Hey there, everyone. Joseph Cuomo writing again. If you remember, my last tale finished when I exited my sister Kailey’s room after fucking her and my girlfriend Harper all night. As I walked out, I bumped into my mother. Because it was blatantly obvious what I’d been doing, I baldly told her the truth—that I’d been having consensual sex with her daughter/my sister, and my girlfriend simultaneously.
To my shock, and after considering it, excitement, instead of taking me to task and being horrified, Mum stepped in close and took my balls in her hand before kissing my mouth and saying, “Come and see me after your dad’s gone to golf, Joseph. I need fucking, too.” Then, she let my balls go and swiftly walked down the hall to her bedroom.
I looked at my mum’s tennis-toned ass in her short silk nightie and thought, “Well, why not?”
I stepped back inside Kailey’s bedroom excitedly to tell the girls what Mum had said. Harper was immediately keen to join the debauchery, but Kailey was more reticent. Eventually, Kailey agreed we should wait for Dad to leave for golf, then approach Mum and see how she reacted. For the sake of our budding relationship, we decided that it was all or none of us. If Mum wanted solely me or just Harper and me, then it was none of us unless Harper wanted to play with Mum alone, and Mum was agreeable.
I returned to my bedroom to ensure Dad wouldn’t discover I was naked in my sister’s room, but sleep was beyond me. My thoughts swirled all over the place. I’d never thought of my mother, Lana, in a carnal way before. But now? It was all I could think of. Mum had us pretty early. She was only twenty when she gave birth to my sister, and I came along four years after that, so she’s only forty-six now. And she’s aged well, you know? Mum was a cheerleader at high school and college until she married Dad and got pregnant, so her body is still pretty bangin’, too.
I waited until I heard Mum clattering around in the kitchen before leaving my room to join her. She looked at me nervously before blushing and shrugging. I winked and shrugged, too, and then we continued as if the words between us hadn’t been spoken. Dad came in shortly after that, scarfed some toast and coffee, mumbled about being late for his tee time, and left.
Kailey and Harper entered the kitchen not long after Dad had left. They wore matching babydoll nighties that left little to the imagination. Their firm 34B breasts strained against their tops’ bodices, their belly buttons were sexily exposed, and both girls had sweet, prominent cameltoes. Their hair was messy, and to a knowledgeable observer, it was apparent they’d been doing more than sleeping.
Taking it in her stride like she always did, nothing too much bothered my mum. She cheerily said, “Oh, hello, Harper. I didn’t know you’d stopped here for the night.”
My girlfriend replied, “Yeah, I was a little under the influence at the party Kailey and I went to and had lost my friends. Rather than leave me there alone, Kailey made me come home with her. I was supposed to be out for the night anyway, so Mum and Dad won’t have missed me yet.”
“That was nice of you, Kailey,” Mum said evenly. She knew it was a lie but wasn’t concerned about that, only that Harper and Kailey were safe and home.
Harper grinned, knowing she’d been caught out, but my mum wouldn’t call her on it. She asked if Mum needed any help with getting breakfast, and they started making waffles, eggs, and bacon together.
While their backs were turned, Kailey quickly grabbed my neck, and we shared a brief but intense kiss. She whispered, “Harper’s going to sneak out again tonight, so come to my room when she gets here, okay?”
“Sure,” I agreed, momentarily pushing my swelling, mushroom-headed cock against her belly. We parted before Mum caught us.
Kailey and I sat on opposite ends of the table and ignored each other as we typically did. It was very much like plugging the barrel’s hole after the water had leaked out because I’d already confessed our incestuous relationship to our mother, but it was good practice for when our father was home. Having Mum aware we made love together when she’d hinted that she wanted to do the same was one thing. Having Dad find out was something else entirely. I don’t know how he’d react if he discovered the rest of his family fucked each other, but I couldn’t imagine it would be positively.
Harper carried my plate to the table when it was ready and sat beside me. Mum did the same with my sister. We ate, joking with and teasing each other as families do, and then I helped Mum clean up while the girls showered and changed. She remained silent as we worked together, but her face was red with embarrassment, and she was pretty nervous.
“Relax, Mum,” I said. “If you’ve changed your mind, then that’s okay. I won’t hold what you said against you or tell anyone what you offered. So, take a chill pill, will you?”
Mum looked around fearfully to ensure we were alone. “Incest is wrong,” she hissed quietly. “I know that. But the thought of you and Kailey making love is just so exciting. I wanted my big brother to fuck me, but I couldn’t make it happen no matter how often I flirted. Knowing you and your sister are intimate has me hotter than I’ve been since those days, but I’m too scared to do anything about it because ... well ... incest is wrong,” she added, returning to her earlier sentiment.
I mimicked her fearful look around despite knowing Kailey and Harper would see what we were doing and give us space. Then, I grabbed her shoulders and softly kissed her lips. Mum shuddered before she arched back, pressing her lithe body against mine. Her hands came up, and she held my head as she deepened our kiss. I let my tongue explore her mouth as hers battled with mine.
I wanted to slide my hands down her upper arms and kiss her more passionately as I strummed her erect nipples with my thumbs, but I suspected doing that would overwhelm her, and she’d pull away. So, instead, I let our kiss linger until she pulled away. Eventually, Mum pulled back and turned away, covering her longing and arousal.
“Let me think about it, please.”
“Sure,” I agreed, winking at Harper and Kailey as they peered around the hallway door, waiting for it to be safe to enter and say goodbye to Lana.
I grabbed a cup of coffee and sat back at the table. Then, after I’d sat, Kailey and Harper entered the kitchen.
“See you next time, Mrs Cuomo,” Harper said breezily, hugging my mum and ignoring her tented nipples.
“I’ll drop Harper home and then meet my study group at college,” Kailey said, kissing our mum on the cheek and also ignoring how erect Mum’s nipples were. “I’m going to a birthday party after that, but I’ll be home around midnight.”
After they left, Mum poured herself a cup and joined me at the table. For the sake of losing the awkwardness between us, I spoke of my upcoming races and how my training for my first marathon was going. However, it was clear that she couldn’t be diverted from her thoughts about whether to consummate her offer to me.
“Ask your questions, Mum,” I said, knowing it was the only way forward.
“Was last night the first time you and Kailey made love?”
I sighed. “No, Mum. It was the second. The first time was nearly a year ago. After that time, Kailey and I tried to deny what we felt for each other, but we were fighting a losing war. Last night, we lost that battle and consummated our desire for each other.”
“So, making love together is a new thing, and you haven’t done so very often?”
“That’s right, Mum.”
“Why did you invite Harper?”
“I didn’t,” I said truthfully, although that wasn’t the whole truth. I certainly wasn’t going to admit that I planned to drug my sister and then rape her with my girlfriend helping. “I didn’t know it, but Harper and Kailey were lovers before Harper and I were, although Harper and I were dating before she and Kailey became lovers.”
“Harper and Kailey are lesbians?”
“Hardly, Mum,” I laughed. “They’re bisexual, I guess. But they both prefer men.”
Shocking me with her honesty, Mum said, “I’ve never been with a woman, but I’ve often fantasised about what it would be like. Do you think that if I decide to succumb to my desire to taste the forbidden fruit of incestuous love, Harper would join us?”
“She probably would,” I said carefully. “She wishes that she had a brother she could seduce, and she makes love to me and Kailey simultaneously, so she’s not averse to incest. I guess that means she’d be okay about joining us, assuming she finds you attractive.” I waited to see if Mum would respond, and when she didn’t, I added, “There is a problem, though. I don’t think Harper would join us unless Kailey does, too.”
Now, I’m still fairly innocent when it comes to reading signals. After all, I had no idea that my sister wanted to continue our incestuous affair, but she wanted me to take the lead and initiate our lovemaking. Nor did I have any idea that my girlfriend and sister were lovers. However, even I knew what it meant when a woman bit her bottom lip, her eyes dilated, and her nipples tented her top. Although her society-programmed mind immediately told her she was wrong to want that, Mum’s subconscious, where all the nastiness that our social conditioning prevents from appearing lurks, found the idea of bedding both her children and Harper simultaneously titillatingly erotic. I just had to find the key that would unlock her subconscious desires.
I thought Mum would take the leap and say ‘yes’. However, she only said, “Let me think about it, okay?”
“Sure,” I replied. “No pressure from me. In fact, I won’t even mention it again unless you do.”
However, before returning to my room to change and go for a run, I pulled Mum out of her chair and kissed her with all the skill I had. Only this time, I did let my hands slide down to her upper arms, and I did strum her nipples with my thumbs. Initially, Mum froze, and she was stiff in my arms. But when my thumbs circled her nipples, she moaned into my mouth and pushed her hot pussy against my balls.
I released her and smiled warmly down at her. “I love you, Mum,” I said. “I’ll love you whatever you choose to do. So, talk to me when you’re ready, okay?”
“Sure, Joseph,” Mum said breathlessly when I released her. Her legs gave out, and she sank back onto her chair, unawarely touching her lips and gazing wonderingly at me.
I smiled again and went to my room to change. When I returned, Mum had gone to tennis. I showered and then lay on my sister’s bed, remembering the previous night and fantasising about what it would be like to have Mum join us. After cumming into a tissue twice, I went to my room to catch up on the study I needed to do for college. The rest of the day passed uneventfully.
Mum returned first, and she smiled guiltily as she kissed my cheek and went to her en suite to shower. I considered sneaking down there to watch her but thought better of it. Dad would be home soon, and Mum might react negatively and think I was trying to pressure her to have sex with me.
I was glad I didn’t because I’d barely opened Call of War: World War II and joined my crew when Dad came home. My door was open, so he stuck his head in to say ‘hello’. I acknowledged him with my typical grunt and continued communicating with my team as we set up our next attack.
Mum cooked dinner, and I hung out with the oldies until around 10:00 p.m. After they’d gone to bed, I opened my computer and fiddled around with various things until midnight. I grinned when Harper and Kailey came into my room together. They took my hand and dragged me to Kailey’s room. She had a queen-sized bed to my king single, which made more sense to use than mine. Also, Kailey’s room was lockable, and mine was not, so there was less chance that one of our parents would come in and catch us fucking.
I stripped as soon as I shut Kailey’s door, and the girls dropped to their knees before me. As I’ve described, my cock isn’t particularly long, being only four inches, but it’s built like a bath plug. For those of you fortunate enough to have one like mine, you know what I mean. With a cock shaped like mine, its width means it pushes against the woman’s G-spot immediately you’re in through their entrance. While it’s true that some women enjoy a cock that raps against their cervix, most find that painful. So, boys, instead of trying to knock your girlfriend’s uterus out her mouth, whisk your cock around inside her by stirring your hips and ensure your dick swirls over your lover’s G-spot. I guarantee you’ll both be much happier!
With my cock’s head being so broad, it was easy and delightful for me for the girls to place their lips on either side of it and lavish it with their tongues. Kailey would lick across one side of it, heading towards my shaft’s base, while Harper would run her wet lips in the opposite direction, pausing to dab her tongue into my dripping cock’s eye. Then, when my girls reached their destinations, they’d reverse direction and continue licking and sucking.
I couldn’t and didn’t last long with Kailey and Harper providing such delightful stimulation with their mouths. Also, having my sister and my girlfriend, who could seriously have been Kailey’s twin, looking appealing me up at me as they serviced my cock willingly was visually appealing to the point of me not needing much more than them watching me adoringly to achieve my climax. My girls pressed their cheeks together and let my cum splash over their faces. Then, they turned to face each other and used their lips and tongues to clean my semen from the other’s face.
Of course, watching them do that for each other meant my erection hardly faded at all, and I was soon throbbingly stiff again. Kailey then crawled across to her bed and lay her upper body on it. Harper avariciously watched Kailey’s seductively swaying ass crawling across the room before following her. I was treated to two tight, muscular cheerleader asses swaying before me, and the result was a raging wave of desire blasting through me.
Grabbing my dick, I raced across the room, ready to shove it in one of them, but Harper slapped my arm. “Wait, Joey. I’ll get her ready for you. Be patient, you oaf.”
I thought I’d get to fuck my sister’s pussy, but Harper went to town on Kailey’s ass instead. Harper let her spittle drip onto Kailey’s tailbone and slide onto her pucker. Then, she reached around Kailey’s muscular thigh and used her first and third fingers to part Kailey’s pussy lips. With her middle finger, Harper stimulated Kailey’s nubbin as she eased the index finger of her other hand into my sister’s ass. A second finger quickly followed the first and a third shortly after that. Before long, Harper had Kailey’s asshole gaped enough to take my mushroom-headed cock.
