You figured since Claudia liked feet, why not have her "clean" Sienna's feet for her while you watched? "Claudia, would you like to lick Sienna's feet clean for her?" you asked. Sienna gave you a look, complete with a "Huh?" response of you making the offer without saying anything to her first. Claudia nodded and then eagerly grabbed one of Sienna's feet to lick. However, she hesitated, looking at your cum that covered the foot. She seemed uncertain a little, but taking a deep breath first, she went right to town licking Sienna's feet for the second time tonight.

"Hey, (your name) Why are you letting her have the best part after I'm the one who brought you the pleasure of cumming?" Sienna asked as she watched Claudia, turning her foot and spreading her toes occasionally to assist her. Though she was slightly helping her, you could see a faint annoyance in her eyes. Could Sienna be jelous perhaps, that Claudia was getting your cum? Claudia switched to licking Sienna's other foot and as you watched, you started getting hard again.
"I just thought it would be the polite thing to do to let her have a taste of it since she's been serving a mistress for so long." You told Sienna. She sighed, seemingly disappointed. "But I made you cum. It kind of isn't fair." she said, her annoyance now predominant to see. Trying to be nice, you told her she can have your next load. Claudia was now sucking Sienna's toes, although her feet seemed clean now. Watching made your dick continue to swell, you were now almost at full hard-on. "Well, I really don't want to wait much longer. So how does a blowjob sound?" Sienna asked you. Her offer took you by surprise. Just a short while ago, she gave you an amazing footjob, and now she was offering to blow you.

You didn't even have to think about it, you whole-hardheartedly accepted. That sounds great Sienna, if you would like to, then go ahead." You said, trying not to sound too eager while shifting your hips forward to allow Sienna better access to your member. Laying on her belly, propped up with her elbows, Sienna got right to work. Her position allowed her between your legs while Claudia could still access her feet. She started simply by licking up the remaining cum off your shaft from earlier, then she started circling the head of your cock with her tongue. After she done this for a few seconds, she went right to the sucking, engulfing about 3/4 of your whole cock in her mouth and bobbing her head up and down.

For some reason, maybe from enjoying sucking you off, or maybe from something Claudia was doing with her feet, Sienna moaned into your meat, which sent vibrations through your member and to your very core. The pleasure of this made you shudder. Sienna wasn't just excellent at footjobs, she was also a pro at blowjobs too! You could tell you wouldn't last long with her skills. You ran your fingers through her hair as your eyes darted between watching Sienna suck you and Claudia worshiping Sienna's feet. You were almost envious of Claudia for getting to Sienna's feet. Almost, except for the fact you'd cum on her feet and weren't keen on the idea of tasting your own cum.

You felt the pressure building in your balls, signalling your climax was fast approaching. "Sienna... you're doing an amazing job!... Please.... don't stop. I'm... About to cum..." you managed to utter. As if you weren't horny enough by the current situation, you just then noticed Claudia had her hand down her (Well, technically Sienna's) shorts! Your body went stiff as your cock erupted, shooting wave after wave of cum into Sienna's awaiting mouth, which she gulped down as fast as she could. A little bit of cum dribbled out of her mouth as you released your last couple shots, then Sienna pulled your cock out of her mouth and wiped the cum off her lips before licking her fingers clean.

After this, you were completely spent, panting and actually having a bit of weakness. You needed to rest for a bit before you could continue... Damn Sienna was good! However, just because you needed to rest, didn't necessarily mean that the girls had to as well...
