“Mom, sit on my face,” I whimpered when she looked at me.
A huge smile appeared on her lips as she maneuvered into position. I thought she would just sit on my lips but instead she turned so she was facing Sherri and stayed on her knees. This left her pussy about an inch from my mouth forcing me to lift my head enough to run my tongue through her wet slit.
“Oh yessssss!” she hissed as I made the first pass.
Satisfied that eating mom would take my mind off the sensation of having my sister ride my cock I began to tongue her in earnest. I couldn’t tell what they were doing, mom’s succulent ass blocked my view, but if I had to guess judging by the sounds I was hearing I’d say they were kissing. Grabbing mom’s cheeks I parted them and ran the tip of my tongue over her rosebud. This garnered another moan from her. Mom must have been pretty primed, because in less than five minutes she was mashing her cunt on my lips and yelling for me to chew on her clit. When I did she began to shake and grind against my mouth erratically. Without warning I felt fluids gush from her cunt and cover my chin.
“I’mmmm cummmiiiiiiinnnnnnnngggggggg!” she screamed, then with one final quiver she rolled to the side and lay in a fetal position.
I didn’t have time to savor the view of mom’s leaking pussy just inches from my head because Sherri began to really pound down on my cock. Looking to where her cunt met my rod I saw that she had finally been able to take all of me inside her stretched twat. The look on her face was one of pure triumph. Unable to resist the temptation of fucking her silly I placed my arms around her and pulled her down on top of me. With her body resting on mine I lifted my knees, then planted my feet for leverage and began to hammer into her.
“Oh Shit! Oh Shit! Fuck me you bastard!” she screamed, her teeth sinking into my shoulder stifling her screams.
Faster and faster I plowed into her, her tits scraping against my chest as the force of my thrusts rocked her body. Sliding both hands down I cupped her ass and squeezed.
“Uuuuugggggggghhhhhhhhhhh fuck!” Sherri squealed as her orgasm exploded.
The feel of her cunt muscles rippling up and down the shaft of my throbbing cock, along with the sensations of her juices trickling onto my balls sent me over the edge. With a roar I jammed my cock as deep into her pussy as I could get it and flooded her love tunnel with spurt after spurt of my thick creamy spunk. When my cock finally stopped twitching my hands slipped from her sweaty ass and dropped to the floor. Sherri just lay limp on top of me as we both tried to catch our breaths.
