Billy paused for a brief moment and then continued to push his long, fat, shaft into her. Susie gave one long moan as his cock filled up her bowels, "Ooooooohhhhhh…" She loved the full feeling of being stuffed with Billy's cock. She relished inch after fat inch of his hard, thick, shaft sliding into her.
Becky watched as Billy's cock slowly slid in until his heavy balls rested against her ass. "Holy shit! Where did it all go!" she exclaimed.
Becky watched mesmerized as her brother began to slowly pull his shaft out of Susie's ass. She watched inch after inch slide out, until she saw Billy's thick, flared, cock-head once again appear, as if trying to escape. Billy quickly pushed it back in, widening Susie's sphincter. Her ass ring gripped it tightly and Billy pushed it back in again. Becky watched as Susie's hungry ass devoured the firm, thick, flesh.
"Oh fuck, am I so horny!" Becky said, and quickly unbuttoned her blouse, squeezing her naked titties. She slipped on hand under her skirt and began rubbing her naked, wet pussy. She got on her knees behind Billy and watched mesmerized, as her brother's cock slid back in, then out, of Susie's ass. Becky began rubbing her pussy harder and pressed her naked tits against her brother's back. She moaned into her brother's ear. "Fuck her, Billy, fuck her ass-hole good!"
"Ah, Beck, if I blur my eyes just right, it is almost like I'm fucking you. Oh, the cum loads I've jacked off, thinking about fucking you in this dress! I would dream that you came home drunk and horny and you would see my hard cock and want to fuck me.
"If I had known what a cock you had, little brother, I would have fucked your nuts off a long time ago," Becky said huskily into Billy's ear.
"Tell me, sis," Billy moaned, "Tell me how you would have fucked my nuts off!"
Becky pinched her clit. "If I'd had seen your cock, Billy, I would have said, 'Oh little brother, what a big cock you have!'" Becky whispered. They both watched his cock slide in and out of Susie's ass. Wearing Becky's dress, both brother and sister were imagining they were fucking each other – at a time when they were both younger and more innocent.
"Did I make you horny when I flashed my panties at you, brother? I'm sorry; let me make it up to you. Fuck me, Billy, fuck me while I wear my little-black-I'm-getting-cock-tonight-dress!"
"Oh, you slut, Becky," Billy breathed. "I'm going to fuck your tight little ass hard!" Billy began to fuck Susie harder, making her moan out loud.
"Ahh, Billy!" Susie groaned. "Take it easy back there! I told you my hole hasn't healed all the way from the last time!" She began to grunt, "Ugh, ugh, ugh" with each thrust.
Brother and sister ignored her pleas. "Fuck me, Billy," Becky cried, "Fuck me harder, I like to be fucked really, really, HARD!" She worked her clit and plunged her fingers into her wet fuck-hole. 'Too, bad for Jeffry', she thought, 'The little queer is going to get a hard pounding.' It was how Becky liked it, after all.
Billy began to slam his cock into Susie's ass. Becky worked her clit harder, watching her brother's huge cock pounding into Susie's little ass hole. It was so dirty and so exciting! It was too much - she began to orgasm. "I'm cumming, Billy, I'm cumming. Fuck meeeee-eee!" Her cunt rocked, her thighs quivered as she dug her fingers deep into her moist void. Pinching her clit and clamping her legs together, she fell sideways onto the bed, breathing heavily as her orgasm rocked her.
Billy felt the cum rising up in his balls, spurred on by his sister's moans. He pulled his cock almost out of Susie's ass and slammed it back in again, then again and again. He could feel Susie's ass pulling the cum from his nuts forcefully up through his shaft. He exploded in a glorious orgasm. "Take my cum, sis, take my fucking cum!" Rope after rope of sticky sperm blasted into Susie's bowels. "Ugh…, ugh…, Ugh…," Billy grunted as he came.
Susie moaned and also grunted; first from the hot cum load she felt exploding within her and then from the hard pounding her poor ass-hole was taking. Counting every thrust, she finally sighed in relief, knowing the abuse her sore boi-pussy was taking was almost at an end.
"Ahhh," Billy moaned, giving Susie a few final thrusts and then pulled his fat, slimy, cock from Susie's ass. He fell back upon the bed and lay next to his sister. Becky looked at her brother's cock, streaked pink with blood, lube, and cum.
Susie felt sweet relief as her gaping hole was finally free from Billy's red-hot poker. Although her sissy-clit was still hard and dripping pre-cum when she fell upon the bed.
They all panted heavily, catching their breaths.
"Well," Billy said, "What do you want to do next?"
Susie moaned, wanting to rest.
"I think I want my asshole fucked now," said Becky. She loved watching Susie get fucked, and even though Billy was rough with Susie, she knew Susie loved it, so she told herself. Becky really wanted to try ass-fucking too. After all, she loved to play with her ass-hole while she fucked herself with her dildo, and once she tried to fuck her ass with it, but it had hurt too much. She was ready to try again.
"All right!" Billy exclaimed. "Susie, get over here and suck my shitty cock until it is hard again!" He couldn't wait to fuck his sister's ass.
"Fuck off, Billy!" Becky said. "You are not showing that monster up my ass. Not yet anyway, if EVER!" Becky sat up and looked at Susie. Becky knew she had to have something smaller in her ass to start with. She looked at Susie lying on the bed, her hard clitty dripping with pre-cum.
"Do you want to fuck my ass, Susie?" Becky asked.
"Can I Beck?" Susie asked, not believing what she was hearing, "Really?" This was very exciting for her!
"You betcha, bitch!" Becky said, smiling. "You can even pretend you are fucking Billy, if you want."
"Aw, you sick fucks!" Billy exclaimed. "What did you have to say that for? Gross!" Billy turned left the room in disgust and went to wash his cock.
"Come on, Susie," Becky said, getting up on all fours and slapping her ass. "Fuck my asshole like Billy fucked yours." Becky added, "Just make sure you lube me up good and go easy on me!" She added, "At first, anyway." Becky wondered if she would enjoy a hard pounding in her ass like the same way she loved getting her pussy fucked.
Susie positioned herself behind Becky shaking with pleasure. Her small cock was hard and dripping. "Spread your ass for me, Beck, I can't see your hole." Becky's beautiful, wet cunt was visible to Susie, but her tight ass-hole was hidden by her ample, pale, cheeks.
"Ok, lover," Becky said. She laid her head on the bed and reached behind, spreading herself with both hands. Her tight ass-hole was totally exposed.
