I was up late working and the rest of the house was in bed – I’m sleeping in the lounge room so I’m the last one to go to bed and the first one to get up.

When I was finished what I had to get done I decided I’d go for a late night hottub.  The hottub at the house is in the backyard and since I was already wearing speedos under my jeans I just stripped down and grabbed a towel.  I was pretty quiet and as I got outside I saw the light on in one of the boys rooms.  There are blinds but they weren’t completely closed.  I wasn’t intentionally looking but I saw flesh.  Taking a closer look I saw him sitting in a lazy boy chair and his girlfriend (cute brunette) on her knees, naked except for a black g-string sucking him off.

I was pretty confident that they couldn’t see me outside in the dark so I enjoyed the show despite the cold.  It was really hot and when he blew his load she took it all.

Once I saw him blow his load I was hard as a rock as well as freezing cold so I got into the hottub.  I kinda hoped that maybe they would be keen for a late night hottub and join me but no such luck.

Have you guys ever caught roommates or friends getting sucked off?

I’m not sure I’m a fan to tell you the truth. I love fucking with it on, with the front pulled aside the ‘string’ bit definitely adds to the experience when it slightly rubs my butt hole but for wearing around the house? I’m not too sure.

Do any of you guys wear gstring often?
