How do you know he is alone? Maybe the girlfriend is just quiet.
go up and offer to help.
I love it when a guy grunts and groans during sex.
My house mate makes groaning noises with each thrust. He takes ages to ejaculate and when he does, he sounds like he is in pain and that there is a lot of effort involved in forcing the juice out of his engorged fuck stick. It helps that he is very easy on the eye - late 20s, 6 feet tall, thin build, croation background with chizzled dark features, lovely hairy legs that would feel great brushing up against you. Last week I was so aroused I lost my balance and fell against the common wall. I thought I was going to be discovered as I made quite a noise, but his fucking did not let up. The next night I was relieved when things continued as normal. Friday night reached a new high as his normal deliberate and controled rhythm was replaced by very loud grunting and snorting. He sounded out of control and uninhibited as his thrusts helped move the bed away from the wall. As he climaxed he let out a shriek. After about two minutes I heard the bed creak as he withdrew and rolled onto his back. Silence..
Nice... Euro guys are hot.
