The black stone part 4. To understand this story, you really need to read previous stories.
The journey continues with more violence, strange sex and drifts into Incest.
Arriving at Marys house Mark was nervous, he hadn't seen his younger sister since she had married her husband Tony almost 5 years ago, he remembered how she had seemed so happy when she visited him in prison. Telling him she was getting married and moving to Hartlepool. As they knocked on the door of the small terraced house Mary ran up the side passage and excitedly hugged her brother. Eventually she let go and turned to Fiona, welcomed her and then ushered the pair into her house.
The house was sparsely furnished and Mark started to notice the bruise on Marys face and her shabby clothes, he asked where Tony was "oh he's at the football, he won't be home till later tonight". Fiona asked where the loo was and left the two siblings alone. Mark immediately asked Mary about the bruise on her face, looking pained she said that she had walked into a door frame a few days earlier.
Mark didn't believe her and grabbed her arm to make her look at him, she knew better than to try and lie to her brother. He had always been able to see right through her. She broke down in tears as she confessed that Tony sometimes knocked her about. Fiona returned from the toilet and seeing the state of Mary looked at Mark wondering what the hell was going on.
Mark had never met Tony so quietly asked for a picture and where he was likely to be now. Looking at the clock Mary said he will be in the Star and Garter on the Riverside until about 2pm. Asking Fiona to look after her he left the house to find the pub. As he walked in the pub he caught sight of Tony almost straight away, he was a big man with an even bigger mouth.
As he looked on he saw him stroking the barmaid's tits through her blouse and noted that she was leaning into him. At that moment the landlord rang last orders and the pub began to empty as people filed off to the Match. Mark watched as the women got her coat and Tony and her started to leave the pub.
Following them into the street and around the corner into a small industrial estate he crossed the street just in time to see them walk between some warehouses. He crossed the street again and cautiously walked along the road until he could see down the narrow alleyway. As he watched he saw Tony give the women some money and she knelt as he got his cock out.
When she had sucked his cock for a while he pulled her up, bent her over and proceeded to fuck her doggy style. Marks temper exploded. Running down the alley he caught the women in the side of her face with his knee and as she sagged to the floor turned to face Tony.
With his rage erupting he started to hit him stopping just long enough to hiss in his ear that he was Marys brother and he was going to beat him senseless for hitting her. Tony's eyes went wide with fear and then he started to whimper as Mark hit him in all the right places as only a true sadist can.
Soon Tony was screaming in pain as Marks powerful punches rained down on his body. Mark waited for the pain to really bite on Tony's tortured body. As Tony hovered on the edge of conciseness Mark left him in no doubt that worse would follow if he ever saw him again.
Turning to the barmaid he pulled her up by her hair, forcing her over a low wall. Dragging his stiffening cock out he wiped it around her gaping pink slit. Ramming his cock into her as hard as he could, her cunt flooded as she rammed back onto him forcing his 9" into her old, worn out cunt. Mark grabbed her hips and continued to ram into her, feeling her cunt contract as her orgasm racked her body he blew his load deep inside her.
As Mark warned her to keep her mouth shut about Tony she shrugged "no problem any time you need a fuck come see me". Picking up her panties she said, "I never liked that fat cunt anyway" and walked back up the alleyway.
Mark checked his clothes and noticed his jacket had blood stains on it, cursing he took it off, folded it up and started to walk back to the house. As he entered the small house the lounge was empty as was the kitchen and garden. A little concerned he decided to look upstairs as he got to the landing he heard muffled giggling and soft feminine conversation.
He looked around the door and saw Mary on her back legs splayed wide with Fiona on all fours lapping at her pussy. His cock was instantly raging hard and he loosened his belt as he walked behind Fiona. His sister had her eyes closed and he noticed that she had a great pair of tits with long rock-hard nipples.
Fiona knowing, he was there waggled her arse invitingly. Mark released his rock-hard cock and aimed it at her sopping hole. He plunged in to her beautifully tight cunt and slowly started to stroke in and out. Mary felt the bed shift and opened her eyes, when she saw Mark she tried to cover her tits but then started to giggle as she realised the futility and was soon starting to cum. Pushing Fiona's head into her pussy as she did.
Fiona moved forward and started to kiss Mary causing Mark to grunt in frustration as his cock was pulled from her cunt, "don't worry we will take care of you soon" she said. Fiona started whispering to Mary as her hand got busy between the older women's legs. After a brief exchange of whispered conversation Mary nodded in agreement.
As the two women changed places Mark was confronted with his sisters hairy sopping wet cunt, it looked better than Mark had ever imagined, Mary looked over her shoulder and said, "I hope you enjoy me" then turned and got busy on Fiona's cunt. As Mark pushed into his sister's cunt she raised her head and said "wow, give me chance to get used to that you are huge".
Smiling to himself Mark made gentle rocking motions until he was balls deep in his sister's body, she was very tight but soaking wet. He moved slowly in and out causing her to moan in pleasure and he could feel her cunt walls start to grip him as her orgasm built. Mary continued to lick Fiona and soon she had a crashing orgasm.
Mark could feel Mary was cumming as her cunt squeezed her brothers cock. Luxuriating in her silken smoothness Mark took his time. As Mary was cresting to her 4th orgasm Mark exploded inside of her sending rope after rope of thick white spunk into his sisters clinging cunt. Collapsing onto the bed both women cuddled into Mark as they fell asleep.
Mark awoke to find both women working on his cock and was soon iron hard. Fiona straddled him and took his cock deep inside her and motioned to Mary who straddled Marks head lowering her pussy so he could lap at her free-flowing juice.
The girls kissed and tweaked each other's nipples Fiona was the first to come and showered his cock with pussy juice. The girls changed position and he was again buried up to his balls in his sister's sweet cunt. He had, had so much sex in the last few days but he banged his sister hard.
Mary whimpered with pleasure as his cock reached deeper than any mans. When Mark felt Mary coming again his cock swelled and he dumped another huge load into her. Rolling off him Mary started 69 with Fiona lapping up the mixture of Marks cum and Marys cunt juice.
