We sucked each other for the next 10 minutes or so, neither one of us close to cumming yet. Then she dismounted me, turned around, and straddled my co...k, and guided it inside her. She plunged down on my cock, leaned down, crushing those great tits into my chest, and said, get ready for a fabulous fuck baby.She sat back up, put her hands on my chest and said, god I love this cock in me. She started grinding and going up and down on me. Her pussy was so hot and tight. She asked if I liked her. "I have a Doctorate Penelope. It?s in my nature to study andinvestigate. I know who you are and what you?ve done, it?s all in thepublic domain," Penelope explained."What?s in the public domain isn?t everything," Penelope whispered."I know you?ve been through a lot and that your life has been difficultbut you seem so together." Melissa absentmindedly stroked Penelope?shand which was still resting on her shoulder."See. I?m proof that you can overcome your demons." Penelope gave hera wry. I asked her how it felt.

Nikki was obviously not going to get used to a decent-lengthed but wide cock sliding in and out of her in one day, which is almost surely all I had with her since I was going back to school soon. If this was how she was going roll from here on out, she was going to need to learn to take a cock. I decided I would be the teacher. I would. And, as young girls do, we started trying to figure out what we could do to get things moving. I don't remember which one of us came up with the idea, but we finally decided that maybe massaging my chest would help. So, Liz started using some lotion and rubbing my breasts."Looking back, I would have to say that it didn't seem to have any effect on developing my tits, but it sure as hell got ME going. I discovered that I really loved having my nipples played with, and it gave me my first orgasm..
