As my orgasm started to really build past the point where I could delay it I felt a hard finger, or two, slip wetly inside me. She slipped them past m...y labia and deep inside me, my orgasm was now making me writhe and buck, she pumped her fingers inside me and then turned her hand upside down so that the ends of her fingers were facing upwards. As she fucked me with her hand I could feel her fingers sliding over my g-spot every time they ran inside me. This added buzz coupled with her tongue. I rose up my left leg over your right leg, giving you an access to my inner thigh. You stroked my legs, and pushing further under my mini-skirt. Your fingers reached my laced thongs and slide it sideways. "You're soaking wet my dear. Is it all because of the caffeine?" You spoke while biting my ear. "No babe, it’s all because I was thinking about you." I moaned as you play with my slit. Your fingers started moving up and down, and in circles. You removed your hands from my mound and you.

His head hit her teeth. It caused her to become flustered and freeze. Her son's cock had hit her mouth, almost entering it. As Billy swayed. I started to stick my tongue directly inside her, thinking this was what she wanted."Oooohhh", she breathed, "that is so good. Don't stop. Oh yeah, lick my pussy. Ohh, so fucking good." Somehow, I kept my free hand away from my cock, or I'd have shot again."Lick my clit now", Cindy instructed. I knew what a clit was, of course, but I needed her guidance to find it. Cindy's clit wasn't large, but it was engorged. I put my lips around it and started to suck."Tttsssss!" was sort of the sound she.
