I took the soap and generated good lather. I applied on sister;s asshole and slowly inside the asshole. My cock was covered with soap water. Now the going was bit smooth. With a little bit of pressure half an inch of cock went inside. I rested again I pushed little further it went in. My sister was in little bit of pain and was sweating..
