We asked 54-year-old Lena Lewis what turns her on, and she said, "Oh, lots of things! Watching porn. Not my own, of course. Getting tied up and getting a little spanking. Thinking about the hot sex I'm about to have with a young man. I don't think I'm ever not horny anymore."

She's horny in these photos, her first of four postings this week at 50PlusMILFs.com (solo video tomorrow, XXX photos Wednesday, XXX video Thursday. Maybe that's because this big-titted German babe is thinking about her upcoming scene with two young studs, in which she's going to get DP'd.

Lena said modeling for 50PlusMILFs.com has changed her in very good ways.

"It's made me more eager to explore sex in different variations. Now I'm doing things I might not have done before, like anal sex. Before, I wasn't that into anal sex. I would only have it with a partner who I loved and totally trusted, but now I've learned to like it as a regular part of sex. And doing those scenes taught me how to get aroused easily."

Call this scene a warmup for what's to come. Lena's going to do something she's never done before. At least on-camera.
