These poses are currently being sold only at Bewbapalooza. The round starts May 20th 2015 and lasts for 3 weeks. This is considered a minipack and costs L$125. They are boob friendly depending on how big a person's chest is. At bewbapalooza, there are demos to check it out and see if it works for what you need.
These poses are my full exclusive item for Bewbapalooza. Meaning that, after this round is over, they will not be found in the store. The set is made with bigger breasts in mind, and only costs L$50. The poses will work for smaller breasts as well, but gives space for bigger boobs to kneel as much as 'possible'.
