"C'mon, sis, what harm would it do?" Jack asked again in exasperation. "It's not like your pussy or mouth, or even your ass for that matter, have never been used before."
Sophie rolled on to her back from her side facing away from him and glared without saying a word. She wasn't particularly happy about his request but she never could stay mad at him for long, especially when he twirled one of her nipples between his fingers as he was doing just then.
"C'mon, sis, it will only be six other guys besides me for your first time. You don't know anyone other than Ben and you already fucked him before. The money will be really good too and you are always complaining about not having enough after tuition and such."
She let out a low moan, the pinch of her nipple rippling down to her already sticky pussy. Her brother's sperm was still seeping out of her with some crusting on her pussy lips while most dribbled down over her asshole to puddle under her ass cheeks.
"OK, before I say I'll do it for sure, tell me exactly how this is going to work and you will keep me safe," Sophie murmured, turning to her brother so she could wrap her fingers around his half hard dick still slippery with the remnants of his own cum and her pussy juices.
Jack grinned and leaned forward to flick his tongue across one of the erect nipples capping her tiny conical tits. Sophie groaned again and threw her knee up over his thigh, some of the gooey mixture leaking out of her cunt smearing over his hip.
"Like I said before," Jack continued, shivering slightly when she ran her fingertip over the sensitive head of his dick, "Ben's getting married and I have to put on the bachelor party. All the other guys coming are our classmates and you never met any of them. I won't even tell them your my younger sister. We're all chipping in to cover the room, booze and entertainment...you. You get everything after those other costs, so you start getting some cash right up front. All you need to do for that is strip real sexy like and parade around naked for a while. If anyone wants more, that's entirely up to you if you want to do it or how much you charge. I'll be there the whole time, so you'll be safe."
When she started cuddling up under his arm, Jack was pretty sure she was going to agree. He stretched his arm over her shoulder, dragging his hand down over her back until brushing across her ass and splitting her cheeks with one finger. She trembled again and pressed her ass back against his hand until his fingertip swirled around her sensitive asshole.
"Yeah, she's gonna do it,"
Jack thought to himself before pushing her onto her back and kissing her deeply.
His sister returned the kiss with growing passion, feeling her pussy quiver even before the increasing hardness of his dick pressed against her belly. He pushed her legs up, spreading her thighs and pussy lips. She grabbed her own legs behind her knees and pulled them even higher.
"My ass...fuck me...in my ass...this time," she gasped, rubbing her clit furiously as his mushroom head split her asshole and her brother buried his cumming cock deep in her bowels.
Sophie knew she was going to do it from the moment her brother first mentioned the idea. She just wanted to string him along some and make him squirm before agreeing.
The idea appealed to her for several reasons besides the money, which she really needed to finish her second year at the university. She wanted to fuck Ben again anyway after that time last summer with him and her brother and his bachelor party might well be her last chance for a while. Besides, she was finally ready and this was her first chance to fuck and suck a bunch of guys she didn't know for money as opposed to the regular family gatherings.
After Jack finished cumming in her ass, he collapsed on the bed and nodded off to sleep. Sophie got up, wiped the jism leaking from her pussy and ass and went to get something cold to drink.
**********
When she entered the family room, she saw her mother hunched over the computer. Sophie walked up behind her and wrapped her arms around her neck, letting her hands roam down to twirl her mother's dark erect nipples.
"What are you watching, Mama?" Sophie asked, knowing before saying a word how her mother would respond.
"Oh you know, sweetie, my favorite videos, the ones with young girls playing with older women," Lena responded, "the way I like you to play with me."
On the screen, a woman at least her mother's age, with a big ass and floppy tits, was eagerly licking a much younger woman's smooth bare pussy while pounding two fingers into her pussy and one into her asshole. Sophie could feel her mother's arm moving back and forth as she played with her own pussy.
"Want me to help you out, Mama?" Sophie asked as her mother began to tremble, her usual precursor to a sloppy orgasm.
"It's...OK...sweetie...I'm...I'm already...CUMMING!" Lena screeched, a gusher of her pussy juices spurting out under the desk to puddle on the floor, before she collapsed back into the chair.
"Damn, Mama, I think you are squirting more and more every day," Sophie murmured in her mother's ear and, with another loving pinch of Lena's nipples, walked into the kitchen.
Her father stood at the counter wearing only an apron as he chopped and sliced in preparation for dinner. Sophie stepped up behind him, stood on her tiptoes and flicked her tongue into his ear. At the same time, she slipped a hand under the apron to fondle his flaccid dick and low hanging balls. He stopped chopping and pressed his ass back against her.
"Keep that up and I'll either cut off a finger or will have to fuck you right here," he grinned as his dick stiffened in his younger daughter's hand.
"Decisions...decisions...decisions," she laughed before pulling her hand away from his cock and giving him a gentle slap on the ass. "Tell you what...you finish making dinner and you can have my pussy for dessert. Besides, I need to talk to Anna."
"It's a deal, sweetie," Aldo responded and went back to his dinner preparations.
