I've been trying to cum inside while she is in sleep and clean up before she wakes up. Here is what I've found out.
- Soft touch skill is a must
- Some positions require less clothing to be taken off, thus less chance of detection
- No need to take panties off as long as short pants are off (need to spread legs for missionary)
- (could be wrong) Strangely, she seems to get upset if she wakes up before cumming, but not after
- Moving inside her has a big impact on the wake meter, so it's safer to insert shallow and fap inside
- Clean up means just redressing her, no need to wipe off to avoid detection in the next morning
I once managed to cum inside by fucking instead of fapping, but cumming inside appears to have high 'wake factor' in and of itself. Ended up waking her, but to my surprise she asked for more instead of getting mad
