Now that Andrew had rolled over onto his back, Rachael took the opportunity to straddle the top of his legs, the smooth nylon of her bikini bottom brushing against his skin.  She reached for the sun screen, squirting more into her hand and leaning forward to start at his shoulders then work her way down.  Her soft hands began to rub the lotion into his chiseled shoulders, and as she leaned in closer to him, Rachael’s bare breasts rubbed lightly against his naked chest.  Her breath caught in her throat and she was certain that Andrew could feel how hot and damp her bikini bottom had become.
