Stepsisters
By fist1951
I had been living Cynthia, an attractive, 46 year old woman, for about a year when her 42 year old step-sister, Heather, moved in with us. Heather was a real good looker too, at 5'4” 118 pounds with really firm 32B breasts. Heather moved in after breaking up with an abusive boyfriend she had been living with. She and Cynthia were pretty close for step-sisters. Cynthia's father had married Heather's mom when Cynthia was 20 and Heather was 16.
The first time I saw Heather was at party for Cynthia's dad. It was a pool party, and the stepsisters were wearing very skimpy bikinis. Even at 41 and 45, both women were really hot in that attire. In fact there were some younger women at the party that got rather upset their husbands were eyeing the two. Cynthia noticed me casting more than an occasional glance at Heather and playfully teased me about it. In fact the “teasing” became a regular part of our sex life after that. Cynthia would taunt me saying things like, “bet you'd like to see Heather's tits wouldn't you?” She even occasionally made references to what it might be like to have Heather in bed with us, well that would usually result in me popping my rocks right there!
Naturally when Heather moved in with us, I started having visions of threesomes dancing in my head. Cynthia put a screeching halt to that notion when she pointedly reminded me THAT (the earlier teasing) was pure fantasy and for me not to even think about it. She made it clear to me her stepsister was strictly off limits. I believe she also had a similar discussion with Heather, telling her I was off limits. The only thing was we (Heather and I) were attracted to each other. I got a sense of it one night at dinner, catching more than one or two glances from Heather. Cynthia caught it too and responded with an icy look at her stepsister that for the moment squelched the visual flirting.
Up to that point, whenever Heather went into or came out of the shower she would be completely wrapped in a huge bathrobe. Then she began appearing wrapped in only a towel, and the towels kept getting smaller. There were other things she never missed a chance to walk past me in a manner which would enable her to brush against me. Cynthia picked up on some of these things as well, filling in the blanks with her imagination. I came home one afternoon to find the two of them in a screaming match. Apparently the argument started over some trivial thing, but fueled by the growing rivalry, the minor disagreement quickly escalated into a loud verbal argument. They were facing each other, almost nose to nose. I think had I not walked in at that moment, the argument would have escalated further into a physical altercation. When I came in they both cooled down and things seemed to settle down between them, it was almost as if the shouting match was a safety valve that let them blow off steam.
I had pretty much given up on my fantasy to partake of Heather's womanly virtues, even though the quick, flirting glances continued, though more subtly. One afternoon I came home almost three hours earlier than normal and Cynthia was still at work for another four hours. Unknown to me, it was Heather's day off and she was lounging on the family room sofa reading when I came in. The short cut-offs and skimpy halter top left nothing to my imagination. She smiled and said “Hi”, commenting on the fact I was home early. I chatted with her a bit then said I was going to take a shower and work on some files from the office.
What I really needed was a COLD shower at that point. I quickly went to the bedroom, stripped and got in the shower off of the master bedroom. Even though Cynthia and I had an incredibly wild lovemaking session that morning, I had a throbbing erection. The water was running nice and hot and the bathroom quickly steamed up as I tried to put my thoughts on anything other than Heather. I was in sort or a stupor letting the hot water cascade over me and did not hear the bathroom door open. I did hear the shower curtain open though and there was Heather, standing in front of me completely nude. Glancing down at my erect penis, she said, “Gee, were you expecting someone?” Wordlessly she stepped into the shower and we locked in an embrace, our lips and tongues hungrily devouring each other. Feeling her gorgeous tits against me, with her nipples hard and erect nearly made me explode.
We quickly emerged from the shower and got in bed. She was all over me, almost immediately mounting me. I said, “Cynthia might come home.” Heather said, “She won't be home for another few hours, and besides I'm not worried about her, I whipped her ass once in a fight when we were in our 20's and I can whip it again if I have to.” Well, that was news to me. I told Heather Cynthia never told me about that even though she knew I was a huge girl fight fan. Heather wasn't surprised Cynthia had never mentioned it. “Beat her ass bad then humiliated her in front of two of her girlfriends.” When I asked how she humiliated her, Heather just smiled at me and in an instant was sitting on my face practically smothering me with her hot, wet pussy. That story got me going and in no time my throbbing manhood was buried in her love nest. We both had explosive orgasms and were almost tempted to fall asleep. Heather kissed me then went off to her room. I got back in the shower and removed all traces of my encounter. Fortunately we had a towel on the bed, so I did not have to change the sheets.
Cynthia came home a few hours later and later that night jumped my bones. Amazingly I was able to get it up. Maybe a threesome was out of the question, but this was pretty dang close! After that, it seemed Heather thrived on seeing how close we could sneak around. She started stealing quick kisses and having us grope each other when Cynthia was in the house. On several occasions when Cynthia would be in the shower, Heather would come over to me, open her robe and sit on my lap.
Then we really started pushing the limits. Some nights I would have sex with Cynthia, after which she would go sound asleep. I then tiptoed into Heather's room next door. She would already be worked up having masturbated while Cynthia and I were going at it. One night was a close call. After another “double header” I went back to our room and got back in bed. Cynthia woke up a few minutes later sometime in the middle of the night. She was hot to trot again and started kissing and groping me. She grabbed my cock and feeling the wetness said, “Ohhh baby, you're still wet from earlier.” She pulled me on top of her thrusting her hips up until my now hardened cock slipped inside her vagina. These little dalliances carried on for several weeks, I thought I'd died and gone to heaven! We had numerous “close calls” and that only heightened the excitement.
The one evening I was sitting in the family room lounge chair wearing only a robe. Cynthia had just gotten in the shower when Heather appeared, also wearing only a robe. I discovered that last detail as she walked over to me and let her robe open. It was to be another one of our little quick “teasers” a fast grope, some stolen kisses. The only thing was this was the first time we were both practically nude. Normally during these encounters we would both be fully clothed. This time it started that way but she was like a dog in heat, and I wasn't exactly resisting. Heather expertly opened both our robes and straddled me on the chair. Without any effort at all my shaft slid smoothly into her soaking wet pussy.
Needless to say, we both sort of lost track of time. I don't know how long Cynthia stood at the door, but the next thing I knew, I heard Heather yelp in pain and felt her pulled back violently off of me leaving my cock swinging in the breeze like a door. Her hair was bunched up in Cynthia's right hand pulling her head back. Cynthia didn't say a word. She just started raining blows from her left fist into Heather's face and breasts. I made a feeble attempt to separate them, but Cynthia snarled at me. “You always wanted to see a catfight, so shut up, get the fuck out of the way. Either watch or get the fuck out but don't even think about interrupting.
I was concerned they would really hurt each other. Heather's nose was already bloodied. Cynthia pushed her to the floor, then standing over her took off her robe and put her fists up in a fighter's stance challenging Heather to stand up and fight. Heather scrambled to her feet taking her robe off also. As soon as she was nude, Cynthia rushed her and they tumbled to the floor. Heather grabbed a handful of Cynthia's hair and yanking her head back, drove her fist hard into Cynthia's mouth splitting her lip against her teeth. Before Cynthia could retaliate, Heather followed up with straight right jab into her nose instantly bloodying it. Both women were now bloodied and the fight was only seconds old. Blood was running down Cynthia's chin from the busted lip and her nose.
