Never pass up an opportunity to be nice to an older woman you never know what might happen.
If ya gonna shag ya mates mam do her from behind so she doesn’t see you grinning too much.
If a friends asks if you fancy his mrs say yes
Another tip is if you are gonna bang your mates lass after you cum try to avoid eye contact or kissing right after. Don’t be a dick and just leave hugging is ok but wait a while to kiss her. From my experience that post nut kiss or eye contact can lead to feelings
