She pulled me up and asked me to join her. It was really weird, and I tried to calm her and stop the music.I told her she needs to get some rest and t...at she’s drunk. Then suddenly she sat down and started crying. I couldn’t understand what was going on, so I sat down beside her and asked her what’s wrong. She told me everything about how dad cheated on her and that she’s heartbroken.I was really upset. I hated to see her like that and tried to cheer her. I tried to change the topic to take her. 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 inhaled my cock past her pink lips. I groaned as my baby sister nursed on my dirty cock. She sucked it clean of Alison's asshole, staring up at me, her cheeks growing redder and redder.“And what are you going to make me do?” Alison asked. “Are you going to. I flicked his finger against the nubbin, and mom groaned. I lifted his hands and pulling the waistband of her panties out with one hand, I slipped my other hand against her trembling belly and slid it down to her pussy. Stopping there I turned my palm upward and with my other hand thumbed her panties down over her hips. My mom rose slightly as the panties slipped under her ass and crept to her knees. I didn’t bother to remover them entirely. I liked to see the panties there to remind me that. The Dom put the large vibrator against the subs pussy and started to push. I heard the sub utter a guttural moan as the cock penetrated her pussy. Then she threw her head back and growled through clenched teeth as the cock went deeper and deeper. Her knees were bending and flexing as the cock disappeared between her legs. But the real action came when the Dom reached down to turn it on and I could hear the low hum of the vibrator as it started sending waves of pleasure through the sub's.
