"Oooooo, that would be soooo wrong!" Julie purred as she snaked her own hand down onto Liz's wet pussy. Liz gave her boner a strong tug and sighed as Julie fingered her slick slit. Julie's dipped her fingers lower and felt Jim's hand. She soon felt that Jim had a finger up his sister's butthole, pumping it in and out. "Ummm, Lizzie, how does that feel, baby?"
"One of you fuck me," Liz whined. "I don't care who goes first…or where." "I want to see you fuck her ass, Jim," Julie said. "You'll love it…she's got a nice tight tail."
Liz partially rolled on her back, toward her brother. Julie could see her pretty face simmering with excitement at the thought of being done backdoor while she watched.
"There's some lube in this stand," she said, her right hand pointing past her head to the nightstand behind Julie. Jim pulled his hand from her ass and jumped off the bed, his large prick bobbing in front of him. He moved to the stand and opened it up, looking for the lubricant that would make it easier for him to get his fat cock up his sister's asshole.
Julie moved lower over Liz's twisted form and smoothed the hair from her face and gave her tender kiss.
"Mmmm, Jules, look what you started," Liz sighed as she released her cock and ran the hand up to cup her tit. She stretched like a cat, shoving her hips against Julie, pressing her pussy into Julie's swirling fingers.
"I knew you'd love it…you're a little nympho!' Julie said before kissing her strongly, Frenching her as the bed dipped slightly with Jim's return.
Jim, back on his knees on the bed, looked down on the two female forms kissing; correction — female-like forms, he reminded himself. In his hand was a tube of KY jelly; he'd heard of the stuff but never used it before. Now he was going to get a chance.
Julie broke their kiss and looked up at him, her eyes falling and staying on his outthrust erection. He remembered that she considered herself a female. She was looking him like a female.
'I bet she'd like to suck my dick,' Jim realized. Part of him railed against the idea; she'd used to be a guy somewhere back in her past after all. But that face, those lips, those fucking tits!
"Your brother is back and he looks like he can't wait…let's lay you out this way…" Julie positioned his sister on her stomach longways in the center of the bed and she knelt by his sister's bottom. Beth twisted her torso around and looked back at the two of them.
"Jules, why don't I lie on my back and pull my legs back? I like it that way better."
"No, baby," Julie said, rubbing her back, "I want him to do you this way." She motioned for him to get in position and held her hand out for the jelly.
"We'll do it that way tonight," Jim promised his sister as he moved between Beth's spread legs, handing her the tube. He loved the sight of his sister's lush body laying before him — the firm back of her thighs, the half-moon buns of her ass, the trace of her spine down the middle of her athletic back. He couldn't wait to lay on top of her and fuck her tight rear end.
He watched Julie squirt a big glob of the jelly on two of her fingers and his sister actually reached back with her left hand and pulled her asscheeks open!
"Don't skimp on that lube," she said to Julie. Then to him, "I'm going to need it for that big thing," she complimented him.
"Here you go," Julie said and she smeared the glob of jelly on Beth's pink asshole. Jim jacked himself slowly as he watched Julie stick one, two and then finally three lubricated fingers in Beth's backdoor opening, much to Beth's delight.
"Mmmmmmmm..mmmmmmmmm….oh, yeah….now, do his dick," his sister encouraged Julie. Julie squirted another glob of the KY into her hand and quickly wrapped her hand around his jutting manhood before he could express any reservations.
"Let's get your dick nice and slimy," Julie said huskily. Her hand corkscrewed up and down his shaft several times, smearing the jelly all over, and then she wiped her palm on the head, leaving it coated as well. Julie tossed the tube away and wiped her palm across Beth's bottom several times before giving it a whack.
"Lift that ass up for your brother!" Julie ordered his sister and she did, raising her bottom like a bitch in heat, keeping her shoulders on the bed. Julie shooed Beth's hand away and used her own hands to spread his sister's gorgeous tush.
"OK, Big Jim. Come and get it…I want you to stick that slowly up her ass!" Julie said hotly.
Jim scooted closer, using his left hand to steady his sister's bottom and the right to direct his glistening cocktip against her puckered anus. He pushed against it and the skin around her asshole dimpled inward as he exerted strong pressure.
"That's it…keep pushing..it'll pop in," Julie coached him. He pressed harder still and felt his glans bust through her tight sphincter ring.
"Aaaww, shit, it's in!" he exclaimed excitedly. The skin around her asshole seemed to ride a little ways up his shaft as it sprang back to near its original shape.
"Mmmmmmmmm…God, it feels huge!" Beth grunted. "Go slow!" "Just stay still," Julie said, "Let her get used to it….this is quite a sight, Lizzie…your brother's dick sticking in your ass." Julie ran her fingers around the stuffed rim of his sister's shithole and Beth mmmmmmmmmed somemore. Jim released his dick and ran his right hand under to play with his sister's bare pussy. Her mmmmmms turned to aaahhhhhhhhhs and she raised herself up on her hands into the classic dogstyle position.
"Come on…push it in!" she said, looking over her shoulder at him. Jim moved both hands around her waist and pulled her back at him as he leaned into her. Two inches of his dick disappeared into her tight bowels. "Ooooowww….no, its OK, more, keep pushing," Beth said through gritted teeth, her eyes closed in obvious discomfort. Jim wasn't sure he wanted to if it was going to hurt her but his sister humped her bottom back at him and another inch was gulped up by her gloryhole.
"Oh, Lizzie! God, it looks so hot…that's it, Jim…shove it in her…there it goes…more…it's getting easier now…look at her ass suck it in!" Julie did the play-by-play of the beginning of their incestuous assfuck.
Jim had almost all of his cock up Beth's gripping anal grotto and decided that it was enough. He began pulling it out, fascinated by the way the inner lining of her ass clung to his greased pole. He extracted three inches and then slowly pressed it back in.
"Yeeeeaah, fuck her ass…it's tight but it'll loosen…then you can really give it to her," Julie promised and sure enough the next push back in went a little easier.
"Fuck, you're tight, Beth!…aaahh, yeah…I'm fucking my sister's asshole! Shit, it feels great!" he gushed, knowing everyone else in the room was enjoying the whole scene.
"Ooooooow…mmmmmmmmmmm….mmmmmmmm," Elizabeth vocalized every thrust of Jim's wide impaling manhood as it moved in and out of her derriere. The initial pain had faded to only discomfort and that was even beginning to disappear; in it's place would be left a wonderful kinky fullness, if it was anything like her anal sex with Julie.
"Oh yeah, Beth…move that ass back at me!" her brother called and she realized she had begun to move with him, working her butt back at him as he pushed in. The feeling was wild — getting fucked in the ass by her hunky little brother while her he/she lover watched. Her pussy was dripping with juice and it was going to get juicier when she got off. All anyone had to do was finger her powderkeg clit and she'd go off.
"Fuck me, Jim…do it harder," she groaned and her obedient sibling socked his cock in harder, making her tits sway and her mouth fall open. She felt Julie moving up near her shoulders and she turned her head the other way, toward Julie. Julie bent at the waist to kiss her again and Elizabeth felt Julie's right hand moving under to massage her dangling breasts. Elizabeth mewed in her mouth as she pinched one of her hard nipples and her brother humped his hot spike up her ass again.
