I'm a member of the track and field club. A sudden downpour today forced us to change practice indoors. We usually practice on a large athletic field, so I never thought the sight of girls in racing bloomers was sexy, but today we're indoors, so we're so close to each other that it's dangerous! In the end, I'm a virgin and I couldn't help but get a boner when I saw the girls' protruding butts! Instead of backing off, the girls were curious about my dick, so they chased after me as I ran away and forced me to insert it! However, my first time having sex was so good that I couldn't be satisfied with just one time! It felt so good, I wanted one more! But it wasn't enough. And one more. "I've had enough..." the girls on the track and field club ran away, so now it's my turn to chase them all over the school, cumming inside them repeatedly! It won't end until I'm satisfied!
