Saved by the bell

My mind was going insane, spinning to try to find an answer. Did the spray wash off in the shower when I was balls-deep in my sister? Did it have a limited time of effect? Fuck! Rach is standing there, looking at me like a deer in the headlights, naked as fuck and between my sister, the fact that I just fucked my sister full of three loads of cum, and the fact that I was scared as hell, my cock came to full attention. I was about to open my mouth to ask what she meant, when the bell rang by the door.

My sister, obviously feeling better after the showers and the water...and the fucking...sauntered over to answer it, her pussy winking at me as her legs swayed. She moved past me and slid her fingers over my cock, making me shudder.

"This isn't normal, brother," she almost sang, "nope, nope, nope," she added and bent over to talk, showing me her ass and pussy between her slightly gaped thighs and I watched as my creampie started flowing out of her in a long, slow, continuous thin streaming drop. She leaned down and put her finger on the button as the buzzer sounded again. "I shouldn't want to fuck my brother. You did something to make me want to fuck you," she said and then pushed the intercom button without so much as a pause, "Hey, who is it?" I watched my sister's ass wiggle while we waited, my iron cock ready to strike.

"Kids, I'm going to be home shortly," mom's voice came through the speaker. I moved behind my sister and slid my hands over her hips and she widened her stance, spreading her creampie filled cunt for me. If anything it just started flowing faster.

"Mmmm, kay," Rach purred into the intercom. I ran my cock up and down her molten slit and she pressed back against me.

"You sound like you're doing better," mom's voice said again. She shifted and my cock sank into her to the hilt.

"Fuck me," she said and we both noticed at the same time she was pushing the intercom. "Fuck me," she said again. "I don't know what I drank, but, mmm, my shower was, mmm, fucking amazing," Rachel said into the intercom as I started fucking her. While she was talking to our mother. She couldn't hold back and her finger slipped off the button.

"Watch that language, young lady!" came mom's voice over the intercom.

"Fuck! Fuck! Fuck! Fuck!" Rachel said each time I bottomed out, fucking her from behind. "Fuck me, brother! Then you've got some 'splainin to do!"

"Well, make sure your brother takes care of you, I'm cumming home after stopping at Desha's store," mom said and then clicked off.

"Holy fuck!" Rachel said as she came all over me, her pussy clenching down on my rod, almost making me cum for the fourth time. "Jesus fucking Christ!" she screams loud enough to be heard outside the apartment. "FUCK!" she screamed again and I flooded her cunt with a fourth load of baby batter while her spasming pussy milked me into her womb.
