The super tight K2MAN CORE series is here with its third installment! The Japanese A-ONE brand has designed this onahole with an undeveloped anus, specifically for gay men who love anal sex. The undeveloped anus provides an extremely strong and tight feeling, completely enveloping and compressing the penis for an intense sensation of 100% pressure stimulation! From the entrance to the depths, the onahole provides a tight and firm sensation similar to the anal sphincter, with high elasticity and contraction!
