Take her from behind

You swiftly snap off Autumn's bikini bottoms, and toss them to Sophie. Before she can react, your wet, hard cock is thrust inside of her tight ass. Autumn continues to eat out Rachel as you pound her ass from behind. As you are about to cum, you grab her waist and pull her away from Rachel, shooting your sperm deep inside her. You slide your cock out, and Autumn falls on the sand, cum leaking out of her.

"Oh, ooh, oooooh!" Autumn moans as she turns over, revealing a completely smooth-shaven pussy. "You fucked me so good, John!" There is at least a dozen people watching everything unfold, the men in the group absentmindedly stroking their cocks (none of which compare to yours, of course).

Eventually, the excitement dies down and it's just you and the girls left at your spot.

"Hey, I've got a naughty idea," Sophie says, winking at you.

"What's that?" You inquire. The other girls look at Sophie in anticipation.

"What if we brought someone over to the nude beach?" Sophie offered. "We could go over to the other side, find someone who's wearing a bikini, and then bring them over here for some fun?"
