A female friend misses the last train and ends up staying at a guy's house. While they sleep side-by-side, the man gets excited when he sees a busty woman. When he secretly touches her breasts, the woman seems excited, and when she starts to moan, he takes her under the covers and makes her cum. The other woman, who was watching from outside the covers, also seems aroused and sneaks under the covers, leading to a harem threesome where she is dominated by two busty women.
