This amateur line supplies a far hoter selection of Japanese porn than is typically to be found trotting to market even under the "rofessional" banner. Case in point are the comparatively rare girl/girl and anal segments in these three volumes.
In Vol. 9, for example, Minami shows up at the doctor's office and catches a fairly hot condom-wrapped butt-fuck in exchange for all the commendable cock-sucking she and the nurse lay on the filthy physician.
Then, in Vol. 10, which features a nice helping of the patented Japanese penchant for sneaky sex-in-public, Rui is driven around Tokyo, all the while blwing her beau in the back seat. Look also for Yuki's kinky encounter with an ICBM-sized dildo.
Finally, in Vol. 11, Ayoko has her considerable sex toy collection turned against her tight little keister, with multi-orgasmic results.
This is Far-Eastern smut much more in accord with the Western porn aesthetic than is the typical Pacific-Rim offering.
