That cover pic immediately caught my attention. What a hot pose is that! Rest of the artwork is uncolored, of course, but still very enjoyable. There is an x-ray view on p. 11, too. Thanks for sharing this!
Man, one thing I love about Rin x Archer doujins that it's always almost constant that there's foreplay on Archer's part, and he doesn't just JAM IT IN. It's sweet, tsundere vanilla and sometimes I really like that.
