John, with a mischievous glint in his eye, offers to apply sunscreen on his stepbrother's wife, Bella. He starts innocently enough, but as he reaches her back, his hands stray, cupping her full breasts. Bella gasps, shocked but aroused, as John's thumbs graze her hardening nipples through her bikini top. He leans in, whispering, "You're burning up, Bella." She blushes, pushing his hands away, but not before he gives her sensitive flesh a gentle squeeze. John grins, knowing he's crossed a line but eager for more.
