One of my coworkers mentioned that she was having problems with her sprinkler system at home. I volunteered to come over after work and see of I could fix them. I went over there after work and ended up cleaning out the little screen on a few of the heads. I popped inside and let her know everything was working. She threw her arms around me thanking me. The hug lasted a little long and we were looking each other in the eye. Next thing I knew we were all over each other. She moved us into her living room and I bent her over the arm of her couch and plowed her hard. She was really vocal and was telling me to fuck her hard. I grabbed her hips and railed her pausing only to spank her ass. After a few minutes, she told me to cum inside her tight pussy. This pushed me over the edge and I finished deep inside her. I slid out of her messy pussy and she spun around and took me in her mouth sucking me clean. I got my clothes on and headed out. She hasn't said anything at work about it, but sometimes she gives me a wink and a devilish smile.
