Normally I wait until I take a shower or go to bed to masturbate, but one day I needed to when I got home from school. I hadn't cum in a few days and it was all I could think about.
As soon as I got home, I dropped everything and went to my room, locking the door and stripping naked. I teased my pussy for a few minutes before I grabbed my toy, slowly sliding it in and out working my way to my orgasm. I rolled onto my belly and was humping it when my mom knocked on my door. She said I had a bunch of clothes in the dryer and I needed to fold them. I let go of my vibe and asked her if it could wait but she said it needed to be done now. I was mad, but my pussy was fuming. I hid the vibe under my pillow and threw on a t-shirt and sweatpants and stormed downstairs. I was so aggravated I didn't even bother with a bra or panties.
I grabbed my pile of clothes and started folding them on the couch, huffing the whole time. My mom could tell I was mad and asked me what was wrong, and I said nothing. She asked again and I told her I only needed a few more minutes but I HAD to do this now. She stood there for a few seconds and asked me 'wait...were you masturbating?' I took a deep breath and told her 'yes, and I was right in the middle of it too.' 'Oh I'm sorry honey. Why didn't you just say so?' 'Well, it's a little embarrassing to tell your mother that you're masturbating.' She told me there's nothing embarrassing about masturbating, and that you're just doing something that feels good. She then said she would finish folding my laundry and to go back up to my room. I hugged her and ran back up. I didn't even bother closing my door, I just pushed my pants down to my feet and attacked my aching pussy with my vibe. In seconds my back was arched and my orgasm ripped through me, this time stronger than normal.
I pulled up my pants and laid there for a few minutes with my eyes closed. My mom then walked in with my laundry basket and asked me if I felt better. I said that I felt great, and she said she was glad, rubbed the bottom of my bare foot and walked out.
Since then I was interrupted a couple more times, and all I said was 'hang on mom, I'm masturbating', and she just said 'OK, come down when you're finished'. It's great being able to be so open about it.
