"The only way you'll get a butt as big as mine is if," as Ben was talking, he slipped his pants down, revealing his underwear-clad ass. "...you put your penis in my butt." Blake was surprised. He'd always heard that putting your penis in a butt felt really good, but he thought boys were only supposed to do that with girls. He really liked Ben's butt, though, so maybe this wouldn't be wrong. Maybe what matters is that you like the butt you put your penis in. "Really? Are you sure?" Blake asked. The getting-a-big-butt part was still weird.
"Yeah of course I'm sure! You trust~ me right?" Ben asked, wiggling his butt and making it jiggle. Blake gulped, and he quickly got a boner. "Man, even if you are lying, I still wanna put my penis in your butt," Blake admitted, starting to strip. Ben smiled, and stripped as well.
Both boys were completed naked, and Ben had moved to the couch, bending over and wiggling his now bare ass. Blake really loved Ben's huge ass, especially because of its hugeness. He joked before about his butt cheeks being beach balls, but that really wasn't too far off. His butt cheeks really were about that size each, and as Blake grabbed them he almost drooled. He rubbed them around and stretched them apart, looking at Ben's clenching butthole. The thought of having an ass as big as this was quite enticing, and that plus Blake's desire meant he couldn't help himself. He grabbed his penis and guided it to Ben's butt, swiftly thrusting it inside. The intrusion elicited a moan from Ben, and Blake started to thrust. The two boys fucked for a while, and Blake's small hips were sandwiched by Ben's cheeks every time he thrusted.
Eventually, Blake's pleasure built until he released inside of Ben's butt. He pulled out, lying down on the couch.
"Hey, didn't you say I'd get a big butt?" Blake said. Ben responded...
