She is giving him a blowjob in her sleep

Samantha was sucking David's cock. She was nude and seemed to be much more endowed (ie she had grown a couple cup sizes) than just an hour ago. David was thrilled by this. It had been a few years since he had gotten head from his wife. He did not notice she was still sleeping at first. But he did notice the bigger boobs and her toned figure. The one she had had at 18.

"What brought this on, honey?" he asked her. She did not answer but continued to fellate him. She worked slowly, licking his cock and twirling her tongue around his cock head. Her sole purpose was to bring her husband pleasure. David looked down and saw his wife's eyes were closed and her clothing was lying in a pile next to where they had fallen asleep.

"That's great, honey. I'm gonna cum!" David spurted his cum into his wife's mouth. He knew something was amiss when she swallowed it without complaint. Samantha never swallowed. She spent a minute cleaning his cock and balls and then lied back down on her side. David saw that her pussy had a full bush, another thing that had changed about her. He did not know what to do. But he suspected it had been the strange fruit from the island. If he could get all the women on the island to eat it, who knows what would happen.
