Amy was on her way to the beach when she stumbled upon some iffy place and overheard some stuff that wasn't meant for her cute pink ears. Not so surprisingly, she was quickly snatched by some thugs. Poor Amy knew too much for them to simply let her go and, since her captors were big fans of classic DID scenarios, they decided to deal with her via tying her to the rail tracks. Seeing as the tracks were in the middle of the desert and Amy's captors were true gentlemen, they left her only in her bikini, which she had with her, so it wouldn't be too hot for her :3
Do not worry, Sonic will still save her and she'll be fine :D
This was a fun request. Always enjoy drawing my fave gal tied up and gagged :) I hope you like it!
