Over the next few days, Grant could feel a tension between them. Paula was doing her best to push any idea of what had happened that night behind her. She didn’t want to have these thoughts about him. She couldn’t tell whether he was doing things deliberately or if it was her mind playing tricks on her. She started noticing Grant wearing his towel much more before and after he would go for a shower. He seemed to be in the kitchen and living room much more often in just his boxer shorts.

And of course, this was no coincidence at all. Grant was now fully flaunting himself around her Paula. Knowing that she had stopped to listen in on him and Anna the other night gave him this new air of confidence around her. He felt like he was teasing her and he loved being in control.

A few nights later, Paula was wearing some tight gym leggings that she usually wore around the house. She knew Grant had a thing for leggings as he’d said it enough times. As they were sitting in the living room after dinner, Paula went to clear the plates, Grant commented “Ohh Paula, those leggings are looking goooood…” he said it in a half joking way but also in a slightly flirty way. Anna turned to him and said “Do you mind not creeping on my sister please?!?” Also in a joking way. Grant replied “What? I’m just complimenting your sister on how good she looks, plus you know I’m a sucker for a girl in some gym leggings..”. Paula laughed nervously and thanked him and then went straight into the kitchen. She had butterflies and she could feel herself getting wet. She felt so conflicted.

The kitchen door opened and it was Grant, he came in and brushed past her to grab a glass from the shelf. He knew exactly what he was doing and she could feel his bulge just on the edge of her leg. He stopped and looked at him, she looked him in the eye and gave him a half ‘what the fuck are you doing look’. She looked down at his bulge now less than an inch from her leg and looked back at him. He looked at her and calmly whispered “There’s another show tonight if you want to listen in again…”.

Paula broke her gaze from him and immediately turned away. Grant smiled at her and acted as if nothing had happened.

Later that evening after one of the episodes of whatever series they were watching finished, Grant declared he was heading off to the bedroom. He gave Anna a kiss and whispered not to be long and then wished Paula a good night…

When Anna came to the room, he grabbed her and pushed her up against the wall and put his hand over her mouth “Shhhh I want to fuck you hard tonight but we can’t let Paula hear us…”. Anna began to kiss him back, half protesting but as soon as he began to kiss her neck and move his hands over her body and grab her by the waist, she couldn’t resist him. “Remember, your my dirty little free use slut that I can have whenever I want..” She could feel his finger sliding inside her tight wet pussy.

He pushed her on the bed and as she was getting herself into position, Grant opened the door a bit wider this time so Paula would be able to see in the room if she wanted to. It also meant that Grant would be able to see her if she did stop.

He grabbed Anna’s legs and lifted them up as he buried his face into her pussy. He licked her all over. Diving his tongue deep into her pussy and then running it over her clit and down to her tight little ass hole. “Do you like it when I like you here baby?” Anna would reply “Yes Daddy..”

He slowly teased her tight little pussy with his finger as he circled her clit with his tongue, then he slid the first finger in and felt her clench around it. He was working her up slowly building her close and then easing off.

Paula switched everything off in the living room. When she shut the TV off she thought she heard the sound of moan from her sister. Her heart began to pound again, she knew exactly what was happening. And she knew exactly what was going to happen. She didn’t want to but she cousins resist.

She walked out of the living room into the dark hallway to see her sisters bedroom door almost half open. Her heart was racing. She was shaking. She tiptoed towards the door and she could hear the silenced muffles of moans, fingering and the sloppy sound of someone getting head.

She crept closer slowly peered through the door opening to see her sister lying on her back with Grant on all fours between her legs licking and fingering her. She wanted to look away but she couldn’t. The way the light hit both of their bodies, the noises coming from them both, she could hear Grant moaning with pleasure just from the taste of Anna’s juices, she could hear how wet Anna was from Grants fingers moving in and our of her and she could see and hear just how much pleasure he was giving her.

Grant looked up and saw the dark silhouette of Paula standing peering in through the door. She froze. She couldn’t believe he had seen her. FUUUCK what’s he going to do?! She thought. But she didn’t move. And Grant just gave her a smile. He looked right into her eyes and moved up on to his knees and began to finger Anna harder and faster. His 2 fingers now pounding her pussy. She was gasping and moaning into a pillow to muffle her moans. Grant could see Paula’s face and could see her staring at what he was doing to her sister. He looked right at her and said “Do you like that you dirty little slut…?” Anna said “yes daddy” and Paula just looked at him straight in the eye and nodded her head.

Paula was caught like a rabbit in the headlights. She was under his spell now. Her pussy was dripping and throbbing. She needed to ease the pressure but she couldn’t. This was wrong. She was watching someone dominate her sister. “Is that good baby girl?” Grant said again, looking right at Paula, Paula nodded and almost whispered out loud “Yes daddy” as Anna said it.

“Im going to cum daddy…” Anna said which broke the spell between Grant and Paula. Grant increased his fingering even harder and began to stroke his cock. He moved his throbbing cock as close to Anna’s pussy as he could and as she let herself go, the stream of hot wet fluid that squirted from her cunt covered Grant’s hard cock and lower abdomen which triggered him to cum all over her. They were both soaked and covered in each others fluids.

Paula could smell the sex from the room now and could hardly control herself. She turned and made he way to the bathroom, shut the door, turned on the shower and sat on the toilet. What the fuck was going on?! She couldn’t believe what was happening. She cold feel the cold sticky mess she had left in her own panties. She wriggled out of her gym leggings and could see the slimy mess her dripping pussy had left on the black thong she had worn under the leggings.

She jumped in the shower and let the water run over her body. All f her senses felt heightened, she could feel her nippled getting harder and as hard as she tried, she couldn’t keep her hands away from herself. Eventually, she gave in and moved the shower head her body and let the water shoot over her labia. She needed a release. She needed to let go. But she couldn’t get the images of Grants hard cock shooting a hot sticky load all over her sister. She imagines what it would feel like covering her.

Her and her ex husband hadn’t had much of a sex life. But she can remember the times when he would pull out of her and shoot his load over her body. She loved the feeling of hot cum hitting her body. She loved Seeing it oozing out of a throbbing cock and splashing all over her skin.

She couldn’t control herself anymore as she held the shower head tight against her cunt. The water was shooting up against her clit, into her pussy and she could feel it tickling her ass hole. She hitched one of her legs up on the side of the bath tub that she was standing in and began grinding her hips as she could feel herself cuming hard.

She went so weak at the knees, she nearly lost her footing. She didn’t know how loud she had been but she suddenly came too as she heard a knock on the bathroom door… “Paula are you going to be long in there?” It was Grant’s voice.

She was flustered She quickly shouted back “2 minutes Grant…” And rinsed her body, off. She jumped out the of the shower, grabbed a towel and wrapped herself in it. She was shaking. She opened the door and Grant was standing right in front of her in just a pair of boxers.

She froze in the doorway staring at him. He gave her a smile and just said “Cheers, I’m dying for a pee. You were quicker than I thought you’d be.” Just as she moved out of his way and he brushed past her, he whispered “Good girl” and he shut the door behind him. Paula ran to her room shut the door and collapsed on the bed.

Grant started to brush his teeth when something caught his eyes. Crumpled in the corner of the bathroom was Paula’s t-shirt and leggings. When he finished brushing, he went over to have a look and to his delight he could see Paulas nice little black thong inside the leggings.

He lifted them up to inspect them and quickly felt how damp they were. He opened them up and there on the inside he could see the mess she had left after watching the show he had put on for her earlier.

He lifted the panties to his face and could smell her scent from them. His cock instantly began to twitch. The thought of the mess she had made of herself from watching him and Anna had him hard as a rock. He put the the shower on so no one would suspect what he was up to and raised the panties to his nose and began stroking his hard cock and taking deep breaths of her horny slutty smell.

He closed his eyes and could picture her staring back at him as he was dominating her little sister. She was watching and getting off on what he was doing. He could feel himself building up and his cock started to drip some pre-cum, as he was about to blow his load, he lowered the panties to his cock and filled the thong with his hot spunk. He stood with the panties hanging off his hard cock and wiped the rest of his mess into the now socking wet thong.

He jumped in the shower, cleaned himself off in the shower, grabbed his towel and wrapped it round his waist. He picked up Paula’s clothes and left the bathroom, walked across the landing and knocked on Paula’s door.

Paula had be lying in a daze still in her towel on top of her bed. The cool air was giving her goosebumps but she liked the feeling. She couldn’t stop thinking about what had just happened that night.

The knock at the door startled her, she jumped up and asked “who is it??”

“It’s me Grant…?”

What the fuck did he want now??

“Just a minute..”??She quickly grabbed some pyjamas and threw them on. A white loose t0-shirt and a pair of loose shorts. She opened the door to see him standing there in his towel, still with some droplets of water on his torso. Fuck he was looking good.

He looked her up and down and said “feeling the cold..?” She looked confused and then he directed his gaze to her chest. Her nipples were rock hard and showing through her white t-shirt. She looked at him trying to look unimpressed.

“You left these in the bathroom…” He said as he handed the pile of clothes over to her. Paula went red and started to panic… Where were her panties? Had he seen them? She reached out for the clothes and he gave them to her. Then without breaking his glance, he said “Oh don’t forget these…” And handed her the thing separately. When she hurriedly grabbed it from his and, she suddenly noticed how wet it was.

Grant turned round and said “goodnight” then headed for his room.

She shut the door and looked in her hand at the crumpled wet thing. She could feel the cold slimy cum seeping through the thin fabric. She couldn’t believe what it was until she lifted it to her nose and smelled it. The unmistakable smell of fresh cum. Suddenly she realised what Grant had done.

She didn’t know what to do. She was stunned. She threw them onto the floor. She was disgusted. Who the fuck does he think he is? She was sp angry. But she was also so horny. this new naughty, slutty inner devil was raising her its head again. Every time she shut her eyes she could just picture him shooting his load into her panties the same way he had shot his hot sticky load all over her sister. She wanted his cum on her. She wanted to feel hit onto her skin.

She rubbed her fingers together, she could still feel the wetness of his cum that had transferred from her sodden panties onto her hand. She raised it back to her face and took another deep breath through her nose. Taking in his scent the same way Grant had done for het dirty slutty musk.

She reached to the panties on the floor, dropped her shorts and pulled the soiled thong back on. The coldness on her skin felt wrong and dirty but she didn’t care anymore. She was in full dirty little slut mode now. She was Grants dirty little slut with his cold cum mixing with her soppy pussy juices.

She grabbed one of the pillows on her bed, fluffed it up and bunched the duvet covers up. She straddled the pillow and began slowly humping the pillow. She could feel the wet fabric sliding over her pussy lips. She tried to add more pressure and forced more weight down on the pillow as she sped up the thrusting of her hips. The shame was turning into pure filth and she needed it. She needed to be a filthy little cum slut as her brother-in-laws cum mixed with her juices in her dirty wet thong. She was full humping the pillow imagining she was putting on her own show for Grant. She lifted her fingers to her nose and took in more of the smell of her and his sex juices mixed together. She could feel herself losing control. She was feeling the wave of pleasure coming over her whole body.

With her right hand up at her nose taking in the sex smell, she arched her back and grabbed her breasts through her t-shirt with her left hand as she jerked uncontrollably in orgasm. She could feel the hot slippy feeling as her juices gushed from her and through the gusset of the thong.

She collapsed on the bed. She didn’t even have the energy to take the panties off. What a dirty little slut she had become.
