I returned the favor with her panties. We each began to stroke the other’s sex organ, each of us feeling the other’s excitement. I pulled her off ...rom on top of me, and gently placed her on her back. I kissed her, which she returned with such a passion. I looked into her eyes, as if asking her if she was sure about this. She looked back at me, tears in her eyes, and nodded ever so slightly. I slowly sunk into her. All the way to the hilt until I was buried inside her. We didn’t move, we just. They’d grown.If I had to guess, I’d say I was an F-cup, but I was in completely unknown territory here. I could have been a G, H ... do they even make “H” cup? I’d spent the first eighteen years of my life as an A, I’d never expected to have to know anything about the larger sizes.What’s more, they seemed to be completely defying gravity. A chest as large as mine, you’d expect a bit of sag ... anything this large that stood up proudly would look fake, but somehow my breasts managed to be large,. She whispers in my ear "Fuck me."She turns around, I take off her leggings and underwear and see her soaking wet pussy. She grabs my cock, places it at her pussy entrance and pushes back on me. I slide in with a slight pop into her. She moans louder this time. I grab her hips, steady her against the aisle and start to slowly fuck her. Making sure that on every thrust in I go in all the way. I fuck her like that for a few minutes, watching my cock glistening with her juices, her ass cheeks. Do you want another brother or sister this time?" I think another sister would be great," Ken said with a grin, "but I don't really care either way, I just like the idea that you and Uncle Ben are still making babies." Well I'm glad you're happy about it," Gwen said with a smile before she turned to look at the other children in the room, "but I want you all to remember that you can't say anything about who your father is - remember?" Yes mother," all her children said with an exasperated sigh..
