Once Stephanie had made Cass cum, she was eager to join in with the fun. Stephanie sat up on the couch next to me, cuddling into my other side, as Cass took a few minutes to recover from her orgasm before she replaced Georgie in the arse of my sister. Jane’s mouth was now free and she was being very complimentary to Alexa, who’d already cum in her but had barely gone soft.
For the next couple of hours, my sister and ex-wife were fucked solidly. Cindy and I couldn’t watch without being completely turned on, so she ended up riding me slowly on the couch. When Stephanie asked for a turn, we had to make sure I’d wiped off my cock first before she straddled my lap. She joked that it wasn’t that time of the month to try again, but she happily slid down my cock, enjoying the warmth of her pussy. As always, the two sister’s made out while Stephanie slowly rode me.
“Want to ride your sister?” I whispered into her ear. She moaned softly, her head resting on my shoulder. “Want to feel her thick girlcock inside you?”
I always teased her because she admitted to having some desires, but like my sister and myself, we’d never cross that boundary. Not sober, anyway. “I’d love to feel her inside me,” Stephanie whispered back, “But I do prefer your cock, Mark. You always feel wonderful inside me. I haven’t had such great sex in years.”
“Told you so,” Cindy whispered, “Our baby will be made with love, Steph.”
“Hopefully I’ll be pregnant soon. To give you the gift of a child, Cindy…”
Stephanie enjoyed an orgasm rather quickly, wrapping her arms tightly around me once it passed, before she resumed riding me. Lifting her up, Cindy moved to the edge of the couch, resting Stephanie so her head rested back on her lap, spreading her legs as I slid back inside her. As I resumed thrusting into her, Cindy’s cock was dangerously close to her sister’s face, and Stephanie realised that too.
“Going to cum soon?” Cindy wondered, “As I’m getting horny here, Mark.”
“Want me to make love to you again?”
“Once you’ve cum in my sister.”
Stephanie loved it when I did finally cum inside her. She knew her cycles and was fairly sure she wasn’t fertile. Cindy made me chuckle, stating her sister should come around to be filled every day except for those few days when it would be impossible for her to fall pregnant. While I chuckled, I knew how much Cindy wanted a baby. But so did Stephanie, so there was no pressure. The three of us knew it would happen eventually.
The lounge was wide enough that Cindy could lie back, giving me a few minutes to recover, before I could slide inside her next, Stephanie lying on her side next to her sister as she watched us make love. Jane, Megan and all the others were still enjoying themselves from the sounds of it, though I was barely paying attention to them now, my eyes only for Cindy and her sister.
No idea how long Cindy and I made love for, but by the time I did cum inside her, and she’d cum all over herself after fucking her nice and hard until she did enjoy another orgasm, I realised things had gone a little quiet. To my amusement, when Cindy had cum, a bit of it had landed on Stephanie, who simply didn’t know what to do with it. Cindy eventually grabbed her arm and licked it off.
Sitting back with a drink in hand, I noticed Jane was now lying back on the floor, looking rosy cheeked and rather satisfied with life. Getting up and lying down next to her, resting on my side, she turned her head to look at me. “Wow,” she whispered, “Holy shit, wow, Mark.”
“Enjoy yourself?”
“I’ve had a wonderful night. I love your friends.”
“Oh, we love you too,” Alexa stated, “I can now tell people I’ve fucked a brother and sister.”
Megan was also exhausted, crawling across the floor and practically smothering me with her body, lifting her head enough to thank me for introducing me to all her friends too. “I can feel their cum leaking out of me,” she whispered, “Want to eat my pussy?”
“I will,” Jane stated, “Straddle my face and I’ll clean you up.”
Watching my ex-wife straddle the face of my little sister, who quite happily licked her almost clean over the next few minutes, was far more erotic than I’d care to admit. What I didn’t expect was for Stephanie to crawl across the floor and do the same to my sister. “Holy shit,” Cindy whispered, “This is totally fucking hot, right?”
“Free lesbian show!” Cass exclaimed, “We don’t get many of them in our club. Too many gay guys and transmen or transwomen for their liking.”
Jane ate Megan out to an orgasm, my ex-wife falling onto the floor as her body was jelly. Stephanie ate Jane out until my sister enjoyed another orgasm, sitting up enough to drag Stephanie up onto her so they could enjoy a kiss and a cuddle. Looking around the room, most of the girls were now looking a little tired. No real surprise as we’d been in that room for a few hours by then, checking the time to see it was well after midnight.
Agreeing to start cleaning up and ready to leave, Jane wanted a cuddle with her brother once we were dressed. Stroking the back of her head, she gave me a squeeze, thanking me again for a great night. I told her that seeing her express herself how she wanted was what made me smile. The fact it was a sibling I was watching have sex didn’t cross my mind, and she felt the same way in regards to myself.
Having organised transport home, we all agreed to return to Alexa’s home. We couldn’t go to our apartment, simply too small for the group of people, while the kids were at Megan’s place, and though it was unlikely we’d continue fooling around, Alexa’s home was probably the safest. Cindy snuggled into me on the way home and fell asleep, Stephanie doing the same thing to my other side. I noticed Jane fall asleep next to Alexa, and I wasn’t the only one to notice my lover took a real shine to my little sister. I knew Cass also really liked her, wondering if my sister might end up experiencing a new sort of relationship if she was willing to give it a try. Megan couldn’t stop smiling as she cuddled into Caroline, and I know Caroline absolutely loved experiencing all these things were her girlfriend.
Everyone had their second wind by the time we arrived at Alexa’s place. It was a lovely three-bedroom house. It was a rental, not her own house, but she’d been allowed to decorate a bit, and had certainly given it a homely feel. After ensuring everyone had a drink in hand, we gathered in living room, the evenings now too cool to spend outdoors unless we were wrapped up.
Jane sat on my lap as I took a seat in one of the available armchairs, sitting sideways so she could rest her head against my shoulder. Her dress had ridden up so high I could see all the way to the thin fabric of her thong, her legs looking spectacular in her thigh high stockings. She noticed me looking and smiled. “You approve, big brother?” she breathed.
“My little sister does have a nice pair of legs. I can appreciate that much.”
“What about the rest of my body?”
“Jane, trust me, you’re fucking gorgeous. Will is an absolute fucking idiot. He chose a girl over a woman.”
She kissed my cheek. “You always know what to say to make me feel better,” she whispered, “Couldn’t have asked for a better brother.”
“How are you feeling about tonight?”
“Wonderful, Mark. I had a great time.” She looked around the room. “You’re all beautiful women and I’m so glad you’ve accepted me into your little group for tonight.”
“Consider yourself invited whenever you can make it,” Alexa stated, everyone in the room agreeing. Then she smirked. “And if you ever find yourselves fucking each other, I’m not the only one who’d want to watch. The ultimate taboo.”
I couldn’t help chuckle as Jane turned her head, burrowing into my chest. “Is it that obvious?” I had to ask.
“It’s not just obvious, Mark. She pretty much told all of us about the crush she used to have, and the fact she sometimes wishes you weren’t siblings.”
“We could fuck each other if we were cousins,” Jane whispered, “Though I’d still not do anything to affect your relationship with Cindy.”
