Sex instead of quantum theory

Spending a lot of time together, the two attractive girlfriends go shopping, party, and study. Even though they enjoy having fun, they occasionally have to stay inside and tuck their lovely noses into old books. Nevertheless, they had to stay at home on Friday night to do their assignment on quantum physics. Despite their hard work, their gorgeous heads are occupied with thoughts of boys, parties, and clubs. When all else fails, they give up and call their friend to ask for assistance. He demands something hotter in return for his assistance, even though they promise him mountains of gold. Yes, he does assist them, but he also baits them with his large dick.
