Ro3: Submission

As she gasped in pain and ecstasy, Joan tried to figure out just where it had all gone wrong.

After leaving her sister to deal with Suzanne she had tiptoed ever so quietly up the stairs, frowning slightly when she padded through a damp portion of carpet. Joan had decided to do a touch of reconnaissance before calling out her sister and her busty friend. She pressed an ear against her sister's door.

“-Two Pump Chump?” Joan made out her sister's voice on the other side, accompanied by some heavy panting. “Couldn’t satisfy her at all with that little thing. Can’t even stay hard…” Then a girlish squeal, followed by her sister chuckling lightly.

Joan backed up to the other side of the hall. Stay hard? Panting? Screaming? It couldn't be. Her incredulity only slowed the gears in her mind as they lurched into place. Did that make Robin a shemale? She certainly didn't look the part, her face was astonishingly feminine and her bust was larger than her mother's had been when she'd been nursing the twins. The two mouths sucking on that perfect rack, slurping out every last drop of sweet succulent—okay, that was weird! Joan caught herself thinking about her mother in a way no daughter had any right to. It was probably just because of what had happened with her sister combined with Shannon's theory about what Sharon and Suzanne had been up to. Or at least she hoped that was the reason. Or maybe it was a gas leak.

“What? Some kind of aphrodisiac is leaking from our gas vein?” Joan muttered to herself. A gas leak was highly unlikely or she would have been affected long before Robin, after all she'd been in the house all day. Maybe she was on to something with the aphrodisiac theory, if Robin had brought something in the house with her. Although she had never heard of an aphrodisiac living up to its reputation this still seemed like the most plausible explanation.

Having sufficiently regained herself Joan crossed the hall again to do a touch more eavesdropping... Only to fall straight into Sharon's room after her sister opened the door at the most inopportune moment.

Sharon immediately sprang into action and shut the door behind her before shouting, “What the hell were you doing!?”

Joan found herself blushing, she was caught red handed. “Nothing... Well, nothing untoward anyway. I was just about to call you down because Shannon's here, and I heard some weird noises coming from your room so I--”

Now it was Sharon's turn to turn red, although whether from embarrassment or anger it was anyone's guess. “So you decided to spy on me!?”

“This is your sister, right? Does she have one too?” Robin asked, eyeing Joan up and down, clearly undressing her with her eyes.

Robin spoke up from her sitting position on the bed. “What does she mean by--”

“Shut up Robin,” Sharon hardly missed a beat in cutting off her friend.

“It must be really hard to, like, hide it under those jeans...” The cheerleader continued to muse.

“I said, shut up.”

Robin gave no indication she was about to silence herself. “Naw, she can't have one under there. So that makes her your... Your what? Shy submissive sister?”

That's when the most bizarre thing happened. A green light pulsed from Robin's finger. Joan felt an unnatural shudder spread through her body, and she squinted to get a better view of the ring. No luck, she would need to actually get up and walk over to her to see what was on her finger, but there was no way she could approach somebody she was meeting for the first time like that. She was far too shy. Even meeting Robin under these bizarre circumstances was bad enough.

“Submissive? Oh, how I wish that she were. I'd have taken care of her long ago and she'd be...” Sharon practically leered at her, “Bulging by now.”

Joan saw the front part of Robin's skirt rise up at her sister's words, but she looked away bashfully before Robin could free herself and respond, “You'd do that to your own sister, with, with your... Your thing?” 

“L... Look.. I'm... I'm really sorry... So sorry... I shouldn't have... I'll just go...” Joan stammered out nervously, she stood up and held out her hand to the door.

“No, stop!” Sharon cried, and Joan found herself powerless to reach any further. Her sister had spoken with such **** she couldn't do otherwise. Sharon turned to Robin, “if she tells anyone what she's heard it's game over.”

“I won't tell... I won't tell anyone...”

“There's only one way to be sure of that. Back away from the door.”

Joan couldn't help but comply, retreating to the far side of the room. Sharon walked up to her door and locked it tight, then turned to face her with a look she'd never seen in her eyes before. Sharon unzipped her dress, and Joan felt her eyes go wide as she beheld the reason her sister had always been so secretive about her body. There was an enormous fully erect black penis straining against the material of her sister's pantyhose. What's more it didn't look like a strap-on... It looked like... Well, like a horse cock. Joan closed her eyes and apologized for peeking, even though it seemed like her sister had meant to do this.

“Can I do this one, Share-bear?” Robin asked, “I mean, you got to do Suzanne and--”

“And risk you knocking her up!? Not even if hell were to freeze over.”

“Well, then can I have her mouth?”

Joan couldn't believe what she was hearing, yet she couldn't bring herself to move. Just like when her boyfriend had **** her to blow the entire football team she never knew how to get herself out of bizarre sexual situations, she just couldn't say no.

“That's my sister you're talking about,” Sharon muttered as she ripped a hole in the front of her pantyhose and began approaching Joan. The bouncing of that penis was almost hypnotic.

“I'm sure she doesn't mind.” Robin moved onto her knees on the bed and waved her dick in Joan's direction. “Hey, girl! Come over here and suck me off!”

Joan's heart pounded, she didn't know what to do. Just like her boyfriend Robin's voice had a power over her that she couldn't control. Joan crawled onto the bed to meet her and looked at what she was packing. This confirmed it, Robin was a shemale. She supposed she should have felt more intimidated by the size of Robin's cock, but after seeing Sharon's this one didn't seem quite as sizable. Timidly Joan placed her finger tips on Robin's shaft and licked a drop of precum from the tip. Her face flushed as Robin moaned above her and bit down on her lips. Joan took a deep breath and leaned forward, taking as much of the organ as she could.

“Try to last a bit longer this time, or--” Sharon may as well have not been talking. Joan suddenly felt Robin's hands on the back of her head, driving her face straight into Robin's crotch. Joan gagged while Robin squealed like a swine in the throes of ecstasy, pumping her fluids directly down Joan's quivering gullet. “Jeeze Robin, Mom was right. You really are a two pump chump.”

Sharon joined the pair on the bed and lined up the flared head of her cyclopean cock against Joan's cunny. Joan was fairly dry so Sharon rubbed the tip around her crotch until precum began flowing freely from the end, as if Sharon had turned on a faucet. Robin's grip slackened on Joan's head, and her semi-flaccid stick slid out of her mouth. Joan saw her opportunity and began to stand.

“Don't move. You are mine and you will not leave this room until your pussy is gushing with my horse seed. You're my mare now understand, as such that precious little valley between your legs belongs to me, from these quivering lips...” Sharon nestled herself against Joan's labia, “to this tight little passage...” She used her hands to push the first inch of her cock inside of Joan. She cried out in pain as her sister's dick filled her more widely than she'd ever been filled, she felt beyond capacity, but she couldn't bring herself to pull away. “To your gaping cervix!” Sharon thrust her hips and hands forward simultaneously, completely filling out Joan's passage. She felt as though she might pass out from the pain, or was it pleasure now? She had no idea, all she could tell was that being treated like this was somehow making her feel... Good. She was Sharon's submissive mare, and she was loving it! “To... To your fucking womb!” Another push and she was beyond the cervix, Joan yowled uncontrollably. It felt as though lightning was shooting across her body from her crotch, it was electric in every sense. “And everything beyond!” Sharon started emptying inside of her, as if she was somehow able to release her seed at the exact moment she pleased. Joan was her sister's little slut now, her **** to use bruise and **** as she saw fit.

“That's hot.” Robin said, again fully erect. She guided her own comparatively tiny member into Joan's mouth, and she took it wordlessly. Sharon asked her if she was ready to give her mare a real fucking, and Robin nodded, a look of intense concentration on her face, clearly willing herself to last longer than her last pathetic attempt at sexual activity. Simultaneously the two shemales pulled back and thrust forward into Joan's willing body...
