He did not knot with me. I think, initially, I had assumed the large bulb at the base was somehow associated with his balls. He ran around me, I got t... see his cock. I could not believe that had been inside of me.He mounted me again, slipping easily into me now. Fucking me hard and fast. There was something different this time. A kind of desperation. I felt something bump into me, several times and then it was inside me. Scared, I went still, feeling this thing, whatever it was swell inside me.. Pain was now decreasing. Now I started enjoying after some time he increased his speed and now I was also moving in rhythm.I started enjoying it and pain was very less. He then again increased his speed after 2 minutes he told that he is going to have orgasm. So I told him to remove and he ejaculated on my body after 5 minutes he was hard again and again he started fucking me and this time within 1 minute I had an orgasm.Then he again ejaculated outside after some time. We both were now. I brought my short and gave it to her. After she wore my short, she came back to hall. Seeing her like that aroused me. We sat on the couch and started watching GOT. Few scenes in the show made me hornier. She was very comfortable watching the show with me. I naughtily asked her if she have ever watched porn. She laughed and replied that she has just seen it once, that too because her bf insisted and she didn’t liked it at all. After a while she asked me the same question. I admitted to her. I helped him out of the rest of his clothes as he stood near the side edge of the bed I stared at his fully erect cock with pre cum dripping down from the tip. I u*********sly licked my lips still horny and becoming curious about sucking my Dad's cock I grabbed a hold of it stroking it a few times as I looked up at him and smiled he caressed my face with his strong hand before I leaned in and began licking and sucking his hard cock letting the pre cum coat my lips I began sucking on his head.
