My birthday tiara flashed as the LED lights blinked on and off. I giggled at you, starting to blush. I remembered what you had said you were going to ...do to me when we talked this afternoon; just thinking of half of what you said made my panties wet. “I’m good. I’m better now that you are here though.” I said, kissing you and pulling your bottom lip between my teeth and tugging. It was your turn to blush now. “Really, just because I’m here, your birthday is that much better?” You asked.. ’ She lied.Karen looked down at her blushing daughter and knew better. ‘So did you cum yet darling.

Then after a few minutes I settled down, relaxed and enjoyed the ride. I rested my feet on his legs as he fucked my asshole hard, my tiny soft dick flopping.
