So, what is it? Ah, yes. Size. I remember Erika used wonder about it although she never told me at first. Then, when we’d spent some time getting to know each other and progressing sexually, she really did take a keen interest for it. I was her first and it was a long working up process up to the point in which we could finally get it all in. Good sex ensued for both, much of it I think, stemming from the fact that neither of us actually knew what good sex was. Anyway, I had a single wooden bed and this bed had a low bedpost, with a rounded (look up bed part) at the top. I’d never thought of it much and if you’d ask me neither had she, but one day we were lying around naked and she got up, stood next to it, looked at me, put one foot on the bed and left the other one on the ground and positioned herself over the (look up bed part) and at first only pressed it against her pussy, then slowly started making little circular movements until she finally began lowering herself unto it. Yes, really. She made it nearly ¼ of the way down, looked at me with a mixture of pride and surprise and then got off. I was ready again. We had another round. I didn’t know then but that was the beginning of a quest for her. I think that she wanted and needed to know exactly how much she could take into her. A question was born and an answer for it was needed.
