CRUISING for SEX - What's the weirdest thing(s) to get you off?

It's kinda sorted in 2 categories for me.
1: Pre-Covid (Normal Shit!)
2: Covid Era (Until this shit ends... :()

Pre-Covid: I wanted to have a 3-way with my ex & her sister. I played it as a joke so nothing happened, and it kinda was.
However, the sister genuinely hated me until my ex & I broke up nearly 7 years into a relationship (probably still hates me to this day), so Idk why I wanted this.
She was a slut! Not really a problem for me NOW, but I wasn't into that shit in high school. She was also a fucking bitch. I was never gonna work out, but just imagining my ex and her sister playing with my cock, maybe tied up and then getting fucked in every hole... HOT!

Covid: I tried sites like this and Motherless again since... I'm not doing anything, so why not. I got way more interested into cocks and CDs.
CDs are kinda weird for me, but it isn't because CDs are bad (I've talked to a really nice one on here (I fucking love you, orallyours61!). I just don't know what brings someone to do that. If anyone has any answer, please answer them here or just message me.

Now, the question is to you: What's the weirdest thing(s) to get you off?
I might be disgusted or aroused because this site is weird. But bring it on. I'll let you know if I get horny from your weird stuff.
