Saturday night phone rings. Missed last train, let me crash~ From girlfriend's sis 'Yu'. Was gonna say no, doorbell rings. She barges in. Looks tipsy, super touchy, grinding on me nonstop. Top loose, huge tits rubbing against me. Like she's begging to fuck, shoving her juicy boobs on me. If GF finds out... Hey, you're touching me. Hmm~ On purpose. Can't hold back, gonna pound her dripping pussy all night long!
