Adrianne headed up the stairs extremely giddy with excitement. She couldn’t tell what had come over, but it was so hot. She tried masturbating in her room, but it wasn’t the same. She had forgotten to grab her vibrator from her room. When Sylvia and Erick came over, they slept in her bedroom downstairs, and she took the guest bedroom upstairs.
She sighed. She wanted to go downstairs and grab the vibrator, but what if Erick and Sylvia were in there? She couldn’t embarrass herself like that. And what about Erick? She thought, “I mean, he didn’t protest and was really into it,” but she definitely crossed a line with her own sister’s man! There is no way. As an outsider, she thought Erick and Sylvia seemed happy and fulfilled. What had pushed her to do something so risky and wrong?
As she recalled the events. The nice fat cock hard and warm in her hand throbbing as she brought her face closer and closer to it. Her lips and tongue barely making contact before she was rudely interrupted. Fuck. She didn’t want to think about what would’ve happened had they not been interrupted. Although under the cover, the explosion of hot cum had her so wet. She breathed in her hand were the cum had been. Her deep dark desire new that in that instant before getting interrupted, she ached to have that fat cock shoved into her mouth and rammed down her throat. She had never been a fan of giving head, but she blushed, thinking about the sensation. She hated gagging on her ex-boyfriend’s cock. Still, she had never been this turned on. She fantasized how being so overwhelmingly turned on now she would kinda enjoy the gross sensation of it.
Fuck, she needed that vibrator. She heard the downstairs shower cutting on. Fuck it, she was going to retrieve it. She made her way downstairs and slowly checked in the bedroom; there was no in there. She checked the main den area to find her sister snoring. “Sorry, sis,” she thought, “your little sister chose the wrong time to be a hoe.”
She found her vibrator, but as she pushed the button, it was dead. She scrambled to her backup, one that was too big for her tight pussy but still felt good on her clit, and that shit was dead too! Wtf!!!
As she was searching for her charger, she began to think. “I always leave these ready to go; they have great battery life!” She kept searching as a thought crept into her mind. “Did my sister use my own vibrator? Why!? That’s gross!” she thought while secretly feeling immensely turned on at the thought of her sister using her vibrator. “I really need to cut on the light I can’t find shit!” She said as she sniffed one and licked it. She always did an excellent job of cleaning and drying hers after each use, but this time she tasted something sweet and slightly sour. “Oh, fuck.” She sighed as she felt her panties getting soaked. “No way she’s got a man. Why would she be trying to get her rocks off with this?” Without realizing it, she was now licking every inch of that dildo, getting every spot of that sweet, strange, slightly sour taste.
She hadn’t noticed the water cut off. She was sitting on the bed now sucking on the dildo, thinking about how she would charge them both and suck on one while ramming the other one into her now flooded pussy. She fantasized about one those dildo’s being Ericks. Or both of them being Erick. She laid back and started to moan.
“Hey, baby, wait for me!” Erick said, shutting the door and walking towards the bed.
“OH FUCK!” she said in extremely suppressed gasp, knowing she didn’t want to wake anyone up, especially her sister. Her eyes, already adjusted to the dark, saw the realization come over Erick’s face. His eyes widened.
“Ummm, hey bro, I’m just grabbing something I needed really bad,” Her voice trailed off drowning in embarrassment, trying to hide her dildo’s and sit up.
“Something you needed? What did you need?” Erick said softly. He came close to her and let the towel he had wrapped around him fall to the floor.
“I needed to get something to take care of me.” She moaned in the darkness, getting a full view of Erick’s body. He was muscular but had put on some weight over the years; his cock was long and hard, standing at full attention.
“Do you think maybe I could help?”
“Fuck… ummm.. no… we really shouldn’t…”
“What do you mean?” He asked, now standing directly in front of her. She scooted back some on the bed, catching the sweet scent of soap and pre-cum, glistening on his now throbbing cock. “If I recall, it was you who had tried to start something… something that I think you should finish off.” He squeezed his kegel muscles, making his cock jump within an inch within her face. Although she had tried scooting back, she was now mesmerized by that hard cock. Whatever logical part of her brain was keeping her from doing something terrible began to slowly fade and power down. Instead, her body surged with an aching longing.
“Maybe just a little…” she said, grabbing the balls and cock in front of her.
Erick shuttered; her hands were so cold. “Yea, it won’t hurt just a little.”
“Mmmm yea just a little bit,” she said softly nibbling on his cock while massaging the balls with his hand. She slowly worked her way to licking the cock with long wet laps. His pre-cum tasted bitter, but it was so delicious that she started slowly sucking, trying to get every drop. Although he had initiated, he stood frozen in front of her, breathing heavily. He had just taken a shower, but already he was sweating and lightly trembling with excitement. He needs to relax, she thought.
“Let me get more comfortable.” She said as she laid back in the bed and undressed, tossing her extremely soaked panties to the side. Erick couldn’t believe what was happening. It was as if time slowed down, but he couldn’t react. He had thought about how he wanted to turn on the light to get a good look at her chest. His eyes slowly adjusted to the darkness. From the moonlight, Adrienne radiated as she squeezed her tits and gently tugging on her nipples.
“I can’t believe we’re doing this,” she moaned, now restless with his inaction. “Let me finish what I started.” She positioned herself, so her head hung over the edge of the bed right next to that thick cock and inhaled. “Go slow,” she whispered, adjusting the cock into her mouth and started to suck. She had hated this position with her ex-boyfriend; they had tried it once all his idea. He had gone in with such fury she had gagged and almost thrown up her throat ached the rest of that day, and she swore: “never again.” But now she ached so severely for Erick’s cock in her mouth. She slowly wrapped her lips around his cock and pushed him from behind further in.
“You sure?” He asked, pulling back. Completely white with anxiety.
“Yes, I’m sure I can take it,” she said, now grabbing her tits and pinching on her nipples as she strained to take the cock deeper. Slowly Erick began to move back and forth. He had never done this with his wife. Although adventurous and excellent at giving head, his wife had always needed to be in control, usually never finishing him with her mouth. He couldn’t believe how good it felt, and slowly, he began to push in deeper with each thrust.
“Are you okay?” he asked as he picked up the pace entirely in ecstasy but noticing that his dick was now hitting her throat with ease.
“Ugh… yes…” she said, completely drooling with spit. She reached for one of the dildos she had hidden under the covers and started rubbing it against her pussy. Even without vibration, just the sensation of a hard cock in the back of her throat and the dildo pushing down on her pussy, which may or may not have been in her sister’s pussy earlier, felt amazing.
“I could help you with that,” he said, leaning over her and grabbing the dildo from her hand. He began to slowly insert it, getting a good look at her pussy, glistening wet. “That’s such a nice wet pussy.”
“Oh, fuck.”
“I think I need to taste it looks so good.”
She gasped in shock and anger as he pulled the cock out of her mouth and the dildo entirely outside. “No baby, I need it. I need this fucking cock.”
He awkwardly laid on top of her and self-conscious of his weight rolled over. He inhaled deeply as her pussy was now pressed against his face dripping with anticipation. The sensation was too much; she instantly came. She immediately felt self-conscious and went to get off of his face, but he rammed her pussy into his face and started eating it with a violent fury. She shuddered then returned the favor on his cock.
When she came again, he exploded with her. “I’m cumming,” he warned her.
“Too late,” she thought as she received a massive load the hot thick cum filling up her mouth, she tried to swallow it all, but she still ended up coughing some of it out. She went on to lick the cock clean.
“Fuck”
She rolled off, heaving in complete ecstasy. She knew there was no doubt now she had to find out what that cock felt like inside of her. As he began sucking on her nipples, they noticed a light flick on. They completely froze. Seconds went by like hours.
“Fuck fuck, we fucked up!”
They heard the shower cut on.
Erick and Adrianne scrambled furiously to remove the blanket open up a window turn on a fan. She suppressed her laughter as she grabbed her dildos and kissed him quickly before scrambling away.
