There’s no suspicion in a sister visiting her brother’s new apartment.Mark held my hand as we entered his apartment and he closed the door. We loo...ed at each other for a few seconds, and then we kissed. Passionately. He lifted my buttocks and carried me to his bedroom.Still glued to his lips, he placed me onto his bed. He peeled off his top, revealing his gorgeous muscular body. It seemed even darker than I remembered. I placed my hand on his chest, noticing my wedding ring.“Oh, Mark, this. That is, if I don't eat chicken soup, my cum doesn't taste like chicken soup," I added as I pulled up my pajamas bottoms. She agreed and proceeded to get out our books and for the next hour we concentrated on classroom chemistry. Then it dawned on me I could teach her something about pussy juice chemistry. I asked her if she liked caramel sundries. She said she did, so I made her a small salted caramel sundry without letting her see me add the salt. With the first bite, a questioning look. Just fuck me ... I'm ready."I lifted my eyes quickly to meet hers. "Doesn't matter ... you're going to get it anyway, because I want to." In the next instant, my mouth covered her pussy, and my tongue wormed its way between her slick folds, then moved from her opening to her clit. She yelled again, and I felt one of her hands clench in my hair, pulling my head into her. Her hips lifted right away to meet my face, and I knew she really didn't need any further foreplay. I wanted to feel her come. The moment the door closed, the two women were all over Barb. Lee kissed her, a long deep lingering kiss, then Denise followed with another mind-blowing tongue swab of her throat. Then the two younger women began to kiss in front of Barb, their hands moving over each other's young bodies. Barb's already rising excitement threatened to make her dizzy as she watched her partner kiss another woman. Then the pair turned their attention back to her, moving to either side of her and showering her.
