I don't know if this has been addressed yet or not; I've only been playing TiTs for two months or so, and I'm not about to go through over 300 pages of posts to make sure I'm not repeating what someone else has already suggested.
In Tam-Tam's Bad End, she acquires a vibrating canine dildo attachment for Tam-Wolf and makes the PC his bitch.
I'd like to see the ability to get a similar toy and be able to use Tam-Wolf via your Masturbation options. Maybe include it in the portion of Kara's second quest when Tam-Wolf upgrades himself in the kennel at the pirate base?
There are 17,000 other things that I'd love to see added, but this one has been nagging at me for a while now; ever since I deliberately lost to Tam-Tam to see what would happen.
And I KNOW that the focus for the devs right now is game progression, game mechanics tweaking, and updating/improving/fixing more recent content. Too many times in other forums, here and elsewhere, people seem to like pointing that out, and I just don't think it's appropriate or productive. The name of this thread is about what WE would LIKE to see added. And that's what I'd like to see.
