I was always with my childhood friend, but before I knew it, she had a boyfriend... My childhood friend, who I secretly liked, showed me the clothes and underwear she was going to wear on our first date, without even knowing my feelings! She didn't treat me like a man, so she changed her clothes in front of me, and of course I got a boner! Of course, I found out and it became awkward, but it seemed like my childhood friend was also horny, and there was a stain on the underwear she just bought...
