Let the girls do their thing

John closed the door behind him and grinned as he walked downstairs. He could smell fresh popcorn so he peeked into the kitchen. Sarah's sister Nichole was there preparing snacks for their movie night. Nichole was taller than Sarah even though she was younger, and just as pretty. Nichole had long dark brown hair and was a little chubbier than Sarah which gave her a very curvy look. Her puffy cheeks gave her a deceptively innocent smile. John found it hard to believe that Sarah had told him Nichole had already had two different boyfriends this year and broke up with both of them. Apparently she has high standards in men.

John decided he wanted to let the girls start their movie night normally and have some fun along the way. He snapped his fingers and made it so that neither of the girls would notice him until he wanted them to. As he was admiring Nichole's plump ass and thinking about how he had not gotten off yet after all the teasing he did to Sarah, John heard the shower start upstairs. Sarah was going to be a few minutes so John thought of something fun to pass the time.

Since Nichole would not notice him, John walked up behind her and grabbed her butt. It felt nice but only briefly as she turned and walked away. What? She shouldn't have noticed me, thought John. Oh, she didn't, she's still getting dishes out for snacks. John snapped his fingers one more time and made it so that she would notice him only while they were both in the kitchen and she would not stop him from touching her anywhere he wanted.

"Oh, hi John." she smiled in greeting as if he had just walked into the room. "I didn't know you would be joining us."

"I'm not, I was just here giving your sister the best orgasm of her life." John said as he reached out and grabbed Nichole's right breast. She looked at his hand in shock, but did nothing to stop him. "That's why she's taking a shower right now." John squeezed her breast and found her nipple with his thumb, it was already poking up a bit.

"Please don't do that," Nichole pleaded, "My breasts are very sensitive and it's been a while since I've had a boyfriend." She begged, beginning to pant a little.

Encouraged, John cupped her right breast with his other hand began working them both in sync. "I still haven't gotten off yet, maybe you can help me out?" he asked.

"Ew, no, you're my sister's boyfriend and besides, you're not my type." Her voice getting breathy as she was clearly getting more aroused by John's actions.

"Really? What is your type?" he asked.

"None of... Ugh. None of your... ah! None of your business!" She was clearly very frustrated at the situation. She was waving her hands around her chest like she wanted to pull his hands away but couldn't bring herself to touch them. "Gah! you are such a dick! Why are you doing this?" She pleaded.

John noticed her hips were trusting against the air now too. "Well, I just thought maybe you could help me out." John said as he snapped his fingers, "How about we help each-other? I'll sit on the counter here and you can squeeze out some of my man-butter onto that popcorn you just made. If you can manage it, I will allow you to hump my leg here and it will feel like the best sex you have ever had."
