My girlfriend's sister begs me to "practice licking"... I know it's wrong, but she licks and sucks me with her big tongue, and her blowjob gets better every day. Is it too good to be true? Anytime, anywhere, sneak away from her eyes and swallow her cum in a short affair! Sumire licks the cum off her palm and swallows it, swallows it in her mouth, swallows it on her tongue... Sumire is so erotic as she shows me the cum on her big tongue! Because of Sumire, I can't break up with my girlfriend...
