Ashley pulls out all the stops

As the movie began, Mark couldn't help but wonder how long it would take for his sister to make the first move. He didn't have to wait much longer because about three minutes in Ashley changed positions from sitting cross-legged to tucking her legs underneath her and leaning against Marks shoulder. Slowly over the next 30 minutes Ashley inched closer and closer until eventually Marks arm was wrapped behind her shoulders and her body was pressed tightly to his.

As the action in the movie got more intense Ashley wrapped her arms around her brother and hugged him tighter and tighter until a major jump scare where she screamed and jumped into his lap completely. Mark was doing his best to ignore his sister but that was proving quite difficult as her petite, nubile body continued to press up against his body. It certainly wasn't helping that with her sitting in his lap and with every little scare, Ashley would fidget causing her ass to rub against his dick through their clothing. He knew she had to feel his hard cock against her ass, in fact, it seemed the harder he got the more she moved around.

As Mark felt he was about to burst, he was afforded some reprieve as Ashley leaned forward off his lap to reach for her glass wine. As she brought the glass to her lips Mark saw it slip from her fingers pouring wine all over her top and shorts. "Oh no!" Ashley said, "hold on and pause the movie, I need to go get changed." Mark silently thanked the heavens that he'd have some sort of break from his horny sister. His relief didn't last long however, and he silently cursed under his breath when he saw what his sister was wearing. "Hey unfortunately I've been putting off doing laundry so the only clean things I have is my panties" Ashley said. Now his sister was decked out in a matching bright red, lacy bra and panty set. "Oh and I also brought us a blanket because it's getting kind of cold" she added with a giggle. Much to Mark's relief, Ashley didn't resume her old spot on his lap. Instead she took her old position of wrapping her arms around his body and resting her head against his chest. She also laid the blanket over both of their legs.

As the movie was finishing up, Mark felt movement under the blanket. Then he felt a hand brush against bare skin right above his cock. While Mark was focused on the movie, Ashley had stealthily unbuttoned his pants and pulled down his zipper underneath the blanket. She was in the process of grabbing his junk when he had felt it. Throwing the blanket off his legs and quickly standing up, Mark started leaving the living room. Ashley had been leaning up against her brother so when he moved she fell face down on the couch. "Okay, movies over. Exams tomorrow. Time for bed." Mark quickly said as he rushed upstairs, not bothering to look back at his disappointed sister. Running upstairs, he made it to his room and quickly locked the door behind him. As he looked down at the tent in his pants, Mark realized that playing hard to get was going to be a lot harder than he thought.
