Gwen wants to play!

You were in the middle of stammering a weak excuse when Gwen interrupted.

"You fucking horn dog..." she said with a growing smirk on her face. "I told you to wait for me, we're supposed to share."

Eric didn't seem phased at all we he began to pull your panties down over your hips and letting them drop down with your shorts, his free rubbing over your stomach. "Just getting her ready, babe." he said calmly, lust still dripping off his voice.

You couldn't believe what was happening. In front of your eyes your sister was stripping down, dropping her own shorts and tossing her shirt over her head as soon as she had locked the changing room door behind her. This was going too far! You couldn't have sex with your sister, even if you were a girl! You opened your mouth to end this only to have it drowned by a sudden moan as you felt a sudden shock from your loins. Your sister had slipped to her knees and was eagerly flicking her tongue over your soaked pussy lips. Your SISTER was eating you out!

"Haha, you little slut!" Eric laughed in approval as he worked his pants off and tossed them with onto the growing pile of discarded clothing. Your hips were thrashing under your sisters all too masterful tongue as you tried to keep your balance and stay standing, **** to lean and hold onto your sisters shoulders just to avoid falling over. From the corner of your eye you saw Eric sitting back on the bench, watching you both with a hungry gleam in his eyes, his left hand stroking over his length while he did.

"I think she's good and ready. Bring her over." He commanded in his usual confident tone and your sister was all too eager to oblige, pulling you over to him by your hips while crawling over.

"What do you want to do, baby?" she purred, still on her knees as she stroked his thigh with one hand and still holding you close with the other.
