Jean tastes her brother’s cum.

Cassandra was very nearly breathless and Michael still wasn’t sure what he was seeing. On this stranger’s suggestion, his big sister had stroked him to orgasm in front of all of these people, and now she had raised her cum-covered hand to her mouth. Was this really happening? Cassandra’s fingers were still wrapped around Jeannie’s wrist.

Michael's heart beat in double time as he watched his big sister's hand draw closer to her lips. A small drop of his semen dripped down her hand and into the tub.

Jean could smell it. How had Michael cum so much? She knew that the little perv had to have been jerking it every night in their hotel room, so he should have been... spent. But he wasn't, apparently. Maybe that had something to do with the fact that she, his Jeannie, his older sister, had just masturbated him in front of a gang of strangers. What kind of sister was she?

"C'mon Jeannie," Cass cooed.

You know you want it, was the unspoken urging. Jeannie's stomach turned over. It was so hot and so thick, and she could feel it dripping down her hand. She was losing some of it every second. She had to--

Jean raised her hand to her lips and opened wide and everyone saw her lick a big glob of her brother's cum off of her hand. It sat in her mouth, salty and warm and covering her tongue, and she swallowed it down.

"Holy fucking shit," Jon gasped with a grin on his face.
