“You’re going to have to, Jack, if you want me to let you cum in my mouth this morning,” she teases. She has her finger back inside her pussy. She pulls it out and starts rubbing my asshole with it again. She rubs all around the hole, and then pushes just the tip of her finger inside my ass at exactly the same moment that she eases her lips completely down my shaft.
“Oh fuck! Lisa, that is fucking amazing!” I moan, trying not to move.
The end of my cock is in her throat and her lips are pushed against my pubic hair. She holds me there, licking my cock with her tongue and fingering my asshole, then pulls off and takes a deep breath. She immediately slides her mouth back down my cock and pushes her finger a little farther inside my ass.
I’m going nuts watching my sister deep throat me, while fingering my ass. I’m concentrating on keeping my body still while Lisa, looking directly in my eyes, continues deep throating my throbbing hard cock. With her hand still playing with my balls, she must feel them tighten, as I get ready to cum. She pulls her lips halfway up my shaft, continues licking the underside of my cock and pushes her finger all the way in my asshole just as I shoot my load. She’s sliding her finger in and out of my ass, and swallowing my cum, as I continue shooting load after load into her warm, wet mouth.
“Fuck! You are amazing! That was absolutely a mind-blowing fucking blowjob, Lisa!” I’m yelling as she cleans the last bits of cum off my cock with her tongue. Her finger is still buried deep inside my asshole as she pulls her face away from my cock and licks her lips.
“Mmmmm that was a good breakfast,” she says as she eases her finger out of my ass. “Did you enjoy it, Jack? I did a little more homework. I was thinking maybe extra credit. What do you think?”
“Extra fucking credit is right! Deep throating and fingering my ass! I’ve never felt anything even close to this before. Lie down, Lisa, let me see if I can do half as well with my breakfast.”
“Wait, Jack. Let’s go find the vibrator! I want you to experiment with it on me.” Lisa jumps off the bed and runs naked into Mom’s room. I follow her, staring at her tight round ass, while she searches through Mom’s dresser drawers.
“Try her underwear drawer,” I tell her, standing in the doorway, enjoying the view of my naked sister rummaging around in Mom’s dresser. Her nipples are hard and her tits are bouncing, as she moves around looking for the vibrator. “That seems the most likely place.” Lisa opens Mom’s underwear drawer and pushes her bras and panties aside to look underneath them.
“Here, I’ve got it!” Lisa holds up the nine-inch pink vibrator that we saw Mom use yesterday. “Wait. What’s this?” Lisa asks, as she pulls a small plastic oval out of the drawer. It has a wire attached to it that runs to a switch. The oval is about an inch long and looks like a little egg. The wire is about two feet long and the switch is a small plastic push button. Lisa pushes the button and the egg starts to vibrate.
