My occasional fuck buddy posted a couple of stories on here recently about some stuff we've done, however this posting relates to something else. I work as a handyman, andin the run up to Christmas I was called by one of my pretty regular customers to fix a problem with his en suite toilet. He said no one would be home and the back door key would be under a pot on their patio. Couple of hours later and his toilet is in bits on the end suite floor as I fit a new siphon. I hear the front door close and just assume whoever it is knows I'm there. Sure enough I soon hear voices downstairs...one is clearly his wife but I can't place the other voice. No more than 2 minutes later and I hear them coming upstairs giggling. The end suite door is slightly ajar and I see them come in....the guy naked and my customers wife semi naked. Fuck. I kept quiet, pushed the door too a little, but could see well through the crack of the door. They were not wasting any time and she hungrily sucked his rod. I'd met her a few times but thought she was a bit dull and shy. His wrong was I. Both nipples pierced and a few tattoos which included an arrow on her lower stomach pointing to her cunt, and the word slut inked across her arse. Not only that but this was porn sex. She was the ultimate bitch on heat. Once he was rock hard, he had her on all 4s and slid into her cunt, calling her every name on the sun. It didn't take long before he then went for her arse, upping the pace and now frantically ramming her... All the time spanking her arse hard and calling her names. It was clear he was close to cumming and the dirty bitch turned round, taking his cock back to her mouth, sucking him dry as his arse tightened and he came. With that he left the room, not even saying bye to her and I heard the front door slam shut behind him as he left. She soon recovered and I panicked, realising she'd probably freshen up in the end suite. She was texting a fair bit and seemingly a bit pissed off, eventually calling someone "he's gone, where the fuck are you...........OK see you in a a minute" obviously she had not finished. More texts, and around 15 minutes later the doorbell rings. She jumped up and ran downstairs. I was tempted to leave, maybe hiding in a spare room but curiosity told me to stay put. Sure enough she was soon back, this time with a lad aged around 19, and tthislad needed guidance, with her talking him through exactly what she wanted him to do to her. Basically he started of my giving her oral, before she spent ages rimming his arse. All this time I was wanking furiously. She kept having to stop because he was on the edge of cumming. Eventually she climbed on him and rode him hard. He kept cumming but was still clearly hard. There must have been 20 minutes of that before they were both done and they left the room. I'd cum twice, and not long after they went downstairs I heard them both leave. I had a quick look through the bedside cabinet and sure enough a nice collection of vibrators, o one of which was soon up my arse as I came for the third time. I see her around town a fair bit, looking like butter wouldn't melt. We really shouldn't judge a book by its cover
