I wrap my arms around my son and whisper in his ear that I love him. We kiss and I feel his hard c*** press into my belly. As we are kissing he is squeezing my t***, pinching my n******. He readjusts his position and his cockhead is very close to my entrance. I open my legs more and he reaches down and rubs it against my c***. He says to me. “Please let me put it inside you, I need to see how you feel.” I smile and say, “Honey I have wanted your big c*** in me for a long time. Please put it in and make love to me.” He was ready and so was I. He moved into position. He rubbed the head across my entrance and I moaned out as he did. He pressed his big cockhead into me and slowly I opened. It felt so big as he pressed forward more and I started to open up. Soon he got the head in and it felt wonderful. After some easy stoking in and out he buried his whole c*** in me. A perfect fit. I pulled his head down to bring his lips to mine and kissed him. The feeling of my own son’s big c*** in me was fantastic. Even though he was big, it was like I was made for him. He began stroking in and out. He reached around with his hands and grabbed my a**, pulling my hips to him. He was adjusting the angle, trying to shove more of his c*** in me. He was starting to speed up and I sensed his desire would overwhelm him. Something I hadn’t thought about somehow entered my mind. His father had a vasectomy a number of years ago. It had allowed me to stop taking the pill. Billy was not wearing a condom and I was unprotected. I didn’t think the timing was right but it was still risky. Pregnancy would definitely be hard to explain. The feeling of his big c*** in me made me forget all reason. He knew he was close and asked, “I am going to c**. Do you want me to pull out?” I said, “No baby, I want you to c** inside of me. I want to feel it. Go ahead and shoot.” When a guy hears that is is OK to unload his s**** into a woman, and she doesn’t mind, it is an indescribable feeling. Somehow his c*** swelled up some more and he was really pumping now. I felt a spasm move through it and then he erupted. Wave after wave, rope after rope of s**** from deep within him into his Mother’s p****. His cockhead was hitting against my cervix. He knew where some of this was going. Didn’t he remember that his Dad went through with a vasectomy a few years back and the reason was his Mom wanted to get off the pill? Still, I didn’t ask him to pull out. My whole body spasmed with my own climax. His c*** felt so big as my p**** shuddered and squeezed it. I had wanted this for so long. When we both started to relax and came down from our o***** high, he laid his head on my breasts thanking fate that he had this chance. The chance to make love to his own Mother.
