This is it, I’m thinking as I bring my knees forward a bit and slowly lower my cock towards her tits. My balls land first, and then I feel the cool pre-cum under my shaft. I press my shaft into her chest with my thumb and she closes her boobs around my cock. I very slowly thrust forward, letting the lube spread. Her warm soft tits feel so good wrapped around my cock. My mouth widens and I look into her eyes, my breath trembling with pleasure. Her mouth opens and I slowly slide back… then forward again, and back.
“Oh god..” I whisper, “That feels amazing.”
I thrust slowly forward again and she squeezes her tits closer together, enveloping my hard wet cock in her soft pillowy tits. I thrust again.. and then again. Slowly at first, becoming a bit quicker with each thrust. I’m fucking my twin sister’s beautiful tits now. More pre-cum adds a soft squishy sound with each thrust. I quicken my pace, but not so much that I’ll cum soon. Slow and steady thrusts, making circles with my hips, moving her body up and down under my weight with each thrust. I lower my head to watch the tip of my cock emerge, then disappear, again and again. We both watch as my cock slides up and down, inside her slippery tits.
“That’s it, big brother..” she sighs, “Fuck my tits.. Slide that big hard cock in and out. It feels so good.
“Yeah baby..” I thrust again.
“Does that feel good, big brother? You like fucking your sister’s tits? Huh?”
“Yeah… yeah.. baby, that feels so good.”
“Yeah big brother, finger my pussy while you fuck my tits..”
I straighten up and reach back. Grabbing her leg, I massage her inner thigh, getting closer and closer to her pussy as I keep thrusting my cock between her tits. I feel her wet pussy hair with my hand and cover her pussy, feeling around for her clit with my middle finger. When I find it I begin swirling my two fingers firmly around it. Her body rocks and she moans to my every touch. Rocking her hips with mine. Fucking my hand while my hand fucks back. She leans up on her elbows so her tits can get a better hold of my dick. Her mouth is wide open, her forehead wrinkles, her eyes glued to mine as she starts bouncing her tits up and down around my cock. Squishing sounds become louder as I plunge two fingers inside her wet warm pussy and I start to finger fuck her. She leans forward more and my cock slides up her chest and past her neck. Still reaching back into her pussy I thrust upward and my cock feels her face. Her eyes close while one hand firmly grabs my balls. Her other hand wraps around the base of my shaft and she guides my cock around her face. Her eyes closed, mouth open, she feels my cock with her face. Rubbing it all over, hugging it. She worships my cock while rolling my balls in her tight grip.
Her tongue is out now. She wants me in her mouth. Flailing her tongue around with her eyes closed, she finds my shaft and gives it a few long licks. Holding my balls, rolling her tongue around the tip of my cock. It feels so good as I start thrusting at her face with my cock. My head rolls back and I feel a deep warm plunge as her head lowers onto my cock, taking in the whole thing. A wave of extasy overcomes my whole body and Kassie starts breathing through her nose. Her mouth now plugged by my rock hard cock. She sucks deep and hard, swirling her tongue with each suck. She swallows my cock whole. Up and down. I grab the back of her head, guiding it up and down while I fuck her mouth. Her head lifts and she takes a long deep breath. A string of spit and cum still connects my dick to her face. She looks up at me and starts jerking me off.
“Yeah baby!” she squeals, “You like that?.. You like it when your sister sucks your cock and jerks you off?”
“Ohh Kassie, yes! Jerk me off baby… jerk your brother off, baby… yeah..”
She pushes me hard and I stumbled onto my back in the grass. I’m laying on my back and I look up to see Kassie, crawling all fours overtop of me. Her wet boobs swaying. She pushes my chest back, grabs my face and plants a long kiss on my lips. Swirling her tongue around mine, she adjusts her body over mine and grabs firmly onto my cock, guiding it towards her gaping wet pussy. She looks longingly into my eyes.
“I love you big brother..” she whispers.
“I love you too, Kassie.”
She sits back and my cock slides right up into her warm pussy. Sitting up straight, I see sweat, cum and all kinds of our juices glistening in the moonlight on her smooth tight body as she grinds her hips deeply around my cock and begins swirling them around and around. I thrust my own hips upward. My thrusts against hers, and Kassie and I are fucking, hard. She leans forward and I pound upward with my legs. I grab the back of her neck and I swallow her tongue. We become one. Twin siblings attached at the face and waist. Outside in the backyard, both sweating and fucking. Trying hard not to make too much noise. Kassie’s pussy is so wet, I swear she has already come, and suddenly I can’t go on for much longer. I bring my face to her ear.
“Kassie…”
“Yeah, baby…?”
“I’m gonna cum..!”
“Yeah baby? You’re gonna come for your sister? … Tell me when, big brother!’
“Now!”
Kassie jumps to her feet and pulls me up by my hands. I’m standing now and Kassie throws herself down in front of me. On her knees, she swallows my cock whole and doesn’t let go. There’s an explosion in my mind and I grab Kassie’s head with both hands. Not a sound leaves my wide open mouth as I feel a long stream of warm cum escape my hard cock and fill up Kassie’s mouth. On her knees, still fingering her pussy, Kassie breathes heavily though her nose as she sucks down my cum, taking it all in hard short swallows. Looking up at me and I down at her, our eyes are locked together as she drains me completely.
After what seems like forever, our bodies become less tense, and Kassie begins slowly letting me out of her mouth. My cock flops out, still swollen but slowly arching back down. Kassie gives it one last kiss and slumps back down on her knees. Both of us breathing heavy, I slump down and sit next to Kassie. She puts her sweaty head on my sweaty shoulder.. then we both slowly lean back and lie down again under the starts, buth soaking wet and speechless.
“Well…” Kassie breathes out, “Well that happened..”
“Haha!” I manage to chuckle, “That was amazing.. You’re amazing…”
“Thanks,” she looks over at me, “We can’t tell anybody.”
“To the grave,” I say, looking back.
“And we can’t do that again for a little while..”
“I know..”
“Well…” she says, “Maybe soon… but not too soon.”
“I know.”
Kassie rolls toward me, and I put my arm behind her head. Cuddling on the ground in our backyard, she puts her hand across my chest. But, changing her mind, moves it down and cups her fingers over my drained limp cock.
“I can’t believe my brother has such a big fucking cock,” she whispers.
“Haha,” I smile, “Well I thought it fit quite nicely.”
We lay there, still for a few minutes under the night sky. Her grip tightens around my shaft, and it starts to swell again. Still slippery with our juices, she squeezes and moves her hand slowly up and down. I sigh as my cock slowly becomes hard again in her firm grip.
“You wanna go again?” she asks.
“Ugggh…” I sigh, “Yes… but give me a few minutes.”
“Ok,” she says, but she’s already jerking me off.
“And maybe inside this time… quietly.”
“Ok.”
Her grip tightens and she’s sliding me in and out of her warm hand.
“Oh my god..” I sigh, “You feel so good, baby sister.”
“Fuck me again, big brother…”
