I fucked my brother last night, Livy thought, a shiver running down her spine as she lay in bed. The morning sun slanted through the blinds and cast a striped pattern over the rumpled blankets, and the spot Adam so recently lay in was vacant.
Outside it was a crisp December day, and the house was silent, the rest of the family having gone out to brunch. Livy had begged off, faked sick, wanted time to think over the events of the previous night. Fucked my brother... and her hand slipped beneath the sheets, running over her pointed nipples, down the goose bumped flesh of her stomach, and into the wet spot between her thighs. It's wrong to fuck your brother, she thought as her finger tips played over her clitoris the way his did last night. But it felt so good.
He was home from college, a new person compared with the nervous high school graduate that left her in the Fall. Now he walked with an air of confidence, bolstered by his new popularity with the ladies at school, sporting mature, intelligent glasses and letting his curly hair grow long and wild. Mother hated it, of course, putting 'hair cut' on his list of vacation chores, but Livy liked the change.
She herself hadn't changed much in the four months he was gone. She moved into his room, repainted the walls, then it was life as usual, her own life as a community college student trickling by.
Then came the holidays, Adam returned, and Grandma and Grandpa came up from Florida to spend the week. They got Livy's-old-room-turned-guest-bedroom, and Mother set up a futon at the foot of Livy's bed for Adam.
"I'm sorry," she'd apologized. "This isn't ideal, but it's just for a couple of nights. I really thought they would want to stay at a hotel."
Brother, brother, brother. Her fingers swirled around her clit, sending waves of pleasure through her body like radar echoing out from a single point. She replayed every moment behind her eyelids while her fingers slipped inside herself. Fuck me, fuck me fuck me!
The first night, he brushed his teeth with the bathroom door open and she watched silently from the bed as the shape of his cock jiggled back and forth in his pajama bottoms with each thrust of the brush. Her eyes explored his bare chest and the smooth curve of his back when he turned away to rinse. He came into the room and took off the foreign glasses, becoming her brother Adam again as he climbed under the futon covers. She went to sleep feeling very conflicted, knowing she should feel shame at having looked at him that way, but there was no feeling but lust inside her.
"Motherfucker this futon sucks." These were the words she awoke to the next morning as Adam sat up, clutching his back and grimacing.
"Well," she ventured, her heart racing involuntarily, "we could share the bed if you want. It's big enough."
He looked nervous too. Laughed. "That is my bed you're in. It's only fair."
So last night he climbed tentatively in beside her, being careful to respect the invisible line down the center of the bed. "Good night, sis."
