Glad to hear you enjoyed yourself, Cupid. I forgot to report on my experience at 24 Kaikan in Shinjuku.
It was MUCH more friendly to foreigners than I ever saw when I lived in Fukuoka. I got fucked 3x in about 4 hours...all 3 guys in shape, in their 20s and 30s. I never made it to the shower areas, with gloryholes between the showers! I just found those after I'd cum twice and was there to actually take a shower!
I was there on a Saturday from about 5pm to 9pm, and enjoyed myself a bunch. I'd go back there next time.
