Good Boy - Theta Alpha Gamma, #4

Brad "Frat Boy" Feller and Sebastian "Toppy" DeWitt have been together for nine months, and their relationship is as hot as ever. The only cloud Brad sees on their horizon is Sebastian's stress over his thesis. And their uncertain future together after graduation. And how Sebastian sometimes takes Brad for granted. And Sebastian's unwillingness to introduce Brad to his father. Other than that, everything's awesome.
All of Sebastian's energy is currently devoted to his thesis, and getting into a top-notch PhD program. Fortunately, his boyfriend takes care of all the domestic stuff and Sebastian's needs. Any minor strain between them will disappear and they'll return to the status quo after Sebastian graduates. As long as nothing upsets their delicate balance in the meantime. Then a friend Brad once had a small fling with is forced to take refuge with them, and Frat Boy and Toppy's delicate balance topples like an elephant on a waterski.
Now Sebastian has to face some truths about how he's been treating Brad, what he wants for their future, and what he has to do to get it.
