Yes

The curiousity got to Sophie and she sighs. "Ugh... Why are you so.. Touchy and horny all the time... You better cum quickly" Sophie tell Tania before grabbing her balls. Tania's body twitches slightly under Sophie's touch, and she was surprised herself.

You smile at how intrigued Sophie was but you were not gonna lose to your little sister on your own battlefield. You started rubbing Tania's dick roughly and kissed her warm neck. Like struck by a thunder Tania suddenly came back to life with a gasp and bit her lips.

Sophie's eyes widened from the surprise and frozen. But the feeling of the warm balls in her hands made her want to explore Tania's reactions aswell. She fondled them, playing the base rolling them around her fingers like marbles, and scratching the line of Tania's urethra with her nail.

Tania clenched her teeth and fists feeling like her soul was trying to get out of her body through her dick but something was blocking it. You looked up at Tania and saw how horny she was. By now she should have already came so maybe there was somehing wrong with her.

You figured it was because Sophie was touching her aswell that Tania couldn't cum without any guilt. So you directed her gaze to you with a smile and kissed her in front of Sophie.

Sophie felt both shocked and frustrated, her hand slowly started to make their way to her own cunt but she didn't want to lose this badly... She pressed her body against Tania to have a better access to her package, stimulating her balls, her veins, and even playing with the base of her gland.

Sophie's hands started feeling Tania's balls pulsing and her dick throbbing harder, you could see that Tania was getting near the orgasm so you started moving even faster. Tania couldn't handle anymore stimuli and finaly came undone releasing her load in the water of the bath with a loud moan muffled by your kiss.

When Tania's body started calming down you slowly removed your lips from hers and let the futanari rest on her against the bath wall while slwoly rubbing her shaft to let the full orgasm end.

"Can't you just... Cum faster...">Sophie told Tania who was obviously too lost to understand anything. Her hand was still on Tania's balls and could feel how they were pulsing underwater. She released them and turned the other way trying to calm herself while Tania rested back on the bathwall. "How annoying..." she murmured to herself.

You smiled when everything was done and looked at them. Tania was resting and Sophie was kind of washing her hands. It was really funny. You decide to hug the both of them together against you. Even if Tania was reeling from the ejaculation, she smiled and Sophie was surprisingly not disgusted by the hug.
