A woman named Ruri, age 26, finds herself wanting lesbian sex after being surrounded by nothing but females. Her boyfriend wants her to have sex with a man so he can watch, and she agrees! 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. In return, he pleasures her with handjobs until she cums multiple times, squirting all over him. Unable to resist any longer, she straddles him and rides his cock like a pro while moaning loudly. Despite having little experience with men, she takes control and deepthroats him until he cums inside her mouth. Afterward, they collapse together in exhaustion as their juices mix together.
