The moment he started turning his back on others, he would be turning his back on her. That would put their love at risk faster than anything.In the m...rning, William and Lucy sat at the dining room table surrounded by books and papers. William pointed to a section of one of the papers and said, "I think that this is incorrect, but my math isn't good enough to prove it."Picking up the paper, Lucy read the section of the paper with care. Her mind entered into the mental space of mathematics in. I did not know what they were up to.They had told friends about this and I was obviously unaware that another running team arrived shortly after the loss of the video feed. There were 12 more of them.I was unaware my girl took a total of 12 loads of cum down her throat. She had taken 6 loads in her ass and 20 in her tight pussy by this time. She was so full her flat belly now looked almost pregnant.I had never masterbated for so long though. I watched and came several times as the boys. Now it also started raining very heavily and it was impossible to drive in an inhabited state! I requested her to book a hotel room nearby since it was too risky for her to travel back home, which was a wiser decision considering her state!!As I started accompanying her to her room, she slipped and was almost about to fall, which made me to hold her by waist .In the process her top was lifted which revealed her belly buttons and her blue panty strips!! “Holy cow” her belly’s were damn cute!!. "Mmmm I never thought you'd be touching my butt like this."Nathan lifted her dress up over her taking it all off. "Well, I never thought I'd be wanting you so much."Callie stood there completely naked. Even though the room was hot her nipples were hard. Nathan was almost breathless looking at his sister naked. God she looks delicious he thought to himself. Her breasts so firm, her tummy so flat, her skin so soft and delicate."Your so beautiful Callie. Oh man I'm falling more in love with you.
