By your degenerate sister

"Hey, brother, nice pills you took, I didn't think it was possible to swallow and digest things like that"

You froze in place as you realized that your life was over: your big sister witnessed the whole show you did down there, and if she told mom and dad, oh God, panic started swelling up within you.

"Hey, calm down, I'll tell no one, in fact I would love to see you do it again. Come to my room, and don't worry about the missing things on the fridge, I'll lie to mom about it"

You were nervous but, lacking choice, you still did what she asked. Her room was were mature and womanly although it clearly demonstrated how much of a pervert she was, disorganized and with clothes all over the floor, she sat down on her gaming chair and signalled me to sit on her bed.

"Okay, that whole thing you did down there made me super horny, and I thought it was impossible that someone like you would make feel like that"

"Yeah-" you tried to reply, red in the face "I wasn't very hot, more like "cute and feminine" as my friends say..."

"Whatever" she cut your cry short "like I said, I'm soaking wet, and I want you to do that again and let me record it. I really want that as fapping material"

You knew she was a degenerate, but holy hell, that surpassed your expectations. While the idea of doing it on camera excited you a lot, she was your sister and it felt strange. As you fidged around you looked at her and noticed a strange look on her face. Suddenly she jumped at you and pulled your pants as if she wanted to rip them off, she closed her face on your newly enhanced shaft and sniffed it with a face of pure bliss.

"Okay, I'm not sucking you off because you're my brother but I'll give you a handjob if you eat the things I give you"

"A... alright, I'll do it"

"Yeessssss!"

She got up an walked to her wardrobe where she grabbed a ton of old clothes and random stuff that she curled in a ball, then she fetched a tripod and a digital camera from one of the drawers on her desk, mounting it she started recording without a signal.

"Stand up close to the camera, and let me do the job"

You did as told, posing for the camera with your foot-long monster shaft clinging to your chest. Your sister smiled, pulled it towards her and pushed the ball of clothes on your tip. Your cock happily obliged as your tip quickly opened, warping the ball in a wet grip as you instinctively began to suck it down your urethra, pulling it towards your hungry ballsack.

The soft sensation of the fabric inside your urethra as you pulled it inside felt really good. Your greedy cock quickly slurped it in a couple seconds.
