Why do their pants can easily take off by others. Do their pants have no garter or zipper and button?

This is actually wrong. It's actually all in the underwear. The underwear subconsciously generate movement that slides the pants at any sexy time moments when temperatures are so hot that both uke and seme are instantly wet in the eyes, testicles, anus and skin. It's a skill for only gay underwear though, don't try it with other underwear,
I was like, wow, a possessive seme? This one's my cup of tea then a cult showed up lmao
