Aaron, the timid twin, has always been curious about Zach's size but never acted on it. Today, Zach offers him a chance to explore, and Aaron tentatively takes it. Zach's cock, thick and long, fills Aaron's mouth, stretching his lips wide. Aaron struggles to take it all, gagging slightly, but Zach's encouraging moans spur him on. Zach pulls out, pushing Aaron onto the bed and spreading his legs, revealing Aaron's tight, virgin hole. Zach lubes up, rubbing his cockhead against Aaron's pucker, making Aaron squirm in anticipation. Slowly, Zach pushes in, feeling Aaron's tight heat envelop him, making him groan with pleasure as Aaron tentatively enjoys his first taste of gay sex.
