While Bill didn't mind putting on a bit of a show in public he still had the presence of mind to not start shagging a girl in the middle of a pub. As Lavender turned her head to kiss him, Bill claimed her mouth hungrily. "We're not doing this here," he said against her mouth and pulled back suddenly. He'd take them both someplace private if they wanted, though Bill didn't know how willing Parvati would be. He certainly knew Lavender wanted him.
Rubbing his palm against Parvati, Bill leaned in and brushed a kiss against her lips. "Lavender and I are going someplace more private. You're welcome to join us, love."
