Bzzzt. Bzzzt. You glance down at the vibrating oxygen meter strapped to your side and check the readings. -15%- The oxygen levels in this cave have dr...pped dangerously low, despite its spacious qualities. You think better of pushing your luck any further and resolve to head for the surface. You silently thank yourself as you carefully retrace your steps to find the first of the glow sticks you've laid out for the return trip. Idly checking your oxygen meter once more to find it has dropped yet. My sister was held by the two bitches. Now naked except for the small pair of white panties that covered her cunt. Her tiny tits were round with little fat to them and her nipples stuck out proudly and looked hard. Her face showed the fear she felt. And her eyes were transfixed on Maria.“You ever been fucked Danii?, never had a cock up your cunt?. Never been made to cum by someone else?....well it is true what they say Danii. You never forget your first time and who it was with. So you are. And not just lipstick! She applied some base makeup, eye shadow, eye liner, mascara, rouge, and then finally some cherry red lip gloss. She excused herself returning a few minutes later completely naked except for a 9 inch strap on dildo. She instantly saw the smile on my face. She told me to get on my knees and suck her cock. I hesitated thinking how awesome this was going to be and then she yelled, “Get the fuck on your knees you fucking cheap cunt and suck my cock!” She was serious and. "Well it was all Tom's idea, he caught me skinny dipping and threatened to tell you and mom if I didn't sleep with him." So let me get this straight," I began, "you slept with the neighbor's son to keep him quiet, not because you liked him?" Well I didn't want you or mom knowing I was skinny dipping, besides I lost my virginity a couple years ago and kind of enjoy doing it."I took a step back on that remark, "You enjoy doing it?" I asked."Well yea, what girl doesn't love getting some guy hot.
