Your nephew, Darius is half Puerto Rican (his father is a Black Puerto Rican) and a few months ago he got the opportunity to visit Puerto Rico and meet some of his family that still lived on the island. As he tells it, he was spending time getting to know his older cousin, Tania, who lived in the country and he was having a nice conversation with her and her friend Milagros aka "Millie" (both in their early to mid 40s).
Millie asked him had he ever tried "Quenepas" (there a small fruit that resembles a lime, but smaller and they're sweet and you usually suck the juice out of them)? She let him try one and he liked it and she invited him to go pick some from a tree not to far from the house. Tania figured she would take that time to go into the house and start preparing dinner.
The trees must have been about a 1/4 of a mile from the house and they were still on Tania's property. Now, Darius (who is in his mid 20s) is thinking this should be fun because he's basically a young man who was raised in the city. However, it seemed that Millie had more than just "picking fruit" on her mind.
Darius is standing there watching her and he can't believe that this is happening, in addition he's amazed at how big her nipples are! Furthermore, while she is doing all this she keep saying "Ajustada, Ajustada" (tight).
It seemed that Millie was really "turned on" by the thought of getting caught and Darius just got caught up in the moment.
