We moved slightly to tickle, not using any of our strength at all just moving enough to stimulate what was going on down there. Not more than a minute of this and I could feel myself getting ready to climax. I figured that if I came in her, then this whole incident would have been innocent and would look like I was the innocent one who was not oblivious to it but also didn't feel a thing. She the jumped on me a little, pretending that I had ticked her and made her jump. That did it and I erupted in her. She must have felt something strange inside because soon after, even she started to shudder. We continued to feel each other up in the pretence it was tickling while we came together. After what must have been about a minute, I regained normal consciousness and realised the implications of what had happened.
I had fucked my mom on her bed and come deep in her and she had willing participated but neither of us wanted to face reality so we blamed it on a stupid tickling fight. Exhausted, mom returned to my chest with my dick still buried deep in her. I could feel the cum oozing out of her tight pussy as the size of my dick shrunk. I contemplated acting maturely and removing my dick from her in an obvious manner and taking to her about it. On the other hand, leaving it like this and playfully removing my dick while ticking her would keep the innocence.
