Straight-laced and curious, a guy finds himself in a compromising position with his brother. As they share a small space, his brother's hard, uncut cock becomes impossible to ignore. The straight guy, driven by a mix of curiosity and horniness, tentatively reaches out, wrapping his hand around the thick shaft. He hesitates, then tentatively licks the pre-cum beading at the tip, his brother's audible moan spurring him on. He takes the cock into his mouth, tentative at first, but soon finding a rhythm, exploring the unfamiliar yet exciting taste and texture.
