Surrender - Bill's bigger than him anyway.

As Bill's weight landed on his chest, Jason decided not to struggle. Lean Bill may have been, but his frame was taut with muscle and Jason knew he was no match for the older man.
"Yes Sir," he murmured as he leaned forward, letting his tongue touch the hot, twitching rod before him, savouring the taste of Bill's precum. It was sweeter than the filling in the pastry, and he soon took the entire head of Bill's thick, uncut meat into his mouth, eagerly sucking up the creamy nectar.
"Oh yeah kid, that feels great," Bill groaned appreciatively, his free hand tangling in Jason's hair and his hips slowly pumping his cock in and out of Jason's greedy mouth. "I've wanted this for so long...so much better than I imagined..." Bill smiled as he glanced down at Jason, wisps of his long blond hair framing his face where strands had come out from his ponytail. "I've seen you watching me all summer, gazing at my body, lusting after me...rearranging your dick when you thought I wasn't looking..."
Jason whimpered around Bill's cock, the farmhand's voice sending hot flushes of desire coursing through his body. Tugging against Bill's grip he tried to free his hands. He needed to touch, needed to stroke...
Bill's low rich laugh was music to his ears as the cock in his mouth was pulled back beyond his reach. "What's wrong kid?"
"Please Bill... I need... I want to... I'm so hard..."
Scooting his body back, Bill ground his ass against Jason's denim encased cock, causing him to moan. "Well we can't have that, can we?" he said, and before Jason knew what was happening, Bill had turned around, his cock and balls swaying above Jason's head as his hands undid his belt and jeans, tugging his cock from the confines of the white briefs within.
"Bill..." was all Jason could groan out as the man's hot mouth encircled his cock, skinning back the foreskin that had sat so tightly around the head. A splatter of precum hit his cheek and he scooped it up with his finger, bringing it to his mouth for a taste. Awash in a sea of pleasure, only one coherent thought managed to stay in his head. Bill wanted him, and he wanted Bill... and Bill was right there, above him, open and inviting to the touch...
