Go visit your best friend Dave

You decide to head over to your friend Dave's. He lives down the street and the two of you grew up together. You remember that Dave has always been there for you, he even got you your first kiss. It may have been with his twin sister Suzie, but it was nice. Before you realize it, you are at Dave's door with a massive hardon. You almost stop and wait until your boy goes down, but something drives you to reach for the doorbell.
