I was really proud of myself on how long I'd gone with out cumming. I looked and saw Sharon's eyes were closed as I was nearing my orgasm."Oh, baby- o... baby — you feel so good in your momma's pussy!"I heard giggling, turned and saw the girls watching us. That got me ready to blow as I sped up and filled my beautiful and outstanding mother with my boy juice. I motioned the girls to leave, and they did blowing me a kiss — as I gave Sharon the last spurt of my jism."Did I hear the girls?" she. I lower your foot and change hands on the vibrator as I lift your right foot to my mouth. I slide the machine out of you and place it back on your clit where I begin to massage the swollen button. You are now looking at me trying to time the moment I place your toe into my mouth. I look you in your beautiful eyes as I lick your toe all around. The feeling forces your eyes close and head back on the pillow. Right then, I engulf your toe into my hot mouth and begin suck forcefully. You shiver. She closed the door, locked it and heaved a sigh.Nervously, she stripped off her top and looked at her budding tits in the mirror. "God, I wish they were big like Mommy's," she moaned. She caressed her sizzling flesh. Tiny goose bumps dotted her smooth silky skin.Her fingers trembled. She tore at her shorts, shoving them down over her slim girlish hips. With her heart pounding, she stared at her lithe figure, silky blonde pussy mound, and small sensitive tits.She skimmed her small trembling. Obviously the thought had crossed my mind that she might not be mine, but those thoughts were quickly dispelled the moment I clapped eyes on her. It could have been a young Julia standing there.Disengaging herself from my two daughters, Mackenzie took Joseph's hand and he led her over to me. I could see that she looked even more nervous than poor Joe had done."I'm sure your half-sisters have told you that I don't bite," I said, smiling and holding my arms out to her. Well, what else could I.
