In the streets, we approach couples who seem close and ask them about their nightly activities! In reality, this is a pretext for the second installment of a project where we seduce and have sex with the girlfriend! This time, our target is Sakisan (21 years old), a couple strolling and dating in the streets. We immediately interview the shy girl and find out that her boyfriend has a cuckold fantasy. Both he and his girlfriend are interested in the idea. We caress her cute face and squeeze her large E-cup breasts, and she blushes but doesn't seem to mind. When we suddenly pull out our dick, she is surprised but starts stroking it in front of her boyfriend... However, she was too embarrassed to do more than that day. But later, we receive a call saying it's okay to have sex in front of her boyfriend, so we call a sex pro and go to a hotel! In front of her boyfriend, we immediately engage in a deep, wet kiss. When we touch her breasts, we find that her nipples are hard! Her boyfriend gets excited watching her breasts and pussy being played with. She looks ecstatic in front of the pro's big dick. Sakisan sucks it eagerly, and when she performs a throat fuck that her boyfriend never does, she seems to awaken to her masochistic tendencies, moaning and wetting her pussy. Wanting more stimulation, Sakisan begs, "I want your dick!" Her usually reserved personality makes this unexpected request, surprising her boyfriend. When we insert our big dick into her pussy, accustomed to her boyfriend's small one, she moans, "Ahh///" in front of him. In cowgirl position, she hits spots that usually don't get touched, having continuous light orgasms. Her boyfriend also wants to be touched, so he strokes his dick while the pro is inserted into her. Unable to resist the pleasure of her cuckolded pussy, he ejaculates on her stomach in front of her boyfriend. The sex, filled with taboo feelings, is incredibly pleasurable! Still wanting more of that taboo feeling, we insert raw! Ignoring her boyfriend's protests, we piston away! Changing positions to doggy style, we have raw sex with another man's girlfriend! Her boyfriend is confused when she enjoys getting her ass spanked. Adding her boyfriend's dick, she convulses and squirts! She rides another man, grinding her hips! It feels so good that we finish with a raw creampie! After the creampie, Sakisan takes a shower to wash off the sweat and cum. Thinking she hears something from the bathroom, we find out she's having round two with another man's dick while her boyfriend isn't looking! After continuous pistoning in standing doggy style, she returns to the bed for more sex! In intense missionary position, she whispers, "I'm cumming, I'm cumming," and we finish with a facial.
