Out of pure fear for what they would do to me this time if I didn’t comply, I nodded shakily and said, “Yes mistress.” But I still couldn’t understand how they thought this to be ethical, and continued, “But this isn’t right. It’s rape, it’s incest, how do you think this is ok? How do you think you’re going to get away with this?”
“We’re already going to get away with this.” Tara said, smugly, “Who are you going to tell, the police? Our parents? Who are they going to believe, two sweet, innocent, pretty young girls, or you? Besides when have our parents ever believed you on such things, or even cared? We’re the golden children they wanted, you were their mistake.”
Tia quickly jumped in to answer my other question, “Either way the rape thing we agreed was quite appealing to us too. It gave the domination and humiliation purpose, and makes it real, which just sounded irresistible to us.” She reached over beside her bed and grabbed something, “Time to shut up now, time to begin.” I soon realised it was a gag she’d reached for, and put it over my mouth as I put in my last few desperate attempts to stop them. There was nothing more I could do to prevent what was coming.
Both girls began tearing my clothes from my body, and left them in a ruined pile on the floor. Tia then moved forward and sat on my stomach, and leaned forward so her breasts were pressing against my chest. I couldn’t help but look down, and I noticed how big they were, they looked bigger than I’d ever seen them before, maybe I had just noticed because of the circumstances? “I’m gonna tell you a secret,” she whispered to me, “One of my fantasies is to be impregnated by my little brother, so that’s what we’re going to try now.”
The thought of fathering my sisters child disgusted me, but my body betrayed me once more as the thought of having sex was enough to get the blood flowing in my penis, as it stiffened up, ready to be put inside my sister. She shifted her way back down my body slowly, until I could feel the tip of my dick press against her underside, which was now so stiff it was pointing directly at it. I then noticed Tia had no panties on under her revealing lingerie, and I noticed how wet she was getting as she got up to start grinding along my shaft.
She lay back down across my body, and got hold of my hardened member and moved it into place, feeling around her genitals for the opening. Once she had found the hole she started to push back against it, my tip reluctant to go in despite how well lubricated she was from her leaking juices, and finally the whole head went in with a ‘pop’. She continued to move down, breasts dragging across my chest as she did, moving my dick further into her tight vagina which felt as if it were unused, getting harder for it to go any further as it went, but she forced it through until my entire 6 inched, thick member was buried deep inside her.
Meanwhile Tara had moved to the back behind us as to get a better view, and just couldn’t help herself at the sight of her little brother being inside her twin sister, and she lay down behind us rubbing her clit, and reached down and massaged my balls and licked between them and our sister’s pussy skilfully. Tia had begun to build momentum, move up and down on my stick, still rubbing her chest on mine, and was encouraged to go faster by her sister eating us behind, and went for faster thrusts which seemed to send me deeper still inside her.
She then reached up and popped her eager breasts out the top of her lingerie to reveal some beautiful, round 34D breasts, with proportionately big brown nipples that stuck out well. This sent me over the edge as I began thrusting into her myself from off the bed, and with one final brutal push deep inside her I began to cum, shooting thick streams of cum straight into her pussy. It lasted for ages, and was easily the best orgasm I’d ever had, and as I finished a hot flush came over me in an afterglow. I could feel myself slowly getting softer inside her, but it still gripped to the outer walls of her tube, before she finally pulled out, not letting a drop of semen spill out, and Tara cleaned off the remains from my tip.
While Tia was still horny from our session together, Tara rolled her sister to the side of me, and grabbed a dildo out of the drawer next to her. It was huge, must have been twice the size of my penis when at it’s best, yet she was able to get it three-quarters of the way inside her pussy, and she violently masturbated her sister with it. Tia couldn’t control herself, and left a gaping mouth with the occasional short scream, and tensed up her body as the orgasm was building. Finally she lay back and pushed her pelvis up, and let out a long, loud scream of pleasure, juices now visibly flowing out of her pussy onto the black dildo, soaking it.
She calmed down from her orgasm what must have been at least a couple of minutes after and Tara removed the penetrative device from her sister, and moved up to passionately kiss her on the lips. They both kissed for ages, pressing closely against one another, occasionally stopping to suckle at each others breasts, with Tara’s now too being revealed from above her skimpy bra, at a size almost as big as her sisters, maybe 34C this time, but visually just as impressive. They would kiss with mouths wide open, passionately moving their tongues around and between them, almost as if they were putting on a show just for me.
Sure enough, the sight of it was enough to get me going again, quite soon after the last endeavour, and they looked over at me with visible pride on their faces at the fact that they had aroused me. They got off of each other and removed what was left of their clothes, and started to crawl along the bed towards me, Tara at my head with Tia below. Tia got between my legs and cowered down, while Tara then straddled over me sitting on the top of my chest, mercilessly tore off my gag and simply said, “My turn.” Tara then got up and turned to face her sister at the foot of the bed, and hovered over my face before lowering herself onto me, and smothered my face between her butt cheeks.
I could barely breathe, with my nose just barely out from under her, but nestled right next to her clenched arse hole. I could only look up and see her glowing blonde hair running down her curved back of smooth, perfectly tanned skin. She looked over her shoulder at me and said, “Come on, lick it bitch!” Not wanting to disobey, I opened my mouth right at her pussy lips, and started to lick up and down her vagina, lips pressed against hers, licking right up to the clit.
Meanwhile Tia had grasped hold of my erect penis once more, and rubbed up and down the shaft, and put her mouth at the end of it and began licking the tip of my penis. She then engulfed it into her mouth, shoved it as far down her throat as she could before gagging, and pulled back a little before settling into a rhythm of thrusting on it and licking around it. She even sought out to get her tongue between the foreskin and the head, and licked it clean. The sensation was wonderful.
By now I had been getting to work on my other sisters pussy, as she excreted moans of pleasure, and even began bobbing up and down on my face as I penetrated her soaking pussy with my tongue, and she massaged her breasts and her erect nipples. Her moans were getting louder as my tongue movement penetrated deeper, and with Tia masterfully sucking my cock down below, it was enough to make me cum again, thrusting into Tia’s mouth as it happened to her shock, shooting jet streams of more thick cum into her mouth, some she swallowed some she left swimming around inside.
She squeezed the remains out and cleaned up, and with a mouthful left she moved up me again and sat on my stomach. She then kissed Tara and shared the remains of my semen with her, the first of my load she’d had in her, and was clearly grateful. It wasn’t long before she was ready herself, her pussy clenching on my tongue as her juices flowed into my mouth and across my face, as she shook in her own orgasm. She collapsed into her sister’s arms, and lovingly kissed her in triumph.
At this point I hadn’t realised it had gotten so dark outside, and had been for a while. The day was over, so maybe my part in this facade was done? Not likely. Tara and Tia both agreed that it was time to go to sleep, as they had a lot more in store for me tomorrow. They left me tied to their beds in fear that I would get away, which is clearly what I would have tried to do. Although, as I began to think to myself, that session wasn’t so bad, and was actually quite enjoyable with two incredible orgasms, but maybe it wasn’t as bad as I had feared, or maybe they were just warming me up to it.
At the end of a long, hard day though, the two girls almost lovingly lay down either side of me, and snuggled up closely to me and cuddled. They quickly went to sleep, and I lay there with them laying on either side of my chest with their respective breasts firmly pressed against my ribs, clutching around my arms and wrapping around one of my legs each with both of theirs. We lay their in an afterglow, feeling a strange sort of affection for my sisters, even through all they’d put me through. But instead of basking in the afterglow of it, all that was on my mind was what they could possibly have in store for me tomorrow.
