My parents remarried and I suddenly got two step sisters! My step sisters are very timid and can't say no. I saw through their characteristics and boldly asked them if I could practice deep throating, and as expected, they didn't say no and let me do it. And when I thrust my hard cock deep into their throats, they said "Do more now!!"... They became masochists! At this point, I can do more than just deep throating! Next, I take the saliva-covered cock I thrust deep into their throats and move it to the back of their vaginas! And I can enjoy both of them at the same time! It's the best! I can't stop!
