I am a 20 year old male. 6″ even, and rather well-endowed where it counts. My girlfriend of 2 years is 18 and is also endowed in her chest. She is an amazing girl and I love her to death. Her single mom had her when she was still 16 and in high school, making her 34. She is a gymnast at the local gym so she is very much in shape. Often my girlfriend (we’ll call her “J”)works late so I will come to her house early and wait for her to get back so I can see her. During these times, her mom (we’ll namer her “A”) and I will talk about really anything. After I’d been around for a while and we got very comfortable with each other and were able to talk about anything with each other. One day, “A” told me about the man who left her when he found out that she was pregnant and how she was crushed. She also said that she saw how “J” and I are so happy together and says that she imagined a guy like me being the kind of guy that she wanted to be with. Someone who can make her feel special and just listen to her like I do. After a pause, she leaned in and kissed me quite passionately. Long story short, “A” and I ended up sleeping together. She was magnificent and knew exactly how to make it feel great. That wasn’t the only time. I began coming over sooner every time so that we had time to do it before “J” got home. Sometimes if I would stay late and sleep with “J” I would sneak over to “A’s” room and sleep with her before actually going home. Yesterday after “A” and I did it, we talked about how we both felt about the situation. She said she wishes she could have me all to her own so we could get married. I told her that I genuinely cared for her and that I wish I could too. She told me that she loved me and I said it back. I meant every word of it. The problem is that I feel that way about “J” too. I’m not sure what to do. Advice would be appreciated.
