[A few hours earlier]
Marie waited for 15 minutes after Kitty had left for her afternoon out with Allan. Then she carefully packed a bag with diapers, onesies and all the other things that baby Jason would need for a few days with grandma. Lastly, she took the bottles of breast milk that were in the refrigerator that Kitty had left for her and packed them as well.
Baby Jason was a quiet baby and very easy to watch. Marie really liked her time here with him, but if Kitty's mom would take him, then she would have the rest of today free to spend with Derek. Mom and Dad were out of town for the rest of the week, so she didn't have to worry about sneaking around, and with her last favor repaid to Allan, she didn't need to worry about him spilling the beans to them either. All in all, it was shaping up to be a great weekend.
She bundled baby Jason up for the ride to his grandmas, then took the overnight bag and all the extras and packed them in her little Toyota. She had a spare baby seat that Kitty had given her in case she ever needed to go somewhere when she was sitting for Jason. She set it up in her backseat and then carefully got Jason seated and tucked into it all safe and secure. Then, she locked up the house and headed for grandmas.
Allan had been right; Kitty's mom was delighted for a chance to watch Jason for a few days. Marie showed her the note from Kitty and she didn't even ask any additional questions. She was just thrilled that she got to spend time with, and spoil baby Jason. She took the overnight bag and everything else from Marie, thanked her and then went off into the house to play grandma.
Marie was relieved that it had been so easy. She had been afraid that Kitty's mom would have had all sorts of questions about Kitty asking her to keep the baby for a few days and Marie wasn't at all certain that she could have answered them satisfactorily. But now she was free to go and spend her weekend with Derek. She jumped in her car and headed off.
Derek lived in a small apartment in a not-so-great neighborhood. That was only one of the reasons that Marie's parents didn't like Derek. There were also his run ins with the law and the fact that his parents were not really the sort of folks Marie's parents hung around with. To be blunt, her parents were snobs and didn't think Derek or his family was good enough for their little girl.
If only her parents could see their little girl naked, ass up in the air, getting reamed in her ass hard by Derek's massive 11-inch cock, they'd probably have a heart attack. Marie almost did the first time he had taken her from behind. Marie had never had anal sex before, but Derek was an ass man and really wanted to, so Marie had given in. In a way she was pleased she did because she felt it brought the two of them closer but in other ways it was somewhat of a problem because once she had done it, he wanted to do it again.
It had hurt so much Marie's first time that she had refused to try again, however Derek was getting more and more insistent and she couldn't put him off forever. Derek had even suggested trying some bondage, tying Marie to the headboard of his bed. He told her she would really get off on giving up all that control to him, but Marie was much more a dominant personality and didn't like the idea of being tied up for Derek or anyone. Maybe this weekend she could try to make him forget all that anal and bondage nonsense. She had an idea that maybe she could try to deep throat him. He was so big, but Marie had been practicing with a large dildo she had gotten online, and she thought she could, maybe, do it.
When she reached Derek's place, she parked and went to his door. He answered almost immediately, like he had been waiting for her right by the door. He grabbed her arm and pulled her inside, slamming the door and pushing her up hard against it. He pressed his body tight against hers and began kissing her, roughly. His teeth bit and pulled at her bottom lip, then released it and moved his mouth down to her neck, biting her gently at first and then with a bit more force. His hands slid around her waist and grabbed a hold of her ass and squeezed.
Marie groaned into his kiss and embrace. She felt a tingle run through her as his hands played with her ass, squeezing and massaging, but a part of her mind was just a little worried. She knew where this could lead, and she still wasn't ready to give Derek her ass again. She purred back at him as he nibbled her throat and rubbed her hips against his, feeling his cock already hard and ready for action.
This was the other problem with Derek. His first thoughts were always about sex. Marie loved the sex they had, but sometimes she wanted just a little bit of romance. She let Derek paw and kiss her for another minute or so and then gently but forcefully pushed him back. She gasped and took in a deep breath, flushed from his initial advances.
"Hey stallion," she said, using his nickname. "Hold up for just a minute and let a lady catch her breath!" She smiled at him using that sexy smile she saved for times when she needed him to do as she said.
Derek stepped back and grinned at her.
"What's the matter, too much for you to handle little lady?" he said teasingly.
Marie laughed and she did lean forward and kiss him, gently, on the mouth. When he started to push forward, she held him back.
"Now Derek, lets take it slow, OK? We have all weekend." She wasn't certain she was convincing him, so she added, "I mean, my parents are gone for the week. We can go back to my place and have the run of it. "
Now she had Derek's attention. Their house was much nicer than his and he had never been allowed to fuck Marie in her own bed. Plus, they had a pool out back. Marie could see the idea taking hold.
"Hey, but what about your brother?" he asked suddenly. "He's not gone all week, is he?"
Marie shook her head. "No, but he is gone all afternoon. He's out with a neighbor at a double feature and they'll probably go out for food afterwards. He won't be home till much later."
Marie wasn't certain what Allan was really up to, but since he had made her take Kitty's son to her mom's place, she thought he probably intended to keep her busy more than just a few hours.
Derek's eyes lit up when Marie mentioned her neighbor.
"Not that smoking MILF with the big knockers? Man she is way out of his league."
Marie agreed on that point but if Allan had set all this up, he obviously had a plan.
"C'mon my big stallion," she said taking him by the hand and leading him towards the door, "lets take this party back to my place." She moved his hand to her ass and let him squeeze it. "Who knows, I might even let you get lucky!"
That was enough to convince Derek and they headed out for her place.
When they got there, Marie saw that Allan's car and Kitty's Subaru was still in the driveway.
"Huh, that's strange" Marie said as they went into the house. "I thought Allan and Ms. Hall would be gone." She reached the stairs and called up. She got no reply.
Marie told Derek to wait for a few minutes while she looked for her brother. If Kitty was still here, she knew there would be a problem with her having taken the baby to grandmas without Kitty's actual permission. If anything came of that, she wanted Allan to deal with it. She made a quick circuit of the downstairs and even ran up to Allan's room, but no one was there. She came back down to Derek in the living room.
"That is so strange. Where could they be? They wouldn't have walked, the theatres at least a twenty-minute drive." Derek just shrugged.
"Do you have a basement?" he asked.
Marie nodded and for a moment almost ignored that thought. What would Allan and Kitty be doing in the basement. Then she thought she better at least look.
