FSDSS-534 The couple tried making love while the whole family was away

Ai-chan, my girlfriend, I was a virgin for the first time. She looks simple but has great style and is a very nice girl. However, my love is too heavy... my appearance changes day by day and my sexual desire increases. It's great to be cute and sexy because I want to be liked, but I'm slowly losing control, and I'm becoming a very affectionate and sexual person...
