Rickie steers a rather bewildered Beckie to you, and you pull her mouth down to your breast, which seems way larger than normal [tho your brain doesn't seem to be working on all gears, and what little functioning it can do is focused on Beckie, so you aren't going to insist anything is anything.]
Beckie starts to suckle and you clutch your not-at-all little "daughter" with all your strength, while barely touching her. You have no idea how you can manage both at once, and don't care. You are going to cleave to her like iron, and as soft as silk.
Indeed, a lot of unfamiliar ideas are taking strong residence in your mind. Why are you so eager to love her all of a sudden? Maybe she wasn't a bitter enemy earlier, but she certainly was no friend. And now she is the center of your life and you would do anything for her? That's weird.
It's also exactly the way you feel. However wrong it might logically be, it feels entirely right. You will do anything for her, anything at .... For some reason you suddenly think of homework. You got quite a bit behind while you were in Beckie's womb, and now Beckie is way behind too. Maybe you should help her... But the purpose of homework is to improve her skills, not yours. So her homework is something you won't do for her. In fact, you will be driving her to it instead, just like she did with you.
Of course, that doesn't rule out a little help...

However, now you are distracted by Richie, who is about to molest your innocent daughter. [The fact they have banged dozens of time doesn't stop you from considering her a virgin, nor from thinking Richie is taking advantage of her. Besides...] "Stop! That's no way to treat your daughter!"

Rickie does pause, long enough to ask Beckie "Now you don't think of me as your dad, do you?" His hands explore intimate areas of her as he asks.

Beckie answers both verbally and physically, and both favorably. "Not at all," as she spreads her legs to allow Rickie easier access, "But now that you mention it, I'm not too thrilled by the idea of you seducing my little girl here. I suppose you are her father in a way, but I'm more scared you will do things she is too young to be doing."

"Hey! I'm as old as you are." you protest. "And you have been doing all sorts of stuff."

"You are two weeks younger, Baby." Beckie responds. "I checked."

"And you, Beckie, have been having fun with me for a good deal more than two weeks." Rickie breaks in. "So she is old enough if you are. And you have already said you are old enough for this..." And with that, he slides into her most sensitive spot.

You try to protest, but with Beckie lying on you, it's pretty hard to get out anything coherent, much less effective. Instead it is Beckie who answers, after a pleased gasp, "well....you be good to her. Make her happy. Don't go chasing other women...don't...Oooo..." And Beckie collapses in joy.

Richie finishes a stroke or two later, and starts to shove her off you in order to start on you, until you say "No! You are not to treat my darling as just used goods. You treat her properly."

Richie responds with a nice kiss for Beckie, who is still not awake enough to appreciate it, and then gently lifts her and carries her to the other bed. Then he is bounding back to you. He is thrusting into you immediately, and almost as quickly exploding. However he does not stop and instead continues to stimulate you as you too recite a lists of orders on how he is to treat your little child. And like Beckie, you are overwhelmed by emotion well before you can finish the list.
Well, you covered the basics...
