“You don’t have to, Darling. She just wants you to know.” Mom said softly, giving me a piercing look that didn’t waver until I nodded.
“Let’s get rid of this.” Mom said, pointing at the condom covering my still engorged cock. The Cialis was doing a fine job, it seemed. Then she leaned into my ear and whispered barely loud enough for me to hear. “Try not to make any sounds until you’re back, Darling.”
I gave her a questioning look, but she waved me along without further explanation.
It must have been a comical display as I basically tiptoed into the adjoining bathroom with my hard rod bobbing in front of me. I got rid of the condom, carefully closed the door to give my dick a quick wash for my own feeling of cleanliness, and then tiptoed back into the room.
Mom placed a finger to her lips to signal me to keep quiet, and she gestured for me to stand next to the bed where Ava lay waiting. However, she had moved Ava so her head was hanging off the side of the mattress. Then Mom grabbed a little notebook from the nightstand and held it in front of me, showing me a handwritten note that said “Surprise nipple pinch”.
Shrugging my shoulders, I reached out and grabbed one of Ava’s pointy and hard nipples between my thumb and index finger and squeezed. Ava’s reaction was intriguing! She gasped, her flat tummy quivered, and she bit her bottom lip.
Wanting to explore this further, I let go of her nipple and took my time deciding what part of her body I should stimulate next. After about twenty seconds, I repeated Mom’s action from earlier and pressed a single finger against the vibrating clit-stimulator in Ava’s panties, causing her to cry out a surprised moan and her knees to shake. Next, after another quiet waiting period, I dragged my nails over her taut stomach, which made her writhe on the bed. Finally, I let the tip of my dick hang about an inch above her mouth.
Mom and I could both see her nose wiggle for a second, before she pensively opened her mouth and slowly craned her neck to explore that smell. She flinched a little when her lips made contact with my cock, but as soon as she realized what it was, she hungrily sucked on it.
Mom stood behind me, her arms wrapped around my midsection with her hands flat on my lower stomach, while nibbling on my earlobe. My eyelids fluttered when the sensation, paired with the feel of her soft pillowy breasts pressed into my back and Ava’s lips around my cock, flooded my senses. Though, I abruptly regained control of my thoughts when Mom started pushing me forward. I resisted, and she pushed with a little more force.
“Not with her hands tied to her back.” I said sternly while looking directly into her eyes and, to my surprise, a proud smile lit up her face.
She let go of my body and walked around me to kneel on the ground next to Ava’s head.
“Do you hear that, Sweetheart?” she said, while one of her hands caressed Ava’s bulging throat. “Your little brother doesn’t want to forcefuck your throat while you’re all tied up. He’s afraid to choke you. Can you believe this? How much he still cares about us, despite everything we did to him, to push back his own desire just to protect you?”
Somehow, that put Ava into the next gear. It almost felt like she wanted to suck the skin of my cock entirely while she moaned in pleasure. Mom, meanwhile, leaned down and placed a kiss on Ava’s throat, leaving yet another perfect imprint of her lips in bright red lipstick behind, before raising off the floor and standing behind me again.
“We already worked that out, Darling.” she whispered. “Her legs are free. She’ll use them to signal us if you need to stop.”
Then she licked my ear, as she, again, wrapped her arms around me. This time, however, she didn’t place her hands flat on my lower stomach, but instead on either side of Ava’s face, before pushing herself against my back again.
“Now fuck your sister’s throat, Baby.” And she pushed her body closer into me, until my hips moved forward. “Use every hole of the slut for your pleasure! But don’t come yet. We have a better place for that delicious cum of yours, although I’m sure she would love it if you were to pump your load into her stomach.”
With that, we heard Ava moan yet again, though it was choked out immediately as I pushed past her tonsils. This, again, was so much better than any experience I had with Ava before, simply because Mom was guiding me through the abuse of my sister’s body. I pushed my cock deep into Ava’s throat, while Mom held her head in place for me, so I could fully concentrate on the feeling without any distractions.
I did, however, keep an eye on Ava’s feet. Mom pushed me forward until my cock was fully engulfed in my sister’s esophagus, and then held me there while gently moving Ava’s head to create friction. Simultaneously, I felt Ava’s throat muscles massage my shaft as she swallowed over and over again. Mom kept me from pulling back way past the time I was comfortable with, because I feared for Ava’s oxygen supply, but it seemed to be okay for her.
I had to smile when I finally noticed how Ava lifted her toes, while the soles of her feet stayed pressed to the mattress, every time Mom pushed me forward until my ball sack would rest on her nose. And every time Ava’s toes would lower themselves again, Mom would back up and allow me to pull my cock out so Ava could breathe.
I had to admit, this was fucking awesome. I couldn’t believe how much planning they must have put into this. Messing with Ava’s birth control, so she could have that fantasy of the ultimate submission back. The matching outfits. The subtle, nonverbal signals they had worked out. The prepared handwritten note that lay readily available on the nightstand. This whole thing was orchestrated from start to finish, for the sole purpose of making this as hot as possible. I didn’t think Mom only came up with all this the day before like she had claimed, and I loved her for it.
“Mom, I’m close again!” I panted after a few minutes, and she reacted by quickly grabbing my hips and pulling me back.
As soon as my cock had vacated Ava’s mouth, it jumped up and smacked against my stomach with a loud wet sound. The cialis was still working, while I got stimulated in various ways, and I noticed that this wasn’t exactly the best thing to do.
Mom must have seen the look on my face, as she addressed it immediately.
“Baby, what is it?” she asked, her voice full of compassion.
“I think the pill, combined with the never ending turn-on, is working a little too well. It’s getting a little uncomfortable.” I admitted, before seeing another sultry smile appear on Mom’s face.
“Oh no! My Baby Boy is hurting!? Mommy absolutely can’t have that!” she cooed before leaning down to Ava. “Sweetheart, your little brother’s beautiful cock is hurting! We have to act fast and make it better, don’t we?”
“Yes, Mommy!” Ava confirmed in a girly voice and nodded her head, taking me by surprise. I had never heard her refer to Mom as ‘Mommy’ while acting like a little girl. Though, I had to admit, it was very effective!
Mom crawled onto the bed to turn Ava around and take off the restrains holding her arms in place. As it turned out, however, she only did so to take off Ava’s bra. As soon as she had unclasped the strap from her bra, she put Ava’s arms into the restraint again and made her lay on her back in the middle of the mattress. Then she leaned over to pull Ava’s panties off and remove the clit-vibrator as well.
She hooked her arms underneath Ava’s knees and made her spread her legs for me. One of her hands slowly moved to the upper side of Ava’s knee, before it just as slowly moved up her thigh, and was finally placed flatly on Ava’s lower stomach, the tips of her fingers pressing onto the skin right above her clitoris.
“So, Baby...” Mom started, as her hand slid further down, over Ava’s clit, and her fingers finally parting her pussy lips to let me look directly into her canal. “ ... does this look like a warm, wet, and snug place to put your hurting cock in?”
