MY SON’S NEW GIRLFRIEND

Some weeks ago, after diner time while my 16 year old son Bobby was up in his room doing homework, the doorbell rang. I opened the door and there was a pretty girl standing there. She looked about 18, cute with a trendy look: a few piercings and short blonde hair. «Hi you must be Bobby’s mom, I’m Nikki. I’m here to study with Boddy» she announced. Seeing my puzzled look, Bobby had’nt said anything to me, she went on: «Math, I’m tutoring him, I’m a teaching assistant. It’s part of my college degree». Before I could answer, Bobby came running down the stairs. «Oh you’re here» he said. «Uhhh Mom, this is Nikki, she’s helping me with math» he managed to say all flustered. To which I replied «Yes, she just mentioned that. Had you forgotten to tell me Bobby». «Uhhh oh sorry Mom, slipped my mind» he said. Slipped his mind, a pretty girl was coming over? My mother’s instincts were telling me there was something more to it. «Well, don’t let me keep you from getting better at math!» I shooed them upstairs.
For the next few weeks, Nikki was over quite often to work with Bobby and his grades did improve significantly and as a bonus, his room was always spotless and he was always well showered. I was pretty sure he had a crush on her but then most boys probably had one on her. It never entered my mind that she’s be interested in a 16 year old teen boy.
Well, last week, while Bobby was off to school, I was sunbathing in the yard and again my mind started to drift with dirty taught about Mike, my strong black lover and… about Bobby when he had spied me touching myself under my bikini and I had seen him jerk his large young cock until he came moaning my name. My hands were quickly inside my bottoms, softly rubbing my wet pussy. I had’nt had a chance to see Mike in over a week and my libido was in overdrive and I was quickly close to orgasm when I felt more than heard a presence.
I opened my eyes and looked up to see Nikki standing there!! Startled, I pulled out my hand and try to cover myself. «Nikki!! What are you doing here?» I blurted. She did’nt answer at first, just sat down on the edge of the chair I was lying on and looked me over. «Well, actually I came to see you Miss Jones but I’m happily surprised to find you like that. Bobby told me he’s spied on you touching yourself before» she said. «What, what! Bobby told you what!!» I blurted in utter humiliation. «Yes Miss Jones, Bobby tells me everything. It’s real easy to have him confess when I’m sucking on his cock» she simply added. «You’re doing what to my son?» I asked angrily now. «I’m tutoring him in math and in life Miss Jones. Don’t you like how Bobby is behaving these days? He’s such a darling when he puts his mind to something. He just needs a little motivation» she replied as she placed one soft hand on my thigh and caressed it. I was at a loss for words from both her totally unashamed sexuality and he soft touch. «Why did you stop Miss Jones? It’s normal to touch yourself when you feel the need» she quietly said and then took my hand and guided it until it was under my bikini again. «Could I watch please? You are so gorgeous, I was attracted to you the moment I saw you. No wonder Bobby is so pretty» she politely asked.
I should had been covering myself with my towel and running inside the house screaming but itself I found my hand fingers moving under my bikini bottoms, rubbing again on my swollen pussy. Nikki gently laid down beside me on the chair, he mouth inches from my ear. He body felt like a burning ember against me, heightening my already excited libido. She started whispering to me as I kept touching myself, her lips grazing my ear as she did. «You are so pretty like that Miss Jones. Don’t stop please, I was to feel you cum beside me. Bobby says he thinks you saw him masturbate the other day. Did you Miss Jones? Did you see your beautiful son jerk his hard cock until he came? He shoots a lot of cum does’nt he? I can barely swallow it all!» That was too much for me and my body gave up with a thundering eruption of pleasure! I managed not to scream to alert the neighbours but the orgasm was like nothing before. My little bikini bottoms were soaked right away. Nikki took my hand back and brought it to her mouth. She sensually sucked every one of my fingers while making «yummy» sounds then just said: «I’ll be back tomorrow at the same time» and she got up, looked me over hungrily while smiling and left!
