I found a great new way to masturbate! I work in a bank, and every evening after we close for the night, all the money gets packed away into the safes. Coins get put into little rolls and then wrapped in plastic. One time, I snuck a couple of rolls into my pockets as we packed up, because I don't earn that much. As I left the building, the security guard, frisked me as usual, to check whether I was stealing anything. I don't know how he didn't realize that I was taking money out of the bank. I also don't know what he did differently that night. Usually it's just a routine check, but this time it was like he lingered over my thighs and breasts, caressing them with his hands. Maybe it was the fear of getting caught, but it made me feel really horny, which is really strange, because I'm a lesbian.

By the time I got back to my car, all I could think of was the hard, long roll of coins in my pocket. I sat in the driver's seat, pulled up my skirt and pulled down my panties. I switched the radio on. I put the seat back and listened as I started to feel hotter and hotter. I started to rub on my clitoris, just to get things warmed up. It felt really good!

After a while I remembered the roll of coins, so I pulled it out. It felt cool and hard, and incredibly sexy. As I was still rubbing my clit, I slid the coins, which were still in the plastic wrapper, inside my vagina. It was amazing! The coins were really cool, almost cold, and hard, and slightly bumpy, because of the plastic and shape of the coins.

I started to rub my clit harder and faster, as moved the coins in and out of my pussy. It felt really incredible, and I couldn't believe I never thought of doing this before! In just a couple more minutes, I started to feel warmth spreading from my vagina, up through my belly, and then all over my body. My nipples were rock hard, and throbbing, and contractions of pleasure were starting deep inside my vagina. My clit was buzzing with excitement.

Soon, I started to whimper and shake. After much less time than it usually takes me to orgasm, I had this incredibly powerful climax that sent waves through my entire body. I lay back in the seat as I was literally twitching with pleasure.

When I eventually recovered, I put my clothes back on and drove home. I couldn't stop thinking about how nice it felt when I slipped that cool roll of coins into my vagina. I had the idea of putting the roll in the freezer when I got back home. So, I ran up the stairs to my apartment. I was so eager to try out my new idea. I decided to leave them in the freezer for five minutes, and then see what that felt like. That was a very long five minutes that I waited!

I sat and played with myself, because I just felt so aroused! Eventually the time was up, and I ran to the freezer, pulled out the coins, and carefully slid them into my pussy. -- Wow! -- That's the only word to describe it. It was a shock how cold the metal was after just five minutes in the freezer. It sent little shivers of delight from my vagina. I didn't get much sleep that night. The next morning I slipped the roll of coins into my vagina, and went off to work. I left them in there the whole day. It was really sexy to serve customers at the bank with a roll of money deep inside me. I sat at my desk and carefully played with myself the whole day, and it was the most incredible feeling in the world!
