Matt starts to wander around the massive body. he walks for hours, putting his hand to his balls every few minutes to punish Tai. He reaches the cavern of Tks shorts. Suddenly there is a huge rumbling as Tk shifts his weight in his sleep. Matt was pitched foward and landed between the legs, inside the opening.

After checking Tai is still under his balls, Matt assess the damage. He wasn't hurt but he could not climb the huge leg. It was too big.
He looks back but the massive feet of Tk are stretched over a cliff. Being so big, Tk reaches each side easily, but since the only way back is to climb his toes, and they were too far away, he had to press foward. Forward into the briefs.
