The three left the bar and turned down the alley. When they got to a dead end she smiled at Mack and walked towards him. "So, are you going to take your pants off or do you want me to do it for you?" she asked. He feigned a bit of confidence and said "What the fuck do you think, Jessica?" She smiled and bent down under him. She undid his pants and planted kisses on his horsecock. Mack winced as she tried to massage his balls. "You've been a busy guy today." she said jokingly as she saw how red they were. It was then that he used the app to fix Mack's balls. When he came back she looked shocked. "Holy shit Mack! They went from red to black in a fucking second. Are you okay!?" He sighed in relief and said "I was always okay. The light must be really shitty down there or something." Jessica shrugged and continued massaging the balls and kissing his cock. It took a minute for him to get half hard. Alex's curiosity got the best of him as Jessica looked like she was surprised it was taking so long. Mack had his eyes closed and shifted bodily as he tried to get into it.
He checked the calibration between them using the app. The net compatibility for them on Mack's account was 52. It would just be average sex with them on his end. He did not care about how it would feel with her. Watching as he got fully hard, Alex moved so that he could see better. Jessica pulled down her skirt and panties. She then got under him on her hands and knees with her ass up. Jessica then guided his cock to her pussy and pressed it up against her. "It's been a bit since I took a centaur's dick. Go easy on me!" he said. Mack smirked and said "I know you can take it." He then thrust himself in and began some shallow strokes. They then got into the rhythm and Mack sank a bit deeper. Jessica moaned as she cupped her breasts and said "F-fuck! Harder Mackie." He just grunted as he got even deeper inside her. He was a bit before halfway in, but even that was over a foot long dick inside of her. He had a stressed look on his face. "C'mon! Don't get soft on her. I ain't a fag!" he murmured it to himself. Eventually he came, but it looked like it was nowhere near as much as with Alex.
