Go for a swim with her

The smell is too strong for you, but you're not about to deny your new traveling companion her satisfaction. You plant a last kiss on her inner thigh and lift your head. She's smiling at you.

"Want to go for a swim?" you ask, your face only inches from hers.

"Oh, a water maiden? I like it."

Harietta leans in and plants her fat lips on yours. You open yourself to her kiss, her thick tongue filling your mouth. Before either of you can get too worked up you push her gently back and get to your feet.

"I guess we'd better take these off," you say.

You untie your blouse strikes and loosen it until you can slip it over your head. You can see Harietta in the moonlight, admiring your naked body as she undresses as well. She is heavyset, with wide hips and a very plump ass, but other than a little cellulite on her thighs she holds it quite well. Her belly isn't too big and her enormous breasts draw your eye. She has huge brownish-pink areolas and thick nipples. The breasts droop some, but not quite as much as you'd expect given their size.

The stream is ice cold and your nipples stiffen sympathetically as your toes sink into the frigid water. The air is warm though and you're hot and sweaty from the trail, so it feels nice to slowly slide your luscious body into the chilly water. You giggle and hiss and whisper to one another to keep from waking up her husband. Your bodies adjust to the temperature and you float together in a portion of the stream that is up to your breasts.

You talk a little more, but it's clear she's quite aroused and in minutes you are pressed up against the rocks by the bigger woman, her lips smothering yours and her tongue filling your mouth. She dips her head beneath the water and you feel the warmth of her mouth around your nipples, sucking and licking at them and teasing them with her teeth. Her hand slides down your stomach and her pudgy fingers find your slit. You gasp as she plunges them into your depths and you rock your hips. She stands up again, hair black hair dripping wet, and smiles. She leans in close, breath hot against your lips, fingers fucking in and out of your slit.

"Cum for me, hun," she says. "I can feel it."

She's good with her fingers and it doesn't take long. You explode in orgasm, wanting so badly to scream with pleasure that you press your lips to hers just to stifle your cry of climax. Your quivering orgasm leaves your thighs shaking. The stifling kiss becomes more making out, but now you are the aggressor, tasting her mouth with your tongue and enjoying her soft body with your hands. Your fingers roam to her cunt, massaging and teasing and working water into her hot hole. You tease her big, soft ass and her warm crack and wash there as well, letting the stream do the work of preparing the way.

"Please," Harietta moans, breaking the kiss only momentarily.

Pleasing her was always your intent, but now you need to decide how exactly you intend to go about it.
