Alex loved the beautiful sight before his eyes. His twin sister was naked, kneeling on the bed with her head down and her lovely butt sticking up in the air. He could barely contain his joy when his father asked him to approach the bed so that he could learn more about his sister's body. It was awesome enough that he was seeing his sister naked, but now he was ecstatic that he was actually going to get to touch her intimately. Melissa didn't give any indication of it, but she too was excited about her brother seeing her like this. Alex sat down on the bed right behind Melissa's protruding butt. He looked at this father anxiously for further instructions. Mr. Robinson caressed his daughter's reddened buttocks with his hand.
"OK son, look at how I am rubbing your sister's butt. I am sure she will enjoy it more when you do it. The breasts and reproductive organs are not the only parts of a woman's body that are susceptible to pleasure. Many men find an attractive looking butt to be very appealing on a woman, and many women enjoy a man's attention to her butt. I just finished spanking your sister. Of course, rubbing after a spanking is appreciated because it helps with the pain, but I'm certain that most of your sister's enjoyment is due to an entirely different cause. The Bible makes it clear that women are submissive creatures. Melissa had to expose herself and submit to chastisement, the biblical way, from a man in an authority position over her. This submission to punishment is likely to have a profound impact on her sexuality. Her hormones are in overdrive right now. She is in a vulnerable position right now, and as such, her body is crying out for a man to comfort her and assert his ownership over her. Your touch on her butt will be very welcome. Go ahead. Before you are allowed to pleasure her nipples and reproductive parts, you are going to learn how to take care of this pleasure zone. I cleaned her up for you. Rub her any way you want. Just don't stick anything in her anus yet. I will step aside now. Get to work."
Mr. Robinson stepped away from the bed. Alex nervously cupped his hands around Melissa's buttocks. She flinched with pleasure at his touch. Alex squeezed gently. Then he squeezed harder. He wasn't sure if she liked it gentle or hard. He mixed up his movements. Alex turned his wrists around and used his fingertips to graze over the seam where the lower part of Melissa's butt connected to her legs. She seemed especially sensitive there. Alex thought she liked what he was doing, but he couldn't be sure. It suddenly occurred to Alex that he should be talking to his sister.
"Melissa, you have a very nice butt. It's beautiful back here."
Melissa didn't think she could blush any more than she already was, but somehow Alex's compliment did just that for her. It took away much of her anxiety to know that Alex could appreciate every part of her.
"Thanks Alex. I'm really glad you like it."
"Yeah, I do. Does what I'm doing make you feel good? I want you to enjoy this."
"Yes, I'm enjoying this very much. You are doing great."
