Me and my nephews together.. is this okay?

Once a month me and my nephews get together and have what we like to call a 'jack-off' jam. Basically we listen to music and . We to understand the music more. The setting unusually on a palette on the floor with the lights dimmed and various candles burning. We then decide what album we gon play preferably something old like Elton John or Boy George, and then we lay on our backs and start jackin off. It's a peaceful feeling and you can really connect to the music. I recommend this for girls too.
