She stood there and started to unbutton her blouse before I told her, “Wait a minute, that’s my job”. We lay on the bed together and began makin... out again as I continued unbuttoning her blouse. She shed her blouse and pulled down one bra strap. I pulled down the cup and began to gently suck and lick her left nipple. She squeezed it for me, as if feeding a baby. It was obvious to me that she considered her breasts as one of her best assets. Together we removed her bra and went back to kissing. Of course, it was neither possible nor desirable to hide all of the physical changes that had taken place. The tiny black lace bra, for example, no longer fit at all, so her upper body was covered only by the translucent lace top, which now barely covered the nipples on her enormous udders and left her midriff bare. Likewise, many of the other modifications had changed her appearance somewhat, but it was certain that everyone present would have no problem recognizing her from her pre-slave. “Is it ok sir if we masturbate sir?” Brian asked pulling his trousers right down, “That cuddle with your daughter sir is so hot sir” Simon added and now they both had their trousers around their ankles as they sat watching.I had to break off from my kiss to answer them, “Sure boys” I replied and Suzy kept gyrating so I managed to work my fingers between her legs to move her panties aside, “Fuck me daddy” she whispered into my ear and as I manoeuvred my cock out of my shorts I could see the boys. We were bumped around a little in the tops of some building cumulus clouds, but there was no lightning in any of them. Nelda was an excellent companion. We talked about a variety of things. She told me all about her husband and her three kids. They had all died at one time or another, leaving just her. She was a tough old bird; she didn't give up, and just kept going.We made the trip without a stop, with all the passengers using the potty. An ambulance met us at the ops building. I told them.
