It was the best sleep I'd had in years and no hangover to boot! Sis and I had done something we should've never EVER done, and we didn't care. Here I was, lying next to the most beautiful woman I'd ever made love to, knowing it was the ultimate taboo, and all I could think of was making her happy.

Her taste was still on my lips, and the slick yet sticky feeling on my cock from her love juices only made me excited instead of my normal "I need to clean myself off" mode. She happened to roll over with a smile, then a fearful look upon seeing me naked on the floor next to her.

The look turned to a smile when she saw me smiling at her. She hesitated, then kissed me tenderly on the lips, laughing when she realized she'd tasted her own love juices on my lips.

"Hey... now this is a situation, isn't it?" I joked. "So BIG brother... where do we go from here? Is this an "oops," or an "ok to more?" She asked. I didn't respond with words... rather, I leaned over but instead of kissing her, I started to nibble on her neck very lovingly while I started to stroke her pussy very gently between her soft and slightly sticky lips.

I told her to stick out her tongue and said "this is as close as I get to being gay, so enjoy," then I sucked on her tongue like she'd sucked on my cock, even licking up and down it and deep-throating it. Between that and the fingering I was giving her, she couldn't take it and started to cum again. This time however, we couldn't use alcohol as an excuse. We KNEW we wanted this - and BAD!

She started to push me over, straddling my face. She held her lower body over me, placing her now swollen clit in line with my tongue and she started to suck on my rock hard cock like it was oxygen and she was in space. The dog had woken up too and though sis had looked like she was gonna have second thoughts about a second time with the dog, she felt the dog's tongue lick her slit at the same time it tickled my nose, making me laugh at both the feeling and the sight.

I decided to see what would happen now that we were both sober and had no excuse other than being horny, and boy, did she show ME what was next! She saw that I was getting turned on by watching that nearly six inch tongue go in and out of her pussy so she made me move and laid on her back while the dog slid the tongue in her like a wiggly flat cock. She used her love muscles to suck the tongue in while she continued to suck my own cock.

The sight of my little sister with a tongue-cock in her and my real cock in her was too much, and I shot and shot and shot so much cum that she was probably drowning but didn't care as her own orgasm overrode all else. She swallowed all of my cum then turned her ass and pussy towards me and told me to get hard quick! I told her that I needed a few minutes but that if she wanted to let the dog have "round 2," "go for it!"

That's all she needed and this time, she got on all fours like a dog in heat and I guided his doggie cock into her. This time, she KNEW what was coming and drove toward it like an engine with a huge piston driving inside.

The dog must've thought he was making puppies and his life depended on it, because I'd never seen any creature fuck another like that! For the first time (since it was daylight and not drunk), I saw that huge cock impaling my petite little sister. It was an amazing sight, and I realized that I was getting jealous! I may have been getting turned on and horny as hell, but someone else's cock was in her and not mine.

I decided to do a repeat of last night and had her lie on me with my cock in her ass while she had the dog fuck her from the front. The feeling of the dog cock and my cock sandwiching her love tunnel walls was too much for any of us, and the dog stopped and suddenly came, while I came again, causing sis to scream bloody murder while she came as hard as possible, head wagging left and right and howling like a honest to goodness bitch in heat!

Strangely enough, neither one of noticed our cousin Annie standing in the doorway (Annie and I were temporary roommates until her husband came back from a deployment in the Marines). There was no way we could hide what we were doing and no possible explanation, but beyond the shocked look in her eyes I saw something more so decided to take a chance...

"Annie, wanna play too?" I asked.

"But..." She said, hesitatingly but somewhat seductively. "I'm married."

Not "you're fucking your own sister!" or "you two are fucking a dog!" but "I'm married." I took that as a hopeful sign and said, "Then I guess we'll have to make sure nothing that happens is your fault, right?"

Before she could say another word, I walked up to her and, taking a scarf from her drawer, blindfolded her. She giggled as I slowly kissed her neck and cheek, then slowly started to both close the door which was partially open to the world outside and started to slowly open her blouse.

Behind me, I heard the audible "pop" of the dog's cock know coming out of sis, and now she wobbled a little bowlegged toward us, still lustfully looking at my cock and sliding her finger over her clit. While I enjoyed this new player who I'd only looked at as a cousin a day or two before, my sis who I never knew had even kissed a girl had started licking up and down Annie's love slit through her panties.

I could almost imagine the hard clit approaching the silk as my hand went down to Annie's ass, realizing that like many girls now, she was wearing thong panties and unlike most girls I knew (but like my beautiful sister), had a perfect ass. I pressed a thumb into her asshole, pressing down making her clit press hard against my sister's tongue. The constant stimulation and not being able to see who was doing what to her was having an effect on Annie.

My cousin started this low moan that kept getting louder and louder until she started to cum almost as loud as sis did with the dog in her. As she came, sis and I lowered her onto the floor and watched as her cum flowed out of her onto the floor and onto sis' hand since she was fingering Annie on the way down.

Unlike my original miracle from the night before, sis was taking charge. She took a dildo I found in Annie's drawer and started to slide it gently into Annie's sopping wet pussy. I watched in amazement as I saw my little sister please my cousin on my living room floor. I couldn't help but stroke myself back to hardness and slide into my sister as she slid the hard rubber cock into Annie. Annie started to slide her finger in sis' pussy, feeling my cock in her and fingering sis' clit as she stroked my cock.

I whispered in sis' ear, asking her to slide her pussy over Annie's mouth and see if she'd eat her. That also gave me a chance to kiss sis and suck on her up-to- this-point this morning ignored tits. I kissed and sucked on my sister as Annie slid her tongue up sis, tasting doggie cum along with sis' pussy juices.

Realizing what she was tasting, she hesitated at first but sis kept thrusting the dildo into Annie, making her start to cum again, which made me want to be in my cousin for the first time. I traded places with sis, then slid my very hard and now somewhat sore cock into Annie. She was INCREDIBLE!

Her pussy sucked my cock in like it was made for it, and I held my cock against her swollen clit while I thrust into her, shallow then deep... shallow then deep... Annie quietly brought the dog over and decided to do something different... she slowly got the dog hard again and started to suck on its cock. Guess she was saying "thanks for the good fuck" to the dog and the dog responded by bucking into sis's eager mouth.

She slowed doggie down, then brought the tip of his cock to Annie's lips and while kissing Annie and licking the tip, she brought the tip to Annie and slowly guided it in. I'd almost forgotten I was having the time of my life fucking Annie as I watched her slowly, then rapidly suck off the dog. Sis was holding the furry sheath back, so Annie probably thought it was someone else that joined in and they weren't circumcised.

Well... she was sorta right! I slid out of Annie and brought the dog over and guided the tip into Annie while sis put her pussy back over Annie's face...

Wait until part 3...
