"Good morning, big brother..." The next morning after a night of drinking, my sister is naked next to me! "Your sex is pretty intense... Want to do it again?" I don't remember anything, but she says, "I think I got creampied for the first time?" I try to deny it, but it seems I must have creampied her while drunk. My sister, who usually looks down on me, suddenly starts begging for more creampies... Until my girlfriend comes back from her stay, I'm going to fuck her relentlessly. This is the creampie life of siblings with incredible compatibility.
