Man, what a fun chapter! I was beaming most of the time reading this. This the perfect blend of both serious and humorous moments. Moka and Tsubomi's chemistry this chapter felt great. Lots of cute scene with them at the sex store. I may be a Kanako-ist but this chapter is another reason why Tsubomi is the fan favorite in this series, heh heh.
While it was a fine idea for Ueno to lose his virginity to Moka, a part of me do wish Ueno and Tsubomi lost their virginity together during one of the last practices together. That would easily be one of the best chapters in this series but that won't happened unless the mangaka makes a 'what-if' chapter, lol. Now that Ueno graduated, Tsubomi is the only virgin left from the main cast, and she lost the only person she can trust to have sex with. It would be incredible if Tsubomi somehow convinced Moka and Ueno to have sex with him as a one-time moment just to see how it will be like but good luck on that front. Hopefully, Tsubomi either finds a boyfriend from the tennis group and/or she realize that she doesn't need to catch-up with her friends in sexual experience ( or being a virgin is no big deal, and you shouldn't rush to lose it.)
We'll see next chapter as it can't come soon enough...well translated, that is!
