I've yet to read the first and the third but I went to the 2nd since it was a one shot and quick to get though. You may have misunderstood, I specifically wrote that I want the seme to be fantasising, but the 2nd one had the uke fantasising about being groped. I sure hope the other two recommendations have the seme fantasising.
Please recommend manga like Uminari ( http://www.mangago.zone/read-manga/uminari/) where the seme has vivid fantasies or wet dreams or day dreams about making love to the uke?
