A Stepmother's Sin - Chapter 5: I try to understand what is motivating my stepson

... the front door when I got you to slow down and reconsider. I just hope you didn’t leak any of your little 'spermies' into me. You could be one minor plumbing leak from having a brother and son in once fell swoop.” I continued to stroke him, and he continued to rock his hips as we talked. “Mom, I know. I know I was already in a bit. It was all I could do to keep from plunging into you. It was really tough for me to pull back and wait.” “I know, Robert. But you must never do that.” He nodded in agreement as he humped my fist. I decided that Robert needed to articulate that fact. “Repeat after me ‘I will not try to fuck my mommy unprotected any more.’ Go ahead, let me hear you say it.” Robert made an expression that indicated he thought this little exercise was silly. He seemed like he did not want to say those words. So I stopped stroking his erection for a second and waited. Robert quickly relented and said, “I will not try to fuck my stepmom unprotected any more until she is on the pill, which she needs to take care of right away. I promise.” “One more time…” “I will not try to fuck my step mommy bareback any more until she is on the pill. I will not pump my stepmom’s pussy full of my potent cum….” He just could not keep from ‘cracking wise’ with me, even on this subject. The fact that he was obviously very proud of his virility and the 'potency of his semen' was not lost on me. I wondered if, on some level, he did actually want to impregnate me? I put that thought out of ...

... my mind momentarily, but made a mental note to get on the pill quickly as a preventative measure. “Good boy.” I brought his erection to my lips, kissed it several times, placed the tip of my tongue into the opening slit. A loud guttural moan escaped him as I tongued his slit which told me he liked the tip of my tongue probing his urethra. He liked it a lot. I took him into my mouth and slowly brought him to a slow torrid orgasm. As he came, I continued to suck and swallow; I certainly did not need my stepson’s cum spots on my business suit. Beside, I had recently learned that I found the smell and taste of Robert’s semen enjoyable. Who ever would have guessed? When I thought he was done ejaculating, I took him out of my mouth, but another small translucent white drop appeared on the tip of his glans, I leaned forward and licked it off, realizing that I truly enjoyed the taste of Robert’s semen. Swallowing him seemed the most natural thing in the world now. “Thank you. I needed that.” “I know you did, baby. Go get dressed, I have to go.” I stood up and hugged him. I noticed that he made no attempt to kiss me. It was clear that having just cum in my mouth, he did not want a taste of his own medicine, so to speak. Men are strange animals indeed; they love to have us women ingest their semen, but they want no part of tasting their sperm themselves. Moments later, as I walked out the door, I heard him say, “Mom, I love you so much.” And I knew he really did. At the office... I ...
