((well 'stood' up made me think that she was 'standing' in a way on his bed. Since you didn't use 'off his bed', I assumed that she was still on his bed and facing his bed can be used even if she's still 'part' of what she's facing so the off his bed part that wasn't there confused me. so I thought differently sorry.
Also, I am sorry with the one liners but I got the feeling that some posts that you were doing were showing me that you weren't getting into this scene by cumming exactly when he prematured. so I thought that you wanted this scene to past by quickly ASAP in real life time.
He's just being selfish since he IS a prince and is enjoying the sex. She is going to leave, I only ask that he get to cum first a least...I'll repost now for a better one now that I understand clearly. I got upset at what you said because I thought that it was really BS for a girl not to enjoy it from behind but now I understand why you said that now that I understand your exact position so sorry.))
He did something that she didn't expect: while she held on to his wrist considering that there was nothing in front of her, he moved his hands under her thighs to lift her body up leaning against him forcing her hands on his head for balance as he moved in and out.
Honestly, he didn't think that he was this strong but it came so 'natural' for him to hold her like this. Of course he would soon get tired but the way how he entered her 'freely' like this, it made the sex needs much more demanding.
