Between Tania's legs

Since your arm was already around Tania, you just moved your hand between her legs and grabbed her dick. Tania gasped and flinched slightly in the water, but before she could tell you anything, you cupped her cheek with your other hand and kissed her.

Tania's eyes widened and she looked around flustered that anyone would see you two and most of all scared that Sophie would notice. Fortunately for her, nobody has noticed yet, and since your arm was around her waist it looked more like you two were glued to each other than you were jerking her off.

You pull off the kiss and put your finger in front of your lips in a «shh» sign before giving Tania a subtile blink that made her immediatly blush bright red. You placed your towel over your head so that nobody would find you suspicious when you looked down into the water. Tania just looked at you.

You started rubbing her shaft. Everything underwater was different from usual so you had to change your way. You pull on her dick then let go. Peel the base down to stimulate the gland, then flick the urethra making Tania twitch. She was already pretty sensitive and dizzy from the time spent in the hot bath and the beating her balls received earlier, so the heat building up inside her body combined to the bath's temperature didn't help at all. Tania's gaze slowly got unfocused as her mind drifted.

You slowly felt her legs opening more allowing you to move better. You did not hesitate and got lower and lower. This space allowed you to stimulate a larger amount of her cock and you could feel it throbbing now. But the position was uncomfortable so you turned to Tania and pressed yourself against her arm.

Just when Tania started to relax, you noticed Sophie watching you from the corner of her eyes with her towel slightly lifted. You freeze for a short moment. Tania looks at you because of the sudden pause, so you throw your head toward Sophie for Tania to look and she did, only to make eye contact with Sophie.

"Can you two tell me why the hell are you squirming like that ?"
Sophie asks with a sigh. You point down into the water with your index and Sophie obviously straighten up to look down. The view was a bit distorted because of the depth but after staring for a moment she finaly understood what was happening and gasped.

Tania immediatly blocked Sophie's mouth and shook her head in fear but Sophie used her elbow to hit Tania in the bladder making her gasp and double over in the water.

"What's wrong Sophie ? Are you feeling embarassed ?"
You help Tania out of the hot bath and her head slowly rest back on the border of the gigantic sauna.

"Are you asking me ? Seriously !?"
Just like for Tania, you use your finger and shush her. Sophie stops and look at you with a mix of annoyance, desappointement and disgust since she was next to Tania.

"I told you we'd make Tania feel good. And I was not lying."
You grab her hand move it down between the tired Tania's legs.

"If you could help me I'd really appreciate it"
You tell Sophie who was flustered and was barely touching Tania. She looked back at you and could feel your hand going up and down underwater, while Tania was stunned from her previous blow.
