There had been a late summer storm overnight with heavy wind and rain and, again, the tired old roof on my house had leaked. The weather cleared over the morning and I was now clambering over the tiles in the welcome sunshine with my tube of silicone sealant, searching out the newly cracked ones and trying to effect temporary repairs. What a way to spend a weekend! Six more months and I'll have saved enough money to get the whole place re-roofed. Goddamn my ex-wife! If she weren't bleeding me so much for support, I'd have had this done two years since. She was the one who, ten years ago last month ran off with her personal fitness coach, who dumped her five months later. And, thanks to a female judge with a feminist axe to grind at the divorce hearing, the cow has lived off me ever since!
I was working right up on the ridgeline when I noticed my next door neighbour, Arlene, set off in her car. It looked like she was off to the supermarket, which usually meant her being away for a couple of hours. She was a dark, trim widow in her late thirties who had two teenaged kids: Abby, who was almost twenty, and Chris, who was fifteen months younger than his sister. I knew from long experience that Arlene going out meant that a fight between Abby and Chris would start very soon. And I wasn't wrong - it took them less than five minutes to begin screaming and yelling. God, those kids hated each other!
I carried on looking for cracked tiles and spreading silicone around, when a sudden movement from next door caught my eye. I could see right into their lounge room through the big ranchslider that led out onto their patio. Chris was chasing Abby around the furniture, yelling at her. She was holding something small in her hand. It looked like a calculator. I guessed that she must have stolen it from her brother and he was chasing her to get it back. Eventually he caught up with his sister and threw her onto the floor up close to the glass door. Although he was the younger of the two of them, Chris was much bigger and stronger that she was.
They wrestled furiously for a few moments with neither of them gaining any advantage. Then Abby played one of those typical 'sister tricks' that girls play on their brothers when they want to stop them from taking something away: She pushed the calculator under the waist band of her baggy shorts and held it with both hands up against her crotch. Abby stuck her tongue out at Chris and pulled a face. I didn't have to be there to know she was saying in a singsong kind of voice, "You can't get it na-ow!" My kid sister used to do that to me all the time when we were young.
But by now Chris must have been damned mad, or maybe he was made of sterner stuff than I was at his age, because he shoved his hands up his sister's shorts leg and wrestled the object away from her. They fought furiously for a little while longer, with Abby biting Chris's fingers and screaming at the top of her lungs for him to "Give it back!" I could hear every word now and her language would have made a shearing gang blush.
Then suddenly, Abby gave up the contest, letting go of the prize so that Chris tumbled over. He fell with his head and shoulders across her slightly spread upper legs, holding the object up like a trophy and grinning like a maniac. Abby let loose another stream of invective at her brother, then dissolved into tears with her hands covering her face. Chris just laughed at her, revelling in his victory, then he bent over and bit his sister hard between the legs. Abby fetched him a mighty slap on the side of his head. I could 'feel' it from where I was. But Chris just rolled away from her laughing and then got to his feet and ran from the room holding his trophy above his head. Abby curled up in a ball on her side and sobbed her heart out.
I lay on my belly on the roof, full of sympathy, looking down at the weeping girl. I really liked Abby and usually took her side when these fights happened between her and her brother. That wasn't only because she was an exceptionally good-looking young chick, with firm little boobs, a tight ass and great legs, she was also much the nicer person of the two of them. Chris could be a mean little bastard when he wanted to be and I often wanted to whack him one at some of the things I heard him saying to his mother. But it wasn't my place to do that. At that moment, I would have given anything to take Abby in my arms to cuddle her, stroke her hair, and tell her everything would be all right.
After a few minutes Abby sat up and dried her eyes on the sleeve of her T-shirt. And then my heart almost stopped, because she pulled the leg of her shorts right up and shifted her panties to one side while she checked for damage where Chris had bitten her. I was a fair distance away, but I could still clearly see her faint dusting of dark pubic hairs and the luscious slit of her pussy between her legs. I instantly got a hard-on and had to adjust my cock in my pants to stop it breaking in half under the pressure. After a very brief examination, Abby covered herself again, much to my disappointment, and lay back down with her eyes closed. I carried on looking at her. I could have stayed there all day she was so gorgeous, but work eventually called again.
I was just about to cease my voyeurism to carry on with my repairs when I saw Abby move her hand and start to stroke her inner thigh up under the leg of her shorts. My hard-on returned with redoubled intensity as I watched her move it higher, until she was, clearly, inside her pants and fingering her pussy. At the same time she pushed her T-shirt and then her bra up her chest with her other hand and began stroking her breasts and pulling at her nipples. I couldn't help myself. I undid my zipper and pulled my rock hard cock out and started jerking myself off as I watched her masturbate.
Abby writhed her pelvis rhythmically. She now had both of her hands inside her pants, plunging her fingers deeper inside her pussy and working on her clit. Her chest was shaking and heaving with the rising intensity of the feelings she was engendering. I was fast approaching a climax too. I could feel my balls tightening in their sac and that familiar excruciating rise in tension in my scrotum that heralded a massive cum. Then I saw Chris come back into the room. When he saw what his sister was doing, he crept slowly up to stand beside her. Abby was too far-gone with pleasuring herself to notice anything much else by now. I stopped stroking my dick and just held it in my fist, waiting expectantly to see what would happen next.
Chris rubbed his crotch through his trousers. It was clear that, like me, he had a huge erection. Then, plucking up courage no doubt, he undid his pants, got his cock out, and started to jerk himself off as he watched Abby plunder her pussy with both hands. Jesus, he was pretty well hung for a kid his age! But quite inexperienced though, because in a very few seconds his whole body started twitching and long, pearly strings of jism began spurting out of his prick and splashing onto his sister's bare belly. Abby opened her eyes with a shriek. And when she saw that the source of the hot fluids splashing on her was her brother Chris, she tried to roll away from his sticky stream. But he followed her, making sure she got everything.
Abby aimed another stream of abuse at her brother, including a demand that he clean up his vile, sticky mess off of her. Surprisingly, Chris appeared to agree straight away, and kneeled down beside her and started to wipe her down with a handkerchief from his pocket. But the real reason for his altruism soon became apparent when he slid his hand under the waistband of her shorts and, judging by Abby's reaction, down into her knickers. She tried to fight him off, but his superior strength prevailed. And when his fingers found her soaking pussy she gave in and spread her legs wide, lifting her pelvis to his fingers as he entered her.
Chris' long soft dick was still hanging limply out of the front of his trousers. Abby gazed at it for a few moments while she ground her pussy ecstatically against his fingers. She had been close to cumming when Chris disturbed her and now she was returning rapidly to that peak. Tentatively, she reached out a hand to touch her brother's tool. It stirred under her fingers and started to harden again. Abby gripped it firmly and stroked it in her fist, rapidly bringing him back to a fully rampant erection. Chris thrust against her hand in time to the plunging motion of his fingers in her sex while Abby shook and writhed her pelvis and massaged her swollen nipples with her free hand.
Brother and sister were going to explode in and orgasmic frenzy very soon. And so was I, up on my roof, furiously pulling at my cock in time with their wild movements. Chris and I didn't quite make it, because Abby suddenly tore herself away from him and rolled onto her side with her hands pressed hard into her crotch. She was obviously cumming - and cumming very hard. I stopped rubbing and returned to holding my dick like I had been before. Chris just knelt and watched interestedly as his sister shuddered and trembled. His erection slackened slightly, but did not entirely collapse.
He gave her about six minutes; then he turned her onto her back again. He said something to her and gestured to his prick. Abby shook her head violently. Chris gestured to his prick again, obviously demanding that she do something with it. Abby shook her head again. I could see another fight brewing. Then, suddenly, Chris swung his leg across her so that he was kneeling astride her chest. He took his shaft in one hand and lifted Abby's head with the other. Holding her still he jammed the crown against her tightly closed lips. Abby shook her head again in protest. Chris banged her head on the floor and lifted her head up again. I heard his shout: "Suck it you horny bitch!" Abby shook her head again and was rewarded with another head- thump on the floor. After her third refusal Chris slapped her face hard, "You'll suck it you dirty cunt or I'll smack you around all day!"
