He could feel the slight hesitation on the part of Amber, perhaps even her shame as he pushed his hand higher along her leg. He nearly grinned at the protest of her friend in the back. The responses to his actions were clear. Her driving was less concentrated, she'd surge the car, then slow down, little control as his fingers caused an effect. But she followed his demand perfectly. Where Sera might have bucked, challenged, Amber immediately opened her legs up for him to gain more room. For the moment he didn't care even if the brunette got a coughing fit. She was pushing her hips down at him, trying to gain more penetration, giving him an angle to push deeper. That meant on that first push he already was able to find the slightly rougher patch that was that inner gspot. Now the trick was to hit it with each deep push of his fingers into her, to make sure to keep pressure on that clit with the top of his palm. She moaned, he grinned.<br/><br/>Sera was looking at him as if she could kill him. For a second he thought the amount of conjuring back in the park would make them all lose control. A fine line between lust and rage, especially if lust wasn't doused by a heavy bout of sex... He chuckled though, when she called him a genius. He didn't respond to her question, it was certainly retorical. Well... he didn't respond with words. Cause as Amy parked the car, he started jamming his fingers faster, deeper, harder. Immediately after Sera had spoken to him. To make sure she knew what the hell was going on in that front seat. His right hand inside the track pants of her roommate, his body leaning half over her, watching the brunette.<br/><br/>His left hand extended towards Sera, slipping straight into the dark locks as he pulled her forward. A whisper, audible for both of them. "Let me get this little slut off first...". Then his lips mashed against Seras. Kissing her deeply. Tongue dueling with hers over control. Moaning into her lips. The moan more from the way her friend clenched around his fingers. His lips pulled back, Jacks warm vibrato coming to them again. "Help me Sera... slip your hands over those lovely breasts... lets make her cum together.". He pulled slightly away from the brunette to focus more fully on the strawberry blonde again. His movements inside of her were harsher now. "Fuck... you're so tight..." he spoke. "Going to feel so good on my fat cock....".<br/><br/>Suddenly he withdrew his fingers though, the back of his hand pushing her clothes away a bit to make room. His left hand coming in to aid. Pulling the clothes down over her hips, just enough to lessen the constraints, not baring her up. His right hand then slapped at her clit, fingers hitting her outer folds. Those pads of index and middle fingers running over her, teasingly, before hooking back into her. Immediately as he slipped in, he started fingerfucking her again. The slow, gentle start had gone now, wanting to get her off. Wanting to get inside the house. His left hand wandered up into Ambers hair now, Taking a fistful of it, slowly straining it, to pull her head back slightly. "You're going to come, aren't you Amber?".<br/><br/>Those fingers pushed deep, with a little twist to the right, withdrawing while twisting back straight. All done to hit as much nerve endings as possible. He was pushing himself up too, knee of his left leg in the seat, the painful foot dangling in the air, right foot firmly planted on the floor of the car. In this position he could use more precision to do what he was doing. "Goddamnit... I need to fuck you two..." he again spoke up.
