Part 4

Sue was a bit disappointed when her sister, Mary and brother-in-law, Bob arrived. Her sexual romps with David would have to end. The taboo experience had awakened lustful desires. She felt like she was 18 again.

It didn’t take long to get into “tourist” mode. Sue was having a great time in spite of not getting to play sex games with David. They toured the local landmarks, hit all the scenic sites, and visited two state parks. The few days they had together flew by.

The morning before they were to return home, Mary got up early to do some last minute shopping and David went with.

Bob was trying to sleep, but a ringing cell phone kept waking him up. Curious, he finally found David’s phone laying on the kitchen counter. Two missed calls from his best friend Greg he noticed. “Odd that David would forget his phone”, Bob thought, “He doesn’t do anything without it.” Bob remembered the day he bought it for David and how David carefully opened the box. Together they did the set up, wifi connection, etc. He even remembered the pass code they put in; 0,9,8,7. He pushed the buttons and the phone opened up. As he set the phone down his thumb hit the touch screen and the photos opened up. Intrigued, Bob scrolled through the various pics enjoying himself. But when a photo opened of the hole in the door to Sue’s room, Bob took a sudden intense interest. Zooming in he could see Sue naked through the hole in the door. What had David been up to?

Walking down the hall with phone in hand Bob knocked hard on Sue’s door causing it to push open. Looking down he could see the absence of the knob and the vacant hole.

“What’s up?” Sue questioned as she approached the door.

“I have something I have to show you.” He said. “I hope you understand. I’m so embarrassed but you need to see this.”

“What could be so embarrassing Bob? Sue said smiling.

With that question Bob showed Sue the first pic taken through the hole in the door. She was undressing and down to her bra and panties. The next pic had her topless and the third totally naked.

“I’m afraid David has been spying on you.” Bob said. “I am going to take care of this as soon as they get back. He is going to get it.”

“Now wait a minute.” Sue replied. “The door knob is missing and that is my fault. I should have had it fixed. And he is still a teenager full of hormones. I understand Bob. It was an attempt to take a peek and his hormones took over.”

“But he didn’t have to take pictures!” Bob exclaimed.

“No, but all teens take pics of everything.” Sue said. “And actually, I find it flattering that he would take a pic of me. Who would think he’d want to see a 40 year old naked?”

“Well I know why.” Bob said as he scrolled through more pics. Bob came to pics of Sue on her hands and knees, naked, with her full tits hanging down seductively. The next pic was of her ass very close to the door. Then of her bent over with her pussy right up to the hole. Bob was mesmerized. The next pic was of Sue’s face close to the hole with cum dripping down her lips.

”I’m sorry Bob,” Sue said putting her hand on his shoulder. “Things got out of hand.”

“But, but it looks like you did, did, things with him.” Bob stuttered.

“Please let me explain Bob.” Sue consoled. “Please listen to me. Just be calm and listen.”

“Ok”

“He is a healthy teenager doing what is normal.” Sue explained. “And when I caught him peeking at me I was thrilled. He didn’t know I knew he was there. I should have been angry but I have not had a man around for years. I was excited that David was interested. Can you understand that?”

“I guess. I mean I get that.” Bob said. “So you liked it?”

“More than liked.” Sue said. “I loved it. It turned me on. I felt young and exotic.. I put on a show for him and that’s what you are seeing. I felt like I was a stripper giving him a lap dance or something.”

“But, but, this pic looks like, you know, on your lips.” Bob said.

“Well Bob, he pushed his penis through the hole and I didn’t do anything to stop him.” Sue explained. “I took advantage and that is my fault. I know better, but at that moment it just got away from me. I was living out my stripper fantasy. At the time it seemed natural.”

“This is going to be hard to explain to your sister.” Bob said. “And what do I say to David? He’s too old to spank.” Sue laughed at that.

“I think we don’t say anything.” Sue said. “That is what is best. It is our secret. David doesn’t know you looked at the pics and video’s. No one will ever know and that will keep the family together. Please don’t tell Mary. It just won’t work out if she knows.”

“He took video’s too?” Bob asked as he scrolled through the phone. The video he focused on was of Sue sucking David’s cock – but there was no door in between them. Then another teen showed up in the video and began fucking her from behind. Lots of cum shots. Loads of cum over Sue’s body. Bob was speechless.

“Let me explain.” Sue said. “They asked me to cooperate or the pics might end up on the internet.”

“They blackmailed you?” Bob asked to confirm.

“That sounds so sinister.” Sue said. “It was innocent. Just two boys looking to get a look at a naked woman that just got out of control. Can you imagine looking through this and seeing a naked woman for the first time. Here lets close the door and see what you think.”

Sue closed the door and began to stroll around the room seductively. She knew he would look. She knew he was hard from watching the video. She had to convince him to not talk.

Sue began a slow strip tease for her brother-in-law. When completely naked, she paraded around the room again. Sure he was watching, she got down on her hands and knees and crawled to the door. She watched her brother-in-law stare as she got closer. Her huge swaying breasts and wiggling ass were very persuasive. Sue opened her mouth and put it up to the opening. Immediately Bob’s cock came pushing through and into her mouth. The flared tip was so big that it barely fit through the knob opening. But no time for comparisons. Sue took it in and sucked.

Mouthing and sucking and licking the cock-head, Sue shuddered in pleasure. Bob pushed harder until Sue could hold the shaft in her fist and still have the entire flared tip in her mouth. Bob pushed harder and Sue gasped in wonder.

Pulling her mouth off but continuing to stroke Bob, Sue said, “Can you just imagine how David felt? Can you feel how I feel Bob? I crave male attention.” With that Sue returned to her oral assault on Bob’s cock-head. She wanted to tear the door down and feel him inside her. Bob was pushing faster and swelling in her mouth now. The eruption followed quickly. Sue continued to suck and lick him.

Completely out of breath, Bob pulled out of the door and gasped. Sue opened the door and said, “Now you understand how this can happen.”

“But what about the one from behind. Who was that anyway?” Bob said.

“Never mind who he was. If you must know he’s David’s friend, a neighbor, and I know him too.” Sue explained. “Things just happen. It’s OK. You have to trust me.”

“But some of that is no accident!” Bob exclaimed.

Sue then got down on her hands and knees. She crawled so that her ass faced Bob and jiggled her rear end. “Now can you imagine watching me suck your friend’s cock. What would you do?”

With that Bob got on his knees behind her and slid his cock into her wet pussy. And it felt good. Bob fucked her like a teenager. His long, thick cock was tight inside his sister-in-law. Sue twerked her ass as Bob pumped. His cock felt bigger on each thrust. Pulling out suddenly, Bob flipped Sue over to her back and drove his cock into her again. Her legs locked behind Bob and their bodies slapped together lewdly.

“This is how it happens every time.” Sue said. “Please don’t tell.”

Bob continued fucking her. Groaning and slobbering like an animal. Sue knew he couldn’t talk now. She just took pleasure in being fucked by her biggest cock ever. Bob pulled out again. This time he climbed on her higher and slid his cock between her double D’s. Sue pushed her tits around his cock as he fucked. Her tongue lapped at the tip as his thrusts extended. Cum shot out covering her face. “Lick it!” Bob commanded. “Your sister never swallows it! Suck it all Sue, suck it!” Sue was never happier to be obedient.

Bob got up standing over her, grabbed David’s cell phone and took a pic.

“What the hell was that about?” Sue wondered. But satisfied and relieved, she laid back with a smile. Her face still covered in cum. Bob walked out of the room picking his clothes off the floor.
