A big smile spread across Robin's face when Xavier joined in their little roleplay and the hand on their head, the rough grip of their hair, felt just right and fuelled their submissive role. At first, if only for a brief moment, they thought he would go the impatient route and simply fuck their mouth. His words certainly seemed to indicate as much. When he didn't they smiled again and looked up at him with a nod before continuing to tease his cock, taking it a bit more into their mouth but never more than a quick suck or two. They let their tongue do most of the work, licking his glans as if it was a clitoris, running their slightly parted lips along his shaft, pressing it against their hand while continuously tickling and massaging his testicles. When they noticed an increase in the volume of precum, signalling that the big load was on its way, they carefully, almost dutifully, closed their lips tight around his glans and began to suck on it as if it was a lollipop. Their tongue pressing against the frenulum until he filled their mouth with a sizeable load which they swallowed down and then moved back into the visitor's chair with a smile like the cat who ate the canary.<br/><br/>"Your wife did a pretty good job on me earlier so I'm good really," they said realising that they wouldn't have that much time for anything else anyway.<br/>They then shrugged at his question about whether they had plans later that night or not. They didn't really. Well, apart from studying and their usual evening run. Other than that they would probably just end up reading a bit or watching a tv series, or if inspiration struck them do some writing.<br/><br/>They could of course run the new route they had found that weekend, the one that took them close to the farm house where their two lovers lived. A smile spread across their face as they imagined themselves leaning up against a tree with Xavier on his knees pleasuring them orally almost like a brief intermission dividing their run into two halves. He had done more than well with his tongue when properly instructed and they were sure that he would try to improve on it. They were also curious because of Abigail's comment that Xavier's oral ministrations had felt like it was them and not him. Their smile spread as they couldn't help but wonder what that would feel like.<br/>"I usually go for a run just before curfew," they said and bit their bottom lip seductively.<br/>They explained to him that at a certain point along their route they came within visual range of his and Abigail's house and if he wanted to they could meet in the woods for him to give them oral.<br/>"A quick clandestine hook up. If you can sneak away from Abigail without rousing any suspicions on her part."<br/><br/>They then picked up their bag, thanked him for the coffee and before leaving his office gave him a quick affectionate kiss on the lips.<br/>"I'll text you when I head out," they said and walked back out onto the street, lit a cigarette and headed for their dorm.
