I was asked by my sister Carolynn to house sit their pets while her family went on Spring Break. I had done this a number of times before so agreed again. Only this time unbeknownst to me. She had added home surveillance cameras inside and out. Here I thought I had free reign and privacy. I was walking around in different states of undress. I was watching porn on their big screen TV and masturbating in several spots through out the house. Only to be discovered.
Carolynn had the ability to check in on things over an app on her mobile phone. Whenever a door opened or closed she knew about it. She could speak and listen over an intercom system discretely. She never let on while away that I could and was being watched at any given moment. That is until she got home and we spoke privately.
The conversation began innocent enough. She asked "What did you do all week?" I told her I worked during the day. Followed the pet's feeding instructions left behind. Was online and watched some movies. Then she held up her phone. On it was a screen capture of a picture of her living room and on the TV was an image from one of the Bi Sex films I had watched. Shocked and embarrassed, I asked her "Where did you get that?" She pointed right in the corner of the room. She explained the security system also has cameras in it. Every room in the house except the bathrooms.
Then she began teasing me about my choice in films. She had a series of screen captures for me to view. Look at this naughty cocksucker, as she showed me an image of a guy sucking off another. She asked me "Is that your thing big brother?" I just stood there and took it. Then she said "Nope, there is your thing." As she scrolled through her camera and revealed a picture of me, hard on in hand. I was busted dead to rights. She witnessed it and had photographic proof. I was feeling guilty, ashamed, and violated. Then all that changed
It turns out little sister has a naughty streak in her too. First she told me that she is a bit of a freak sexually. That she masturbated to her photo discovery of me. That the idea that I may be bisexual excited her. Then she asked me if I would help bring a fantasy of hers to life. I told her I liked where this was going but I would need more information first.
Carolynn has been dating a guy named Sean since she dumped her ex. For the past couple of years now she has wanted the two of them to have a mmf 3some. That she wanted to see Sean get it on with a guy. That he had agreed to it early on but they could not find anyone they trusted to keep their secret. She thought about it for days. That I would be the perfect candidate. If I was willing. My response was "Are you serious?"
She replied "Come on let me show you how serious." She peeled off her top saying. Let me make a down payment on what's to come. Then she stripped down to just her thong. Her spring break bikini tan lines were very visible.
She unbuckled my pants and reached into my underwear. I had gotten very hard very fast. She commented on my size, saying "The camera didn't lie." She tugged my pants down past my knees. She leaned over opened her mouth and blew warm air on my cock and balls. And without hesitation she took half of my cock in her mouth. God it felt great. I never thought this would ever happen. Let alone be her idea. Carolynn dropped to her knees. Using only her mouth she gobbled more and more down. Her hands were caressing my body. Everywhere from my thighs to shoulders front and back. Little sister knew her way around a cock. Gobs of saliva from the back of her throat ran all over my skin. I held her head in place and slowly fucked her mouth. Deeper and deeper. All the way to the base. Her tongue lashed out swiping my hairless balls. It eventually became to much. I tensed up and announced I was about to blow. Carolynn backed off my cock leaving just the tip in her mouth. She worked the head with her lips until I splashed the inside of her mouth with my cum. Then she worked my whole length back and forth until I had to step back because I could not take any more.
