Affair With A Lifeguard

I have been married for 5 years which makes this feel even worse. All summer I’ve been having an affair with this freshly 18 lifeguard at the pool I run. She’s got such a perfect and amazing body. Not very busty but not flat or too petite, a smile and eyes that can make you melt, and sex skills no one her age should have. Every time she works a night shift, we hook up in the office. She’s on birth control so we recklessly fuck and go crazy. She has the sweetest and most addicting pussy. I’ve lost count how many times we have hooked up, probably in the 20s by now. I know I shouldn’t but she’s just insatiable and she knows it
