backtomrsb steps up to the challenge of a messy gunging session at Gungemaster UK's. A kinky lady she's never engaged in messy play before, but is keen to adventure and experiment, so gungemasteruk has devised a Challenge for her and gungemistressuk to participate in a fun game, the wamination of Backtomrs B.

There's cards to choose from, one is a body part, the other is a substance, ranging from gunge/slime of different colours to custard, porridge and beans.

Dressed in matching boobless, crotchless outfits they step into the paddling pool as gungemasteruk doles out the messy substances. There's plenty of boobs, ass and pussy shots, clean and covered in mess. Along with a fair ole amount of head dunking!

Once the girls are suitably messed up they're both given their vibrators to lie-back and let off a little steam with some rabbit action on their clits. During which gungemasteruk continues to pour various messy substances over them.

Who cums first? Well you'll have to buy the download to find out. But once both girls have cum it's gungemasteruk's turn for some fun with a blow job from gungemistressuk.

Finally the girls get to gunge each other!
