I had just finished 3 laps of the pool and was relaxing in a chaise lounge when I heard my aunt’s voice, coming from her balcony.

“How’s the water, baby?”

“The water’s great. You should come down and take a dip.”

I don’t think she realized I could see into her room on the second floor, because she turned from the window and began to remove her clothes. I watched from behind my sunglasses as aunt Karen pulled her tank top up over her head. She wasn’t wearing a bra and her breasts were fully exposed to me. For a woman 15 years my senior they looked fantastic! Each one was full and high, not sagging, her nipples were surrounded by dark pink circles. Aunt Karen let her hands slide down each breast as her hands went to her waist to undo the button on her jeans. Behind my sunglasses my eyes were wide with delight, I was seeing quite a show! My cock was responding also, getting hard at the sight of the beautiful woman in front of me. Aunt Karen undid the button and pushed the jeans down her hips, doing a little ass wiggle as she went. She wore no panties, and I almost came just seeing her ass. She stood in front of her mirror for a few moments and let her hands run up and down the length of her body, squeezing her tits and rubbing her pussy before she went to the dresser for her swimsuit. Another surprise! Aunt Karen’s swimsuit was a bright yellow thong, the top just two small pieces of material, just barely enough to cover her tits. I watched as she put it on, and reached down to adjust my very uncomfortable erection.

Moments later Aunt Karen stepped out the door and moved to the diving board.

My eyes followed her as she tested the board by bouncing up and down, her tits moving sexily. Closer now I could see that the patch of material that made up the bottom of the suit was just a tiny triangle that covered her cunt lips.

Aunt Karen dove into the water and swam towards the end I was sitting at.

When she stepped from the pool her suit bottom clung to her cunt lips and the small patch of hair covering it, I could clearly make out the folds of her pussy.

Her swimsuit top meanwhile had fallen below her tits, the force of the water must have done that. She didn’t seem to notice, and headed my way. I tried to pretend that my eyes were closed behind my glasses but I think my stiff cock gave me away.

Aunt Karen sat on the edge of the chaise lounge with her back to me and asked “would you put some oil on my back baby?, I don’t want to burn” I sat up rather uncomfortably and reached to pick up the suntan lotion. While I did that Aunt Karen reached behind her back, undid the bra straps of her suit and removed the top “you don’t mind do you, Chris?” I stammered an answer and put some lotion in my hand, and began to rub it on her shoulders. Her skin was soft and warm to my touch. I let my hands move from her shoulders to her back and then started downward. I could see the sides of her tits and wanted to reach around and grab each one. Aunt Karen must have read my mind, she took hold of my wrists and pulled my hands around her body, putting one on each hot breast. I felt the nipples growing in my palms and began to rub lotion on them, they felt heavy to me and I gently squeezed each one, letting the nipples slip through my fingers. Aunt Karen moaned quietly but didn’t try to stop me. She took one of my hands and moved it to her abdomen. My fingers now were close enough to reach beneath her suit bottom and touch her private parts. I didn’t wait for an invitation. I let my left hand slide beneath the silky fabric and felt the tiny curly pubic hairs that covered her pussy. Aunt Karen leaned back against me and opened her legs slightly. My fingers found the already full lips of her cunt, she was moist and I let one finger slip easily into her twat. Her thighs clamped closed on my hand and she began to move her hips slowly in time with my hand movements. My finger was buried deep in her and I could feel her hard button of a clitoris rubbing against the heel of my hand. My other hand continued to massage her tits while her breaths came in short little bursts.
