A good story , with a horny twist , we have a regular baby sitter Jilli , shes 20 in uni , a lovely girl a bit of a free spirit , she was loyal to us and we could trust her. Anyway the last few times she was baby sitting , i was thinking that she was snooping around the house and i thought some of stuff had been moved even things had gone missing. Without telling my wife i installed a cameras in the front room and upstairs. My thoughts were wrong , after rewatching the coverage back , she wasnt doing anything wrong , she did spill a drink on her top and removed it , down to her bra which was as it. But that changed in early February this year, we went out with friends , good fun , good company but Kate my wife said she was having “monthly stomach cramps” she said she was going home and told me to stay with our friends. I stayed on for a overdue catch up with our friends , i messaged Kate she said she was in bed with her trusty hot water bottle. When i got home , Kate was a sleep . Nothing else much happened , i went to work and we carried on as normal. I removed my spy cameras and took them with me to work , i was going to wipe the memory from my camera, just checking the footage , i noticed the night with the baby sitter and Kate arriving home , i was expecting Jilli to leave , but they shared a cuppa and were sitting on the couch , there was a bit of touching then they started kissing , with a open mouth , i watched as they kissed , then undressed , they were naked and exploring their bodies with their mouths , it was so horny , they got into a sixty9 the image wasnt the best but then heads and faces were enjoying each others pussys. This wasn’t their 1st time they were well into each other. I can’t lie I locked my office door and knocked one out. There was more kissing and fingering play , they got dressed and with a full on kiss , Jilli left. My head was minced thinking how long had they been having fun together. My wife was having a girl on fling with our baby sitter .....is it an affair should I be angry or just use the clips as wanking material. I always thought we had a good sex life , and i never knew she was acting on here bi thoughts. Should I talk to my wife ? or say nothing ?
