After 21 volumes in the series, you'd think the girls would catch on to what that something is about Jack.
It's not his personality -- though he is a nice guy -- it's that 13-plus inches of tube-steak hanging between his legs that never ceases to amaze the parade of petite pussy that comes his way, and it's an interracial formula that continues to amuse.
The set-ups are formulaic (Jack searching for his pussy cat, but finding pussy of another kind, Jack helping a stranded woman on the side of the road... get the idea?), but the sex is what any serious stroker is looking for, and the sex is hot. Standout scenes include April (not the blonde, but a redheaded newcomer), who shows her shaved kitty off to Jack before getting fucked hard, and Hazel, who seems, at times, to be in over her head with Napier's schlong.
Finally, kudos to Ashley Long who takes all of Jack like a pro, and keeps on fucking. Long, who consistently turns in tossable scenes, is pre-nommable as a Best New Starlet.
