... feel like doing." I swallowed again and my mouth was suddenly feeling very dry. My dick was semi hard now. "But," she continued, "One thing is totally off limits. You may not ever penetrate me. That would be completely wrong." I blushed deeply at her words, knowing that she had thought I wanted to do that to her. Fuck, yes I did, but mom knowing that at this stage, felt deeply embarrassing. "Ok, mom," I said in a high-pitched, embarrassed tone, trying to make out it was no big deal. I felt a tinge of disappointment run through me. "And one other thing, is that I may do or suggest other things which women normally do to turn men on, which will also help you to cum," she added. "Like what?" I asked, curiously. "Well, we'll see," she said, a bit mysteriously. "Why don't we wait for our sessions and then it will be more stimulating for you." As she spoke my mind became flooded with things I'd seen in porn movies or in pictures and I just couldn't imagine for a moment that what I had known as my 'prim and proper mother' doing those to me.
