I often go to her house to play, and there's always a carefree sister without a bra. Her cleavage is visible, and from under her arms, you can catch glimpses of her ample breasts... Every time I'm at a loss for what to do, but recently when my girlfriend won't let me have sex, I can't help but look at her sister's exposed cleavage. I just want to touch it... Her sister's huge breasts are right in front of me, and lust overpowers reason! I can't stop getting hard in this loose, see-through loungewear showing off cleavage! There's no man alive who could resist these massive tits. I'm all over them, squeezing and bouncing them, indulging in a blowjob marathon that I can't have with my girlfriend. Even though she's right next to me, my reason has flown out the window!
