Hi! My request this time will be placed under a cut...

The specific fic I'm looking for started as either wee!cest or teen!cest I don't remember exactly. Sam wouldn't stop sucking his thumb no matte what John tried. Eventually instead of sucking his own thumb he would suck Dean's and that eventually led to him sucking Dean's cock. When they got older it turned into wincest with bottom!Sam and I'm pretty sure it had some water sports thrown in! I hope you can help me find it!

Next I'm just looking for any for any wincest with bottom!Sam that contains either; dirty talk, enema, fisting, watersports, name calling, bdsm, toys, rape fantasy, knotting, cum inflation, breathplay, daddy!kink or bestiality. Oh and I would prefer if these were is season one/two or preseries but that is not a requirement.

Thank you for any help!
