Nope!

What starts out as stunned silence, gives way to just pleasured tranquility as Maria slowly strokes your cock. The two of you kiss for a little longer, giving you the opportunity to put your arm around her side and run your hand down her back. After a little bit, Maria pushes up onto one hand and looks around the lake, presumably to see if there's anyone around. Apparently satisfied, she maneuvers up onto her knees.

"Now, you just stay right there, no need to do anything. I just want to show a little gratitude for helping me out today," says Maria.

When you start to rise up, Maria puts her hand on your chest and pushes you back down, then slides down your body, kissing her way down your chest, then stomach, then you feel her lips on the end of your dick. Her tongue starts to trace the underside of your shaft, down to your meaty balls and then back up, before she officially envelopes your cock with her mouth.

Since she's on her side lying opposite you, her legs stretch out by your arm. As she slowly bobs up and down on your dick, taking a little more each time, you start to run your hand up her leg. Her legs are lithe and toned. With your fingers, you can trace out the graceful muscles that run up her calf, the tendons behind her knees, and then all the way up the back of her leg until you arrive at her butt, where you settle your hand with a squeeze.

You feel, more than hear her slight moan as you squeeze her ass, and it clearly compels her to pick up the pace. Maria may not have had sex in months, but for you it had been a bit longer than that. So, it didn't take long of her mouth working its magic for you to start to feel the urgency in your balls. It was only years of experience that had kept you from blowing your load in seconds.

Partially to encourage her, and partially for fun, you slide your hand over her butt and search with your fingers for her lips. You find them, warm, wet and inviting, and run a finger all around before putting a finger in a little. Maria responds enthusiastically, redoubling her efforts on your dick, and by the the feel of it, impressively taking almost half of it in. Before you know it, you can't take any more.

"Ohfuck, Maria... I'm cumming..." you groan.

You assume Maria heard you, because you feel her free hand reach and cup your balls, which is all you can take. You start cumming, and Maria, sensing it, stops bobbing her hear and just hold her mouth over your cock, slowly pulling away. When you finally finish cumming in your new friend's mouth, she pulls herself upright onto her knees again.

"MMM... god, that was fun, huh?! Going down on a guy your age feels great. It feels like I contributed to a good cause, or did a charitable work," Maria says, laughing.

"Oh, hardy-har-har... make fun of the old guy," you reply, propping yourself up on your elbows.

"Well, I think I earned a joke, don't you," she says with a wink.

"You sure fucking did... holy god. Thank you, by the way," you say, trying to sound grateful without sounding ridiculous.

You both stand yourselves up and start walking back towards the cottage.
