Sleepwalking brother gropes his sister

Dear Diary Later that night my brother Tony sleepwalked into my room while I was reading. He fell over on the bed and began to grope me. I was pretty disgusted but I was afraid to wake him. To my horror Tony started fingering me and soon had a raging hardon. I gasped in amazement when he started fucking me and soon began to enjoy it. Next thing I knew we were both cumming hard.
