Part 3 of the series "Big Tit Tinder Sister" starring Sabrina -- My little sister let herself in unannounced while I was in the shower and scared the hell out of me when I got out. She's lucky I didn't walk out naked. She asked me to sit down and started telling me about her romantic woes again. She can't find any fellas on Tinder. I don't get it. If I wasn't her brother, I'd be all over her with those big old titties. I told her so, too. I admitted to thinking about her a lot since I took those nudes and ate her pussy the other day. She noticed my dick was hard under my towel, and, holy hell, she asked me to take it out. I was astonished with the look of joy on her face when she had my dick in front of her... and she started stroking it. It feels so fucking weird, but so, so good. She took those beautiful tits out for me, pressed them on me, and let me suck and play with them. She even jerked me off to completion. What a good little sister. I love her so much.
