バディの背中の後ろの秘密のセックス

Our buddy is visiting for a few days and since we are all adults we can do things on our own from time to time. For example, our buddy currently playing something on computer and we were just out and for an Outdoor Date. But now that we're back and our buddy is still so engrossed in his game, we just had to annoy him a little and fuck right in the same room behind his back. We know our friend too well and actually know that once he gets really engrossed in the game, he no longer notices anything around him. And he's so relaxed and open, he doesn't do anything about it. my boyfriend and I test it to the maximum, or rather to the orgasm. I'm a little nervous, but let's see what happens when I slowly open the door.
