Then I will let you lick my brother’s cum on my cunt…” Suddenly I felt a toungue on my cock. Oh my God, My jijju was licking my cock!!!!“You l...ke it, don’t you…?? Huh…? You impotent bastard… you like licking your wife’s juices on my brother’s cock, you sick bastard??” But my jijju did not seem to pay attention to crude sarcasm of my sister’s remarks. He knelt behind me as I rode my sister. He even sucked my balls. The poor bastard was demeaning himself too much.“Yes Pooja… I love it…Mmmm…Manu’s. I pulled out my phone and started mindlessly scrolling through Instagram, passing the time until the rest of the group arrived. Since the start of the previous semester, a small group of us had been meeting every Thursday afternoon for what began as a study group for our Contemporary Literature class. It initially yielded a much larger turnout. However, after a few weeks, the number of attendees dwindled, and it turned into more of an informal book club, with only four of us from the original. I had assumed they would not come upstairs right away and I was quickly proved correct as Kathy led Dan into the family room. Dan accepted the beer Kathy offered him and soon they were both on the couch drinking beer, talking quietly, and softly kissing. I sneaked out of the bedroom to the loft where I could watch the action without danger of being seen. Dan began to kiss Kathy more urgently and she let him unbutton her light blue uniform blouse and unclasp her front-opening bra. He helped her. He went right in. I didn't say a thing, just enjoyed how he was humping me. It felt sooo good and he was rubbing his shaft along a side of my vagina that usually didn't get attention.... at least directly. Something was being stimulated that was blowing my mind. I opened my eyes at one point and looked at the mirrored closet door. The image of Cass reminded me of a jockey riding hard for the finish line, except instead of reins he was holding my sagging breasts.Suddenly... I'm sure he came.
