Walk home.

You start to think of everything that can go wrong with staying here, and sadly withdraw your offer. Your place really is close to here. It should be fine. You made it to the park, and because of Troy's talents, you're feeling refreshed and confident.

You walk. The panties bunch up and slowly glide across your labia like an extra-teasing extra-tight thong. Your lips quiver (both kinds) as you move down the block. Your face burns red and you glance in a paranoid way back and forth as the people walking past you. They don't know. You remind yourself of that, and keep going.

Probably a minute from an orgasm and you arrive outside your door. You knock and eventually your sister answers, eyeing you curiously.

"Well, my favourite and only sister has returned. Did you have a fun day?" She winks.

Does she know? You shrug and say you just really want to come inside and relax.

"Mhm... I bet." She beckons you inside. You step into the living room and kick off your shoes as the door closes behind you. You begin to worry that she's noticing the struggling way you move, and the small moans you make through your heavier breathing.

"I was just watching my show all day. Come watch some if you want, after you... rest." She snickers as she proceeds onto the couch.

As you wobble towards your room you hear, "How's the underwear fitting?"

Your brows furl and you turn to face her--face red with both desire and anger. She smiles, and you turn to slam the door into your bedroom.

You undress to nothing and start to look for something more comfortable to wear, but you're so very aroused. You have this sinking feeling however that your sister is listening. Can you afford a quick finishing of your self?
