You drive us back to our apartment, Erin and I holding hands in the back seat, the front of my dress still unbuttoned and Erin's tank top still bunched around her waist, her lace strapless bra pulled up around her breasts just barely on this side of modesty.
To keep the mood going, I lean forward and tap on the side of the front passenger seat to get your attention. You glance back at my hand, now moving into the wet sperm that landed there a few minutes before. I catch your eyes in the rear view mirror and lick more of you off my fingers.
Erin watched me in fascination and pulls my arm to her.
"I've never been with a man," she tells you. "So this will be my first taste!"
You slow down and pull to the side of the park road and turn your head, watching her lick your essence off my fingers. You reach back and pull my arm towards you, cleaning my fingers of the last few drops. You nibble on my pointer finger tip, just enough to make me feel it.
"I want to bite on your nipples like that," you say to me, making me moan and my nipples tighten.
Erin immediately notices and reaches inside the top of my dress to play with them. I adore my nipples being pinched and bitten and sucked on, and she loves doing all of those things. She strums her fingers over one, and then the other, pressing a little harder as she feels my nipples harden even more. She suddenly pinches and twists one nipple, hard and I cry out in pleasure. You glance again in the rearview, seeing my head tossed back, my blond hair streaming over the seat, my eyes staring wildly up at the ceiling.
Still keeping that nipple clamped between her thumb and finger, Erin bends her blonde head to my chest and sucks on my other nipple. Her tongue gently laps at it, teasing me between the firm pressure on one nipple and the gentle attention on the other, which drives me wild. You keep watching us, part of your attention on me, and part on the road. Erin leans away from me and pushes my breasts together, asking you if you like what you see over her shoulder.
You sit up straighter to be able to see my chest, now heaving from Erin's attentions. I vaguely hear you say, "Yes, of course, Erin! I'd love for you to nibble on my nipples too!"
Erin looks back at me, grinning and raising an eyebrow to see how I would react.
"Sure," I say. I've never known a guy whose nipples were that sensitive, so it makes me curious to also try to tease you in this way.
Erin runs a hand up my thigh, the frilly white skirt of my dress riding up to my crotch. She looks at my cunt, wet and a little pink where you had fingered me and traces her fingers down my lips, lightly teasing me. I lift my head up, catching your eyes in the rearview mirror. We stare at each other, me getting more and more turned on, and you watching the live porn show between these blonde girls with no apparent inhibitions. My eyes are dilated and it's not easy to focus, but I can tell that both you and Erin are enjoying playing with me.
Erin continues to lightly touch my outer lips for the rest of the ride home, which makes me leave a huge wet spot on the back of my skirt.
She takes my hand as you pull up in front of our apartment and leads me up the steps, watching to be sure that you are following. You are, of course.
She drags me through our living room and down the hall into our bedroom where she pulls my dress, bra and underwear off me and pushes me to lie down on my back on the bed. She quickly undresses and pushes her head between my legs, kissing my inner thighs as she moves up to my cunt. You follow, feeling your cock getting harder again, listening to my moans of pleasure. I look up at you as you walk in the bedroom and watch you as you undress.
