Vary things up

"Wow, that was so hot," Lethine says as you pull out of her friend. "It really turned me on!"

"Care for a go then?" you ask, grabbing her. You push her against Nemiri, her back to the other girl. When you open up her legs and enter her, she's in the same position that Nemiri was just a second ago, but sandwiched between the two of you. Her hair comes loose of its plait on your first thrust and tumbles loose over Nemiri.

"Ohh, fuck!" Lethine moans loudly. She's too tight for you to go as fast as you were just a moment ago, but you make a good go of it. Her skin is flushed, sheened with sweat and steam from the hot water. "Fuck... Oh, fuck me!"

Nemiri kisses her friend's neck from behind and wraps her legs around her. "Oh, you're so beautiful," the brunette whispers. Her hands snake around, sliding across smooth skin and cupping Lethine's ample breasts, which lie just above the surface of the water. "He's big, I know, but it's good isn't it? It's so good..."

"Oh... Ohh yes, it's so good," Lethine whimpers in answer. "Ohh, gods..." Nemiri's legs suddenly wrap around both your waist and Lethine's, so that the three of you are firmly locked together.

You crush your lips against Lethine's, dance your tongue into her mouth and duel with hers. Then you tear away, move your mouth to Nemiri's, which is still tasting the side of Lethine's neck. You kiss the brunette too, both of you moaning erotically next to the ear of the girl trapped between you. Lethine will not be left out though. She turns her head, eager to join in. You share a sloppy three way kiss with the two girls.

"Mmm, I'm going to come," Lethine whimpers, suddenly drawing away. Her eyes are closed, her lips parted to draw in ragged breaths. "Oh fuck, I'm going to come!"

Nemiri murmurs comforting words into her ear, her tongue flickering out now and then to play against the tip. You pick up the pace as much as you can. Then Lethine is crying out with joy, her pussy clenching around you. Her body shakes, and water splashes up and around as you and Nemiri hold her.

You're not far off yourself now. "Ah, fuck!" you groan, leaning back. Lethine, coming off her own orgasm, immediately takes the opportunity. She throws her arms around your neck and rides your cock hard, no longer supported against Nemiri.

"Come inside me, Sir John!" she says. "I want your cum!"

Nemiri gets up, swims round behind you, presses her body against your back. Her hands play over your skin, on tweaking a nipple, the other sliding down between you and Lethine and finding your balls underwater. With the extra stimulation, you can't hold off any longer and blow your load.

Your cum shoots into Lethine as you let out a strangled shout. Your whole body and mind are overcome with intense pleasure, unable to cope with what's happening to them. Lethine keeps riding until you're completely done. Then, with one last kiss, she climbs off you and swims off into the deep part of the pool with a joyful laugh.
