Ate my [M] first creampie from my wife [F]

My wife was out for a girls night tonight. She is mid 40s. Small, very cute. Dark hair. History teacher. She got home and seemed quite drunk. An Uber has dropped her off and the driver had beeped the horn. He looked way too happy when I went out there. She had been wearing a short dress.

We went to bed. She pulled off her underwear. I noticed her underwear stuck to her a little bit as she peeled it off. She pushed my head towards her now exposed pussy. I love to go down on her. I started licking her. She was incredibly wet. I started licking her clit. Her juices were dripping into my mouth. Super salty but she tasted good. I made her cum really fast. She clenched her legs around my head.

She quickly fell asleep. I noticed as I was cleaning up our clothes her panties were coated with something. I checked her phone to see where she had gone that night. There was a series of pictures on there showing her with her panties around her ankles and getting fucked. No idea who the guy was. But he was way bigger than me. I’m on the smaller side. I was rock hard as I was looking at these. She didn’t say anything the next day but woke up with a hangover. Should I feel bad that I liked the taste of cum? Tempted to suck a cock now.
