Kijima-senpai teaches her junior how to have sex properly. Her angelic smile turns into wild, bone-crushing cowgirl sex that leaves him addicted and unable to finish with anyone else.












I can't get enough of this slender, flat-chested body. Plus, the natural hair—she was such a great actress.
Airi's expressions are at their best and her eyes sparkle the most when she's with Yuta Aoi. Although Yuta is officially one year older, the dynamic works perfectly. There are three actual penetration scenes—the hotel, the restroom, and the office during the day—and she smiles throughout, just as the title suggests. There's a lot of cowgirl position, and the cycle of smiling, moving her hips intensely, reaching ecstasy, and smiling again is quite arousing. Yuta is well-endowed, which seems to feel good, as Airi's bottom is slightly flushed in the first scene. In the third scene, she's in a situation where she can't make noise, so her suppressed breathing sounds like hyperventilation, which is very erotic. I couldn't see the penetration well in the second scene, but it got intense once they switched to the sitting position. I'm a bit dissatisfied that Yuta finishes relatively quickly, but I suppose that's just right for the actresses. Combining the smiling with the sex adds a sense of realism, making it a great directorial choice.
*The sperm dripping out at the end is so real! This is a work that makes you want to try something with a senior like this, even if it's just a kiss.
*A work by Airi Kijima's junior. If I had such a beautiful senior, I would have no choice but to keep my cock standing and fuck her instead of doing work. However, Airi's blowjob and cowgirl style are outstanding. The last creampie is also perfect. Even though she is such a beautiful person, for some reason Airi doesn't make her pussy shaved and keeps her bristly hair.The semen dripping from her vagina is so cool!
She's a veteran actress, but she still maintains such a beautiful body line. The small chest is actually a plus in its own way.
