I didn't read the manhwa BUT breaking skin is very unsanitary and dangerous and it takes a pretty decent force to do so... I'd say for the most part it's yaoi magic But, ofc, there's still people out there who like this certain thing so... if it IS done, it should be done with caution~
Its the recent chapter! The character nibbled on his neck and he just went all ah~!
There are certain aspects for everyone to feel pleasure. Some people find it very hot when you feel the others breath on the neck, their teeth, their tongue. Some like hickeys. It CAN cause someone to moan, but it doesn't have to
Does that actually work, the neck biting? Or is it just the magic of yaoi
