ARM-603 - AJOI: T-back panty provocation, first-person ejaculation instruction

I'm so glad there's very little 'T-back teasing,' and since all the actresses have such great backsides, this is a must-watch for anyone who loves T-back thongs. Seeing the anus through the thin string thong is also a huge plus. If I had to nitpick, there's almost no decoration on the front or back, so it looks a bit like a swimsuit. I'd prefer something with a little ribbon or lace, but it's a shame that those usually cost more. Still, even if it were a bit pricier, I'd buy it for this quality.
