When Ben began to breathe faster and moan louder, Claire knew he was ready to cum and picked up the pace of her hand movements. He was thrusting his hips in rhythm to her strokes and grunted loudly. Ben’s cock began to spasm, then he shot a huge load of cum onto his step-sister’s stomach and tits. Ben kept cumming and cumming, shooting wad after wad onto his sister’s naked body until his balls were drained dry.
Claire never released his dick from her hand and Ben noticed a look of lust in her eyes. He decided to run his hand between Claire’s legs and, once again, finding no resistance, he inserted his finger into her pussy and began to finger fuck her. Claire half-heartedly asked him to stop but instead, began to thrust her hips up to meet his finger. Ben then inserted another finger into his sister while his thumb played with her clit causing Claire to cum again.
With Ben being a horny nineteen-year-old, he was hard again and Claire felt she should return the favor and jerked him to his second orgasm too. This one took longer than the last but she also got to play with his cock that much longer until he came again, leaving a second load on her stomach and breasts.
There was an awkward silence until Claire said, “I’m exhausted. I’m going to take a shower and go to bed.”
“Yeah, uh, I think I will too.”
Claire had a mix of emotions. She was tired, felt guilty for what she had just done but also excited by the sheer naughtiness of what just happened with Ben. It was so taboo but that’s also what made it so much fun. She never had a guy care as much about her needs to bring her to two orgasms either. Ben didn’t feel as guilty; he was more worried about Claire. He wanted to fuck his step-sister but knew she wasn’t ready for that. That is probably the difference between a teenage young man and a woman. It was awkward the next morning at breakfast. Claire was dressed more modestly but Ben felt comfortable in his boxer briefs.
Ben mentioned, “I had fun last night. I hope you’re okay.”
“I think we both got carried away last night. Don’t get me wrong, it was fun, but it can never happen again, Ben.”
“I understand, Claire.”
Claire didn’t want to admit, even to herself, that she secretly wanted things to progress further. Ben was disappointed because he was hoping for more of the same action or more, seeing his parents were going to be gone for several more days. They were both quiet during breakfast, then went about their day.
On Saturday night, Ben and Claire decided to have a small party with several friends, nothing too wild but with music, liquor, and swimming in the pool. They almost felt obligated to have a party with their parents out of town. Things were pretty normal, with some single friends and couples invited. Everyone was having a good time partying.
Early in the evening, Claire’s best friend, Lisa, came up to her and said, “I can’t believe how great your little brother looks. I don’t remember him having all those muscles. Damn, he looks good.”
“Yes, he certainly has grown up.”
