”Oh, shit,” I muttered unhappily, looking down. As we had recalled that morning, I’d gotten quite an erection. It was standing up, engorged.”Y...ou’re excited right now, right?” Lacey looked up at me.”I’m sorry,” my face reddened, “I should go calm down.”I started to get up, and Lacey stopped me, “It’s okay, daddy. I want to see it like that.” I badly wanted to go calm down. They shouldn’t see how much they aroused me. That was way deep into the forbidden. But apparently they didn’t want me to go. Before she got out she told me that she got wet from watching me and that she was going to go jill herself off in her panties and wear them for a couple more days before giving me a call to pick them up! I offered her the $20 but she refused and said masturbating in front of her was payment enough!! I did meet up with her a couple times after, and we did the same thing as the first time, but when I invited her back to my place she declined and never called me again. I did see her once around. Mean time, my sister’s hand was busy in her husband’s crotch. Ho! When he turned back, I was taken aback to see his huge penis! Though it was not a clear view through the key hole, It resembled a big banana or a cucumber!. It was for the first time I saw a man’s erection. My sister started to suck it gently at first and vigorously afterwards. Suddenly he lifted her to make her sit in his lap. He widened her well shaven vagina with his fingers, while se guided his penis head into the hole. After. Over time we struck quite a friendship with the owner, Ed. We found out recently how much so, when he presented us with an invite to a private party at his apartment, above the shop. This was an invite to an ‘anything goes’ party, for selected friends only. On discussing this with him he explained that it was for about 20 people and was an opportunity for us to further explore our fantasies and desires. At first Nina completely against the whole thing, but over the coming few weeks she was.
