The popular series that targets the 'Spence Mammary Gland,' a woman's new secret erogenous zone, features the healthy and curvy Sari Kosaka. This 'G-spot of the breasts' is stimulated deep inside with specialized devices, pushing her to reach her first-ever breast-induced orgasm. From nipple teasing and toy-induced squirts to hyper-sensitive breast jobs, witness the total development of her youthful, firm breasts as she writhes in pure ecstasy.










Sari Kosaka is one of my favorite actresses, and as expected from the Spence mammary gland development series, they really go to town on her massive breasts in various scenarios. Her firm, erect nipples looked so cute. It takes some serious technique to make her squirt just by obsessively focusing on her tits. Seeing her completely drained and limp at the end, I was impressed by how much eroticism they managed to sustain until the very last moment.
I've watched a few in this series, but the idea that a woman can reach climax from a handjob/breast job is just pushing the fantasy too far. Are they still doing that trope where she faints at the end? I haven't seen this specific one with Ms. Kosaka yet, but I think it's because of works like this that there are more clueless virgins out there and the actresses end up being exploited.
*Recently, OPPAI has continued to release fantasy creampies that use big-breasted actresses but don't even let the actors ejaculate, making me hesitant to purchase them. This work was also very disappointing because of the F creampie finish that ruined the material of Sara Kosaka.
