Seeing as you have few household objects, let's try with fingers to stretch you out. See how many fingers you can fit in your pussy. Use both hands alternatively. So one finger from one hand, then one from the other, etc.

Once you have reached your max, pull your hands apart as much as you can, stretching yourself open. Hold in that position for two minutes.

Goals:

Get so loose to be able to take several cocks in all holes at one time (I understand this is a long shot but given the circumstances, I think it can be achieved).

I'm fascinated by hucows...to be able to have humongous nipples that are always swollen and plump, ready to be sucked and chewed on...I'm interested in inducing lactation as well so any tips on that are well appreciated.

I get turned on by animal play, piggie, cows, dogs, whatever it may be...
My favorite channels on pornhub are: sexandsubmission, publicdisgrace, hardcoregangbangs (should give you an idea of what I'm into) ;)

Please make me into the loose whore I want to be.

Send me a message on for my kik username. Also please feel free to send me links to videos to watch, it'll keep me busy!

Will reply to all other messages shortly.

Stretching is a bit difficult because you need fairly long-term repeated sucking and not just squeezing like you'd get from a lot of things. Though it's a bit tempting to see how the brush on your vacuum affect your nipples as a bit of a punishment :D. Not having the vacuum makes it harder. Some people will use modified 20-30mL syringes if you can get your hands on those (most pharmacies sell them cheap) and they create a fantastic vacuum on nipples.

For some women, regular and repeated sucking on their nipples will eventually induce lactation. Are you able to comfortably suck on your nipples? If so, I'd say to try and make a habit out of sucking on them regularly and repeatedly throughout your day, that may help you get towards your hucow fantasy. You can you're a 36C so that should probably be pretty reachable I'd think- all you have to do is get in the idle habit of whenever you're alone you just strongly suck on each nipple for a few minutes.

It's a long shot, but you don't happen to have access to a 3D printer, do you?

Managed to order a vacuum during the quarantine so can do the vacuum trick now, however also tempted by the 30ml syringes since you said they create a fantastic vacuum (plus their more portable).

Not able to suck on my nipples, my tongue tip reaches them but can't bite them or suck on them.

And definitely no 3D printer.

Will reply to others soon, as well as what else I've done

Bum art.
The idea is to slide a marker into your arse, nib exposed and pointing out. Then squat over some paper and draw something. Using different colours for more interesting pictures.
Maybe different colours at the same time. How many colours can you use at same time
Then post the pictures here (of your drawing), pic/vid of you doing it, or a full write up, and attach your drawing to your window
