Seriously, I am proud of you!" Thank you. Your praise means a lot to me. Can I safely wear the shield all of the time, or are there times when I shoul... take it off?" You can wear the shield as much as you like. It will not harm you, though you may want to take it off when you are bathing, so that you can enjoy the feel of the water directly on your skin." OK, I'll keep that in mind. Is there another skill that you can teach me?" Not now. You need to practice your current skills until they are. Luckily there wasn't any incidentthat was bad and soon the couples had returned home."Thanks for a wonderful evening Tiffany," Mark said."I had fun, goodnight Mark," Tiffany said."Thanks for being a nice brother Mel, I had fun too," Brenda said."Me too, you're pretty cool for a sister, goodnight girls," Mel said.The girls went into their room and removed their clothing and makeup."Your brother is very nice, and cute too," Tiffany said."He is nice, but I don't know about the cute part," Brenda. He asked if she was going to tell me, she told him no, she didn't think I could handle it if it actually happened. She then got up and lay back on the bed and removed her panties put a couple of pillows under her head, he said he knew she was wanting to see his black cock going in her. She told them that this was going to have to be quickie because she was usually home already. He said he climbed between her legs and she reached down and guided it toward married white pussy. He told her to lay. Mindlessly, he thrusts forward, the tip of his cock sliding unsuccessfully beneath her entrance, rubbing against her clit. The hot scarlet of his jabbing penis contrasts vividly with the fevered pink of the girl’s passion-inflamed cunt, spreading her lips wider as his still-exposed shaft rubs between them. I hold my breath with the other spectators who have stopped to watch the huge dog, bucking madly behind the moaning girl, attempting to skewer her on the still-lengthening taper of his.
