My sister, who loves me too much, seduced me after our bath at home broke down, leading us to stay together unexpectedly. She has been teasing me with her huge tits since we lived under the same roof... "It's okay if mom knows that you touched my boobs while I was sleeping?" she asked. I gave in and promised not to tell anyone as long as she had sex with me. We engaged in passionate love-making filled with fondling of her voluptuous breasts.
