Today, I invited Ria-chan, who is both my teacher and friend, to my place to throw her a birthday party. It's been three months since I started going to the gym, but honestly, my real motive is that I've been after Ria-chan. Her face and body are exactly my type, and the fact that we've gotten close enough for me to invite her over feels like a miracle. Since it's her birthday, everyone gets into the spirit with a rare cheat day, and Ria-chan gradually becomes bolder. Her face turns red, she gets really into it, and she's just too cute. When I went to the bathroom, for some reason Ria-chan came in and said, "I'm crashing in... wanna kiss?" While I was wondering if I'd forgotten to lock the door, she started playing with my nipples and dick, putting me in a dangerous state. Eventually, she even started giving me a blowjob, and said, "Licking you got me excited... you can just cum like that," and she milked me dry. Ria-chan's true nature is way too lewd. I was feeling kind of floaty myself, and I thought maybe it was a dream, but before I knew it, I'd fallen asleep. When I woke up to a nice smell, Ria-chan was on top of me and said, "You're finally awake...♪ Wanna continue where we left off...?" It wasn't a dream. Yes, yes, yes, yes—. What's up with her? Is Ria-chan sexually frustrated? She's never like that when she's training me. I hope she doesn't forget tonight. My next gym appointment is next Thursday, so I'd like to ask for another lewd joint training session after that.
