Open Question: Is masturbating (ejaculating) to feet lust?

[feedcrawler]

So when i turned 14, i learned how to cum, and it felt very good; it stopped the sexual tension that i had when watching feet porn online. Along with that, i have a unique foot fetish. So when i masturbate i cum to other women's feet that were from online, but i am not actually online, the feet are in my thoughts; this method actually made me stop watching porn! But lately a concern has come up to me. When i cum to other women feet, is that to be considered lust? Sense i am a christian, and i learned about lust; it is technically having sex with another woman in your thoughts. I know masturbation is not a sin, but lust is. So is cumming to other women's feet when masturbating a sin, but yet your not actually having sex with a woman, but it does involve masturbation and other woman's feet.
