>>121734It was Clannad. My first eroge was kemono musume no sodatekata because I was going through a late horny phase where I downloaded a bunch of eroge to fap to and that was the first one that worked.
It has an early sex scene that caught me off guard. The experience was so immersive, it made my legs shake, it was thrill the first time.
IxShe Tell is my favorite among all of them.
