Today, I was lifting an old carpet, as we have a damp problem. Underneath there were hundreds of slugs and worms. My wife and I picked up about 40 slugs and put them in a pair of my wife's panties. I then put the panties on. The feeling was amazing. I got a huge erection and I could feel them sliding over my glans, and round my balls. Eventually I could feel one going up my bum. I knew I would come soon, so I let my wife tie me up, with my hands and feet speadeagled and attached to some furniture. She then took the panties down and about 15 of the slugs were crawling over my cock and balls. I came, spurting out loads of cum all over the poor things, but still couldn't move. My wife then took the other slugs out of the panties and placed them on my cock. She was careful to put some of them right on the opening of my cock, which was now covered in a mixture of sperm and glistening goo from the slugs. She opened up my arse and tried to put one in there too. I got hard again quite quickly as I thought of these slimy little things crawling over me. I imagined them biting me. One seemed to be trying to enter my uretha and this caused me to come again. That was 4 hurs ago. My cock is now very itchy, but I am about to give them another "feed".
