Would love to see a translated version of this, I was able to figure out the gist of some of the word bubbles but my translating skills are nowhere near good enough to tackle the whole. The story is pretty straightforward; the guy hears a rumor that this tomboyish schoolgirl does joshikousei (i.e. prostitution) so he invites her to a love hotel. This is her first time doing it with a stranger for money and she acts a little embarrassed as she strips and gives him head. After the guy moves the tomboy to the bed and pulls her panties aside, she asks why he isn't putting a condom on, but the guy promises her he'll pull out before he cums. A few panels of missionary-style sex later, he says he's going to cum inside her anyway, and does despite her objections, and the tomboy worries she'll get pregnant. (Much of the other dialogue is typical "girl getting fucked" sounds). Then, the schoolgirl remembers the course her client ordered also included banging her in her swim-club uniform, and is especially embarrassed/turned on by having sex while wearing it. At the end, she muses that not only did she end up getting banged in her club swimsuit, but the guy also came inside her again.
