milf sonic and neo metal sampling each other's milk as both of their big tits are pressed together all while being fucked/impregnated by both chaos and shadow together
Metal: As you can surely taste, my teats secrete a perfect engineered nutritious fluid for my young to grow big and strong.
Sonic, taking Metal's tit out of his mouth: Tastes like a protein shake, and not a very good one.
Metal: Taste is subjective, my loathsome copy. You probably wouldn't know what something healthy tastes like considering the garbage you shove in your mouth to create the sugary slop you dare to call "milk".
Sonic: Yeah, but mine still tastes better.
*Metal sucks on Sonic's tit to taste it for himself*
Metal, still chugging from Sonic breast: ...well mine is still better because it's healthier and-
Sonic: Yeah, yeah, yeah. Talk about how healthy your milk is all you want, but the fact that you're still drinking mine shows what you really think. ...I've got an idea for the best of both worlds.
*Sonic puts both his other nipple and one of Metal's nipples into his mouth, drinking both at once*
