I never would attempt to explain this one to Bob, but what had just happened was this.Ann was bothered by the way bob had stripped her of any control ...he last time he was here. It turned her on tremendously at the time, but then, it bugged her for the last four and a half months. She had been quite her normal self during the threesome. Sometimes submissive, sometimes taking the lead. In the Jacuzzi, she had played Bob like a cheap guitar. Then she walked away leaving him with a raging hard on,. She followed him, rolling onto her side, laying her head on his chest, sucking on his nipples, tasting his sweat, moving down over his tummy, kissing him as she sought her prize, taking his limp cock into her mouth, tasting the mix of cum and cunt juice as she gently nursed him.Eventually she released him, moving alongside him, snuggling into his body. “Tell me this won’t end,” she whispered. “Tell me you will always want me.”“Don’t worry Sis,” he replied, holding her breast and rolling his. And some part of him clearly wanted to know.Would they use up his youth and beauty, then discard the empty husk that remained? Or would his future master reward his submission, but allowing him to continue serving in a non-sexual way, when his youth and beauty were gone? Was he willing to bet his future on that hope? To leave, he would need courage. He would have to develop a spine. He would have to become a real man. Could he do that? “Snap out of it, slave! It's time to meet the building. You can barely move around." But I love my bears! Oh, all right. But if I win the bet, whatever it is, I want you to take me with you to San Francisco."No way I thought. It would be strictly me and Mark and his cock and my pussy. I didn't need competition. "Sure I will, Mary. If you win the bet, whatever it is."We got off the plane and checked into the hotel. I dragged Mary all over the city. The Reuben H. Fleet Science Center, Japanese Friendship Garden, Starlight Bowl, Mingei International.
