A very arrogant female colleague of the same year at the company missed the last train and stayed at my place. 'Lend me some loungewear' she demanded, and reluctantly I lent her some clothes, but they didn't fit, exposing her cleavage and panties! Sleeping in the same futon, her breasts and butt kept touching me, leading to an unexpected erection! I thought she would definitely get angry, but my colleague, who usually acts tough, suddenly became aroused and, while shyly asking for my dick, showed her true tsundere nature, and it became unstoppable! Completely lost in the moment, we kept going at it, repeatedly cumming inside her!
