My [21] bf plans on spending valentine's day with his new lover

This is an update to my previous post

They have been talking almost all the time since my bf invited him to our house. He spends all the time chatting with him on discord. They also have been meeting almost everyday (always ending with them playing with each other).

My bf said to me that he wants him to be his valentine this year, and that he plans on inviting him today to stay the night in the bedroom with him. They are constantly hornychatting about what they would be doing the whole night with each other. 14th of march is very important to us since it's the day we decided to be together 3 years ago, and I can't describe how much it turns me on, knowing that his lover (which doens't know we are together) will be here this day to claim him as his new bf while I lay on the couch and probably hear them fuck so hard I would be able to hear the bed crack 🥵
