A woman named Ruri, age 26, finds herself wanting lesbian sex after being surrounded by nothing but females. Her submissive boyfriend, who always does whatever she says, wants her to have sex with a man so he can watch. They meet up at the park where they start having sex right away! She seems surprised but goes along with it anyway. As they arrive at the hotel, she appears nervous despite never having had real sex before. To relax, she gives him a blowjob while using a vibrator on her clit. He gets hard quickly and she starts sucking him off passionately. It feels amazing for both of them until he cums inside her mouth which makes her squirt all over his cock! In return, he fingers her tight pussy until she orgasms violently again. Despite not having much experience with men, she takes control by straddling him and riding him hard until they both cum together. Their passionate lovemaking leaves them exhausted yet satisfied as their bodies recover from this intense encounter.
