No matter how you look at it, @yano-chan's third time is her first time. First, she is thoroughly stimulated inside by a male actor with a huge penis. Next, she experiences an external orgasm from her usual masturbation and electrostimulation. Then, she is stimulated inside while her clitoris is also stimulated, under the guise of a riding lesson. Finally, she experiences simultaneous internal and external orgasms and continuous orgasm experiences through multiple play, finishing with a grand finale.
