One day when I was off from school, I decided to just lay around the house in my pajamas all day. The first thing I did when I woke up was turned on the heat, had breakfast and went to lay on the couch and watch TV. I laid there for a while and fell asleep, but when I woke up, my pants had ridden up on me and the seam was rubbing between the lips of my vagina. I don't wear any underwear when I sleep, so it had slid right in. With every move I made, it would slide back and forth and against my clit. I wiggled around for a few minutes, getting my pants all wet and sticky, until I yelled out and came hard. I looked down and saw that I had a big wet spot between my legs, which made me feel even naughtier.
The rest of the day, I masturbated whenever I wanted all over the house, comfy and cozy in my jammies and slippers. One of the times, I even did it in my parents' bed.
When it was about time for them to get home, I didn't want them to see me walking around with a big, crusty spot of my cum between my legs, so I changed to a different pair of pajamas for the evening. After dinner, they went upstairs to their room, and I stayed downstairs and watched some more TV. I wanted to masturbate again, so I made sure the coast was clear, pushed my pants down to my knees and quickly rubbed myself. the thought of them walking in on my made me even hornier, making my nipples rock hard and my toes cross and curl inside my fuzzy slippers. After I came this time, I made sure to clean myself so they wouldn't know what I just did.
After playing with myself all day long, I went to bed and slept like a baby.
