Desc: Sex Story: A cum-crazy Terri takes her kink home, with disastrous results for her nosy little sister.

Theresa squished the used condom in her jacket pocket with her thumb and forefinger as she walked up to her house. Her mind wandered back to her date, now over.

Jay, another senior student, had asked her out during lunch earlier that week. Tonight, Friday, he had taken her to dinner at Burger King (blech), and then she drove them up to "Lover's Lane," where she had proceeded to give him a blowjob. She wasn't "easy," but she had an ulterior motive for the oral pleasuring. She didn't want to mess up her car, she told him, and when he got close to cumming she slipped a condom onto his not-very-impressive cock and jacked him off into it. While he was putting his dick back into his pants she tied off the condom and slipped it into her jacket pocket.

She had planned something like this since she had gotten back home after the summer break. Oh, that summer! She had spent it with her older sister in the big city, and during that time she had discovered that she had a kink: she loved man cum! The feel of it, as well as the danger it represented. Just a small bit at the right/wrong time could make her pregnant, and when her sister's boyfriend had blackmailed her into having sex with him he had put a LOT of his cum inside her for weeks. It was a miracle she hadn't gotten pregnant.

Theresa opened the door with her key, called out to her parents so they knew she was home before curfew, and then headed to her room, palming the used condom as she hung her coat on the entryway hooks.

Once in the safety of her room she closed the door, took off her clothes and reclined on the bed. There's nothing more comforting than the feel of your own bed beneath you, she mused, sighing. She opened her side drawer and extracted her vibrator, and then dropped it on her flat stomach as she untied the condom.

She gave the contents a sniff. Even though she purchased the most basic condoms she could find, it still added a chemical smell to the cum. How far would she go to get some that smelled like it should? She shuddered at the thought.

Her pussy was very wet now, and her long pink nipples were erect. She put her index finger into the condom, extracting some semen, and rubbed the rich cream on her nipples. God, she missed cum! It had been weeks since summer break, long enough to have her blessed period and for that to have just finished yesterday, which had reawakened her sex drive. She should be safe enough now...

She licked her lips and put some more cum on her fingers. Those fingers wormed their way down, down, toward her throbbing womanhood, leaving a slick white trail as they went. She skimmed her fingers along the ends of her trimmed pubes, and then lightly rubbed her outer pussy lips. It felt good!

Leaving the little bit of man cum on her outer labia, she took the vibrator and turned it on. She also had a dildo but when she had returned after summer she found it just didn't "do it" for her anymore -- not after getting fucked for real -- and bought this bad boy with her remaining "mad money." However, she still couldn't cum very hard without the man cum doing its magic on her.

The vibrator hummed as she moved it down to her nether regions. She touched it to her clit and jumped ... she was already too stimulated for that! She moved it lower, rubbing the head along her outer lips. She could see it becoming slick from her juices, and the semen she had left there!

She looked at the dangerous juice on the tip of the vibrator ... should she do this? If she started again, would she be able to stop in a week or so? The vibrations along her outer labia were being absorbed into her skin, stimulating her clitoris lightly.

I will be careful, she promised herself, and dipped the head of the vibrator into her hot, moist pussy. The feeling was overwhelming, the vibrations stimulating her, inside and out. The knowledge that she had just pushed some of Jay's sperm inside of her thrilled her ... A LOT. She started cumming only a few seconds later, with only a third of the 8 inch vibe inside her.

In the bedroom next door, Theresa's younger sister Penny looked up from her computer. What was that noise?

After she had come down from her cum Theresa extracted the vibrator from within her and switched it off. Holy shit that was overwhelming! Cumming from her old dildo when she was playing with sperm was one thing, but this was intense! The vibe had been a good purchase, she affirmed herself.

She held the condom with one hand and pushed the vibrator down into the rubber so that the head of the vibe dipped into the semen. She took it back out, switched it back on, and returned it to her pussy. The combination of the dripping semen and her own orgasmic juices allowed it to slide back in easily. Theresa felt so full.

I'm doing it again, she thought, I'm pushing the stuff that makes babies inside of myself! Her pussy felt afire, and she pushed and pulled on the vibrating phallus, bringing herself closer and closer to release.

She thought about the sperm inside her now, doing their thing, moving deeper inside her and tirelessly searching for her egg. Oh God! Her breathing was ragged.

Penny moved to the wall, cupping her ear to it. What was Theresa doing to make that buzzing noise, and was she gasping?

"Cum in me," Theresa whispered. "Put your cum in me..." She was remembering the summer break, when her sister's boyfriend had had unprotected sex with her, filling her with his seed. Her hand moved faster, and the vibrator moved in and out, slick with two people's cum.

Theresa had read up on the female fertile cycle long ago. She knew what happened when a woman orgasmed while semen was already inside her vagina. Her cervix would open up and draw any of the semen near it further inside her, increasing the chance of pregnancy. It was so fucking hot!

"Uh ... uhh..." she gasped. Close, so close...

Penny realized that she was hearing her sister pleasuring herself. Holy shit!

"Uaahhh!" Theresa came, lifting her pelvis to get maximum penetration. Her cervix did indeed open up, pulling some of the small amount of sperm she had pushed inside herself further inside. The sperm continued on their preprogrammed journey into her depths.

After a minute Theresa recovered enough to re-tie the condom and secure it in her side drawer. She also wiped off her vibrator and plugged it into its charging cable, which she had wound through the back of the drawer to hide it. One nice side effect of the charging cable was that it kept the vibrator warm, and when she put the vibe on top of the used condom it kept the semen warm, and the sperm alive longer. Even with that she figured she maybe had a day or so of "life" from the condom. She wasn't going to waste it.


Theresa woke in the night. The "itch" had returned, and she knew what she had to do to satisfy it. More of Jay's cum was sucked deep inside of her reproductive system from the vibrator before she was able to return to happy, sated slumber.

In the next room Penny had also been awoken when the buzzing and gasping sounds resumed. The younger girl had played with her own clit while listening, though she felt wrong pleasuring herself to her sister's moans, and stopped right after Theresa was done. She eventually fell back asleep, unfulfilled.


On Saturday Theresa helped her Mom in the garden. While she was out there Penny decided to have a look at what Terri had in her room that made the buzzing noise. She tiptoed into her sister's room, looked under the pillow, under the mattress, and had just started to open Terri's bedside table drawer when she heard footsteps approaching. She had just managed to close the drawer when Terri burst into the room.

"What are you doing?!" Terri cried out. "Get out of my room!"

Penny had spied the vibrator just before closing the drawer. She didn't let on she had seen it, though. "I was just ... looking for a pen... ?"

Terri shook her head, disbelievingly. "Yeah, right ... OUT!"

As the 15-year-old tromped past and out the door, Theresa thought about how she and her sister were so dissimilar. Theresa, bespectacled and brown haired, liked reading and quiet nights at home, while Penny, blonde and leggy, couldn't wait until she could start dating a few months from now at age 16, and would probably never be home on any given night once she obtained that freedom. The two girls just didn't get along, and the fact that youngest child Penny got along better with her older sister Bethany than her didn't help either.

She thought back to the summer visiting Beth, which reminded her of all the sex she had had with Beth's boyfriend Jeff. Instantly her pussy got wet. Damnit! Her Mom had sent her inside to get warmer clothes because the wind had picked up ... would she miss her for a few minutes? She closed her door and whipped her pants off, grabbing the vibrator and condom. She smeared more of Jay's cum on the electric phallus and pushed it into her slick vag as she squatted down. Unhh! So good! She furiously manipulated the fake cock in and out as she crouched there until she came hard on it. When she removed the vibrator it had some of her cum on it but she couldn't spot any semen. She had a nice orgasmic "aftershock" at the thought of the sperm swimming inside of her.

As she cleaned up the vibrator she thought about how close her sister had come to finding it. She didn't think that Penny actually knew about it; she was probably just snooping, she thought. She put a few items from the top of her side table into the drawer to block direct line of sight to the vibe and the condom, which looked to only have one "session's" worth of semen left. She sighed. She would have to regulate its use and get some more on Monday.
