I asked nothing of her background beyond getting an early verbalconfirmation of her sexual proclivities and later, as we got to knoweach other better,...she told me more about herself and her interests.She had been married for about ten years but her ex left her when theydiscovered she couldn't conceive. She'd had a couple of flings withgirlfriends while in college and found she'd liked it and so had beenthinking seriously about returning to the "life" as she called it,feeling somewhat soured on. And when the knot enters, I have a feeling I would cum like never before. Theres only one hitch-I dont have a dog. At my dads place, he has a beautiful red heeler named Ranger. I honestly dont know if Ranger has ever had a chance to knot up with a female before-hes been around female dogs in heat and showed little to no interest. I dropped by my dads last night to drop off a prescription I had picked up for him and he wasnt home yet. I could have gone ahead inside, put the meds in the fridge,. I did my best to hold my breath and not give any evidence to my mom that her son was in his sisters room with no pants and a rock hard erection.“Okay, do you need to talk about it?”“No! It’s fine mom, goodnight.”“Oh-okay. Goodnight Ava, love you.” My mom said before heading back to our parents room.When we were sure the coast was clear I took a step out and looked to Ava. “That was too close.”“Yeah, sorry. But I couldn’t help it you made me feel so good.”“I should go.” I whispered walking. Watching the nervousness in the couple, she sat quietly. He said, "Have you been with her already?"The woman bowed her head and shook it slowly as she said no. He heard the sound of her swallowing the wet that formed in her mouth. He knew that sound and knew she was turned-on. He asked, "Are you sure about this?" I'm sure I want her. Not sure I can take your pleasure in it." Knowing how possessive she was, he knew her concerns but his nature had to ask, "What do you mean?"She looked away from.
