One day, knowing the call from the back yard was bound to be coming soon, I stroked my cock and kept myself on the verge of orgasm until Terri yelled for me. She was lying face down on the chaise, wearing only a small, too small, bikini bottom. I stood over her, fumbling with oil bottle so she could hear me, but with one hand I was stroking my aching cock. I put one foot on each side of lounge, straddling Terri’s ass while stroking my cock. I was so close to orgasm now, and I poured a small amount of oil onto her back just as my cock began to throb. I ejaculated several thick ropes of semen straight onto my step mother’s bare back.
Terri let out a little “ooooooo” then said “you warmed that up for me, nice.”
I stood over her, cock in hand, surveying what I had done to her body, and enjoying my dirty work.
I quickly stuffed my cock back into my shorts and leaned over and began massaging my cum into her skin while listening her say, “mmmmm, that feels so good.”
This became a regular part of my week during that first summer. As time went on I even found myself pushing more limits. I would let my hand linger on Terri’s lower ass, and even let my fingers brush against her pussy while oiling her inner thighs. Once in a while I would catch her taking a quick breath when I would lightly drag my thumb up the crotch of her bikini, and I could tell she was enjoying the attention of a man’s hands on her body.
As the summer went on, I even began oiling her neck and shoulders from the head of her chaise lounge. My hard cock bulging in my shorts, resting against my step mother’s head, and sometimes even against her face, although covered by her t-shirt. My thoughts became filled with how to get my cock into Terri’s mouth.
Little did I know at that time that I would soon cum in her pussy, and up her ass, before she ever sucked my cock.
