(Editor note: I kind of wrote this as an ending to the series, but I like the characters. Might make more with these characters later.)
A few months later...
Things have changed a bit since that night a few months ago. When Emily And Sarah broke up and Sarah joined into a relationship with myself and Ellen, the house really changed. I had not had sex with Ellen's mom Maria or her sister Emily ever since. None of us have. Our relationship stayed internal, I feel it's because we had everything we needed.
Emily's experimenting was just beginning though. Every other week it felt like Emily had a new boyfriend. This week she was with a guy named Oliver. I could hear Emily almost screaming in pain when they had sex. It didn't take long to find out why. Olive walked from Emily's room to the washroom and I was walking past. Oliver was naked and along with that his monster 12 inch cock. I won't lie, it was quite impressive. I don't even know how someone as small as Emily could take something like that.
A few days later I went to Maria's room to talk to her about something. I get to the door and hear Emily inside.
"Come on mom, take his massive cock" Emily said. I cracked the door open to see inside.
"If I pushed you kids out he can push that thing in" Maria said.
I saw Oliver's massive cock half way inside Maria. Emily was lying next to her rubbing her mothers clit. Emily started to kiss her mom, still rubbing her clit.
"Give her more." Emilys said to Oliver, still kissing her mother to keep her screams and moans down.
"I'll give her all she can take" Oliver said fucking her a couple inches deeper.
"Okay Now do me!" Emily said, shifting her body around and opening her legs.
"I think Maria still wants more." Oliver said, ignoring Emily.
