Young girls sucking to please guys and keep them around. Nipples are successful and attract males. Everyone wants not only to fuck her pussy, but to give her in the mouth and cum after that. It's a pleasant sight - the partner's lips smeared with cum, the drops dripping from the end on her tongue, her breasts smelling of sex. For a man, this picture is the height of bliss. With that, the girl is down, expressing submission and acknowledging his power over her.
The girls were looking for fun, riding in the car. Sometimes they got themselves excited. Apparently they wanted a new sensation, so they offered a threesome to a strange young, handsome guy. After some persuasion and conversation, he agreed and went straight to work. The girls hooked up with him, gave him blowjobs, rolling on top, while two were fucking, the third fondled the couple.
So that's what they do in yoga. I'll know.
