I was so excited to get Katie in rainwear, I grabbed a funnel and put it down the front of Katie's rain suit and start pouring gunge in... she did the same to me and it felt so good running down my chest and onto my belly. Her hood needed filling next of course and then we poured more and more down our suits and over ourselves before taking them off and emptying the wellies on each other. We were naked and all slippery from the gunge, it felt so sexy! Katie thought so too and we pulled out our dildos and fucked ourselves in all of that mess.
