My mom cleaned up gallons of dried cum from under the side of my bed

OK so this actually happened 8 years ago. I was 16 and was just getting into the habit of watching porn on my phone in bed on the iphone 3GS at the time. Now keep in mind that my parents are very religious and conservative, and I grew up in what you'd say a privileged household as well. Almost every night right before going to bed, I'd watch porn for about half an hour whilst slowly stroking my dick. Just as I'm about to cum, I'd tilt my body sideways, dick aimed at the wall on my right, and shoot straight down there. I was in the mentality where "if it's under the rug no one will find out" similar to when you drop chips on the floor. Anyways, I kept doing this for about a year, and I never really bothered to look under the bed. One day, my room was messy and my mom was pissy. She walks in, yells at me for having a very untidy room then she says that's it, we're deep cleaning the room right now. She makes me go fetch cleaning stuff to help out. I remember being very pissed off because she interrupted what would be my afternoon fap session. So carpets removed, furniture moved around, and deep cleaning commences. When the bed was moved to the side, I almost shat my pants when I saw the horrific view of what was under. Sticky, yellowish, dried cum which was tainted down the wall, and into a massive puddle that had about a 10mm thickness, and you can actually see ants, and small roaches whom have been caught up and died right in that puddle. Now my mom casually asks "what's this?" In panic, I told her that I was having Ice cream in bed one day and that I spilled it to the side, and forgot to tell her about it. She got x100 angrier at this point, telling me how careless and dirty I am. Nevertheless, she seemed to have bought it. Several minutes later, she started scrubbing the puddle of cum while I was looking in shame. I felt like the biggest sack of shit on earth. Feelings of disgust, shame, and guilt overwhelmed me. I vowed to not masturbate to the side wall anymore. Anyhow, the nightmare didn't end there. Aftera few minutes of scrubbing, the now wet puddle of cum starts to emit odour. Shortly after, the entire room smelled of cum. It was the most disgusting smell you could imagine. I was horrified and didn't know what my mom was thinking at the time. I was just playing dumb and was pretending to move around shit in the room to make it seem I was helping her, when secretly I was shitting my pants. At the end of it, she just said to me "Remember, god is always watching. He's very unhappy with you." and left. Religious me back then cried in the same night, and I was begging for god's forgiveness for weeks in end. Not too long after however, I realised that I learnt my lesson, and that's when I started using tissues in bed.
