The Backstory: It's not usual for me to have a boy sauntering around, but when one offers to fill me up with his cum and watch it spill out of my menstruating cunt into a pristine pair of designer panties...well, it makes me think I'm ready to change my ways! I think I got a blood bath from Cupid! Late last night I slipped these panties on at my suitor's request. It was going to be our first time consummating our new love, and he proposed we capitalize from the occasion. What a good boy! My dog watched from the sidelines as I grabbed a handful of my new man's hair and he slipped my little DKNY thong across my swollen lips and slid his raw cock into my bloody period pussy. He fucked me in a traditional manner (if you consider getting fucked in your panties on your period to be traditional) then flipped me over and went deep, whispering that he was going to give me his cum and put his baby in me. The whole breeding fantasy is new to me, giving it heightened erotic appeal. He came deep inside me, and when I felt his hot cum hit the wall of my cunt I couldn't help but cum, too. I turned over and held his head while he sucked on my nipple like a little baby and we watched my panties fill with our cum-blood cocktail, then watched the cocktail spill onto my sheets. We slept in the mess and we were both pleased this morning when we woke up and examined the panties. They are heavy with cum in scent and texture...I smell his more than mine, but feel mine more than his. My period seems only to have played a part in discoloration, but you'll have to judge that for yourself. Whoever gets these size small DKNY panties will certainly have a lot of tastes, smells, textures, and fantasies to enjoy.
