Justin Matthews and Liam Riley clicked right from the beginning. And you can immediately see why -- Justin is a more simple-minded country guy while Liam's a bubbly big city boy, a walking exclamation point! Even physically, Justin's a taller, tan blond Adonis while Liam is a slightly shorter, brown-haired pup in training. A perfect Yin and Yang is what you could call their chemistry, and that always leads to some explosively hot sex.
