“Goddamnit,” Ryan thought to himself, “I just hope somebody finds me quick this time.” You see, Ryan often heard stories of how his father’s family descended from a line of sorcerers but it has been nearly a millennium since anyone has been gifted these powers. Unfortunately for Ryan he had begun showing signs of his bloodline’s powers when he began puberty, but by that point his father was already out of the picture and he was left to figure things out. Luckily his sister and mom have been supportive and understanding of him as he hasn’t mastered control of his powers.

Now what were his powers? Well Ryan came from a line of sorcerers that used their powers for espionage and assassination as they were able to willingly transform themselves into any nearby object which made them tricky to detect and find. This also wasn’t the first time Ryan had accidentally transformed. On his 18th birthday he accidentally transformed into a chair which his mother sat on, unaware that it was her son. Over time Ryan found out that if he transformed into something that he would transform back after 24 hours but only if he had space to reform. If he didn’t have enough space he’d simply be stuck as an object for 24 more hours, which has left him trapped for a couple of days before.

This time though Ryan had panicked and used his abilities as he was rummaging through his sister’s room looking for some spare cash he could borrow when he heard her come home from work. Not wanting to get caught he had used his abilities with no object in mind and was transformed into something in a soft yet claustrophobic space.

“… yeah I can cover your shift tomorrow! Uh-huh. Yeah. Okay bye.” Ryan heard his sister Anna hang up the phone. He already knew that she couldn’t hear him if he called out and that it’d take her awhile to notice he was gone so he sat content with waiting it out. That was until he felt a sudden jerk as whatever container he was in was jerked forwards. “God, work fucking sucked! I don’t know why I agreed to cover her shift.” Ryan heard his sister complaining about her job from what he assumed was above him.

Ryan’s suspicions were confirmed when he felt her rummaging through where he was before he was shortly blinded by light. As his vision cleared he saw his sister holding up some panties and staring down at him. “No! Don’t tell me I’m her underwear! This is way worse than when I was her jeans.” She put the panties that were in her hand to the side before lifting Ryan out from his confinement.

Ryan could see the stress in his sister’s face as he was lifted up and out of what he could finally tell was a drawer. “Fuck I need to destress,” Anna muttered to herself as she, unceremoniously, tossed Ryan on top of her bed and began stripping out of her work uniform.

“Fuck… I forgot how big her ass is. And I hope she takes a shower before putting me on.” Anna was bending over, pulling her panties off her legs, which gave Ryan a nice view of his future torturer.

As she peeled off the last of her clothes she turned around towards the bed, walked over to it, and plopped her ass down right next to Ryan. “God I’ve been looking forward to this all day.” Anna picked up Ryan and maneuvered him to her back side, pushing him up against her ass.

“Wait Anna! What are you doing?! What am I?!” Ryan silently pleaded with his now giant sister as she began pushing him against her asshole, the stench of her unwashed and sweaty ass flooding his senses. “Please stop! Please just hear me!” She suddenly shoved Ryan’s inanimate body into her asshole, causing the walls of her anus to clench around the intruder.

“Oh god! This feels good!” Ryan heard his sister’s muffled moans as he was thrusted in and out of her ass, being tormented by the taste and smell of her unwashed ass. Each thrust causing her smelly and tight anus to clench and grip his silicone body, staining his body in its stench and sweat. This continued on for hours as Ryan was assaulted by the stench and shaken in and out, in and out, until her ass death gripped his body and the thrusting finally stopped. “Ah- ah… I really needed that.” Anna moaned as she pulled Ryan out of her ass with a loud popping noise. “I’m surprised Ryan isn’t home. He usually never goes out.” She paused as she got up from her bed, unaware that the dildo that she used to ravage her ass was her brother, “It at least gave me an opportunity to destress.” She opened up her panty drawer and dropped her dildo back into its dark prison.

“What the fuck! At least wash me!” Ryan fruitlessly called out as he heard his sister open her door and leave. “Man… I’m gonna be stuck like this for ages! Fuck, I was Anna’s jeans for 3 days and only transformed back because she just through me on her bed rather than putting me away!” Ryan began panicking as the reality of his situation settled in. “She’s not gonna think I’m her fucking dildo! She’s not gonna tell mom about it…” If Ryan had a mouth and lungs he’d be hyperventilating right now but all that anyone would ever see was an inconspicuous silicone dildo stuck at the bottom of a drawer, as it should be.
