Robert saw her hand headed between her legs and realized that his play was having the desired effect, and he was having fun with her nipples for the moment. He kissed her neck and behind her ears.
Nelly squeaked with surprise when she suddenly was faced with his big cock. "I wasn't doing anything. Would you please sit down?" She asked shyly as she turned her head away.
Nelly's whole face turned red. She was feeling quite flustered with his questions. Desperately she tried to think of an honest answer without saying anything too embarrassing. "I... I... moving around in the water?"
When she finally admitted it, he sat back down in the tub behind her and slowly lowered her over his cock. "That is what you really wanted , now wasn't it?"
Nelly fidgeted slightly when he didn't do anything else. Sure she wanted him in her, but she didn't want it to just stop with that. She wiggled her hips a little in attempt to get him to realize what she wanted.
Nelly moaned loudly as her breasts bounced with each movement. "Too much. If you do that, I won't last very long." Her pussy tightened on his cock as she got close.
