*****
Squirming and tingling all over in anticipation, Annie tried to sit still on her bed, waiting. The room was dark and silent, only the pounding beat of her heart filled her ears. She had turned off her bedside lamp when she heard the car pull into the driveway, wanting them to think she was asleep. It worked.
She heard their careful steps as they passed her doorway on the way to his room. She listened to them walking down the hall, whispering. Her brother Eric's deep warm voice answered in a hushed tone to his girlfriend Carol's chirping murmurs, assuring her that yes, it was okay, everyone was asleep. Then came the sound of Eric's bedroom's door closing.
Annie bit her lips as she counted the minutes, knowing she should give them some time to get started before she acted. She ached to jump off her bed but she restrained herself, not wanting to spoil it all by rushing things.
She crossed and uncrossed her legs, brushing her naked thighs together. Her thick pebble-hard nipples were brushing against the cotton of the flimsy T-shirt she wore to bed, teasing her already inflamed senses as she tried to picture what was happening in Eric's room. She imagined them kissing, groping at each other as they fumbled to take their clothes off. She pictured them rushing and stumbling through his room, tearing off one another's underwear, caressing and grabbing and licking the other's naked flesh, hungry for more as they fell in a tangled heap on his bed.
Annie could almost see her brother's strong hands running all over Carol's smooth body, his lips on hers, his body pressing her down against the mattress, pinning her to the bed under his toned chest. The mere idea of Eric's touch, the imagined feel of his fingers, of his closeness, of his labored breath; it was all so hot, even just in her head. It made Annie shiver, compelling her to get up and go.
Fighting the impulse to move, torturing herself by waiting yet knowing that it was better this way, Annie reached a slender hand between her legs. She was already wet. The heat and moisture of her pussy were obvious even through her panties. Her digits trembled. The instinct to pull her underwear aside and rub her clit to get a modicum of relief almost overpowered her resolve to do things right.
Sighing, feeling her arousal bubble and simmer inside her, Annie waited. Staying as still as possible, she gave them another couple of minutes, counting down the seconds. When she reached zero, she got off the bed and crossed her room.
Quiet as a mouse, Annie entered her en-suite bathroom, the bathroom that served both hers and her big brother's bedroom. It made her snicker, half in self-pity and half in excitement, to think that for eighteen years this had been just a bathroom while lately it had become the setting of a secret ritual she couldn't get enough of.
Walking on her tiptoes, Annie crossed the cold tiled floor and reached the door leading to Eric's room. She could hear low groans and wet gurgling sounds as she pressed herself against the door-frame. Her heart was racing as she slowly, ever so slowly, pushed on the door. Careful not make it creak, her hand trembling with barely contained excitement, millimeter by millimeter she cracked the door open just enough for her to peek inside.
From where she was looking, Annie could see right across her brother's room. His bed was exactly in her line of sight. She strangled a moan in her throat as she took in the scene before her.
Eric was sitting on the edge of his bed, naked, his head thrown back, his handsome face distorted in pleasure. Kneeling on the floor between his legs, wearing only a blue thong that rode up between her firm taut asscheeks, Carol was sucking his cock. She was slobbering saliva all over his big pole as she slid her lips up and down his length in a slow bobbing rhythm, her hand pumping him at the base. Carol's mouth looked obscenely stretched as she tried to take more of Eric's girthy meat down her throat at each plunge.
Watching her brother getting a blowjob from his slim, pretty girlfriend made Annie crazy with desire. In a flash, without removing her eyes from the fellating action, she pulled her panties down her thighs and stabbed her hand to her needy pussy, dipping her fingers in her creamy moisture. As soon as her fingertips made contact with her clit, Annie shook all over, the bottled-up desire she had strained to control so far finally overflowing in a mini-climax. She sighed in long-awaited relief and kept rubbing her clit while she feasted her eyes on her brother's spit-glossy cock disappearing into Carol's mouth.
As Eric's moans got louder and he started pumping his shaft up into his girlfriend's face, so did Annie's digits whirl faster on her slick engorged nub. The squishy choking sounds coming from Carol's cock-clogged mouth turned Annie on immensely, as they did Eric. While Annie neared her climax, her brother started humping his girlfriend's face with abandon, his hands sinking in her brown hair as he held her head down on his twitching shaft.
"Oh yeaaahh, I'm gonna cum... Ahhh fuck!"
Carol's eyes bugged out as the fat cock in her mouth throbbed and pulsed, unleashing a torrent of thick cum straight down her throat. She tried to remove her mouth from Eric's ejaculating pole, but her boyfriend held her head down, forcing her to swallow his load.
While her brother groaned in climax and bucked his hips into his girlfriend's face, Annie shook and leaned against the door-frame, orgasming on her clit-strumming fingers. Through lust-glazed eyes she watched Carol squirm and finally manage to lift her face from Eric's lap, spluttering and coughing as his last spurts hit her face, painting her cheeks, chin and nose in white gooey seed.
"Damn it, Eric!" Carol barked, her lips curled in disgust, "I told you I don't like it!"
Hearing that, Annie cringed. Her tongue was unconsciously licking her lips as she basked in the lewd sight of her brother's creamy sperm dribbling down Carol's face. Thick ropes of cum and saliva connected Eric's slippery and still plump cock to his girlfriend's lips as Carol reached for his discarded T-shirt, cleaning off his abundant semen with it. Seeing her brother's milky seed wasted like that shocked Annie, who, not for the first time, wished she could trade places with Carol.
