She pushed me deep into her cleavage, squeezed tight around me, and then looked up.“Do it. Fuck my titties and come all over them,” she pleaded.I...began to thrust – slowly at first. She subtly shifted position, leaning back, and provided me the perfect angle. She didn’t need to say it when I began to slide comfortably between her tits. Her eyes absolutely screamed, do it.So, I did.I fucked her tits, marveling at how she consistently juggled the big globes, keeping them wrapped around me. . I simply assumed that he must be elsewhere, or Sonia wouldn't be acting like this. It still hadn't dawned on me exactly how kinky my brother and my sister-in-law really were. I had no idea that horny old Bob was hiding in the closet, where he could peep out through the crack in the door at us... watching for just the right moment.When I spread Sonia's legs and bunched her slip into a roll of slippery fabric about her waist, I wasn't thinking about anything except the tasty beauty of her red. "NO!" I shouted and stood up, knocking Trisha onto her back in the middle of the floor. I pulled my dressing gown closed about me and looked down at the startled woman lying at my feet."What the... ?" she cried."I can't do this Trisha." I stated firmly. "More than that, I don't want to and won't." What do you mean? You can't do this." I could see the anger in her eyes and I also felt that strange pull that seemed ever present when in her company."What's the perfume you're wearing?" I asked and. Your mouth assaults my senses, pulling my nipple into your mouth and sucking hard.Sharp bursts of arousal move through me and my pussy begs for attention. Your fingers drag across my skin and dip down between my open thighs. One finger slides slowly inside me, gliding easily into me through my slick juices. You don't leave it there though. As quickly as you entered me, you were gone. Raising up on your elbow, you smile slyly as you bring your hand up to taste my pleasure.I need the attention.
