She crashed into orgasm and called out incoherently. She felt her eyes roll back and she babbled and shook through his thrusts She felt his cum inside her and tried to beg for more, but her mouth just moaned and seethed. If he were lighter she might have thrown him off, but he continue to hold her down and pound her cumming body into the sheets, extending her pleasure further and longer and filling her up with cum and sex. Her throat was sore by the time his thrusting slowed and her climax began to leave her in layers of submission, pain, and ecstasy. Her ass gripped him tightly as his cock began to shrink and leave her.

She felt like used condom, but in the best way possible. She was a sex object, and a good one. A loved one. Even if she was never used again her body and mind were completely his for now. He was her husband, just for the hour. And she was his whore, his slut, his plaything. That was what she wanted.

When he finally released her and his cock was limp she flopped to her side in exhaustion. She felt the cum inside her leak out and run down her leg to the sheets. She felt him cuddle up behind her and hold her tightly. They were both out of breath. "I take it you like that?" He asked. "You usually aren't into anything that much." He caressed her side and she felt electricity tingle from his touch. She twitched as he teased.

"Let me think about it." She settled on saying. She didn't want to land her sister with anything. "But that was good. That was really good."

"Great." She felt him touch her side again and realized that if this continued, she'd probably be up for another round. As great as that sounded, her stupid mind remembered her that Robert was Donna's husband, and that this was just a favor to her. She had to get to the mall or risk feeling even more guilty than she already did, and risk being found out.

"Hey," She touched his strong hand with her own, "I just remembered that I've got an errand to run at the mall."

"Your sister?" he asked.

"Yea. She needs a favor. I'll call you later okay?"

"No problem." He got up and stretched. "But before you go, there's something you might want to tell her."

Jamie raised an eyebrow. "What?"

Robert stood up, put his boxers on and turned to face Jamie before he left the room. "Donna hurt herself cooking last week and it left a nasty cut. So try to remind her to get more band aids before she comes back." And then he left the room with a smile on his face.

It was definitely intriguing to wonder how this was going to end, and he’s clearly a good lover so, hot. However, his last line was close to cruel and humiliating, so casual and dismissive. At what point did he realize it was his sister-in-law and why did he keep going as if it was nothing? Does he have no idea she actually loves him—which seems implausible given her seemingly sweet personality and how many years she’s had to be around him? (It would have shown.)

It bothers me deeply that she said, “I love you” almost helplessly while in such a vulnerable emotional and physical state, because we know how much she meant it. Only to have him hop out of bed, ridicule her and what they just did together, and then stroll off. He should have zinged his wife with that line sometime after she got home to shame her. Even better if he had let Jaime know in the middle of sex that he’d realized it was her, and then made love to her longer and better than he did when he thought it was Donna. Why couldn’t Jaime have her moment with the person she loved even if it never happened again after he let Donna know she’d been busted.

This ending, ugh, just broadcast’s Jamie’s continued sadness and longing for his love that led her to subject herself to the whims of both him and her sister as if she were some toy for their amusement. If you ever get the inspiration for a part two that gives Donna her comeuppance (maybe having to share him?) and Jaime real love and care from Robert—or maybe closure and happiness away from these two (if Robert can’t learn to love her sincerely and openly as he does Donna)—I’ll be here.

Good story with a fun premise. I've known twins who traded boyfriends for fun just to see if they could get away with it. - success rate of getting away with it seems to be about 75% for identical twins. He should have kept it a secret that he knew, and then enjoyed Donna's ass the next night. Maybe wait until they were all having dinner together some night and then casually mention how glad he was that Donna's cut had healed so quickly.

Wonderful premise, but it feels rushed, and no prep. I jalso ust couldn't get past the grammar & homonym mistakes.

taught assets > taut assets

once your done > once you're done

impotently wet > ???

cracked out a wine > cracked out a whine

I was hoping the twins got away with it.

AnonymousAnonymousover 1 year ago

I can't believe that Donna forgot about the cut. It totally eliminated the idea of the twin's being identical.

Nice, 5 stars. Donna should have known that twin switch may work with dating, but after being married a man knows his wife’s body too well.

AnonymousAnonymousover 1 year ago

Interesting premise.

But rushed.

Needed much more in the way of prelimimaries/foreplay before cock enters ass.

Lots of touching and caressing her asshole. Insertion of a finger tip to loosen her up. Lubrication application. Followed by some more serious fingering.

Maybe she could have reached around to his cock and played with it -- and his balls. She could have lubed it up and teased him with a slow handjob for a while...

Four stars.
