First you almost always have a choice what kind of sexual interaction whant to have so you can practically go without even see foot fetish.
Second there are soo few games with foot fetish and even less with good one, so dont you dare to destroy that. There are plenty of other games without foot fetish.
Yeah, I get that your into it, I'm not saying take it out, mostly as you say it's completely optional.
Although, that does bring a funny ass thought/scenario into my head...Lol!!
How about this, after a nightly Mom visit, and you choose to mix it up with the ole foot fetish. The next day, you notice something wrong with your penis....you know itching and burning. Not wanting to say anything to your Mom about it, you go to your Dad and ask him what it is. He sends you to the doctor, and you find out you have Athlete's foot on your cock......Lol!!
Before you can start the lotion treatment, Mom comes and pays you a visit. Then a couple of days later, at the dinner table Mom say's she's just come from the doctor's and has an interesting problem. That she's somehow has Athlete's mouth, and can't figure out how that could have happened...…….Lol!!
The best part is, the Dad just scratches his head and tries to help, by seeing if he can put his own foot into his mouth...……….Fuck! that's good entertainment right there...…...Lol!!……………………...Peace!!
