Weekend of fun.

A few hours later, Mark's mom came home. They had dinner and Mark kept noticing that his sister would occasionally glance at him and her face would go red. He was happy to see that he was having an effect on her. After dinner he just lazed about in his room until bed.

The next day was Saturday which meant his mom would be home all day. He didn't have many opportunities to fuck with Ashley's mind because his mom was almost always around. But the few times he was alone with his sister he repeated the process of playing with her while time was stopped and then appearing naked in her presence. He wasn't sure how much he was truly messing with her mind but he would eventually find out.

On Sunday morning, Mark was taking a shower when he felt a presence and heard a faint 'click' noise. He looked around the bathroom but didn't see anything and figured he was just imagining things. He continued to expose himself to his sister throughout the day. Later that night around 11 pm, Mark was just sitting in his room when he wondered what his sister was up to. Stopping time he walked down the hall to her room. He noticed that the door was cracked a little and the lights were on. Walking into the room he was confronted with a sight that shocked him a little. Propped up on her pillows was his sister. She was sitting there completely naked aside from a pair of panties pulled to the side, with her legs spread wide and two fingers buried deep in her cunt. She had the most sensual look of ecstasy Mark had ever seen. Not one to pass up an opportunity, Mark ran back to his room to get his camera. He took multiple angle shots of her perky tits wet with sweat, her stuffed pussy, and the look of pure orgasm on his face. Once he was finished with her that night he'd save the pictures in multiple locations just like last time.

Mark decided he wanted to watch her in action and maybe get a nice video of it too. Setting up the camera so it was hidden behind some junk on her desk, he pointed it at her bed to get a nice view. Pressing play on the camera he hid himself in the closet and left the door cracked a little. Mark then started time and was treated to a real show. She pumped her fingers in and out of her moist slit and squeezed one of her tits with her other hand. Just the sight of his sister fingering herself was enough to get Mark at full mast. She was moaning too. Mark heard he groan out, "Oh Tim...". He had no idea who the fuck Tim was, probably some guy from her college. But Mark didn't want her thinking about Tim. He wanted her to think about him when she pleasured herself.

Stopping time, he stepped out of the closet. Walking up to the side of her bed he gently pried her eyes opened and stood at the foot of her bed naked. He slowly stroked himself as he started time again.

His sister immediately saw him and to his surprise groaned in annoyance, "Ugh...why can't I stop thinking about you...this is so fucked up." Fighting hard to keep a straight face, Mark just continued to slowly stroke his cock and maintain eye contact with Ashley. She had stopped stuffing her fuckhole for a few seconds but promptly resumed after giving a resigned, "Oh fuck it...". She picked up the pace she was at before and continued to play with herself. Soon she let out an, "Oh Mark...please fuck me...I don't know why I have these feelings but I just want your fucking cock in me." Mark had to stop time or else risk giving up the charade of being part of her imagination. He couldn't believe it. His sister had actually said that she wanted to fuck him. He had always planned on fucking her ever since he had realized what his powers could do but those plans had entailed doing it while time was stopped. He started to wonder if he could get her to fuck him while time was still running. Certainly something to try at least.

Looking back at her he decided to continue. Starting time again he began jerking off faster and faster. Ashley saw this and let out a sexy throaty moan, "Oh fuck yessss." She crawled on her hands and knees to the end of the bed so that her freckled face was about a foot from his pumping shaft. She continued to finger her cunt as she looked Mark in the eyes with lust. As he felt his climax building, he pumped even faster. Ashley noticed this and egged him on, "Yes! Fucking cum all over my slutty face! Paint your dirty sister with your cum!" That drove Mark over the edge and as he began to jizz he stopped time. When he finished he noticed that a sizable blob of his seed was suspended in mid-air not two inches from his sisters face. She had closed her eyes and looked prepared to take a facial. So Mark thought, "Why not give it to her?"

He went to the closet and peaked out. He started and stopped time in short succession. It was enough time to let the momentum still stored while time was stopped, to continue and plaster his sisters white face and make it even whiter. Exiting the closet he inspected his handiwork. One line of cum stretched from her right cheek, over her nose, and covered her left eye. Another shot had covered her lips. So much so that he couldn't see her mouth anymore. And a final load had gone high and wrapped horizontally across her upper forehead. Mark burst out laughing at the fact that he had given his sister a cum tiara. Grabbing the camera he had hidden he paused the video and took some more pictures of the masterpiece he had painted on his sisters adorable face. Finished with the pictures he started play the video again and re-hid it.

Mark decided to clean her face off. Grabbing some tissues he scooped the frozen cum off his sisters face. When the jizz crown was the last shot to clean up he decided he'd give his sister a nice present. Scooping up the cum with his finger he crawled up on the bed and pulled her panties out. Mark spread the helping of cum over the inside of the panties right where her pussy was covered and then placed the panties back over her private areas. He gently patted her pantie covered cunt to really mush his juice. Getting dressed he hid back in the closet and started time.

His sisters face held it's position for a few seconds before she cracked an eye open. Looking around confused all she saw was an empty room. She brought her hand to her face and tried to feel it. As if she expected something to be there. "Damn..." she said quietly sounding disappointed. She crawled back up to the head of her bed and went under the covers. She turned off the light next to her bed and soon she was fast asleep. Mark figured that would probably be the end of the fun for that night. He paused time and as he passed her bed he noticed the screen on her phone was lit up. Picking it up he saw that she had a text message. He didn't particularly care about the text but he did want to snoop a little. He searched around on her phone a little without finding much. The last thing he checked was her photos. As he opened up the app he noticed that the thumbnail last picture she had taken looked weird. Mark was shocked when he opened it up. It was a picture of him, buck naked in the shower. "So that's what that noise was this morning!" Mark thought to himself. His sister was spying on him while he was in the shower and had taken a picture of him! Mark smiled at the thought that his sister wanted to see him naked for real.
