Umbreon gasped and whimpered loudly as she rode Zack's cock. Thanks to Espeon's treatment, she was definitely getting close to cumming. She felt Zack's cock twitch like crazy before he came inside her, easily flooding her womb with the hot substance and making her buck her hips wildly to try and cum as well. However, Zack had stopped her before she continued, getting her to move off of his cock as he turned his attention to Espeon once again. Espeon grumbled a little as he came to her, her pussy so wet and aching for release.
When he had suddenly flipped her onto her back, she thought for a moment that he might just give her attention anyway, but she still hadn't convinced her sister yet. Umbreon happily moved over to sit over her sister's face, pushing her dripping pussy to her lips as a bit of their mixed fluids already started to drip into her mouth. Espeon whimpered underneath, but she would do all she could to make her sister cum and have Zack tend to her needs. She parted her lips to run her tongue over her sister's slit, getting a lovely groan from her as she started to buck her hips. Espeon also tried to nudge against Umbreon's clit every now and then, which got her to roughly thrust her hips down on her sister's face to try and get her to reach deeper.
