Shuddering to the thrills of Jenny's cuntlapping, Cheryl listened to the noise of her sister's mouth working between her spread legs, too. Hearing the sounds of having her pussy so lovingly licked made her all the hotter. She felt Doug's cock bucking more and more as it slid through her rolling asshole, so she knew that those big balls bouncing between her thighs and on the back of her drippy cunt would soon shoot their cum up her wriggling butt. She noticed Doug's hand wasn't holding her left knee out anymore. It wasn't needed. She was holding her hot crotch open for her sister's good sucking all on her own.
Doug's arm even relaxed its grip at her waist. Then the hand softened and slid up over her breasts, massaging and rolling them, cupping them and squeezing them gently, fast-thumbing their buzzing nipples with flipping strokes. Cheryl bounced her asshole around on the boy's stiff cock ramming in and out of her stretched rectum, shivering to the tit-teasing fingers and Jenny's tongue whipping far up her goo-soaked pussyhole, too, fluttering and flapping against the skin of her unbroken cherry. Between times, the tongue came licking back up over her sparking clit and batted away at it.
Jenny still fucked those two fingers into Cheryl's virgin pussy as far as the cherry inside allowed her to shove. When she saw that Cheryl was very close to cumming she spent most of her time sucking right on the blonde's clit.
Bucking her ass helplessly as the rising shocks of pleasure hit her from two directions, her belly jerking and knotting harder, Cheryl grunted and twisted between her pussy-licking sister and the butt-fucking Doug Brill. Her eyes rolled and her breathing came hard and rasping. Wonderful feelings flashed all through her body that she couldn't believe. Even the thickly prodding cock up her ass felt unbelievably good.
"Oh! OH! My cunt! My ass! My tits! Oh, God! Eat me, Jenny! MMMM! Fuck my ass, Doug! AAAHHH! I'm going to cum any second!" Cheryl exclaimed.
"So am I!" Doug panted in her ear, still easy-rolling her breasts for her. "Right up your ass, too!"
The foggy-eyed blonde was nothing but shivers and fuck-thrills. Her tits swelled out, feeling throbby and stiff-nippled. She looked down and saw that her sister still had her left hand at her own gooey cunt, whacking herself fast there. Jenny was shivering, glassy-eyed from pleasing herself, but was also eating into Cheryl's blonde pussy and pleasing it.
"Jesus!" Doug said, grunting suddenly and shoving his cock especially deep up the blonde's ass. "I'm gonna cum, Cheryl, baby!"
Jenny echoed her boyfriend from her cunt-sucking crouch below.
"Oooooo, so am I, Doug babes! Dose my sis's asshole with hot jizz!"
Hearing Jenny's obscene words to Doug, feeling the rams and slides of the boy's cock up her butt and twitching to Jenny's wild sucking of her cunt, all pushed the blonde into orgasm. Stiff and vibrating all over with the hot thrills of cumming, she yelled out her joy.
"Oh, Jenny! I am cumming! Suck me! Suck me more!" she begged.
She just let her cunt gush its juices into her sister's drinking mouth, watching her fast-whack her own dribbly slot. Then her rectum pulsed and stretched more as Doug's dick bucked hard in her asshole and began spurting its heavy sperm up there.
"Aaaaggghhh!" Doug groaned. "Take my load, Cheryl! What a tight asshole you have! Take my cum! Uuuuuhhh! There!"
The jizz-gobs flew up through her guts, burning and thrilling her. Her pussy spasmed and gushed off more into Jenny's working mouth. She rattled and blew harder than she had in her bedroom, whacking off the night before. Her strength drained away in the cum-shocks. Her crotch and openly drooling gash pushed forward and squished sloshily around her young sister's cheeks as her knees buckled from the jerking climax.
Cheryl's cunt convulsed on Jenny's lips and chin as she sagged down in Doug Brill's arms and Jenny licked faster in her gushing split. Her asshole clutched and fluttered around Doug's shooting prick until his balls were totally emptied. She slouched down more when he weakened and lost his hold on her, and she tilted off to one side of the john. Her pushing pussy knocked Jenny off balance and the young brunette flopped to her back on the bathroom floor. She noticed that Jenny's rubbing right hand at her own cunt didn't lose a beat. Her brunette sister lost her sappy load of pussy-cum there on the floor, legs flopping as she groaned and shuddered off.
The blonde watched her cunt-whacking sister gush off hard, feeling herself dropping toward the floor faster as Doug's cum-weakened arms failed to keep her up. She felt his prick pop out of her cummy ass-door, quivering when a flood of jism followed the cock and dripped down her left thigh's inner side. Gasping, she fell toward the right and that foot slid off the john's seat.
Cheryl grabbed the shower curtain on the way down, not able to hold on, but breaking her fall. She landed on top of Jenny's nearly naked body, face to face with her sister as they stared into each other's eyes.
