The door slammed upstairs, and Justine hurriedly removed the pins from her own breasts. A voice called out, “Where are you, Justine?”
“We’re down here, Justin. Auntie Pru and I are having a little tete a tete.”
Justin came down the stairs into the den and saw his naked sister pirouette to face him, with beads of blood oozing from her mammaries. A look of horror came over his aunt’s face as her nephew saw the scene, and looked away as his eyes traveled up and down her figure, criss-crossed with angry, red trails, and punctured by many small needles. He put down his briefcase and sat on the arm of the couch. “Well, this is a hot scene. Mind if I watch?”
Justine walked over to her brother. “I’ll let you do more than that,” she said as she walked over to him to embrace him and bury her open mouth in his. The long French kiss brought moans of outrage from the older woman. They broke the kiss and Justine reached to fondle Justin’s crotch as she looked at the bound woman. “I’ll bet you’re horrified by this, aren’t you?” The older woman nodded her head gravely. “Justin and I have been lovers for a long time: we bathed together until we were teenagers. I took his virginity a couple of weeks before I left for Europe, and we’ve fucked like rabbits every day since I’ve come back. We know each other’s bodies very well, Auntie Pru. I’m the best cocksucker and the best fuck he’s ever had, and his dick is my dream come true. I wish I’d given him the best handjob he ever had, but he says the ones Mom gave him are still best. Still a goal, still something to work on” Fresh tears rained down Prudence’s face.
Justin turned to lick his sister’s ear, and said, “I feel up to a nice game of darts. What do you say?”
“That sounds like a splendid idea, baby brother. Pity we don’t have a dart board around?”
“I think that Auntie Pru would be happy to offer us her huge ass as a dartboard, wouldn’t you?”
“I’m sure she would. Here’s a box of projectiles that I think will work just fine. But little brother, you’re overdressed here. Let me loosen your belt.” Justine knelt before him to unbuckle his belt and undo his fly. As she pulled his pants off, she took his limp penis in her mouth, licking and savoring it broadly for Prudence to see as she unbuttoned his shirt for him to pull off. Prudence shuddered as she watched her niece’s mouth hungrily devour her brother’s meat, and her nephew’s rapt expression as his sister serviced him. His shirt went back over his shoulders and his sister curtailed her oral attentions. Taking his hand, she picked up the box and led him around to the other side, out of Prudence’s sight.
The older woman jerked and jiggled as the needles hit the target, bleating through the duct tape over her mouth. The young people carried on gleefully, laughing and giggling as they flicked the projectiles to bury themselves in the huge mound of flesh. Beads of blood trickled from some of the punctures. A couple went down the leg and one hit directly where the hips met the lower back, drawing a squeal. Prudence’s backside now looked like a pincushion
Justine stood in front of her aunt once again. “What’s the worst thing you don’t want to see? Well, the worst thing we could do right here, right now? I think we’ve done enough to hurt you physically, and it’s been really hot for us. Or have we? Let me get out another couple of toys.” She reached into the drawer of an end table, pulling out a wicked looking set of clamps on a chain and a riding crop. “We’ve haven’t gotten to these yet. You’ve played with these before Auntie Pru, haven’t you?” Prudence nodded weakly. Justine traced circles on her right breast with the closed clamp, while her aunt looked on. “Your tits look busy enough, though. What if I attached these to myself?” Her nubs were fully erect, and she placed the clover clamp on the right one, then rubbed the left one with the other. “You know how these feel. You know what happens to them when they’re pulled or yanked or jiggled.” Prudence nodded. Justine teased her left bud a little, then set the other clamp on it. “I’m going to prove something else to you, Auntie Pru. I’m not only the best domme you’ve ever had; I’m a better painslut than you are. You’ve done this for him; I’m going to show you that I can take it, too. Justin, come around here.”
Justin came around from behind his aunt’s field of view, grinning manically. He took the whip from his sister and moved around behind her, caressing her body from behind with his huge dick rubbing her crotch from behind, Justine reached around to stroke his erection to line it up with her cunt. “Justin, whip me while you fuck me doggy style. Let’s both watch Auntie Pru as I prove to her who’s in control here, who can take dish out the most and who can take the most. Slip your precious pecker up my twat, baby bro.” As she bent over, Justine took the center of the chain between her breasts and held them in her teeth. Justin gave her buttocks a light couple of taps as he aligned his member for penetration, then entered her with one thrust, causing her head to jerk up in bliss, pulling the clamps tighter.
Prudence could not believe what she was seeing. She looked on in horrified fascination as Justin drove his cock deeply into Justine’s cunt from behind, tapping her behind alternating sides. Justine closed her eyes in bliss and winced slightly at each blow, pulled her clamps a little tighter. “How can that do that?” Prudence thought, “how can they so casually fuck right in front of me? My God, he’s hitting her butt harder and harder with each stroke, and her head is all over the place. Her nipples must be on fire right now. They’ve done this before, they’ve done this regularly. How awful. I thought I was bad. How lovely she looks like that. She’s going to explode soon, I can see it. I’m over here just watching, can’t do anything. Can’t stand it, can’t stand it. So near and yet so far. What kind of parents did they have to let them end up like this? O my God, how can this happen?” Right before climaxing, Justine spit the chain out of her mouth to buck wildly against Justin and writhe wildly before her orgasm sent her jaw quivering and her body shaking. It seemed to go on forever before she half-shifted, half-fell to the adjoining sofa, her brother falling out of her with his dick standing out its full ten inches, glistening with her glaze.
Justin came over wordlessly with a clean white towel and started removing the pins from Prudence’s breasts, putting them on a ornamental plate on the table in front of him. He blotted any bleeding, then moved around to start removing the ones in from her backside. Gentle touches pacified her somewhat, until with an effort he picked up her lower torso and put her feet on an ottoman nearby, so she was bent over with her wrists still cuffed above her, with her pelvis roughly at the same level as Justin’s. Justine looked up at her, then at her brother and nodded her head. He put his hand up his aunt’s canyon; despite everything she had been through her crotch was soaked and her vagina slick.
“What shall I do with her?” Justin asked.
Justine snuggled herself on the sofa with her eyes closed. “I’m done for now. If you want to do something about your hard-on, you’d better fuck her. Right now.” With a sudden thrust, he penetrated his aunt’s cunt fully and began pumping her with slow strokes, accelerating gradually. Justine looked bored for moment, then stood in front of Prudence staring at her. Justin reached around to squeeze Prudence’s huge jugs as he enthusiastically pistoned her, and she moaned through the tape still stuck to her mouth. With a sudden movement, Justine ripped the tape off in one motion. Prudence let loose a scream.
“Having fun yet, Auntie Pru?”
Prudence shook her head. “You two are out of hand. I’m appalled that you two are sleeping together.”
“What about both of us sleeping with you? How is that better? You seem to be enjoying Justin’s donkey dick filling your cunt right now. You’re bucking back against his thrusts pretty well. How is it wrong for us and right for you?”
Prudence winced and sighed. “It isn’t right. At least I know it’s not right that I fucked you both. I couldn’t help myself: I’m so lonely, and you’re so young and vibrant. Ah,ah,ah. You don’t know what these years are like, or maybe you will, sweetheart. No one will want to stay with an arrogant bitch like you. You’ll end up a lonesome old woman, just like me.”
“Arrogant bitch. I’m never going to be a loser like you,” Justine screamed, and reached out to twist Prudence’s pained nipples. “I can dish it out better than you and I can take it better than you. You’re nothing, Auntie Pru, and ugly, old bag with nothing. You’re not the best at anything. I bet that I can beat you at a torture contest any time, any place.”
Prudence started losing control as Justin was approaching his liquid outburst. Justine slapped Prudence’s tits with her open hands, one after the other as her aunt’s legs started getting weak and the orgasm made her a shuddering mountain that threatened to come unglued. Justin yelled as he pumped his sperm deep into his aunt’s uterus once again for a full four minutes before he subsided and pulled away. When he regained control, he reached up and unstrapped his aunt’s wrists, directing her to sit on the couch nearest to her.
Justin came around to where his sister stood face to face with their aunt. The two young people towered over their aunt, who was still shaking and oozing from dozens of little punctures. He tapped his sister on the shoulder: “Hey, Justine. Do me a favor and lick this off, would you? It’s real sensitive right now and your tongue on it would send me into orbit.
