In a dimly lit, makeshift clinic, Isaac, a curious and eager twink, finds himself face-to-face with Brian's massive, throbbing cock. Brian, playing the role of the doctor, has Isaac strip down and lie back on the examination table. Isaac's eyes widen with anticipation as he takes in Brian's impressive length, then eagerly opens his mouth, swallowing Brian's shaft inch by inch. Brian groans in pleasure as Isaac's warm, wet mouth envelops him, using his eager tongue to tease and pleasure every inch. The room fills with the sounds of wet, sloppy sucking and Isaac's muffled moans of delight as he deep throats Brian's thick cock.
