[Yamome] Tandeki no Otori (Badi No.106 2014-12)

Gin, a one-eyed rickshaw driver built like a workhorse with a hairy, hypersensitive chest that lactates when milked, gets picked up by two wealthy brothers with very different levels of experience. Under his big brother's steady coaching, the shy younger sibling learns exactly how to work Gin's nipples and ride him raw, until the lesson escalates into both siblings sheathing themselves inside the driver at once while he protests his ass is going to break. What starts as a rich boys' toy session ends with Gin soaked in their cum and formally promised to both brothers, who admit they could easily get addicted to his body.
