His grip had gone from the side of the tub when she pressed against him, leaving Tony balanced precariously to catch her and hold her fast under her arm with an appreciative hum despite the dampness seeping through the front of his shirt. He didn't really expect her to pull.
Water sloshed and poured over the edge of the jacuzzi to flood across the bathroom floor, reaching as far as the counter and pooling as it continued to slowly leak out even after the splash had settled and Tony's surprised giggle died down. He had to twist, kicking the leg that still hung over the edge until he was soaked from chin to toes and still snickering when he knelt over Wanda to kiss her like he didn't much mind that his shirt was clinging to his skin, turning perfect, crisp, white Egyptian cotton transparent and warping the weave with every shrug. Pepper would remember where he bought it. Now, he had to pull himself away from Wanda for an agonizing too long to be a slightly more successful with the buttons and still drag the shirt off over his head, making his hair stick on end and leaving the bathroom echoing with the heavy slap when it hit the tiles. That, Tony didn't really hear. He was gripping Wanda's hips pressing against her again for an impassioned kiss like he meant to make up for precious seconds lost.
