Was at my friend house a couple of months and we were drunk and stoned. We were all swimming and his wife went in to go to the bathroom. I went in a couple of minutes later and caught her playing with herself on the bed. When she saw me she just smiled and turn over onto her hands and knees ,reached back and spread her ass open and told me to pick a hole and to hurry up before someone else came in. I was in shock at first but when she told me hurry up before i change my mind, i pulled out my alread hard cock and shoved it in her ass. It did not take long before i cam in her ass.As my cock slide out of her ass it slide down her crack so i stuck my half hard cock in her pussy too. I fucked her a little and we heard someone coming in the house so i pulled out and went into the bathroom. We have never spoken of it since.
