Somehow Antonin's commentary made the whole experience much more exciting. She knew there was truth in his statement. Why else would Augustus stare up in the very direction that he knew she was in? It wasn't a coincidence. Antonin increased his pressure, ripping a leg-trembling orgasm out of his distracted wife. Silencing spells or no, she bit her bottom lip to keep from crying out. What they were doing all felt very, very wrong. Surely they should give the other couple their privacy. Pretend like they weren't aware of what was happening downstairs and go to bed. To sleep, nothing more. At the same moment that Augustus was pulling Alecto up off her knees to encourage her to climb onto his lap, Antonin pushed Hermione's clothes down over her hips until they fell to her ankles.
