My two step-sisters are cute, but they're always competing with each other and don't get along. When I was having trouble with my step-sisters asking me which one of them looks more mature, they started competing with me about the size of their breasts, how they massaged them, and how good they were at kissing... Then they suddenly started deep-throating me, saying, "I'm more mature, so I can suck it in more," and "I can put it in deeper!" They competed with each other and did a double self-deep-throat! I couldn't stand the two of them fighting over my dick, so I shot it deep in their throats! When they saw my sperm, they got horny and asked me to cum inside them again and again!
