This is YrSa's Lovers Lab page: They have very good BDSM and other animations for download, as well as a list of "required" mods which includes links to a few dildo packs. Here's the one to a download of Noir and Dark Sims' Double Dong decor set: https://noiranddarksims-adultworld.blogspot.com/2017/08/ts4-double-dong-decor-set.html?zx=8a99275e912b8aa9 This pack is working for me with YrSa's animations, but I haven't tried it on others yet (and the double-dong that shows up is purple, not black, FWIW). I hope this helps! Let me know if that set works for you. Also, I would love it if you would link me to the animations you're using. I'm always on the lookout for good F+F content. Have fun!
