You wouldn't believe what excites all the guys” my stepmom said. She smiled. Peter studied it. Britney tossed a restless strand of hair behind her ear. She shrugged and scratched her heel. For a moment the whiteness of her panties flashed under her skirt. She enjoyed the way Peter tried not to look at her. “Actually, you might know something about it,” she added after a moment. “What?” Peter asked. Britney looked into his eyes. She saw his unease, but also his curiosity. And she saw something that her younger horny brother hadn't noticed. Starting bulge on trousers. “I couldn't sleep last night,” she said, and at that moment Peter's heart almost stopped. Britney decided to go straight to the point and no longer torture him. She stretched out her long, tanned leg. She put her foot on her brother's knee. She felt him twitch and his hand instinctively gripped her instep. “Shall I put her away?” She asked with a smile. “No, you don't,” Peter stammered. “most of the guys were excited by female legs,” Britney said, pushing her leg a little higher.
