" Caroline smiled at both of us before continuing with Vikki. "Before we decide what to do this afternoon, would you like to see a couple of paintings...from one of my notorious exhibitions?"Vikki nodded her head enthusiastically.We walked up the stairs and into the studio with Vikki holding my left hand while the naked Valerie held my right. Vikki had her eyes closed at Caroline's request because she hadn't seen the two pictures hanging up on the wall.Her reaction as she opened her eyes was. V. it started to get late and I was just coming out of the bathroom and I pasted my sons room and heard low moaning, I stepped closer no making a noise and listened at the door and it was clear they were watching porn.I have to say I do it myself and enjoy a good wank but something about knowing my son and his friend were watching porn got me so wet I could feel my pussy staring to tingle wondering what they were doing, before I knew it my hand had slipped inside my pants and I was fingering. ." as he began to lose consciousness, hiseyes failing to keep open. Tiffani pulled herself out of him, and beganto laugh "Hahaha, I can't believe who fell for it!" Marc looked down,noticing his man rod covered in the condom was looking funny. Oh shit,he realized, she must have poisoned the condom or something. "Why yes,Marc, that condom contains some poison which easily penetrates you fromyour nether regions, just as you penetrated mine-" Marc looked on inshock as Tiffani got up from the bed.. My sister smiled and said, “Oh today’s job is not yet over. Be gentle, you’re very horny today.” I smiled and kissed right from her toe and rubbed my lips through her knees, then inner thighs. Finally landed on her pussy with a soft kiss. I poured some honey on her pussy.I caught hold of her hands now. I buried my face between her thighs on her pussy. Started to slowly lick the honey with her juice. As I started to play with my tongue inch by inch on her pussy, my sister began to let out moans..
