The morning was hot.
Just before lunch, you come out, and I find myself staring in admiration. In a marvelously revealing black and red two-piece suit, you are quite an eyeful. Your stomach is firm and flat, your breasts quiet curves. When you begin to put on your sunblock, I politely asked if you wanted any help. You accept my offer with a smile, and stretch out, face down on your stomach on one of the padded lounge chairs. I rub the cream into your shoulders and your arms, and the tanned muscles of your back.
Its only natural to suggest that you allow me to undo the strap holding your top on, since it was obstructing my covering your back with the sunblock. You are silent for a moment, and when you say "Why, sure!", there is a laugh in your voice.
Your bare back is smooth and firm and feels quite erotic under my hands. The bottom of your suit is tied in a knot at one hip; when I suggest removing that also, you are silent for a little longer, and your voice even more amused when you agree, and raised up your hips to help.
I start rubbing the lotion into your naked buttocks, running my hands greedily over the backs of your thighs and knees. I could feel myself beginning to swell, and I told myself it was time to get under control.
When I am done with your back, I start to re-tie your bathing suit. However, before I can do so, you turned over. Your stretched out naked on the lounge, reaching your hands up over your head. You are long and slim and tan, and my cock was not at all worried about our ages.
"Now the front," you say calmly, and closed your eyes and smile.
I swallowed hard, and apply the cream to your shoulders and your upper chest. Your breasts move slightly as I rubbed around them, long dark nipples gradually coming erect. I do your stomach and hips, and you roll your legs slightly apart so I can get at your inner thighs. As I worked my way down to your knees and calves, I noticed that the soft hair between your legs is starting to get matted and moist. Mixed with the smell of the lotion was just a hint of the scent of woman.
I decide I've missed some rather important spots, and put more cream on my palms, I take your breasts in my hands, gently working in the lotion, rubbing the tan skin, and running my fingers over your long nipples. You squirm slightly on the lounge, your face relaxed and happy.
Your eyes open. "That was very nice; thanks!". I take a deep breath, persuade my hands to leave your body, and stand up. "Now take off your trunks," you continued.
When my eyes widened, you sit up and laughed, "Turnabout is fair play!"
I turn away from you, slip off my trunks, and lay face down on the other lounge, hoping my cock would calm down before it was time to turn over. That was a vain hope, though. You gingerly straddle me energetically, your thighs warmly rubbing my sides, as your hands applied the cool cream. Now and then as you do my back, I can feel the hairs between your legs tickling the backs of my knees.
