He took me aside and explained, as he had mentioned earlier, that he was 100% straight and that while eating her pussy full of his cock and cum that I... was not to touch his cock or balls no matter what. I explained to him that it was going to be impossible not to make some incidental contact with him. We agreed on that and she came into the room.She laid on the bed and watched us as we removed our clothes. He instructed me to eat her pussy while he watched. I complied with vigor! Sucking her. From there she licked it up and down it felt amazing! From there she went on to lick my balls and suck on them I thought I was going to blow but thankfully I did not. She said she was ready to put me inside her. She then looked around for condoms we had brought. We had messed around in the pool without any but since she wasn't on any birth control yet she wanted to use a condom for the full out sex. She slid one on me and I laid her on her back we kissed a few times before I gently entered her. Every mother of a boy knows this. And in the bathtub, it's very common.I did what most parents do, I answered his questions about his body or about sex when they came up, trying to honestly answer them while also trying to keep from telling him too much each time. If you have children, you know.So, he was fairly young when I explained his erections, older when he asked me where babies came from, older still when he asked what my tampons were one afternoon. Yes, there were times I surely wished. Another hour was gone now.Moana and me tried to relax and get back our breath. All over sudden one of the black guys slowly spreaded Moanas legs shouting to the other guys. What we saw was that now some drops of cum were dripping out of Moanas cunt. Obviously the black guy was quite naughty because now he began to split Moanas lips in order to see more cum coming out of her. Moana was saying nothing and let him proceed. The black guy now started to give her clit a slowly massage, using the cum.
