Not Long At All

You could vaguely hear the water running down the hall, though it was mostly drown out by your biggest problem....the constant hum of the device currently massaging your dick. You bit down on your gag hard, droll running down your chin. Your eyes were shut as if that would help. You tried to think of something, anything to turn you off. Your mom and dad coming in, a burglar putting a knife to you. It just wasn't working as your dick just kept getting harder and harder by the second. And that harder it got, the more it pressed into the vibrator, the more it felt the soft material you were currently stretching out.

It didn't matter that it as your sister's panties, with the pent of stress you'd built up waiting for this moment you were just quivering for release. You squeezed the arms of the chair as you cam...shooting gooey wads straight into the tented panties wrapped around your dick. Your body trembled as you had easily one of your best orgasms...in easily the absolute worst way.

"Alright bro, how are ya doin?" Amy's voice called out. You hadn't even come down from the euphoric high and felt the typical post-orgasm shame. "Fucking really? It wasn't even five minutes..."

At this point, the shame began to settle in and you slumped over, feeling drained. Amy didn't say another word, instead she just went to work. You were too out of it to fight back as Amy untaped the vibrator and untied your legs and pulled off the wet panties. Too dazed to fight back as Amy pulled something different up your legs. This garment flattened your cock, but also made you nearly jump as the thin string ran between your cheeks.

"Upping the ante now...THAT is one of mom's thongs," Amy eagerly told you as she reapplied the bonds on your legs, "Its a sexy black number....just so you can imagine creaming in that too."

Amy left you to yell gagged curses at her while she fiddled with her phone. Eventually there was a click of her camera app. It didn't take a genius to guess what she'd taken a picture of.

"MOM! Look what I found in John's hamper! The loser fucking jacked off with my underwear!" Amy read off a text message, before reassuring you. "Relax...I haven't sent it....but just so you know, its just one click away....got it."

Amy waited for you to nod in confirmation, a bit weakly...more defeated than unsure. Amy took it for what it was and you could soon hear the click of her phone locking and the clatter of it being set on the table. Still, that didn't mean she was going to take your weak nod without a little payback.

You felt your gag loosen and for a moment mistook it for kindness on her part. Amy made sure to correct that idea as you opened your mouth to speak. A clump of fabric was **** into your mouth, sticky wetness brushing your lips before settling on your tongue with a taste you didn't even want to begin to describe. Before you could spit out the panties, Amy sealed them in, tightening the gag back up.

"How's it taste? Pretty salty right?" Amy demanded, grabbing you by the chin and forcing you to face her. You were close enough to practically feel her grin. "Think I know what to do with that **** now...."
