I did not care if she felt my erection! I wanted her to!!!She finally ducked her head and in a breathy manner told me to stop or she was going to have...to fuck me now. I was not going to object to that! But the realization that we were just feet away from both of our grandmothers finally caught traction in my mind and I kissed her forehead and agreed. We went to the sideboard and she stooped down to get some of “the good plates” out and was eye level with my bulge. She looked up at me and then. She performed her version of magic and between one blink and the next, went from dressed to naked. I’d seen her undressed many times over the last few days, but this was the first time I’d seen her naked.She turned to face me, “Please, Ben, make love to me. I know I don’t deserve you, but I’ve missed that amazing feeling I get when you possess me.”She looked at me with a mix of desire and hopefulness. “Please, Ben,” she said again.I can’t help it; I’m a sucker for a beautiful naked woman in my. Short little mini skirt that is more than revealing, a tight tube top pushing her round fleshy breasts awkwardly upwards and almost falling out. Her make-up is dark and she is walking on heels that resemble stilts. I take a look at her succulent neckline and there is the collar that I placed on her 3 months ago, proudly owning the body that belongs to me now. I answer the door, not allowing her entry as yet. She greets as she has been taught, “Good afternoon Sir”. She does the smallest curtsey. I put the drinks down and jumped in the pool. A few minutes later Sarah came back out and dove into the water. I was at the far end in about 4 to 5 feet of water, she swam over to me and stood up facing me. She smiled and said "Did you do that on purpose so you could see my tits?" I said "No, honest Aunt Sarah it was an accident I swear." She looked at me and said "But you did enjoy it didn't you, I could tell." I said "What do you mean you could tell?" She reached out with one hand and grabbed.
