As you bounce along with Stacy, she eventually makes it to your destination. She stops at the lane Brittany was swimming in, and drops the towel on the ground, before pulling you out of her bikini and kneeling down to set you on top of the towel. "Alright stud, I've gotta be on my way. It was lovely to meet you, and I hope we meet again!" You smile up at her, thank her for her help. Before turning to walk away, Stacy stands up and yells to Brittany, who has just started to slowly swim back to your side of the pool, "Excuse me miss! We brought you a towel, here!" Stacy points at you and the towel, and then begins to walk away, giving you one last smile and a little wave as she does.
You sit on the edge of the large white towel, waiting for Britanny to arrive. You hope that she'll be as nice as Stacy, or at least nicer than Kim, but you don't have high hopes; she is a friend of Kim's, after all. Brittany arrives at the tiled side of the pool, and uses one hand to grab the ledge. As you begin to outstretch your hand and introduce yourself, she looks towards Stacy, and mumbles "That was nice of her" while she uses her other hand to grab the towel. As the folded towel is jerked forward, you fall backwards and land on your back, dizzied. Brittany, still looking at Stacy, lifts herself out of the pool, displaying her gargantuan, soaking wet breasts, covered in a widely cupped, but thin and almost transparent white bikini. As you tried to scramble to your feet, Brittany fell forward, pressing you into the towel with the flesh just above her right bikini cup. You couldn't move, but the towel was forgiving enough that even Brittany's immense breasts weren't quite crushing you. As Brittany used the edges of the towel to dry the sides of her breast and her arms, her legs still dangling in the water, she spotted Kim laying in the grass. She smiled and said playfully to herself, "Lazy girl, sleeping on the job HEY KIM!" As she reached up and waved enthusiastically to Kim, her whole body shook, jiggling her warm and damp flesh against your entire body. Kim waved back, and Brittany said "I'll just be one second!"
Then Brittany lifted herself off the towel, and...
Option A: You are stuck to her breasts when she goes to talk to Kim
Option B/C: She sits on the towel before going to see Kim, or she spots you as she gets out of the pool
