the hj mod would be perfect if it worked on the other movement
RTFM
It does work for other sexual positions, but
the result may not be very sexy or convincing.
Auto Mode does not directly "move" the characters along their tweens. Instead, it changes their target positions. The game logic attempts to move the characters towards the new target position, in the same way that it would respond to a change in target position based on
movement of the player's mouse pointer. There are
limits on character-movement speed (for simulationist/realism reasons); character movement is subject to acceleration and can be inhibited by collisions and pseudo-friction effects.
When Auto Mode is active, the game chooses a specific
penetration depth and then oscillates the target position around this depth via a sine-wave function. The result is a "thrusting" effect (for face-fuck mode), "sucking" effect (for blowjob), or "stroking" effect (for handjob). The game occasionally changes the penetration depth (for realism/diversity/whatever), and incorporates some aspects of the girl's psychology. It will tend to penetrate less deeply in "Soft" mode than in "Hard" mode. It will occasionally pull out completely to allow an opportunity for dialogue (or simply to let the girl catch her breath).
The handjob accelerator mod alters the sine-wave function so that the oscillations proceed more quickly (e.g. 2 strokes per second instead of 1 stroke per second).
Imagine that the mod tells the guy
"pull out completely, then jam your dick all the way in, then pull out completely and repeat the process. Complete one cycle per second." It may not be
possible for the guy to actually move that fast -- it depends on the length of the tween, the size of his dick, and the bodycontact resistance factors. If he
can't keep pace, then he'll fall behind the changes in target position. He'll end up with his dick halfway into the girl, making shallow in-and-out motions instead of the vigorous fucking that you wanted.
Alternatively - you might want the guy to pull out
almost all the way before thrusting in to the hilt. Instead, he pulls out
completely before thrusting back in. When sped up to 3x speed, this may look implausible - or even
painful. The mod isn't especially clever about anatomy. The difference between
"almost pulls out during each thrust" and
"actually pulls out during each thrust" will depend on the configuration of the position in Animtools, the distance between the characters, the girl's bodySize, the length of his dick, etc...
Additionally, the blowjob Auto Modes include several
scripted movement patterns (such as
"make eye contact, then look at his dick and slowly swallow it all the way to the hilt, then make eye contact again" or
"wince, pull off completely, and complain that he is hurting her"). Since the vaginal/anal sex positions reuse the blowjob motion patterns, one of these scripted actions may occur suddenly. The scripted actions do not use the sine-wave function (hence: they
aren't accelerated by the mod), so they'll tend to interrupt your slam-fucking scenario with an unexpected lull.
Please be aware that the faster movement speed produced by the mod will cause faster increase in the Pleasure stat for the male character. You may be disappointed to find that your guy has lousy stamina. This can be tweaked via
ejacPleasure parameter in your Settings.txt file.
tl;dr ...
experiment with the handjobAccelerator mod. Make note of its deficiencies. Keep track of any "missing" features which might enhance your gameplay experience. Then post a
Loader Request thread asking for a patch (or a brand-new mod) which addresses your needs. If your requests are reasonable then I might grant them. If you haven't put any thought into the request (or if you persistently refuse to use your Shift key) then I'll ignore it.
