Just to refresh from last time. I have bought two thongs and found that I would cum almost as fast I could put them on. It had been a week since I had bought my first two thongs and wow the fun I had with them. I'd go to class see sexy thongs on girls, run home putting one of mine on and instantly cum. Then the feelings of dirtiness and humiliation would set in quickly and I'd take them back off and hide them away again.
I found that it only took one or two sessions for them to be cum stained and needed cleaning. Sometimes they would still be wet with cum from a previous session and would be cold and cling to my throbbing cock as I pumped yet more cum into them. This is also when I discovered humping my pillow.
I came home from class with a good picture in my mind, I put my white thong on went to grab my cock for its one stroke and then thought to myself I should practice having actual sex so I took my softest pillow and put it on the edge of the bed. Lowering myself onto it I could feel myself go tense, I slowing slide my cock backward against the pillow and then slide my cock forward in the slick satin. I could feel the cum trying to push through the material that blocked its escape, I pushed hard as the orgasm pulsed through my body. Standing up I had left a considerable mess in my panties and on my pillow. I thought to myself you're a dirty boy and should have to stay in you dirty cum panties. I had class again in an hour so I left them on. This was a big change for me. I put my pants back on. I couldn't believe what I was planning on doing wearing my dirty cum filled thong out of not just my bed room but out of the house. What if someone sees it, what if I'm like one of those sexy college girls showing my thong off? Oh my god, what's wrong with me I'm getting hard just thinking about getting caught in my thong.
