One night I was studying before bed and my roommate came back a little early. She looked like she was in a bad mood and when I asked why, she said she was really hoping to have sex that night, but the guy backed out at the last minute so she was frustrated and horny. She said she was just going to go to bed, so she stripped down and got in bed. She laid there tossing and turning for a couple minutes before saying she couldn't sleep like that, threw off the covers and walked over to her closet, still naked. She pulled out her vibrator, plugged it in, flopped back in bed and started going to town. In no time she was squirming around, moaning and panting. After she came the first time, she rolled over onto her side with her back to me and squeezed her legs together and continued to let it buzz away. It wasn't long before she rolled onto her belly and started humping it, then cried out when she came again. She stayed there motionless for a few seconds before rolling back over and laid there spread eagle while catching her breath.
I asked her how it was and she said it was better than his cock any day. We laughed and she asked me if I wanted to try it, but I wasn't sure. She then said 'oh come on it's great, it'll make your toes curl'. I hadn't had an orgasm in about a week, so she talked me into it. The cord wasn't quite long enough, so I had to sit on the side of my bed, facing her. I pulled off my underwear and sat there, and when it touched my needy vagina, the buzzing moved all through my body. I couldn't even speak because the feelings were so strong, but when I was about to cum I leaned back and I started bucking so hard, my slippers even flew off. She told me to keep going and going, and by the time I was done it made me cum three times, and she was right, my toes DID curl because of it.
After I was done, there was no way I could study any more so I just rolled over and closed my eyes, still naked from the waist down.
I used it a couple more times, once with her and once without, but it wasn't long after that before I bought my own.
