"we're siblings... so it's only going as far as rubbing." for 10 years, my kind and gentle older sister has been helping me with my sexual needs, even though i'm a shut-in neet, on the condition that it's only going as far as 'rubbing against her bare skin'. one day, when i inserted the tip of my penis 2cm into her wet pussy, she didn't say anything... so i ejaculated inside her, incestuous sex. amamiya kanan
