This scene really needs no explanation. Words are trivial when the meat is this substantial. Tommy got the rep for BMOC when a bunch of friends went skinny dipping in high school. After that, every girl in school wanted what Tommy has. You saw him just a few weeks ago going solo. Now, Brendon deep throats that massive prick for the first time ever! It takes several attempts to find the right angle, but when he does, Brendon likens it to a delicious form of torture; sore throat, can't breathe, watery eyes... sounds like love.
