shirt off the floor, slide it on and rush to the door and open it. “Hey wassup?” I fake yawn. Blake is butt naked standing in the hallway. I feel my p***y pulse. Shit “Your brother’s being a d**k again. Can I crash with you tonight?” she’s not even trying to cover herself up. “Yeah, sure come in” I move out of the doorway, and she walks in. “So, what did Miles do again?” I ask shutting the door and following her in but she’s facing away from me and all I can focus on is her bare ass. “Just normal stupid boy stuff. Nice room by the way” she says finally turning to look my way but the view is even worse from this angle. My p***y is clenching begging for her. “Thanks.” I blush. Yes, a compliment from Blake Harper can drive me to my knees. She moves to my bed and climbs into my blankets and I follow her in. My bed isn’t that big and we are so close that I can feel the heat vibrating off her. I’m facing the ceiling and she’s facing away from me. “Goodnight” she yawns. “Goodnight” I say back. Almost an hour passes and I’m still wide awake and my c**t is throbbing. I look over to Blake and notice she’s breathing softly, lost in sleep. I can’t ignore the fact that she’s naked in my bed. Emphasis on naked. I try to ignore her presence but that’s like trying to ignore the sun. Impossible. I know I shouldn’t masturbate with her here but then this is her first time in my bed and probably last. Oh, f**k it! I slowly move my hand down my belly and stop when my fingers reach my p***y. Slowly my fingers make circles on my c**t and I suppress a moan. I continue the motions tempted to touch her, but I don’t. The heat rolling off her is enough for now. I close my eyes and gasp slightly increasing the motion on my c**t. “f**k” I gasp again and quickly open my eyes to check on her. She’s still asleep. I increase the speed again completely losing myself in the pleasure. My hips start to slightly move matching the motion of my fingers. This feels so good. This time I slip two fingers into my dripping p***y clamping a hand on my mouth, moaning into my hand. I pump into my dripping wet p***y the juices slipping out and onto my ass. Sweat drips down my forehead and I keep increasing the speed just not getting enough, needing more. I need to touch her. I can’t touch her, but I need to touch her right now. I pull out my fingers and grab the pillow under my head. I put it between my legs and start grinding on it pretending that it’s her. I press the pillow onto my p***y grinding on it faster and harder. I’m moving so fast enjoying the friction when the pillow is pulled off me. My eyes jump open and Blake straddles me. “You were so loud and turned me on so let me help you out” she says already slowly grinding herself on me. “Blake we can’t” I moan failing to ignore the pleasure she’s giving me “We can Cas just this one time” “What if Miles hears?” “Then you better keep it down” she whispers moving to lie on top of me. Her boobs smash into mine and she moves her arm under her until she finds my dripping wet p***y that’s been begging for her. She inserts two fingers and curls them pulling a loud moan out of me. “Shhhh remember we don’t want big bro to hear” she smirks moving her fingers in a way I could never do to myself. Her fingers hit the spot over and over again. I grab her ass and start groping it. I spread her ass chicks wide open grabbing them harder and she softly moans. I feel something wet sliding onto my p***y and realise that it’s Blake’s juices dripping onto me. She increases the speed inside me and my p***y starts making squeaky sounds that turn me on even more. “You look so good wet” Blake moans when I slide two fingers inside her. Her juices increase completely wetting my hand and my sheets. “Faster” I groan into her ear and she follows my orders moving faster. Now our bodies are grinding against each other. I add a third finger and curl all three and she starts bouncing her ass to increase the friction. Then our lips collide into the most feral kiss as we both moan into each other’s mouths. I use my other hand to slap her bare ass and my orgasm crashes into me the same time as hers. We both ride it out still fingering each other until she finally goes limp on top of me my fingers still in her and hers still in mine. I can feel her p***y clenching and unclenching. “This feels a million times better than anything your brother has ever done to me” she says rolling off me. She’s now sleeping next to me facing me with a small smile on her face. “Maybe I chose the wrong sibling” she wraps her arm around me pooling flush against her “and next time I’m totally eating you out” “Next time? You said this was a one time thing” I say not hating the idea of a next time. She doesn’t answer me she’s already dosed off.
