My gf of over a decade does that also lol. We both love that she's a cock tease. But she makes sure I'm knowing that friend is going to be pumping her full of his hot cum after he has fucked her hard and longer. He's almost 2 in bigger n a little bit fatter and she absolutely goes crazy on the occasions they do. Love the fact I'm going to be eating her beautiful clean shaven tight pussy out and sliding in her with my friends cum coating my dick as I'm sliding in much easier.
I forgot to mention in my previous comment that my wife confessed that our friend's cum load felt extremely warm as he ejaculated deep in her pussy and she slept like a baby with his adulterous semen deep in her birthing canal.that night. It wasn't until the next day that she confessed the affair and the probability that she might be fertilized. She was still oozing his voluminous cum load the next day and admitted that his semen was thick and it had clung to her vaginal walls like glue. She also admitted that she might have made a big mistake by having sex with a guy who she didn’t have a lot of sexual affection for because she might be having his baby. We are counting the days now since the affair happened.
