She gives the ok... pussy it is

• Go ahead! Cum inside my pussy! It's safe. Fill me up with your sperm!

With her approval you push as deep as you can and unload your cum. Jet after jet spurts from your throbbing cock hitting her inner walls, coating them.
Feeling your throbbing cock erupt inside her pussy sends Tina over the edge. She starts to shake as her orgasm hits. She's biting her fist trying to suppress her moans.

• Oh my God! Oh my God! OH MY GOOOOOOD! She says her mantra as her knees turn to jelly and you have to hold her tight to prevent her from falling.

You are still holding Tina tight waiting for her to recover from her blissful high, both of you still panting, when guilt hits you. Images of your loving wife pop-up in your head making you feel miserable.
Now that your primal urges have been satisfied and blood manages to reach your brain, you realize what have you done. You CHEATED! You love your wife and she loves you too. You are happy with her... Than why did you cheat on her?! And with one of her friends nonetheless.
While you are pondering about what just happened, you feel something stirring in your arms. You remember that you're still holding Tina and it seems that she recovered from her bliss. The warmth of her body reminds you that both of you are still naked on the lower half.
Slowly, she removes herself from your arms. Your flaccid cock slips from the velvet embrace of her pussy and a string of your cum leaks running down her thigh. Than she bends to lift her panties back in place. As she does this you find yourself enthralled by her ass once again, all your previous thoughts of guilt forgotten and replaced by the dirty images of your cock moving in and out of that sweet looking ass.
Whilst you are dreaming with your eyes opened, Tina made herself presentable again and turned to face you.

• You'd better get dressed yourself and head inside before anyone gets suspicious. You don't want Audrey to find out what just happened here, do you!? I know I don't what that to happen, especially since I hope we can do it again... and maybe more. Tina said smirking and placed a loving kiss on your lips. I will follow shortly.
