Robin's somewhat faked moans did at least have the effect of boosting Xavier's confidence as he worked somewhat dutifully on their vagina.  It was almost impossible to imagine Abigail in a similar situation, pants around her ankles in the passenger seat of the truck.  Or was it his limited imagination that made him assume that?  Had he simply assumed way too much, or maybe too little about his wife?  Following her progression he was again rewarded with a 'fuck yes' and talk of being 'close'.  Robin was so much more upfront with what they wanted than his wife, but would his younger self have taken such instruction during sex or whatever this was?  What he did know, was that Robin's body and words were making him painfully hard, his balls felt like they might explode if he didn't get relief soon.  He did pick up the pace though and had a proud look on his face at her orgasm, though he might have been dismayed to know how she ranked it.<br/><br/>"You did seem to like it."  He said as Robin told him it was 'not bad'.  But seemed to look around and realize what a position of inferiority he had found himself.  He didn't protest but it was clear he wasn't in his comfort zone on his knees before them.<br/><br/>He was happy to crawl out of the foot well and stretch out onto the reclined seat, happier still to watch Robin contort themselves out of their jeans and pull down his jeans and underwear.  His cock was painfully hard and he moaned as Robin began licking his cock.  "That's good, it feels great."  He told them but stopped talking as their lips encircled his glans and began to take more of him.  Robin was correct to surmise that he wouldn't last through much of that.  Seeing that pretty boy face at the end of his dick was almost as good as the feel of it.  But then they released him and straddled him properly.  He had almost forgot the 'non-penetrative' part of the lesson and was a little confused as they reverse hot dogged him with those warm wet lips.  It wasn't what he expected or wanted, but it felt undeniably good.<br/><br/>"Oh man that feels good."  He said, though made no inquiry as to how it felt for them.  The long slow strokes were nice but as they focused their clit on his glans he could feel his climax beginning to build past the point of no return.  He looked at them intensely, every male instinct wanting to thrust deep inside of them.  He reached up and pushed the unbuttoned shirt off their shoulders, pulling down their arms and back.  But instead of letting it fall off, he gripped the cloth with both hands, wrapping it about them before gripping their waist just above the hips.  He effectively bound their arms to their sides, setting them more upright as he began to take control of their lower body.  He used his strength to pull them down harder upon his cock still pressed along his belly.  He then rubbed their cunt along his shaft at his own rhythm now, breathing hard at the arousal and effort to control them. He looked up at those small pert tits, picking up speed and effort, enough to make them jiggle slightly from the motion, even if the lacked the mass of Abigail's larger breasts, it was still a sexy sight.<br/><br/>"Oh fuck"  it was his turn to curse as his cock shot forth a thick powerful jet of his cum.  That first big pulse blasted onto his face and neck, the second striping his chest, oozing into the hairs, several more lower across his belly.  He then oozed even more just out of the tip forming a puddle that seeped back along his shaft and into his navel. He grimaced at the self facial, clearly uncomfortable with even his own cum on his face, but still holding their shirt there wasn't much he could do about it but keep his lips closed.
