Wait to say it.

Sarah looked past and nodded. Sarah started to finger you while Elena started rubbing your clit. They claim your tits, Sarah having the right and Elena having the left. You moaned loudly as Sarah got rougher. You always thought she was gentle, but over the next thirty seconds you changed your mind and now thought Sarah is acting innocent and gentle as she made you scream.

You saw her eyes change and fangs flash as she got as hard as she could, while Elena rubbed your clit furiously. You were lost in the pleasure, and heard them faintly coaxing you into confessing your love for Sarah.

"I love you Sarah!" you shouted as you cum hard, tensing then shaking. The orgasm made your tits jiggle, which Sarah stared at, before sucking them.

"There we go." Sarah licked your juices off of her fingers, giving some to Elena "Elena, get naked." She got up and watched your sister stripped down naked.
