Lydia lays on her back under an umbrella, a book laying open at her side. She has fallen asleep in the middle of reading, enjoying a nice relaxing day at the beach. Suddenly, something smacks into her chest, and instinctively, her arm swings up and slaps it.
As you land square between Lydia's breasts, you bounce a little. You're just glad you've survived the fall, but it doesn't last long as her hand overshadows you and swats you into her breast. This wakes Lydia up, and she jerks a little, shaking you. She then looks around, shakes her head and sits up.
She figures she just shivered a little in the shade, and so she'll move into the sun. Just need a heavy coat of sun screen to keep her skin as pale as she liked it. Pulling a bottle of sunscreen out of the bag sitting next to her, she squeezed a ton onto her hand, rubbed her hands together and rubbing herself down, starting with a thick coat on her breasts, then working down her arms, then her stomach and back. She squeezes out a bit more before rolling over and getting her butt, her hips and her legs. Then she stands, pulls her towel into the sun and lays down on her front, looking around. She spies a couple attractive older women sitting not too far away and growls, then lays her head down on her arms, eyeing them every now and again.
As Lydia sits up, her breasts come together, holding you in place, and as she prepares the sun screen, her arms press them together further, crushing you between them. Then her hand comes rolling over her breast, and you are coated in the sticky, white stuff, trapped, face-first against her flesh. Her hands move away, but you find you can't pull yourself free, or even move to alert her to your presence. As she rolls over, you find yourself hanging freely, gravity not even able to pull you away from her. You gulp. This might be a long day.
When Lydia moves into the sun and lays on her towel, you brush up against it, and as she lays her head down, you are squished between her soft skin and the towel-covered sand below you. If you can't get noticed soon, you'll be trapped here for a while.
