My boyfriend has a female best friend. They’ve known each other since high school. They have a bond that even I, his girlfriend, can not come between. They don’t filter any thing from each other. He would prioritize her before me. I didn’t think too much about it, but I was wrong. I should’ve thought about it. All the late night calls they had. All those moments when he went to take care of her when she was drunk from a party. All those times when she went over to his place for movie nights. I really should’ve thought about it. I know it is wrong and I should stop this chaotic relationship, but I cannot. I enjoy it. It all started when she started to tag along with us for our dates. The first time she hangout with us was during a dinner date. He picked her up to join us for out dinner date. He told me to go sit in the back because his bestfriend only sit in the front seat. When she sits there, they occasionally hold hands while he was driving and he would grab her thighs and squeeze it too. This was normal for them. It is normal that they hug and hold hands occasionally. That night something spark in me. I was jealous. He never grab her thighs before. I didn’t say anything about it. When we got to the restaurant, their legs were crossing with each other under the table. And they were holding hands with each other over the table. This situation made me upset and jealous. But more than anything, I quickly realize that I am enjoying this. That night, he said he will drop me off first. After he dropped me off, I realized that I left my phone in his car. I drove to his place and notice that his car is already in the drive way. I went inside his house and heard them talking distinctively in his bedroom. “ I wanted to cuddle tonight.” She said to him. “ I know and I’m in always here whenever you feel lonely. “ he replied. “ remember in high school when we first cuddling like this?” She asked. “ yes I always think of you whenever I cuddle with someone else. Ha, even with my girlfriend too.” He responded. “ what about when I sucked your dick?” She asked. “ you’ll have to remind me what it feels like, then I will tell you. “ he laughed. I peeked into the room. I saw her getting up from the bed. “ if you want to help with your boner, you could’ve just said so.” She said. “ I know you want me to suck you more than anyone else.” She continued as she took off his pant. I was mad then jealous. And wet. I saw how she suck his cock. I saw why she was favored by him. I left his place in silence. Once I got home, I used my vibrator and came a lot. I kept silence about what I found out.
