Option 1: Becky, his mom!

I couldn't believe my eyes... Mom was leaning right there, against the entrance between the living room and the hall. One hand groped her breast through her shirt, and the other was roughly rubbing between her legs. It was something to behold: when did she get back? How long was she watching us...? Speaking of us, Ria still kept rocking her body to want release, seemingly oblivious as to whoever was there. "Daddy..." she whined. "I want to be your girl." That snapped Mom out of her sexual trance, and she blushed heavily, straightening herself as I shushed Ria again.

"I-I-I'm so sorry!" Mom stuttered. She scampered upstairs in all her confusion, and my love was still **** for me to take her. I tried resisting to figure out what exactly happened, but Ria was making it difficult... So, I leaned down to her, covered her mouth, and went back to pounding her roughly.

"You're my girl now," I said quietly. "You do whatever I tell you, understand?" She nodded with a soft moan. "When you hear my voice, I want you to remember me as your Daddy, someone you listen to. Understand?" She nodded again. "And finally, whenever we're apart, I want you to think of me, your Daddy. And how you can please your Daddy. Understand?" She nodded almost frantically. "Now, cum for Daddy." She began rubbing her clit furiously, panting quickly and moaning under my hand to silence her. She moaned even faster as she reached her climax! She gave a prolonged moan as she still rubbed, erupting cum like a volcano of lust all over my dick. I quickly pulled out, stroking myself with the hand I quieted Ria with, panting, "Open your mouth... Swallow Daddy's cum." She wrapped her whole mouth around me, sucking me off with vigor and huffing through her nose. Finally, I shot my load in her wet hole, trying to keep my voice down as I groan my moan. When I felt empty, I pulled out and she flopped back down on the couch, licking her lips of some of the cum that slid out and down the side of her mouth. She curled into a ball and just closed her eyes: her virginity being taken and dancing for me must've tired her out.

I petted her head, telling her to sleep well, and made makeshift blankets over her with the stripped clothes she left behind. I then slid on my underwear and walked up the stairs to check on Mom and Rachel. When I got near the top, I heard a shower going. I wondered who was in there, but I went to look after my drunk sister.
