Your stepdad Brian stands in front of the mirror snapping of photo of his new boxer briefs…which was really you, his stepson. He has been really strict ever since your mom left. He had a curfew and didn’t let you out after school, so you had been skipping some of your classes to spend time with your girlfriend, Becky.
After getting home from a particularly fun make out session with Becky, Brian, since you refused to call him Dad, is waiting from you. He confronts you with a notice from the school “Son where were you today?” He asks “Uh I was at school…” you say a bit sheepishly knowing you had been caught. “Really well I just got a call from the school and this letter today, and they just told me you have been missing the last two periods for the last week and your grades have been falling.” “Uh….well um they must have made a mistake…..” “Lying on top of skipping school will get you nowhere boy,I have half a mind to……” “Aw come on Brian… I was just hanging out with Becky, I’m 18 and I’ll be in college next year” you snap knowing he hates it when you address him as Brian. Brian’s eyes flashed and his nostrils flared “That is it, you will be happy to know you won’t have to go to school tomorrow or for the rest of the year. You’ll be making it up in summer school. Until then I am going to put you someplace where I can keep an eye on you” he says menacing “Aww come on you can’t homeschool me, what about Becky and graduation….” you whine but before you can protest anymore, but he pulls out his phone and opens an app. You see a flash from the camera and suddenly start to feel sick. Your body gets warmer and starts to feel like it is melting. Your body starts to flow down, sliding down onto itself, pooling into a blob, then slowly you melt and shift, your body shrinking and changing, your body transitions from flesh darkening into a blue fibrous material until you fully reform into a pair of blue boxer briefs.
Your stepdad smiles down as you and strips naked and starts to pull you upward. His massive legs step into you and stretch your now fabric body. He adjusts himself through what would be your face. “Nice and comfy son?” He jokes patting you. You gag as he rubs you against his hardening cock and can taste his precum. You can’t believe this is happening to you. One second you are a living breathing person the next you are a pair of boxers stuck on your step dad, tasting and soaking up his sweat and worse.
You life soon becomes pure torture, your step dad wears you almost every day, only taking you off maybe once a month to wash. You are soaked daily in his cum, sweat and piss, tasting and drinking each drop that is absorbed into your cottony body. Over time you start to lose yourself, the more he wears you the more you started to enjoy the taste of his cock. You crave his sweat and cum now. When the school year ends, and he finally turns you back.. You are disoriented “what….I can move…..” you say dazed moving limbs and muscles you hadn’t moved in awhile. “Well I hope you have learned your lesson, son” Brian says “yes Sir…” you say a bit dazed. You spend the next day adjusting to being human again and being able to move, but you can’t seem to shake off this feeling of being empty. By the second day you can barely stand it, you need to be filled again. You go to your step father’s room “Sir, I miss being your boxer briefs……it feels weird being a man again” you say to him “You don’t miss Becky at all” “No Sir, I just need your cock….please can you make me your underwear again.” “Well son, you don’t have to have my cock in you” he says pulling out his large uncut cock, unable to help yourself you run crawl to his cock sucking on it furiously. You savor his cock, sucking and slurping on it, the taste so familiar and filling. His cock hardens with your ministrations getting even larger, he pumps your mouth pushing you deep onto it. He thrusts faster and faster till your stepfather explodes hot semen into your mouth. “Better son?” he says “Yes Sir..” you say satisfied “Actually I don’t think being human is going to be bad” You say looking up and see him with a large grin pointing his phone at you and with a flash you feel the familiar feeling of falling as you reform underwear.
