Fics I'd recommend

I haven't been on FiMFiction all that long yet, but I've been guided to, and found some lovely work in that time.

http://www.fimfiction.net/story/1422/romance-reports Twilight Sparkle wants to make a move on Luna, but the nocturnal princess wants her to actually get some experience under her belt first so the gulf between them isn't quite so vast. Twilight's assignment? Go forth, find sex, romance, and love, reporting her findings back. ( Very well done, 185k epic. Emotionally charged, intelligently-told, sexy and steamy as can be. )

http://www.fimfiction.net/story/27874/Xenophilia A lone human stranded in Equestria finds his friendship with Rainbow Dash blossoming into something much more serious, opening his eyes and heart to a world fully as strange and wonderful as the physical land he finds himself in. ( Touching, well-crafted, creative, and wonderfully sensual. )

http://www.fimfiction.net/story/60371/gentleman-for-mares Another HiE tale, the protagonist in this series is far from alone in Equestria. The human world has a reliable connection with the pony's realm, and steady commerce has commenced. He happens to be an 'escort,' helping address the severe mare/stallion imbalance by bringing pleasure and/or relief to mares in a way only humans can, with clever fingers and agile bodies. ( Far from being just a series of sexcapades, there's good world-building here, solid character development, emotional involvement, and creative original touches along with the expected eroticism. )

http://www.fimfiction.net/story/19247/green Rarity has pined for Fluttershy for ages, but has never been able to admit her feelings to the demure pegasus. The frustration mounts until the unicorn thinks to confess her love by anonymous letter, testing the waters as it were, as well as clearing her mental buffer of hoarded feelings. What if she's rejected? What if she ISN'T? Oh, oh, oh, I think I need to lie down... ( Another marvelous romance with its ups and downs, keeping you on the edge of your seat. )

http://www.fimfiction.net/story/58441/written-in-dust A human urban explorer is pulled into a post-extinction-event Equestria, the world in ruins, and his only way home is to have his consciousness thrown back in time, into the body of a pony who lived just prior to the disaster that nigh-sterilized a once-wondrous world. ( One of the best plots I've seen on the site. Very well-executed. This would make a tremendous fan-film if enough quality people could be pulled together for a live-action + animation effort. But that's beside the point! No naughtiness in this story, but don't let that stop you from reading it. )

I hope you love these as much as I did, and if you think you know others I'd enjoy based on my picks here, please share the links in your comments!
