She went to work sucking his dick like a pro. Seeing her sucking his cock while she pushed back on my dick, had me so hard, I could see her pussy gett...ng creamy wet. She loved being such a dirty fuck doll.My girlfriend stroked & sucked his dick, fucking her wet mouth as much as possible. Each pump by me from behind into her tight little pussy sent his dick further down her throat. He'd hold her head on his dick for a few moments, making her gag & drool. She'd let out a moans of pleasure, all. “Makes your mouth water. It's better than sucking on your thumb. Your thumb is just a substitute. This is what you truly crave.”Livie pulled her thumb out of her mouth. Her eyes were so wide. She blinked, tears clinging to her eye lashes like diamonds. Then she crawled towards me, looking so childish, far younger than her eighteen years. She reached me, her little nose twitching as she inhaled the sour musk of our sister's asshole.Then she let out a whining moan, opened her mouth wide, and. She paused briefly at that last comment. Then she carried on out of the room and up the stairs. "I'll be here if you change your mind." I shouted after her arrogantly. ** I sat on the couch alone. I was cursing myself for ever bringing this issue up. It seemed almost certain that I had blown it. I went to the kitchen and grabbed a beer. I headed back to the living room and wished I could have gone back 10 minutes and said nothing. I sat watching TV for an hour before I heard some movement. She gasped and opened her mouth. She fell on me helpless and this made her boob go deep into my mouth. I put her nipple between my teeth and started to bite it. She moaned loudly and pushed her hand into my shorts suddenly. She grabbed my cock and squeezed it.She ran her finger on top of my cock. My cock’s hard already and pre-cum oozed out of it. She squeezed the red ball and I jerked in her lap and I released her boob from my mouth. She moved back and I was gasping for breath. I looked at her.
