The anticipation alone was killing me!My sister first removed her shirt, slowly pulling up and over her head, leaving her beautifully flat stomach and...bra-covered tits behind. She flipped her hair back and threw the shirt on the floor. Then one by one she took off her socks and shoes and kicked them aside. What she did next almost made me cum right there watching her. She turned around so her back was facing me, then she very slowly wiggled out of her jeans, carefully sliding them down her. I slid my hand down her stomach. I untied her bikini bottoms while she grabbed my engorged cock and pulled my briefs off. I slid my fingers between her labia. Both of us started to breath faster. She grabbed my penis and pulled me into the shallow end of the pool. She sat me on the steps of the pool. My cock was rock hard. Her hands gently caressed my balls as she softly thrusted my shaft underwater. I was in nirvana!! I pulled Kelsey’s body against mine and I bit her neck. I whispered in. "I'm serious, come on!" You can't borrow a quarter, Kelly!" Mark grinned. "You have to play with your own money." But I don't have any more. Please?" I looked around, batting my eyes and making a puppy dog face, but it was no use."Nope. You're out of money, you're out of the game, that's how it works," Cal said."Well ... Maybe..." Tony started saying and I smiled at him. "You got anything worth a quarter? You know, something to throw in?" Ummm..." I thought about it. "I have my earrings," I. They were so erect that they looked like they might squirt milk at any second, but she hadn't been pregnant for ten years. Her breasts had that quality that some mature women manage to maintain, where they had never really grown big enough to get saggy. They pretty much supported themselves, and I knew they wouldn't have looked a lot different when she was twenty. There were tan lines, as her house had a pool and she kept fit, so there were these milky white triangles separated from her olive.
