It took only a moment for Becca to make this transformation and return to John. His eyes opened wide as he took it all in: her hair now a little wild,...her full naked breasts with their pink areolae and nipples standing proud above the skimpy bustier, the creamy flesh of her tummy and the bright red strip of pubic hair on her mons. She stood with her hands on her hips and legs apart. The boots were the coup de grace. John gasped and reflexively reached for his cock managing to give it one hard. I looked to my wife and she asked me to stay there.Feeling humiliated, I sat down on a chair as Ana began to unbutton her sundress. Soon she stood for a moment in her sexy little pale green bikini. Then she undid the top and exposed her round boobs to the black stranger.Her pink nipples were hard and erect, but I assumed that it was from fear rather than excitement. Then she turned her back to him and slid off the thong, showing her smooth ass cheeks to him.The man commented: “Nice, very nice. Sarah realises her predicament and knows she has no choice, she realised that whatever happens, she's going to be eating a bowl of cum one way or another and so reluctantly accepts the easy way, and opens her mouth for her teacher."That's what I thought," Mandy chuckles in delight, "Good slut."Mandy takes the spoon and feeds Sarah the spunk. Sarah really didn't like the taste of it so quickly swallows it, not wanting to keep it in her mouth for longer than she had to, and fighting back her. You must earn it!" With that you pump faster, and I move with you. Holding back from cumming but fully injoing the pleasure your giving me. "Fuck! Master please, it feels so good." You slow to a teasingly slow pace and I let out a whine at the loss of momentm. But try as I may, I can not move very well, the bonds hold me to the walls and I can not get enough leverage to bounce freely on your cock. "Please what my pet? Be spicific or I shall give you no pleasure at all tonight." I stop moving.
