Apparently the tight crotch of my jeans placed just enough pressure at the right spots that my penis started to wake up. At first I felt my penis thro...bing slightly, then it grew a bit and pushed around my crotch. I rubbed my crotch to relieve the pressure. My penis responded by throbbing more, and then it started to happen. My cock just swelled up. I touched my crotch and felt the hardness of my cock.Just then I noticed a young twenty something blonde open the door to the building and walked. She was tired and had developed pain in the back and so we took a brief break. But I did not leave her alone, otherwise her drive will go down and so I went on caressing her boobs. Then I made her to stand like a dog and entered her pussy from behind, this was easy, as she was sleeping on the bed with her legs hanging by the side of the cot and I was standing by the side of the cot. It was convenient for me and for her too. And we continued fucking again, in this pose for some more time till it. I stood and, with my back toward her, I stepped out of my underwear and showed my mother my naked butt. When I again turned, this time showing her a hard-on and a beat-read face, she had removed her hand and arm and lay nude in front of me.I feasted my eyes on her body for a while and then she blushed a little more, if possible. Saw that her tits indeed were small, with pink nipples that stood out in the hot water. To me they were prefect! Not to mention the pussy! Thick blonde hair that lay. I was in jeans and a white karate tournament T-shirt. I was on the couch watching Air Wolf or Night Rider, some dumb ass early 80’s show. She walked past and behind the couch and gave my T-shirt a little tug at the shoulder from behind, and looking back at her as she took a sip through the straw of her drink, she gave me that tip of the head that meant, “Come with me.” And I followed her into her bedroom. Once inside she closed and locked the door behind me, took a sip of her drink and placed.
