I spread her pussy so you can see where the cock goes in.

Look closely at the opening where I usually insert my hard cock. Imagine it is your cock and how it is tightly enclosed in this wet pussy. How the mistress enjoys it when it's all the way inside her so she can feel it against her cervix. Her pussy sucks lustfully on the cock until your entire sperm supply is in her uterus.
