I was able to rent the VHS of this, and found it disappointing. Rocco's 2001 winning streak, which showed signs of wear with Animal Trainer 6, ends here.
The first scene begins with Rocco, Gabriel Zero, and James Brossman (they call him "Janos" which is probably his real name) hanging out in a restaurant, and then picking up Ellen and Nicole Taylor, supposedly for a photoshoot. Of course this leads to sex, but Brossman is the only male. Rocco and Gabriel just watch, as Nicole and then Ellen get analled. It is a very lightweight scene, and could easily have been any of the countless scenes Brossman has shot for Pierre Woodman, or that Nicole and Ellen have shot for LeCastel and Collins. It didn't feel "Rocco."
The second is really several parts. It is long. It begins with Rocco getting sweaty punching a bag at the ubiquitous spa outside Prague. Monica Sweetheart approaches him, looking for her boyfriend Yanni. Rocco seduces him, and they suck and fuck each other, including a long doggy anal.
Yanni, aka Yann Scott, shows up with Titof and Aneta. He takes Monica away, and in a funny staged moment, Rocco is left meekly protesting, "...but I didn't cum yet..." Yann is soon analling Monica, while Titof and Aneta explore each other. Aneta is the generic pretty blonde who was background scenery in the epic first scene of Way to Love, and she's in the background here too, with no anal at any point.
Rocco wanders around, and finds a friend with an older blonde. He heads to their room, and discovers the maid looking at the couple's sex toys. She's a very pretty young blonde, who looks inexperienced. Rocco tries out the toys on her pussy and ass, and then the couple shows up. The guy takes over the camera, and Rocco has some fun with the ladies. We cut away to Yann cumming on Monica, then back at the room, Monica and Aneta arrive, kick out the other women, and Rocco gets busy with them. More pounding anal for Monica before Rocco cums. The editing was choppy, I assume there's more good stuff on the DVD, but this had to be edited for VHS length.
Finally, Nacho and a guy are hanging out at the same Prague A-framed condo that has turned up in RRP 2 and 3, and where that first scene in Way to Love was shot. They order hookers from an ad, and those arrive in the form of Jessica Twain (aka Jessica Fiorentino) and another girl (a brunette with barbed wire tattooed around her upper right arm, she was really hot in RRP2's first scene). These are two women who can express themselves sexually at great lengths, but they are wasted here in a conventional scene that again wasn't "Rocco." There's plenty of energy and anal, but it is routine. At least Rocco realized how good Jessica could be, in a later-shot but sooner released scene, he truly pushes her in AT6. This was a waste of the talent of both girls.
So from the VHS I'd give RRP4 a 3 out of 5. This could improve with the added footage on the DVD, but Rocco's done much better than this movie. Still, the action is fun and energetic, the women (and men) are easy on the eyes, and it is over 2 hours. Really, the poor grade is a reflection of the high standard Rocco has achieved during 2001. This doesn't measure up, but is worth watching.
