Caved In by Robotnik_9

Sonic and the gang visit one of the biggest and most ancient caves in all of Mobius for a Summer activity. What started off as a harmless, self-guided tour, soon became a danger to their lives. The gang becomes split up, as the roof begins to cave in. They must go on a journey to find each other again and find their way out, without cell phone reception, or a map. When Sonic and Shadow get stuck together, they may find that they work better together than they thought, perhaps in more than one way.

{Sonic Boom Universe} 《Warning! Boy×Boy, swearing, violence, potential smut[Bottom Shadow], suicide\cutting, mentions of rape, and a bit of Manourge.》 ~ "You had you're way with me, now go." ~ "Just, leave me be!" ~ Sonic The Hedgehog, the speedy hero everyone knew and loved, was depressed. He hated his body, and everything to do with himself. No one knew the real him. That is until a certain ebony hedgehog walks in on one of his daily nightmares, and gets slightly worried. Shadow The Hedgehog, the edgy one, the one who was covered in darkness and darkness alone, holds a painful past in his hands. Despite not knowing it the two are both the same, slowly withering away. But just when Sonic gets the help he needs it may be to late. ~ "I'm not openly Bisexual yet." ~ "Wait! Shadow's gay!?" ~ "Shh, it's ok sweetheart." ~

Sonadow - The Island by Sonic-Fan4ever

[ALL CHAPTERS EDITED!] When a scientist announces, that every male mobian hedgehog is either an uke or a seme, nobody really cares. But when Eggman of all people reveals, that Sonic is an uke, things... SONIC changes. When Sonic mentally breaks down and is a mess, it seems like a miracle, that people show up who know how to treat a nervous uke. However, this is far from true. Those people have totally different intentions and they drag poor Sonic in this mess. The only friend he has in this hellhole called 'the Island' is a black and red hedgehog, who seems the only one not interested in raping him... Warning, might contain quite heavy stuff for some people!
