Caught my senior work colleague

I'm nothing special in looks but doing okay career wise. at 32 no girlfriend a rarely dating. Late one afternoon almost time to go home, everyone else were heading for the door. I needed a notepad, so I went to the storeroom to get one opening the door caught a female colleague 47 sucking off a younger man turned out to be a rep. Shocked at the sight, just grabbed a note pad and left. Short time after the very worried colleague approached me, she was married to a high manager 58 in the company. So, I'd no intention of telling anyone of what I'd seen, but she was afraid I would tell her husband. She was desperate and offered to doing anything if I kept my mouth shut. Going on to tell me her husband wasn't doing anything in the bedroom anymore and he was either playing golf or doing business. Lonely she got relief wherever she could, adding her husband was away at that time as well. Reading between the lines, I thought she was offering me sex. She was and as I wasn't getting much if any myself, I took her up on her offer. She came to my apartment and stayed the night, leaving early after another fuck to change for work. Her husband got back that day so no repeat that night. But he left again Friday for a weekend of golfing, I wondered if he was fooling around himself. I would find out he wasn't later, anyway his wife came to apartment stayed till Monday draining my balls. For several months that was my new lifestyle fucking my colleague. Like they nothing stays the same forever, her husband got promoted and they moved away. I was shocked as a parting gift she had her husband promote into her old job. I must've satisfied her enough to get the promotion, or it could've more insurance on me keeping quiet.
