I'm only guessing from the context of the parent post... that maybe they were doing something similar to truth or dare? It looks like Miku got a "fortune" that specifically said to have sex with an old man which leads me to believe some one gave it to her. Given the reaction of the boys I'd almost think maybe they didn't think she'd go through with it?
That said I think Kaito is enjoying it, too, he's just trying to not show it as much. And Gakupo just seems upset, possibly because he lost a bet or something?
Maybe they're just watching staged porn. The plot is typical(a hot girl is not only allowing a bunch of ugly dudes to bang her but also appears to be "pleading" for it).
LOL Gakupo is jealous Kaito is drooling and Len is Fapping XD
Even so, that you'd be fine with doing it without a condom...
I might carelessly cum inside you, you know?Really, girls nowadays are amazing.
Well then, I'll cum inside you, Miku-chan, without holding back.There, I'm cumming!!Having a man pump his semen into my pussy became a habit for me too.P-ple♥ase!♥RelayAh! ♥Haaah! ♥Big sis Miku, big sis Miku...*fidget*Funh!Fuuh!*bluuush*Uuhm, young lady?
This is the men's bath.Y-yes...
That's right, but I wanted to talk to you guys...If that's how it is, I guess it's fine...When I saw the penises of you guys, it became a bit painful...Uhm... Actually, I just recently broke up with my boyfriend, and...If it's okay with you, would you mind having sex with me like a lover?As expected, the tightness of a young girl's pussy is something else. It's like it's clinging to me.(Lie)It's okay! ♥♥
Cause my ex-boyfriend loved cumming inside me when having sex.*fidget**twitch♥*
