I grabbed the other nipple with my free hand and begin to abuse it, tugging, twisting, pulling, and he got the idea. Tentatively at first, he his used...his teeth on the other, biting gently. Still plunging into me with regularity, he then began to bite harder. I gasped at the pain-pleasure combination and pulled his head to the other nipple.Consumed by the lust that surrounded me and continued to thrust deep inside me, again and again, my head lolled from side to side; my eyes lost and regained. Liz stood up with me."Thank you, Mom," I told her. "That is all I can ask."With that I left the room. Liz and I went to her bedroom and closed thedoor."I can't believe you did that," Liz exclaimed when we were alone. "Ijust about had a fit when I saw you in my dress with Mom and Dad." I was afraid if I wore something of mine they might make me throweverything out," I told her."Oh, I wasn't upset about you wearing my dress," she shook her head."You could have worn something of yours; Mom has. ” I screamed. Just as daddy started to rotate my hips OH baby girl you don’t have to worry about that.” He said. As he took one of my nipples in his mouth, as he continues to bang the hell out of me.After Tina moved out my bound with daddy became even tighter. Daddy and I would fuck sometime two or three times a day. We really liked the idea of not wearing any cloths around the house. Therefore, daddy and I adopted a no cloths policy when we were at home. . One day my mother walked in while. Alison it has to be said is not a person who lies there still and quite waiting for it to finish, more of an Olympic coach, encouraging her athlete to do their very best, and if he does then boy hold on tight because you are in for the ride of your life! Well her new found master was hitting all the right spots and Alison was his play thing.At some point he turned her over and was now fucking her doggy, then without a word he pulled out and slid it up her arse!! Not a totally unusual thing.
