A few months later, Christy had actually moved to town. I kept at it with Debbie, naturally. Like I'm going to give up sex with a married sister who loves it in her sweet, tight ass and swallows at the drop of a... belt. I also kept at it in terms of trying to get Debbie to tell me where she'd met Christy. She finally admitted she found her on a web site devoted to unusual kinks. Turns out she was keeping quite a few people entertained with carefully modified tales of her tail, and how she gave it to her brother with her husband's encouragement.
I was shocked that she'd do that. I carefully explained to her that this was a serious violation of trust, and a breach of my privacy. I told her in no uncertain terms that she was a freaky slut to a degree even I hadn't appreciated, and she really should have let me know first and made sure I was okay with it, despite her assurances about changing names and facts to preserve our anonymity. This was very serious business.
She might have bought it if I hadn't been fucking her butthole at the time. And taking pictures to send to her husband. Communication is full of subtlety and pitfalls, whaddaya gonna do?
So I understood things a lot better. Christy had harbored a fetish ever since she turned nineteen and overheard a girlfriend talking on the phone about fucking her brother. Christy was an only child, but she'd wished for years that she had a brother, and she could seduce him into an incestuous affair. Debbie had realized that my fetish and Christy's desire -- and her own desire to watch, and play with a woman -- all fit together like the pieces of a fine watch. Or the pieces of an incestuous triune relationship.
Christy and I were straight up dating, almost like normal.... perverts. We'd go on dates, occasionally dropping sibling comments to each other, and if we were really adventurous, hinting at it with waitresses or other people we encountered. And when we were in private, Christy and I laid on the sibling sex theme as hard as we could. It drove both of us crazy. We often forget it was all an act, it meant so much to us and Debbie encouraged it so well. To us, we were incestuous siblings at home, and a couple with an incredible secret when we were out and about. Debbie hadn't joined us again, but she was kept informed by Christy. They had become very close.
Christy and I weren't just framing our fucking. Don't get me wrong. We were actually dating. She spent a lot of nights at my house, but she was also a real girlfriend. We were very compatible in more than our secret fetishes. She loved riding my motorcycle, we had the same taste in TV shows and food... it was great. Our dates usually ended in sex of course, but the first time it didn't Debbie came running. The second time too. The third time though, she didn't!
'You're getting spoiled. Well, so am I but you shouldn't complain, you should keep your sister happy. We won't let you get too blue, brother dear.'
Odd, but she had a point -- I shouldn't complain. I was fucking two women, and the slowest week in the last couple of months was three time. Most weeks it was two or three times with Debbie, two or three times with Christy. Hell, I sometimes took an evening to just rest and hydrate!
When Christy had to go out of town for a few days, I sent a message to Scott. 'Send your wife over.' I was starting to wonder if he'd gotten it when I heard a car outside.
I opened the door just as Debbie reached for it. She started to walk in, but I stopped her. "Give me your phone."
"What?"
"You once said to make you earn it. Here's how, tonight. Give me your phone." I emphasized my point by touching the barbell in her nipple. It was under her blouse and her bra, but from the way she bit her lip I knew she was focused on the piercing she'd gotten to earn her first vaginal sex with me.
"Okay. Make me earn it brother." She handed me her phone. I turned it off and put it on the table near the door. I told her to strip, and she did. I closed the front door, took her hand and pulled her to my bedroom. She followed me and knelt without being asked when I turned around. I had her get up and undress me. She pressed her body to mine as much as possible while she removed my clothes. She got right back on her knees when I was naked. She really wanted me in her mouth.
I held her head in my hands, just enough to keep her under control. I brushed my knob over her lips. I pulled her forward, and my erection rubbed her nose, bringing my balls to her chin. She nuzzled against me. I watched a drop of precum form, and guided my helmet to the tip of her nose. I left a shiny dot on her nose.
I pulled back and aimed lower. I watched my sister's lips open to accept my manhood. Her soft lips engulfed me, and I had to tighten my grip on her head to get just what I wanted; a long, slow, drawn out penetration. I held myself deep for a moment, then loosened my grip. I stroked her hair as my sister sucked me. She ran her lips up and down my shaft, stroking my balls and rubbing her own body. Sucking her brother's dick was clearly getting her off. I had prepositioned my phone, so I took a picture and sent it off to her husband.
After a while I got a better grip on her head. I forced myself down her throat, held it for a second, and slowly withdrew. Debbie looked up at me with an almost pained expression.
"I need a massage" I told her. "There's some oil on the nightstand." I stretched out on the bed on my stomach. Debbie got the oil, warmed it in her hands, and began giving me an excellent back rub. And breast rub. She almost got off by rubbing herself on my calf, but I stopped her.
"Concentrate, sis."
"Really?"
"Really. My shoulders need more attention."
She moved up, taking her wet, hungry pussy too far from my calf to let her continue. She wasn't doing as well as before. Distracted, I guess.
"Okay, clearly you need to focus more. Come on. Work those trapezoids."
She shook her head and got down to business. "Much better."
When I was good and relaxed I told Debbie to lay back. She did, eagerly. She grabbed her knees from the inside to hold herself open.
"And just what are you expecting?"
"Well, I'm hoping my brother is going to slide his fat cock into his sister's bare pussy. The pussy that only he gets to use au naturel. The pussy my husband has to suit up to enjoy. Please?"
Fuck, I loved the things she said when she was turned on.
I got between her legs aimed, and slammed into her. I jammed my rod in her, all the way to the hilt, in one forceful thrust. She screamed and wrapped her legs around me. I gave her three or four slow, gentle strokes, then slammed her pussy again. She was grinding and babbling underneath me, loving the feeling of my cock going from gentle and slow to savage violation.
When I was sure she was so wet it was dripping down from her pussy, I pulled out. She bit her lip and stared into my eyes, spreading her legs as wide as they could go. She knew what was next. I rubbed my knob in the little pocket where her anus lived. She took a deep breath, and I began to penetrate her. She'd gotten good at giving me her ass. Soon I was sliding into the hole that no one else on earth had ever experienced. When I was halfway in I slowed to a crawl. We were both breathing very deeply, and with every inhale I gave her another fraction of a millimeter. The pace was driving us both crazy. It took forever until I felt my sack brush against the valley between her cheeks. I got a picture of my rod fully engulfed in her rectum. Then I slid all the way out.
"Well, that's enough for tonight." I said, smiling down at my sister.
"What!? You can't -- come on, fuck me! Fuck this ass!"
"Kind of tired..."
"Seriously, you can't get me all revved up like this and just give me one pump -- it was hardly even a pump, it was so slow! Come on, pound me!"
She rolled to her side, licked her fingers, and starting thrusting two of them in and out of her slick back door. Fuck, she was sexy. I changed my plans a bit, and slid in behind her. I spooned her, and she grabbed my erection and guided it back to the heat glowing between her perfect cheeks. Her ass accepted me, and her long, slow exhale told me how much she'd wanted her sodomy. When I was all the way back in her ass, she whispered "thank you brother" and pulled an arm around so I was groping her breast. I set up a slow, rocking rhythm driving my manhood into her hot, clutching bowels.
