Nikki began to protest when she felt Andrew shift his body, not wanting to be separated from him just yet.  But she just smiled happily and nuzzled into his chest as he flipped them over.  Her legs were straddling his hips and she moved down a little so his shaft was still deeply within her after their kiss.  She placed kisses along his chest as her pussy continued to squeeze around his cock.  "I missed you too, baby.... I wanna taste us." She said, giving him a wicked grin before sliding her pussy off of his cock and making her way down his body.  She knew his cock was still hard from how it felt sliding out of her and she could see it glistening with the mixture of their cum as she got closer.  Gripping the base of it in her hand, she looked up at her brother as her tongue poked out and slowly flicked against the head of his cock.  "We taste good together..." She said before lowering her lips around the head of his cock before slowly moving down, taking as much as she could before pulling off and repeating the action.
