Yankee Shion, who looks squid and is actually de M, and Yankee Shihime, who looks serious and is actually de S, is an honor student ... A gap lesbian story of two people who have a propensity contrary to their appearance! From the day when Rena, who holds the secret of Shion, defeats the Yankee with a vulgar kiss and tongue technique, ferocious lesbian training begins! When you play with the sex toys you got, Shion, who obeys her crotch while resisting, greets each other for pleasure! [* There is some disturbance in the image and sound]
