First Interaction

As S1 and S2 are just 18, their moms decided to give the boys a basic idea. As they are from a tribe and they are directly related to the boys, moms tried hard explaining the boys indirectly with some limitations. The boys doesn't seem to have caught anything. M1 and M2 decided to take the hard way to teach them. They undressed, and the boys got boners seeing such curvy bodies walking towards them. M1 started making out with S1 and M2 with S2. The session ended with penetrations and the boys got a fair idea on what to do.

The Ritual

The native people of the island followed few strange rituals before mating. One of the strangest ritual is the women has to compete like animals to win their mate. Both M1 and M2 entered the battle ground and the boys S1 and S2 were standing nearby to observe the fight between the two voluptuous women. S1 shouted from one end stating, "let the fight begin, the greatest warrior get to be hold my lineage". Although M1 and M2 discussed already on what and how the fight should end, the boys were not aware of it. The curvy women started the fight and their jiggling flesh and sweaty skin made the stick straight for the boys. The fight ended with M2 winning M1. Learning about the plan of M1 and M2, S2 announced this time for an another match and M1 defeated M2.

Price for the winners

Seeing the Rubenesque figures battling ferociously, the dick of the boys were about to pop. As soon as their mates came near the boys started making out. M1 started blowing S2 and seeing it M2 also started blowing S1. Following the blowjob the boys made the women lay next to each other and penetrated them. Having the best moments of his life S1 suddenly got an idea and asked M2 to hold the hands of M1 and stand in a kneeling position facing M1. S2 got the crux. Their marvelous mammaries and the curvy body were clashing tightly and the boys started penetrating from behind. M1 and M2 kissed each other as the boys penetrated. After awhile, S1 kissed M1 from the shoulder area of M2, S2 also did the same to M2.

The Unswap

Both the boys and the women became much comfortable with each one. Both M1 and M2 wanted to go for an unswap. The boys tried every possible individual interactions and multiple interactions like dual blowjob, double penetration, etc. with their mates. The boys wanted more of it and hence they decided to complete the session with a cumshot, instead of depositing the load into the womb. They ejected on the bodies of their mates and the women started licking it and performed a naughtier cumswap before swollowing it.
