19M, day 2 of my dexamphetamine binge. So I'm a bit of a deviant you could say, I'm completely straight and heterosexual for the record and I really did not expect this from myself. I know where my sister keeps her anal plug so in my whacked out state I decided it was time to try something new. It was about 11PM and my whole family is at an official dinner place with relatives, which I did not attend as I was pretending to be extremely exhausted after work. I sneak into my sister's room and fish out her anal toy from the space between the sheets. I am really aching for another orgasm at this point so I quickly spray it with rubbing alcohol and run to my room. There I huddle in a corner, because I'm expecting my whole family to burst through the porch door any second, and stretch out a condom over her toy. I then proceed to lay on the bed and shove this black serpent up my ass. I get condom lube all over the sheets but decide to clean it later (when exactly this "later" was going to be I had yet to decide). I'm laying sideways on my bed thrusting this thing out and into my sore asshole while flailing my limp cock around, completely wide eyed, definitely looked like I was some sort of feral beast from the outside. Eventually I cum but decide one time wasn't going to be enough so I started up the vicious cycle one more time. Problem is at this point my cum cisterns are just about drained, I have to wack off upwards of 30 minutes to get any sort of pleasure and even then it lasts like 5 seconds. At around 0:30 AM I hear the front door open, and guys the panic that I felt was nothing like you can imagine. My vision literally went hazy because I was this close to being found in a cum and lube soaked bed and probably being fucking executed on the spot. My door creaks open and I close my eyes and pray that my jaw doesn't decide to play hopscotch. My mom opens the door slightly, sees I'm "asleep" and shuts it. I kept masturbating for about 5 or 6 more hours. I write this as I lay in a crusty, disgusting, cum filled bed with excrement laced lube around my backside. I don't know how I'm going to clean this in time for my family waking up but I sure do hope I think of something fast.
