I look over and see the woman in the office is still head down and concentrating on her paperwork. Thu follows my eyes and swivels her head around to look at her as well, then turns back to me and raises one eyebrow.
My hands are still around Thu's waist, and so I release my right hand and put it between her legs. My hand moves up between her thighs and I start rubbing her mound. Thu arches her back in pleasure and closes her eyes. I keep my eyes on the office woman but she doesn't seem to notice us so...
I untie Thu's bikini bottom completely, and pull it out from under her. The bikini waves in the flowing water and so I release it, watching it flutter for a second until a current catches it and the uplift causes it to float around on the surface of the jacuzzi like a fallen leaf.
Oops.
Well if I'm going to get caught, I might as well make sure it's for something good. I grin at Thu and move her in front of me. I caress her thighs then reach between them to penetrate her with my right thumb. Thu uses both hands and tries to push me off but I just smile.
"What are you doing?" she whispers urgently, trying to conceal the look of panic on her face. She looks around once then again, swiveling her head to the left then to the right, but no one's watching.
Without looking, I pull my thumb out and line up my dick at her pussy entrance. A quick glance shows that the office lady is not at her desk.
Oh shit! Is she calling the cops? My mind begins to race.
But seconds later, the office lady returns to her desk. Better yet, she turns away from us to face her computer and starts typing.
Close call but luck is on my side and so I ride the wave. I take the opportunity presented and grab the head of my cock and put it back at the entrance to her pussy, then I tense and penetrate Thu with one thrust. Thu gasps and bites her lip, enjoying the sudden fullness in her pussy. She begins to rock back and forth a little but keeps her eyes on me. She knows we could be watched and doesn't want to make it obvious. Out of the corner of my eye, I see the office lady still focusing on the computer. Keeping my eyes on her, I push my index finger into Thu's ass. She clamps down and I can feel her squeezing both my finger and my dick at the same time. It's hard to be subtle and so I lower us both deeper into the water.
I reach around with my other hand and find her clitoris and start rubbing circles on it. Thu starts moaning and whispers in my ear, "Fuck me... I want you to fuck me so badly..."
I rub her clit harder and she begins to shudder, mouth open, eyes closed. She bucks her hips, once, twice, then crumples into my arms.
"Oh that felt good," she says. "I don't know how you do it..."
I look around and see the office lady standing at the window, looking at us suspiciously.
"Time to go," I tell her. Trying not to look obvious, I grab Thu's bikini bottom and submerge it into the water. Thu takes it from me and puts it back on hastily. Together we slowly climb out of the water and head towards her apartment, but Thu's bikini bottom falls open exposing her pussy to anyone in the apartment complex who happens to be watching us at the time.
"Oh shit!" she says as she quickly bends over and walks awkwardly to the lounge chair with her thighs together. She grabs the robe, and under its cover, ties the bikini bottom properly and together we walk briskly back to her apartment complex.
Our backs are to the office lady, but that doesn't stop us from feeling the heat of her glare until we're out of her line of sight.
"Paying next month's rent may be a little awkward for you," I suggest.
Thu stares at me feigning anger, shoves me into her apartment, and has her way with me in the living room.
The irony is that she never got around to closing the front door.
