When I go to stay at her house, it seems she always sleeps with her sister because of her lonely personality, and for some reason, we end up sleeping in a triangular formation with three of us... Then, right in front of my eyes is her sister's surprisingly enormous breasts! I really like her, but I can't resist being tempted by such a sister! Unlike her, who only allows sex with a condom, her sister is okay with raw sex! And even allows creampie! With her right beside me, the raw sensation feels too good, and I can't stop the piston motion!
