Sailor Mars just got back to her shared studio after saving Sailor Mercury's boyfriend. Mercury's boyfriend is so impressed with how Mars saved him and then the conversation moves in a more flirty direction. It turns out that they both have crushes on each other. Mars tempts him and asks if Mercury really gives him the attention he needs because we all know how Mercury buries herself in her books all the time. Mars makes the move and kisses him. Mercury's boyfriend is apprehensive as he know Mercury is supposed to come over to the studio later on. He moves to the other side on the transparent colored inflatable rocking lounger. Mars crawls on the inflatable lounger, seducing Mercury's boyfriend and pulls out his cock to suck. Mercury's boyfriend has given in to Mar's warm and irresistible mouth. It just feels too good! Naturally she makes him hot so he has to take off his clothes. He gets on the inflatable lounger and she starts riding his cock as he feels up her legs and powerful ass. The camera zooms in as he spreads her ass and plunges his thick wet cock in and out of her. The sight is irresistibly erotic. She rides him cowgirl style for quite a while and then Sailor Mercury shows up. At first Mercury peeks out of the cherry blossom screen. She is shocked and mortified to see Sailor Mars straddling Mercury's boyfriend's cock. "I can't believe you're fucking my boyfriend!" Mercury says. Mars and Mercury's boyfriend are oblivious to Mercury's presence and continue fucking and moaning in pleasure. Mercury has no choice but to sit on her inflatable transparent blue chair, fingering herself while they fuck. In desperation, Mercury tries to show off how sexy she is to get her boyfriend to notice her, but he's bound by the pleasure of Mar's hot fiery pussy. Eventually Mars switches positions to ride Mercury's boyfriend reverse cowgirl. Mars finally notices Mercury and says " Oh hi Mercury I didn't see you there," as she giggles. Mar's says some more humiliating things about Mercury while fucking Mercury's boyfriend. Mars really enjoys cucking Mercury! At the end Mars is being fucked doggy-style while facing Mercury. They all start to cum at the same time with sexy orgasmic moans. Mars laughs at Mercury and says " Your boyfriend just came in me!"
