Option 2: Rachel, his sister!

I looked behind me, slowly still fucking Ria, and I saw... my sister! She was still wearing her school uniform, but one hand was deep in her skirt and rubbing herself off. Slowly, by the looks of it... And she unbuttoned her blouse enough to reach under it and her bra to grope her breast, too. "Rachel, I... You're supposed to be--"

"Please," she interrupted in a soft, husky tone. "Don't mind me... Keep pounding that 'innocent' girl, big brother." She smirked at the end, hinting at my sex. This was an unbelievable day I was having so far... After I finish my new deodorant, girls want me; Ria comes over, dances for me like a stripper and it leads to me making a woman out of her; and now my sister was watching and getting off on it?

"Daddy?" Ria asked for me. "Don't you want me?" Rachel echoed the question at me, pinching her clit and shuddering a little. At that moment, I lost myself and went on pounding Ria's pussy some more, and Rachel was just enjoying it all.

But suddenly, she said, "You kids have fun. I'll be upstairs if you need me..." she replied in a singsong voice, watching us until she couldn't anymore. I couldn't help but since she still had that naughty smile as she left. Not that it mattered because I kept my eyes on Ria, **** her some as I fuck her.

"You're mine now," I told her. "You'll do what I tell you. Got it?" She replies, 'Yes, Daddy.' So, I tested her. "You will think of me, taking you and ordering you whenever we're apart. Understand?" And she says the same reply: 'Yes, Daddy.' "Good girl. Cum for your Daddy." That was just what she needed. She began rubbing her pussy hard and fast, rolling her eyes back to get lost in her oncoming wave of pleasure.

"I'm cumming, Daddy!" she moaned in a slightly higher pitch, rubbing up and down as fast as she could. "I'm cumming! I'm cumming!" And that's when I pulled out of her cunt and stuffed my cock into her mouth, ready to erupt from the teasing and sex.

"Suck my cock!" I told her, and she moaned against it. That sent vibrations of pleasure throughout my body, and we both came at the same time! She made a bit of a mess on the couch, but she took every drop of semen I had, swallowing it in a few gulps. When I felt empty, I pulled out as Ria and I panted heavily. "Good girl..." Ria smiled at me and then laid down to rest. I couldn't just leave her like that, so I made some blankets out of the clothes she took off.
