Robin savoured every flavour of Abigail's overflowing cunt, slurped, sucked and licked, completely enthralled by their professor's taste which sent so much sexual energy through their body, from their tongue down to their own cunt which was gripping the saddle of the RealDoe tightly. They just wished they could have seen her face as well. Abigail's pleasure face was such an exquisitely beautiful and arousing sight. They were barely aware of anything else around them until Xavier pulled them back and pulled most of their shirt off before he stepped between Abigail's legs.<br/><br/>They watched as he wet his throbbing cock in his wife's slit and removed the rest of their shirt, tossing it on the floor. They then leaned in closer for a front row view of Xavier's cock slowly disappearing into Abigail. He was in no rush to get it all the way in, letting her feel every inch of it as it opened up her leaking cavity. They were pulling lightly on the RealDoe with one hand and let the other hand explore Xavier's surprisingly firm ass, but then again considering the work out they had done together Robin couldn't actually say they were surprised. He kept himself fit. They ran their hand down his thigh and back up on the inside until they felt his testicles in their hand. They gave it a little squeeze and leaned in even closer so that when eventually he pulled out his cock, now glistening with Abigail's juices, it almost slapped them across the face.<br/><br/>It was such a beautiful sight and Robin didn't need any encouragement before they ran their tongue along the full length of Xavier's cock. The taste was unmistakably Abigail's but there was that underlying salty hint of fresh sweat and blood-filled flesh. They moaned and wrapped their lips around the shaft sideways, sucking on it the way one might suck on a cob of corn to get all of the sweet juices out before biting down. Luckily for Xavier Robin didn't bite down they just nibbled gently along the shaft to the neck of the glans. They could smell the pungent scent rom the glans and the took a deep sniff, the way you might if someone asked you to smell some kind of delicious food. Their hand was still on his testicles from behind, massaging them, giving them tiny little squeezes and the thumb moved up and down along the crack between his buttocks. There was no actual intention at penetration even if perhaps it might be perceived as such. Robin certainly hoped that he wouldn't be entirely adverse to having his anus played with and licked.<br/><br/>At the same time they pressed their tongue against the frenulum and wiggled it sideways before slowly running it up to the very tip of the glans, poking it at the tiny hole and then, having now cleaned all of Abigail's taste off of it took it with their free hand and guided it back to her cunt.<br/>"I want more, please ..." they said and took a firmer grip around his testicles as if threatening to hurt them if he didn't push his cock into his wife again.
