Not hot...I mean shit, both on the Dom here for not keeping his sub quiet, and on the sub for (presumably, if the neighbours can hear it) making more noise over a bit of slapping and sex than people do during invasive medical procedures. tsk tsk...
If Rangrz and Ms.G where the neighbours, we'd come over there and gag both of ya and fuck ya til you loved us.
On my end: I agree with the poster who says discuss it, obtain consent, safe words, etc.
Best answer as usual this and dont forget some sex toys!
Also: Avoid cliche tripe like "slut" "whore" "bitch" "who's your daddy?" etc. It makes one sound borderline retarded.
Use finess too! Forceful and rough and sloppy is pretty whack. Be forceful, but with precision and care. Also, try to substitute "command presence" for "forceful" whenever possible, and substitute "Leadership" for "command presence" whenever that is possible. Which should be 80% of the time or more.
Forceful would be pinning her down, command presence would be very sternly and directly telling her to get on her back with her knees up and legs spread. Leadership would be hinting it to her or asking her to do it, in a cheerful manner. If you do it right, she'll do it with a smile on her face and will feel more like she is a really hot girl who a guy really wants to get with and still feel respected. The communication involved also makes it more intellectually stimulating. Just pinning her down would be a) more like she's a warm squishy hole than a person b) it's pretty basic. I guess that's not a problem if you *are* just basic, mind you.
