I don't need a girlfriend, but I want to have lovey-dovey sex. I want to go on a romantic date, but I don't want to be tied down. It is difficult to find such a convenient relationship. Natsuki is older than me and will contact me as soon as her work is finished. We contact each other almost every day, tell each other that we like each other, and have sex live, but we haven't explicitly talked about dating. Is this a sex friend? she?
