Every time you masturbate to a blueberry girl, your cock and balls will swell up with blueberry juice and continue to grow and swell until it is the size of a horses cock and balls. You will also leak bluebrrry cum from your penis. After you orgasm your penis will go back to normal, but be slightly larger than it was because of how stretched it got. The more you do this the more it stretches over time until it is the size of a horse cock.
