Bathroom tease turns into slow swimsuit grind from behind

She slipped into the bathroom after trying on her new black one-piece swimsuit, the cutouts framing her full breasts teasingly as she admired herself in the mirror. Her blonde ponytail bounced with the blue scrunchie, thighhighs hugging her legs, building that slow heat just for him. He watched from the door, naked and hard, unable to resist any longer after her playful glances all day. Now, bent over the vanity, she feels his hands grip her hips firmly, his cock pressing slowly against her wetness through the fabric before pushing in from behind. Her body arches in anticipation, breasts spilling out and swaying with each deliberate thrust, a soft whimper escaping her lips as the build-up finally ignites, her walls clenching around him in teasing rhythm.
