You recognized her partner

You wanted to turn around and walk away, so you wouldn't get more turned on by the sight and moans, as you noticed something. Two hands reached around Chaz' waist. Which may sound quite normal in that situation actually wasn't. The hands looked boyish with short nails, but the nails were painted. And not just some nail-polish. It was a silverish golden, just like the favorite one of somebody you knew. Carefully you took steps forward, so you could see the person Chaz had sex with, and your fear was confirmed. The small, round face with the full lips and petite nose with perfect make-up, short boyish hair and a boyish body below it clearly belonged to Frank. You were really shocked seeing that the one boy of your group, who you considered the smartest, had given in to the sex-hungry Chaz.

Quickly you hid yourself around the corner, so they couldn't see you. You needed some time to process what you just had seen. Was that really Frank having sex with Chaz? You looked around the corner once more and confirmed that you had seen right. But even the second time didn't proved you wrong. It was really so. Frank was having sex with Chaz, who was the active one.

You looked a third time, but it was still the same. Chaz was still on top of Frank, riding his cock and making sexy moans. But, unlike the two times before, you couldn't avert your eyes from the two. Subconsciously you moved your hand down to your pants and took your erect penis out. You began stroking the totally hairless shaft while looking at the sexy sight of Chaz's big butt and huge breasts bumping up and down while a big cock slid in and out of her pussy. It was a very sexy sight and while you masturbated you wondered what it would look like from the other side`? What Chaz' aroused face looked like? How her huge breasts looked like bouncing up and down right before your eyes? How her pussy would feel on your cock?

You didn't realized that you desired to be the one fucking with Chaz until came huge. You shot a big load through the air, which splashed onto the floor. The splash was drowned by Chaz' loud moan as she orgasmed. Her hips twitched a few times and some white stuff flew out of her pussy and down Frank's dick. Not only did Chaz had an orgasm, Frank too had cum inside her.
