This one time, I felt crampy and knew my period was comming on, but I figured I could make love with my husband before the bleeding began. Now, my hubby and I are into mutual masturbation; he strokes his hard on while I'm laying face down in bed, and hump my pillow. Well that day, I hammered my pussy into my pillow, working up to a yummy orgasm, totally putting those yucky cramps out of my mind. When I was done, I rolled over onto my back, when my husband, obviously reluctant to hurt my feelings, hesitantly drew my attention to my pillow. I looked in dismay at the bloody stains I had left on the fabric of my pillow, after I had rubbed my pussy against it. Geez, I felt so stupid! Why didn't I just lay a towel over the pillow, before I did the nasty with it? I felt crampy, after all, so I had no one to blame but me for ruining my favorite humping pillow!
