Whatever remains, no matter how improbable, must be the truth?

As they got back to the kitchen from putting away the bags, Matt heard a key slide home in the rear door, simultaneously, Peter stepped back from Clair, who stood up, and his and Brandon's pants suddenly had a crotch again. The door opened and Hannah came in, leading a train of little elves bearing wrapped presents. "We're back everyone," Hannah said. "Hi Brandon," she added, and the kids each echoed her. "Okay, to the tree!" she said to cheering, and the group filed out of the room. They rounded the corned between the kitchen and the rest of the house, stopping to say hi to everyone in the dining room. Peter, who had starting doing dishes when he stepped away from the oven, put them down and stepped behind Clair again. She raised a leg and let him slide his suddenly once again bare cock into her as Matt noticed his and Brandon's were again loose. They thrust a couple time, then stopped, Peter pulling out and going back to the dishes as crotches were again covered. Matt had whiplash by now. A second later Rose came into the room and got some water, then left. She turned the corner and Clair grunted as her father thrust back into her, grabbing Brandon's exposed cock and began giving him a handjob him as he obliviously tried to sweet talk his way around the car issue while using the food processor.

Matt had no idea what was going on. He headed toward the rest of the house. As he turned the corner, his pants were back. He stopped. He stepped back around the corner and he was swinging free in the air again. Forward clothed, back unclothed. Everyone in the dining room gave him a weird look, as he came into and out of their view.

"You ok their, bro?" Mary asked quizzically.

"Oh yeah, fine, I just... uhh.. I keep thinking I forgot something," Matt put in lamely. He noticed everyone in the room was normally dressed. He backed up just a little so he could see the kitchen, and Clair was still fisting Brandon while her dad fucked her despite them appearing to be having an argument. What was different? Suddenly he saw Clair let go and Brandon's cock get sucked into his pants as they reformed, her father stepping away from her as she stood up to use the stove normally. Damon walked past Matt to get a drink, and it clicked.

Everything went back to normal the instant one of the three kids came into view. It stopped out front earlier too, when there was a chance their could be kids around or in cars going past (Matt hadn't been paying attention, but in all likelihood there had been some people going by at some point, as setting up had taken nearly half an hour). There hadn't ever been anyone underage around when things got sexy the last few days either. Whatever this was seemed to keep kids out of it, going back to normal if there was even a chance they might see it! Matt actually felt a little better with even that small bit of understanding, even if nothing else made sense. And also relieved he didn't have to pay attention to that himself.

With nothing to do, Matt excused himself and went upstairs, Sarah reminding him dinner would be in a few once the food finished. As he went up the stairs he paid close attention. As soon as he was on the second floor, with no chance anyone could even glimpse him through the railing gaps, his cock was suddenly in the air again. This seemed to confirm his theory. Just to check, in his room he sat down at his laptop. Instead of the mouse, there was a fleshlight. Matt tried a couple times to turn on the computer, but the power button wasn't even there anymore. He finally picked up the fleshlight and lowered it onto his cock. When the tip touched the screen lit up, but nothing else. Matt lowered the fleshlight slowly onto himself, the computer (which had an SSD) booting glacially. When he was halfway down, Matt just slammed in the rest of the way and the PC instantly booted up. He started jerking off with the fleshlight, noting worriedly he couldn't stop, and also that he could move the cursor easily by altering the angle of his trusts, instinctively using his dick like an oversized thumbstick, having no trouble navigating doing so. Just to check, he moused over to sleep the computer. As the PC went down, Matt came hard into the flashlight. After catching his breath and noting again his erection hadn't flagged at all, he pulled it up and slammed it back down and the computer came back up as if he had hit the switch.

One last test, Matt decided. "Hey Damon, could you come up here for a second?" Matt yelled downstairs. There was a pause (during which, despite his not doing anything, Matt couldn't help but keep thrusting the fleshlight on himself absentmindeley) and then he heard steps on the stairs. At that instant the fleshlight came off of him, pulling his hand along with it as his pants rewove and he suddenly had his hand on normal mouse sitting on the table. A short while later Damon came in, looking inquisitively at Matt. "So what's in the boxes," Matt said, using his prepared excuse.

"Nu uh, you know you have to wait for morning," Damon replied, wagging his finger.

"Come on, I'll tell you what's in yours..." Matt wheedled.

Damon stuck his hands over his ears "I can't hear you!" He cried. Matt raised his hands in defeat.

"Fine, go on then," Matt said, sticking out his tongue. Damon laughed and ran downstairs. Matt heard him pounding down the sitars, and the instant the sound stopped the mouse flew off the table, Matt unable to let go, wrapping around him to become a fleshlight again, as Matt's hand uncontrollably returned to moving it up and down on himself. That out of control bit was disconcerting, but at least Matt felt he now had some idea what was going on. He also idly checked the net in a few places and found no pornified TV shows, so whatever that had been yesterday seemed to be done. Everything online looked normal. That indicated something different was happening each day, maybe? Too small a sample size, his engineer brain mused. Also not sure why yesterday included both TV and the game; that rules out 'all TV is porn' as what was happening yesterday.

As far as the rest of Christmas Eve went, nothing else unusual happened, as the kids were basically around the whole time and, as per family tradition, they all hung around playing board games and such well into the night. As they all went up to get ready for bed, Matt asked if anyone could give him a hand in his room, and Mary agreed.

"So what did you need, bro," she asked when they got there.

"I just have to handle some emails," Matt replied as he sat at his desk. Rather then her asking why he needed her for that, the door swung itself closed and both their pants' crotches vanished. Mary shrugged, pulling out her normal phone, and went over to the desk. The desk got taller as a cushion appeared beneath it. Mary knelt down and began to blow him. The PC woke from sleep, and as Mary played a game while sucking him (having no issue despite her head bobbing up and down or due to the awkward position); Matt actually did work on his emails. While thoroughly enjoying the sensation of her mouth gliding up and down on his cock, he had no trouble reading or writing replies. As he hit send on the last email, he suddenly and without warning went from just enjoying her actions to cumming hard into her throat. As if his statement that he just needed to check emails was being enforced, the PC shut down as he filled her stomach. She gave him a quick suck to clean him as the PC turned off, then got up and left, the desk and clothes returning to normal as she turned the doorknob the door. Lucy was walking past from the bathroom when she opened it. Matt got ready for bed himself.

After a few minutes, his dick was suddenly exposed again even though his door was open. He stepped into the hallway and saw a yawning Aunt Hanna headed to the bathroom. "The kids are asleep and I need to brush my teeth," she commented as she walked past, holding up her electric toothbrush. She kept going for a second, then looked back at him quizzically. "Are you busy?" she asked. Matt realized what she meant and followed her into the bathroom. She spread toothpaste on the brush and reached back with one hand to grab him as she leaned over slightly. The back of her robe had an extra slit, which caused it to fall away and leave her naked ass pointing at him, and she guided his dick to her gates. The toothbrush whirred to life as he slid in, and he set up a gentle rhythm, so he wouldn't push her against the sink too hard.

"Glad to see you helping out," Sarah commented, stepping past her rutting son in a robe to brush her own teeth with her manual toothbrush. Hanna put down the brush and gulped a bit of water. As she spat, Matt hilted into her and came hard, cum gushing out around his dick and running down Hanna's leg as she lightly moaned.

"Thanks, Matt," Hanna commented, brushing past him and headed back to her room. Matt picked up his own toothbrush and cleaned up, noticing that his pants re-sealed for second before he heard a door close; that must have been Hanna joining the kinds in the guest room. As soon as the door clicked hut, his dick was exposed again. Matt and his mother finished brushing and he went to bed quickly, before she could draft him to help with a hair dryer or something. Matt drifted off to sleep a short while later.
