The boobs can never be too big.
It's hard to find something new to say after playing so many of these.
It's pretty much up to your standard, I'd say. I appreciate the varied sound effects and am happy that the multiple girl/RPG style has become your standard format. The gang-bang was a clever idea and I liked the mouth-fucking.
More over though, I'd say it's just a case of taste while I didn't like this one as much as the Detective or Ocean Cruise one. I didn't find the girls as cute or hot and the positions seem odd to me. The elf and the queen scenes are easily the best.
