I want to show off to my twin sister how hard my slave cums for me. I start with a handjob showing her how hard you get and how you cum for me. I lick it to make it hard again and she is shocked at how fast you are throbbing hard for me again. She wants to try it herself and strokes your dick. She loves the feel of it. When you cum for her, she eagerly sucks it, and then we share your dick licking it from each side. My sister wants to try you again, and she's been a good girl and earned it. But she isn't allowed to fuck you when I'm out of the house! But my sister winks once I leave letting you know she's going to get that hard cock in her pussy soon!
