First up is Yield – Love+Death by OpenHighHat. The sequence that starts with page 207 (up to page 230 as of this writing) is one of the better gentle F/m insertion scenes I’ve seen. Be sure to follow the links to Imgur for the uncensored versions. I’m not usually a fan of cutaways, but OHH knows what he’s about and this really got me going.
The other is an “abandoned” NFSW animation by SW Riddick featuring a F/f encounter with a shrunken woman. There’s no sound, but it seems pretty clear that it’s either dubcon or noncon. At six-and-a-half minutes long, the little lady gets handled, dangled, licked, kissed, mouthplayed, boob-pressed, vaginally-inserted, and finally receives some giantess cunnilingus. The file is 600MB and you have to download it from Mega.nz, but I assure you it’s worth the bandwidth.
