A one piece

When you turn around, you see your friend beginning to remove her t-shirt. Once it came off, you're marveled by the sight of her toned back. You could almost feel your jaw dropping to the ground. Though you lowkey wanted to see her in a more revealing swimsuit, you'd look a gift horse in the mouth and let the blue one-piece arouse you more.

By the time she removed her short shorts, you get a breathtaking sight of her entire physique in that bathing suit. It's a Speedo Pro Back One-piece swimsuit. Very fitting for an athletic woman such as herself. You watch her place the removed clothes onto her towel, still smitten by the sight. Part of you had a small enticement for women in swimwear, but factor in that it was one of your best friends...

As you get a nice look at her back and firm butt, you never noticed Christina sparing a subtle glance behind her. No doubt, she knows you're checking her out... and she likes it. She's feeling satisfied that you're getting turned on. In an attempt to tease you, she bends over a little to reach for her goggles. There's a faint blush on her cheeks.

In the meantime, you do your best to avert your eyes from her figure. Next step is to remove your shirt and apply sunscreen onto your chest area. Though now that you think about it, you could use her help in applying the white substance onto your back.
