"Tittilating Tails Teases Your Tip," "Sonic the Hedgehog Sucks Cock & Balls for Rings to Buy Chili Dogs & Knuckles," "Vanilla's Chaotic Bind," "Hedgehog Orgy," "Meeting Your Heroes," "Sonic Transformed" series, "Sonic Porn Game," "Babysitting Cream" ren'py edition, "Sonic Adventure XXX," "EndLust Chaos," "Mobian Pimp," and all I did was type
sonic porn game into a search engine. Some of these are even on this site.
