You both sit there, giggling with anticipation one hand ministering each others genitals, the other clasping a big fat reefer, already you both feel a little dazed, the result of good quality skunk and a wondrous fuck; but now it's time for the show.
The two naked bodies in front of you, one lying prone the other kneeling are both sheened with sweat from earlier exertions, muscles pumped and sinuous. The prone figure has a hard on which pulses slightly under the pressure of the blood swelling it, purple and veined, the circumcised tip glistening with vaginal juice and cum.
The owner of this throbbing cock has his arm out in Jack's lap and is slowly, languorously, rubbing his engorged prick forcing moans of pleasure. Jack's hands, likewise stroke the soft skin of his first bi mans inner thighs, working slowly up towards his sensitive anus and balls, engulfing them completely and moving onwards up the stiff shaft. Seemingly drawing it up, further increasing its size.
The girls have grown quiet contemplating this scene, their hands still rubbing each others now sodden cunts, neither have seen this before, they tense as Jack lowers his head towards the glistening glands, he opens his mouth wide and the top half of the cock disappears, but he does not suck, he doesn't even touch, just breaths warmly, sending a caress of warm air over this living, iron-hard rod of flesh, his victim shivers and groans raising his hips slightly.
