It’s your sister. You know I’ve always wanted her, and as she sits across the table from us at the family Thanksgiving dinner, you catch me making eyes at her. I feel a foot press against mine, and I don’t know if it’s yours or hers, but I press back. You reach into my lap and feel my hard cock, and then she winks at me and I know that there are plans in place that I’m not aware of.
Later we’re up in the room that we’re staying in for the weekend, the same one you used to sleep in as a teenager. We’re laying on the bed and we start to fool around. Once we’re naked, you drop down to the foot of the bed and start sucking on my cock. Quietly, the door opens and your sister slips in, naked. Your increased fervor tells me that you know she’s there, but you don’t acknowledge her. She’s a sight to behold, standing at the foot of the bed, sweat glistening off her skin. She watches you blowing me, and then starts touching herself. It’s too much for me to handle, and I shoot load after load of hot cum into your mouth and down your throat.
After you swallow, you climb up next to me on the bed, and beckon to her to join us. I’m already starting to get hard again with anticipation…
