“What’re you watching?”
He slams his laptop shut, and yanks his headphones off so hard it makes his hair stand up on one half of his head.
“Nothing,” he lies.
“I’ll bet,” you laugh, walking further into his room after shutting his door. “Looks like whatever you weren’t watching was fun.”
He flushes red, the color disappearing underneath the collar of his shirt. “I-it’s nothing important.”
You hum and climb into bed next to him, watching his legs twitch under the blanket. Nodding at his laptop, you pat his lap, palm nearly brushing his obvious hard-on.
“C’mon little brother, show me,” you coo into his ear, and he whimpers.
Hands trembling with nerves, he places the laptop on his right thigh, the one closest to you, and pulls open the screen. Using his thumbprint, the computer brightens and the last tab comes into view.
“Oooh what have we here,” you murmur, eyes bright at the paused video. “Who knew my sweet little brother liked big tits, hmm?”
A low moan slips from him, cock jumping under the blanket. “D-don’t say that.”
“What?” You tease. “Tits?”
“Y-yeah,” he breathes out, eyes slipping from the screen to your chest.
Reaching over, you press play on the video. A tinny sound echos from his dropped headphones laying on the side of his bed, but neither of you move to alter it. His eyes flick back to the screen and his fists clench atop the sheets. Your own gaze bounces, pun unintended, from the pair of breasts on the screen to your step brother’s face.
“You like that?” You whisper against his ear and he shivers with a nod. “Tell me.”
“I like how soft they look,” his voice drops low, like he’s too turned on to whisper back. “Fuck, I love how they jiggle. And seeing how hard her nipples look make me wanna suck on’em.”
He slides his hand under the blanket, and you giggle at his neediness. He begins to pull it away, cheeks red, when you grab his forearm.
“Keep touching yourself,” you murmur, lips grazing his jaw. “I wanna see you cum.”
“Sis,” he whines, hands shoving the blanket away so he can tug on his leaking uncut cock.
“Good boy,” you tease and he moans, hand squeezing his tip until precum oozes around his fingers.
“Now, I want you to watch the screen and tell me what you like.” Kissing his cheek, you run your finger down his forearm, tracing the muscle as he jacks off. “Then I want you to cum all over my tits.”
“Fuck, fuck,” he hisses, grabbing the base of his cock tightly. “I don’t know if I can last that long.”
“Yes, you can,” you simper, pulling back to take your top off, baring your breasts to his greedy eyes.
“I love your tits,” he mumbles. “I wanna suck on your nipples til you cry.”
“Yeah?” The word comes out more breathless than intended but you don’t care.
“Mmhmm. I wanna nurse on your tits while you jerk me off. Fuck, or just squeeze ‘em and play with them while you tell me how gross I am.”
His hand picks up speed again, jerking himself off faster and rougher, the shiny head peeking from the tunnel of his fist.
“Is that what you like?” You whisper, crawling into his lap, sitting on his thighs and yet still not touching his leaking cock. “Want me to tell you that you’re a gross pervert for getting off on his big sis.”
Groaning, he pushes the laptop away, video still playing but neither of you taking it in; his blown out gaze stays locked onto your peaked nipples.
“Tell me that I’m a bad boy,” he pants, leaning forward and pressing his face into your breasts. “God, tell me I’m a bad little brother for wanting his sister’s sexy tits. That it’s wrong he wants to cum all over your cute nipples.”
A low groan vibrates his chest, tongue dragging across your breasts before his lips brush across a stiff nipple. Sucking it greedily into his mouth, he latches his teeth around the bud, tongue lapping at you until you squirm.
“Such a bad baby brother,” you moan, hands tangling in his sandy blonde hair. He grunts and suckles on your nipple even harder, teeth nipping the sensitive bud before swapping to the opposite breast.
Pulling his head away, he whines, eyelashes fluttering. “Sis, please just let me suck on your tits. Please, I need it so bad.”
Clicking your tongue, you yank his head back until his breath hitches, cock jumping in his fist at the twinge in his neck. “Hush and take off my clothes.”
Hands fumbling since he’s unable to face you head on, his fingers fumble but all too soon your shorts and panties are tossed into the floor. Readjusting yourself in his lap, you sandwich his cock between your cunt lips, his tip leaking precum all over your swollen clit until it drips onto his abdomen.
Grinding against him sends frisson’s of heat to pool in your belly, your cunt wet and slippery as it glides against his thick cock.
“So g-good,” he shudders, hands gripping your breasts hard enough the fat dimples between his fingers. “God, I’m gonna cum all over your pussy.”
“Mmm, gonna get me all sticky, little brother?”
Panting, he pulls against your hold on his hair and you let him fall back into your breasts, mouth eagerly seeking out your nipples. Smushing your tits together, he nips and licks your stiff buds, running his tongue back and forth across both nipples over and over until you rock your hips down harder. Humming, his eyes slip shut and he squeezes your breasts and kisses the underside of each one.
“Sis, I’m so close. Fuck, your soft little pussy is gonna make me nut,” he whimpers. “And your sexy tits, unh, shit, I don’t know if I can hold off any longer.”
His stiff cock rubs your clit perfectly, sending more slick to coat his fat length. “Aww, you don’t wanna cum all over my nipples, baby brother?”
“I-I want to,” he moans, tongue swiping across the swell of your breasts. “But wanna make you feel good, too.”
“Aren’t you cute?” You simper and his cock flexes against your pussy, precum weeping from the tip and coating more of your clit. “Cum on my pussy and then you can play with my tits til you get it up again, how about that?”
“Yes,” he hisses out, humping against your soaked cunt. “Fuck, you’re so perfect. I love you sis, god, I’m gonna cum all over you perfect little pussy and then cream your fat tits.”
Your fingers tug on his hair and he keens, mouth seeking out your stiff peaks like a mewling baby. Latching onto your nipple, he suckles and bites the bud until you’re moaning. Rutting against each other, you both chase after mindless pleasure until Leon breaks first. His cock pulses and throbs against your pussy, shooting his load all over your cunt and clit and thighs. Hot, sticky ropes of cum paint your skin like a Rorschach test.
He repeatedly bites down on your nipples hard enough to bruise and rubs his cum covered tip into your pudgy clit until you climax. Your toes curl, and you bite your lip to keep down the noise threatening to spill from your lips. Your swollen bundle of nerves buzz with your orgasm, and you ride out the aftershocks with slow grinding thrusts. Leon eases up, kissing the tips of your breasts reverently and sinks back against his headboard.
As you slide up his body, his half hard cock twitches from where it presses in between your thighs. You drop a quick kiss to his jaw and he sucks in a breath.
“C’mon little brother, play with my nipples so you can cream my tits.”
