I have been in a relationship with my boyfriend for roughly two years, and he moved in with me and my female university friend, who is also my housemate, last year. Typically, we all gather to watch TV or movies or Twitch in the evenings, and initially, my boyfriend and I would occasionally share kisses and explore each other's bodies on the couch while watching a film. My friend was completely unfazed, so we eventually kept pushing the limits of what we could do together. Frequently, it would become so intense that we’d have to leave the movie and rush upstairs for intimacy. We can be pretty noisy in bed, and once as we were getting up, my friend suggested, "Why not just have sex on the couch?" "I can hear it all regardless."

My friend and I have consistently had candid discussions about our sexual experiences, including conversations about my boyfriend's physique and our activities in bed. The night prior and things like that happened right in front of my boyfriend, so we thought "why not", and I sat on my boyfriend on the couch while my friend was around 6 feet away watching TV, and afterward we simply continued watching like nothing occurred. We began doing it increasingly often, and it has reached a stage where it's become entirely normal for my boyfriend and me to spontaneously have sex on the couch, occasionally entirely undressed, while my friend sits in the armchair right beside us. Lately, my friend has begun to masturbate while we engage in sexual activities in front of her, which really excites me. The most intense part is when we casually discuss random topics while I'm having sex with my boyfriend, and I’m moaning and gasping mid-sentence as I speak, yet my friend responds like everything is completely normal.
