Seeing D run off, Will narrowed his non-existent eyes, musing, 'Sneaky little thing...' while secretly feeling impressed. D had clearly sensed that something was amiss, lending credibility to her standing as the greatest assassin from Zoathaar.
Since there wasn't much else for him to do with D gone, Will decided to return to his body, where he was greeted by a sharp, pulsating pain in his dick.
'Shit...talk about a tremendous fucking oversight...' Will groaned internally, having failed to account for the fact that his penis was still nestled within Una's pussy when he separated from his body. As a result, he came back to his dick feeling like it was about to pop as her entrance had prevented his blood from flowing back into his body. That, combined with the rest of his body going limp, nearly led to the worst outcome.
