Suggest some lotion

My cock starts to stir in my pants as I gaze at her naked back. She looks great lying there sprawled out in the sun, and I'm dying to see if she has been avoiding tan lines on the front as well.

"You really should wear some sunscreen," I call out to her.

She turns her head and looks up at me, her big white sunglasses hiding her eyes. But her mouth opens with surprise at the sight of a black stud watching her sunbathe. Smiling mischievously, she replies, "I know, but it's too hard to reach my back, so I don't bother. And I don't have any lotion with me..."

"That's okay, baby," I say with a grin. "I can rub it all over your back... and everywhere else."

"You would really help me like that? You're so sweet..."

If I can get my hands on some sunscreen, this sexy brunette is definitely going to let me run my fingers all over her body. And if she's the kind of girl who lets a guy like me feel her up outside, she'll do anything!

But where am I going to get sunscreen?
