The wife is away for a couple of days and I have time to twiddle my thumbs (/penis), and I want to have a couple of ‘solo sessions’ that are a bit different than my usual routine.
What are your favourite things to do / tips to have an extra special wank?
Prostate massager. Have an intense orgasm.
I have to second the recommendation of a prostate massager.
Find some nice videos, prostate massager and a stroker
I can come hands free with a vibrator strapped to my penis. That might be worth trying.
This is my favourite subject. Some things I like to do:
•edge
•ruined orgasm
•dress up and take pictures/videos
•anal play
•self roleplay. I like to set scenes in my head with my toys/outfits.
•multiple orgasms throughout the day. Go ahead and set that PB for wanks in a day!
Have a wonderful day 
Porn plus some nice anal toys to accompany usually is a good start 
Save it up until your wife comes home, and then share it with her!
A friend of mine used to put some of his wife’s silky tights on…get out his wife’s wand and rub his hands over his silky clad erection and thighs then run the wand up and down his erection whilst blindfolded and smelling his wife’s used knickers…
This is giving me ideas for my Thursday Wank Club 
I wish I enjoyed anal… I just don’t. Never tried a prostate massager though, so that may be a game changer
First and last are regular features!
That’s such a flex!
Days*
Thanks for the suggestions!!
Impossible
Damn. That’s so specific considering he’s your friend
There’s a club? Can I join? Is there a membership fee?
He was a FWB but he’s still my friend now…
Use a butt plug, you won’t regret it
When my wife’s away I’m just more likely to bust out a prostate massager or plug to play with, as well as strokers and cock rings.
I also mix up the time of day - I don’t normally masturbate midday as I’m saving myself for her every day, but when she’s gone I’m more likely to start my day with a wank or squeeze one into the afternoon and take the edge off before the kids get home from school.
I also enjoy sending her naughty pictures and texts through the day and process - dripping precum, a spent load on my chest, naked selfies, etc.
