I had my nipples pierced last year, and it added an entirely new level to both sex, and masturbation. My nipples are so sensitive now, and constantly erect. The slightest caress, and I become aroused. While I hadn't been able to orgasm directly from my nipples without touching my clit, I could cum in less than a minute, if I play with my nipples for about five minutes, then rub my clit.
Sunday I was bored, and spotted a peacock feather my Mom has in a dried flower arrangement. I grabbed it, ran to my room and got naked. I gently flicked the feather against my nipples, and gasped. It was like a bolt of electricity beginning at the tip of my nipple surging to my clit. I fought the urge to touch myself, and continued to tease my nipples until the sensation became too powerful, and I had to rest.
Then I would start over again. I looked down at my crotch, and it glistened with my wetness, and there was a wet spot on my sheets. I put a towel down, and started the nipple ecstasy/torture routine with the feather again, cupping my breast with my left hand to keep it from the temptation of my soaked pussy. My nipples were as hard and erect as they had ever been, and I was determined to not touch myself. My hips began to thrust, searching for any object to quell my lust. My gasps became moans, my body was covered in small beads of sweat, and my chest flushed red.
I stopped, exhausted, needing to catch my breath. I looked at my clock, and I had been at it for 20 minutes. I carefully parted my labia, and gazed at my clit. The pink nub was larger than I had ever seen it before, and seemed to throb with each heartbeat. I rubbed my sweaty breasts taking a break from the feather, pulling, twisting, and massaging my hardened nipples, and flicking my nipple rings. I returned to the feather, and decided I couldn't take it anymore, and needed to cum. As I slid my hand down my belly, and touched my navel, I felt it. Slowly a tingle from deep inside me began, slowly rising in intensity, until my orgasm started. I quickly began tugging my nipples hard, and the orgasm intensified into the greatest, longest one of my life. My body twitched for almost 10 seconds of pure pleasure, then slowly receded into exhausted relaxation.
I moved my right hand down and gently touched my soaked labia, and worked my fingernail up to my clit. I gently rubbed, and immediately felt another orgasm building, and I began to finger myself, and moved my other hand to my clit, furiously rubbing it. I came again, almost as strong as the first one, and only a minute later, the first multiple orgasm of my life.
