"Mmmmm, you're getting hard again, Bill," she giggled with delight. "And so soon, too."
She squeezed his cock, making her brother moan around her tit. She giggled again when he tried to fuck at her fist, his swollen prickhead poking at her stomach. She let him rub his cock against her and clutched his ass again. "You want to fuck me again, Bill? Did you like fucking me so much, your cock got hard so fast?"
Bill, his mouth filled with his sister's tit, looked up at her, nodding his head, eyes glowing. No longer nervous, he ran his hand along her side, over her hip, then around to feel her ass. Her skirt had come down a bit, and she lifted it so he could touch her naked flesh. Feeling his sister's round ass, he stroked it, then moved, his palm down to caress her deader thigh, too.
Tracy pulled her skirt up so his cock could touch her bare flesh. She felt his prick smearing juices about her stomach, and adjusted herself so his cockhead was moving through the silky hair of her cunt. She lifted his mouth from her tit and tilted his head, kissing him, darting her tongue into his mouth. Shoving his cock between her thighs, she let her brother fuck through them for a while, holding them tightly about his cock. Holding tightly to her brother's ass, she mewled to the sensation of his hard prick rubbing along the fiery, puffy lips of her wet pussy.
"Hold my ass, Bill," she whimpered, arching her cunt toward him. "Ohhh, hold my ass, baby!"
His mouth was devouring her tits again, going from one to the other, his hips jerking back and forth. Tracy squealed when her brother tightened his hand on her ass, grinding her cunt along the shaft of his cock. One of her hands held his bead, smashing his face against her tits. The sudden orgasm throbbing through Tracy's cunt came as a surprise to her. It bubbled hotly, her clit burning.
"Oooh, I'm coming again!" she yelped, digging at his tight ass. "Oh, Bill, I'm coming again!"
"Me, too!" he yelped, his cock gushing hot, creamy come juice along his sister's thighs and shuddering asscheeks. Spurt after spurt splashed upon her flesh, with Tracy whining in a soft voice, her cunt flexing in searing spasms.
"I didn't mean to make a mess, Tracy," he mumbled shyly. "I didn't know I was… I couldn't help it, Tracy."
"Shhh," she soothed. "That's all right, Bill. It's all okay."
Tracy held her brother for a long time, until she heard his soft breathing. Bill had fallen asleep in his sister's arms, his cock still between her thighs. Gently, so as not to awaken him, Tracy pulled away. Bill moaned once as he flopped onto his back, and Tracy stood near his bed, looking down at his glistening cock, her eyes bright, a smile on her lovely face. She felt his jism dripping along her inner thighs. She curled her fingers into her cunt and leaned down, kissing him lightly on the lips.
Tracy found her mother in the living room.
They sat and looked at each other for a moment, not speaking, yet their eyes passing messages back and forth. Susan sat upright, her hands folded in her lap, shoulders straight. Tracy gazed at the thrust of her mother's tits, at the few inches of smooth, slim thigh that showed below the hem of her skirt.
"I saw," Susan said after a bit. "I watched you, Tracy."
"I know, Mother," Tracy replied in a low voice. "So does Bill."
"Did he… did he say anything about me?" Susan asked. "Anything at all?"
"Na," her daughter said.
Susan's expression became a little sad and disappointed.
"Mother, Bill is shy," Tracy told her. "You can't expect him to say anything about you, knowing you saw us fucking. He's afraid we're in trouble."
"The poor darling," Susan whispered. "I don't know what I should do, Tracy. I mean, to help him understand."
"Understand what, Mother?"
"That he isn't in trouble."
They fell silent again until Tracy spoke. "He's probably better than the neighbor," she said.
Susan's head jerked up. "How do you know?"
"Bill is here, he lives here," Tracy explained. "Bill is available and…"
"I should fuck him, fuck my own son?"
"Why not, Mother?"
"He's my son."
"And my brother," Tracy countered. "You saw me fuck him, you saw how excited he was. Oh, Bill will fuck you too. If you want to fuck him, it's going to be up to you."
She told her daughter of her frustrations until she realized her desire, and this led Tracy to tell her mother about her disappointment with her dates. "But that's finished now," Tracy said. "I've got Bill, and he gives me more satisfaction than any damned date I've had."
Susan looked straight at her daughter. "I didn't know you were frustrated Tracy. I guess we're both in the same boat."
"Not anymore, Mother," Tracy said, giving a smile to her mother. "I intend to fuck my brother from now on. Bill is more than eager, and he's a wonderful fuck."
Susan swallowed, then said in a whispery voice, "Hold me a little, Tracy."
Tracy sat beside her mother, wrapping her arms about her. Susan rested her head on her daughter's tit. They held each other for awhile, then silently, their lips pressed together and they were kissing gently. Drawing back, Susan gazed into her daughter's eyes, and with a small, soft whimper, pressed her lips to Tracy's again, kissing her with passion now. Susan whimpered once more as Tracy tightened her arms about her, holding her tightly, hissing back. Susan slipped a hand over Tracy's tit, and when her daughter failed to protest, she curled her fingers into the girl's spongy tit, squeezing it. Tracy now moaned with rising heat and slipped her tongue past her mother's lips, delving into the wet heat. Susan began to suck at her daughter's tongue hungrily, fondling Tracy's tits, shoving her hand into the girl's blouse.
"Ooooh," Tracy mewled with pleasure as her mother played with her tits. She pulled her hand between them, and when her mother shoved her tongue into Tracy's mouth, Tracy began to squeeze her mother's tits. The women squirmed together, each feeling the bubbling heat swelling about in their stomach, radiating to their inner thighs and their cunts.
Tracy didn't protest when she felt her mother's hand starting to slide up her thigh beneath her skirt. It felt good to her, hot and slightly moist. Neither spoke now, but their breathing was loud, coming in excited gasps as they kissed and licked at the other's mouth and lips.
Susan slowly shoved her hand along the satiny flesh of her daughter's thigh, afraid that Tracy would, at any moment, stop her. The feel of her daughter's thigh was good on her hand, and she inched her fingers higher. Finally she was brushing the soft hairs of Tracy's cunt, making Tracy twist and squirm her ass with pleasure. Tracy opened her legs invitingly, and Susan slipped her fingers between them. She felt the wetness on her daughter's inner thighs, the still warm slippery jism. A shiver of ecstasy rippled through her.
"Bill's come juice?" Susan asked in a thick, throaty voice.
Tracy nodded. "After you left, he fucked me between my legs. We both came again, Mother."
"Ohhh, nice, very nice," Susan moaned, running her fingers in the slippery juices near her daughter's cunt. "Can I… you know, see it?"
Tracy nodded, pulling away from her mother and sliding her skirt up. She lifted her rounded ass and pulled her skirt to her waist, spreading her knees. Susan gazed down, seeing her daughter's cunt, seeing the soft triangle of curling hair, the pink and still wet lips of her pussy. Jism glistened on Tracy's smooth thighs with a drop or two still lingering near her clit.
The curves of Tracy's ass, too, were wet with it.
Tracy saw her mother's expression, saw her eyes gleaming and the way her tongue licked across her lips. Susan ran her fingertip into the jizz, then brought it to her mouth. Tracy watched her mother lick it away. "You like it, Mother?" she asked in a throaty voice, feeling excitement building inside her body. "You like Bill's come juice?"
