In this scenario,
Peter North engages in sexual relations with his pal's spouse while his buddy is intimate with his girlfriend. They are both practicing a non-monogamous lifestyle! The women engage in a competition to orally stimulate each other's partner to see who can achieve an erection quickest. Once the men are prepared and aroused, they engage in intercourse with each other's partners with great intensity.
They interchange partners again and resume penetrating until both individuals reach the point of climax. Peter ejaculates copiously on Jewel, producing enough semen to impress even a sperm whale.
