I confirmed her suspicion, desperate to keep my voice and resolve from cracking. “Light erotic spanking helps to promote stimulation of the blood ve...sels. Inflammation of the buttocks causes the diversion of blood to that region preferentially over other parts of the body. Given the relative proximity of the buttocks to the genitals, this also helps to trigger and stimulate feelings of sexual arousal. Mild sensations of pain also trigger levels of dopamine in the brain….” I interjected.. That night on her way home, Summer went by the local Victoria's Secret store and she'd been weighed down from all the items she'd purchased with the intent of seducing Philip in days to come. She could hardly wait for the days to pass so she could wear and show Philip everything she'd bought to make herself look sexy and desirable for him.The next morning after their first fuck experience, Summer didn't waste any time. After she'd put her personal items and her purse away in her private work. He asked if I didn’t mind and I said “of course not. With that he undid his belt and zip and as he slid his trousers and pants down a superb rock hard cock flipped out and up against his stomach with a very swollen red helmet. He had a tiny thin patch of pubic hair but the length of his cock went over the top of it. “Can you shoot” I asked as he began slowly rubbing his cock and he said “Oh Yes”. I couldn’t resist and asked him if I could feel it and he nodded. I reached across and took hold of. “Ma?”“Why was it up like that?” she was referring to my dick, “Do you always think this way about me? You know we shouldn’t be doing this, right?”Why was she asking me this now? She was the one who grabbed it in the first place! She was the one who walked to the closet topless and came back with the smallest and tightest black lace bra! She was the one who called me in to hook her bra as if nothing had happened. How could we have been normal? How could I just hook her bra like I was a kid.
