Help Lexi only to make Sarah jealous

I grabbed two bottles of sunscreen and handed one to Sarah, telling her to do it on her own. Sarah gave me a look, but I didn't care. I wanted to make her jealous. I smirked as I saw Sarah's face fall when I chose to put sunscreen on Lexi instead of her. I could tell that she was a bit jealous. I wanted to play with her a little bit and make her realize that she wasn't the only one that could grab my attention.

I took the bottle of sunscreen and poured some on my palm. I started applying it on Lexi's back, starting from her shoulders and working my way down to her lower back. I could feel her soft skin under my fingers, and it felt really nice. Lexi let out a soft moan as I massaged her back, and I could tell that she was enjoying it. "Ooh, that feels good," Lexi said with a sigh. I chuckled. "Glad you like it." I continued to rub the sunscreen onto Lexi's back, making sure to get every inch of skin covered. As I moved down to her buttocks, I could feel her tense up a bit. I looked up at her and saw that she was blushing a little bit. "Relax, Lexi," I said with a smile. "I'm just making sure you're protected from the sun." Lexi nodded, and I continued to apply sunscreen to her legs. As I worked my way up to her thighs, I could see her biting her lip. I couldn't help but feel a little turned on by her reaction. I wondered if she had any idea of how much I wanted her. As I continued, I could see Sarah looking over, her eyes filled with jealousy. I smirked to myself, feeling a sense of satisfaction at making her jealous.
