My son Tommy came over and took off his T-shirt and with just his boxer shorts on, climbed under the blanket. I had no panties on and the lingerie was sheer. I pulled him over to me and we cuddled each other. Feeling his embrace I said “Tommy, you are a strong man, you are crushing me!”
“I love you mom,” he said and gave me another bear hug and kissed my cheek
“I love you too” and kissed ‘innocently’ on his lips which I do often. But this time I kept my lips on my son’s for a perceivably long time and mumbled without opening my lips, “My sweet little baby.” “OK mom” Tommy tried to say with my lips still on his, and saying so, opened his mouth when I felt the wetness of the inside of his lips. Without relenting, I planted one more firm kiss on the inside of his lips by nudging his lower lip down with mine.
Then I turned it into a kissing game. I moved the blanket down. “I love you Tommy” and kissed him on his cheeks and then his chest and then his tummy. Then I kissed his left groin but made sure that my nose touched his penises as I moved on to kiss the right. Then I moved on to his thighs and then his legs and finally kissed and gently put my lips around his big toes.
He immediately withdrew his legs and moved to the lower and of the bed where both I and my son were now sitting. “Show how much you love your mom, Tommy”
“A lot!” he said. “Kiss and show” I demanded and lay down on my back with my left knee raised and the foot drawn almost to my right buttock. My lingerie had ridden to the top of my thighs by now. Tommy, as he was kneeling by my right side, I beckoned him with my hands to start kissing and pointing to my cheeks, said, “Start here”. It was a gentle command which he readily followed.
Attention to the Breasts: He kissed my cheeks and waited. I encouraged him “And then…?” He straightened himself up and looked at me unsure. “Go on Tommy.” I waved my left hand across my entire body. Tommy bent down again and kissed my chin and then my stomach.
“Nothing in between?” I asked my son, smiling. “And that is all that you wanted as a baby,” I continued. Without lifting up his head and looking at me, Tommy gently went on to kiss each of my left breast well above and far away from the nipples. When he moved on to my right, I guided his head towards the nipple and said, “That’s where you kiss them”
As I felt my son’s lips against my erect nipple, I pressed his head gently down on to the flesh of my breast and asked him to kiss the left one also the same way. I was pleasantly surprised that this time not only that he went straight for my nipple, but pressed his lips around it nibbling it playfully. “Wow..!” I said, “That felt well, Tommy”. I wanted him to feel totally encouraged. And then I pushed his head down to my belly which now he kissed over the lingerie.
My lingerie now up to my waist, I turned face down exposing my totally bare buttocks for him to kiss. For a brief moment, between me lifting the lingerie up and turning face down, I watched my son look at my pubic hair that had missed seeing that afternoon in the living room couch. Now face down, I pointed my finger at my ass and said “And there.” He did that without any hesitance. By now my son had developed a big erection that was easily visible through his boxer.
As Tommy kissed my calf, I said, “OK, I know that you love me.” I turned around on my back and with my lingerie now riding high till my belly button, asked my son to lie over me. With the game now well under way, he readily did that. Oh and we had lots and lots of fun.
These moments always seem to start with a kiss. You lean toward me, a smile playing on your lips, and look up at me with those beautiful eyes. How can I resist?
