Alright, I will start by saying I don't know if this has been discussed before but I have noticed a disparity in what tags specifically cover here on Fakku, but elsewhere too.
I will list some examples or sets of examples to illustrate my point.
Sex positions in threesomes and group sex:
So it is fair to say that group sex is a popular medium of hentai. These include harems of one guy and many girls to gangbangs of one girl by many guys. However, it is generally been classified under the '
group' tag. However, not so long ago, we got a much requested tag,
double penetration, that act of two or more insertions into the receiving partner (typically vaginal and anal simultaneously), but that begs the question on other acts that are distinct or related.
Spitroast: A spitroast, as I understand it is when the women is having sex with one person while also giving a blowjob to another. This is pretty distinct from DP and may feature in the same chapter with the same or different characters but that is not guaranteed.
Example (but has to be purchased)
Gangbang: So I am not sure where Fakku stands on this term and its implication. But most gangbang scenes now typically include DP, but can also add a blowjob or more, which can definitely exceed the DP tag but fit under 'group'.
Daisychain: The extended sixty-nine with three or more participants, so this is something occurs in some group sex scenes (Twin Milf volume 2 final chapter).
69+1: A sixty-nine with a third (maybe even a fourth) person having penetration sex with one of the people engaging in the 69.
Example Positions that Fakku does cover: The reason I even note this is because there are examples of positions that are tags rather than just actions.
Facesitting: This tag is a perfect example of a postion as it is the act of oral sex but with the person receiving satisfaction straddling the face of the one giving pleasure (usually cunnilingus, but it could be a blowjob too).
Sixty-nine: A sex position where people give each other oral sex at the same time. That could be covered by oral sex or the tags, cuninglingus, blowjob and deepthroat. However, this specific tag explains a position of the sex.
Double Penetration: As previously mentioned, DP is a specific of group sex indicating multiple penetrations of one person by several others.
Actions vs positions: This also brings up an interesting topic of sex act vs sex position. What I mean here as the act can be carried out in several positions. For example, vaginal sex is the act and the examples of missionary, cowgirl and doggystyle are the positions.
Paizuri: A tittyfuck, with the use of breasts to stimulate a penis to cum is an act that can be carried out with the guy sitting down with the girl kneeling in front, or laying down with the girl on top or the girl laying down and the guy straddling her.
Oral Sex: Oral sex can be to stimulate a penis or vagina with a mouth and done in a variety of positions (facesitting, deepthroat, sixty-nine, etc).
So I wonder whether this should be a distinction of future tags that are suggested? I know that I would like a distinct spitroast tag here on Fakku, maybe even the 69+1.
