Been together for 3 years she promised me she was not and would not be with anyone else more than a few times I thought I smelled cum scent when we had sex. Once was even at her mom's house she told me to stop by as we did not live together. She was super wet I thought she was just excited to see me. But eventually I caught some text messages and she admitted that many times he would have sex with him and then ask me to come over and have sex with her or go down on her and she would just give me a handjob. She would say she was sore from using her toys. The time at her mom's house her mom even heard us and her mom knew she was with her ex before me and after I left she sent me a message saying yeah my mom heard us and I said but did she say she said she just looked at her and smiled and said her name like a mom would. Lol so her mom knew and must have been supportive and she didn't say anymore just a smile.
