One afternoon a few years ago, my mother and dad were at work and my sister and her girlfriend were out somewhere. I figured the two girls would be out for awhile. So I decided to ride my exercise bike totally naked. I was riding the bike for 25 minutes or so when all of a sudden I heard my sister and her girlfriend screaming with laughter. I didn't hear them come up the steps because the bike is a little noisy when anyone rides it. I jumped off the bike and tried to cover myself up with my arms but it didn't do any good. My sister told me to put on my underpants to lessen the embarrassment. My sister asked me how long I have been riding the bike. I told her 25 minutes
and she said good. I don't know what she meant by that. Then I knew what she meant when she made me sniff the bicycle seat for a few minutes and made me lick the bicycle seat for 10 minutes. They were getting a charge out of it. Afer I was done kissing and licking the bicycle seat, they made me give the bicycle seat 10 more kisses and 10 hard licks. I think I will use the exercise bike when I am totally dressed.
