Big and beefy Riley Mitchel is back at the studio and he's on a quest for what he calls a challenge. And, by challenge he means a big cock! Riley isn't new to big cocks, he just likes to see if he can fit them in his big bubble butt! He's had around 10 to 11 inches in there before but he can't seem to get enough. So, he contacted Caruso to see if he could help out. Not only was Caruso thrilled to help out, but he already had the perfect person as well as cock in mind!
