First, Cheating alert!!! Plz keep in mind when u r watching. Plz self insert to the bad guy, which is the person who goin to cucked the BF if you don't have cuck fetish.

What I wish: the sex scene can be more intense, faster movement.

Good point: Although the movement is moderate speed, the sound and the frame/picture do express the intensity, 1st ep blowjob and the rest of s*x scene. VA is very expressive/impressive, face expression/reaction is very nice. Besides, I like certain scene where it stress on they cucked the BF. Hv 2 eps longer s*x scene if compare to other T-rex products.

Watch it ...
