@setokaiba From the description the first volume of this anthology might be what you're after. I have bought it, but haven't read it yet. The second volume has high school girls on the front and the third volume looks like it goes into the bedroom, so might not be what you're looking for. I know you said you don't do digital, but still useful to have a look at the preview pages:
